What is Non-Critical Thinking?

Think about the last time you had to take a stand on an important issue, or make a decision while not knowing all of the facts. How did you arrive at your position or choice? What was your thought process, and why do you believe you were right?

We all hope our opinions and choices are correct. However, sometimes our ideas are based on feelings or logical fallacies, rather than facts and solid reasoning—in other words, non-critical thinking.

Non-critical thinking can lead to poor choices, self-limiting beliefs, and (to be blunt) gullibility. You’ll be vulnerable to misinformation and manipulation, because you can’t think for yourself. Let’s look at what is non-critical thinking versus, and how you can break free from it.

Curiosity vs closed-mindedness

Critical thinkers recognize that an issue may be more complex than what it seems, and that there are different ways to look at it. That’s why they always gather facts and check the authenticity and authority of the source. They listen to other views, and fairly evaluate each side.

Non-critical thinkers choose a side, and select facts that support it. They may talk to others, but only to engage in debate (“proving I am right”) than dialogue (“listening, learning, and collaborating”).

That’s why the first step to critical thinking is to suspend judgment: don’t believe everything you’re told, or even everything you feel. Before you react, research.

Reasoning vs emotions

The Foundation of Critical Thinking says that critical thinking is an intellectual disciplined process that involves different reasoning skills, such as:

• Articulating the questions or issue in a clear way
• Gathering information by observation, experience, reflection, communication, or research
• Analyzing, synthesizing and evaluating the information
• Making a choice based on facts, or insight arrived from weighing different pros and cons

In contrast, non-critical thinking is based on emotions, peer or social pressure, tradition. When asked for reasons for their stand, they may say: “It’s always been this way!” or “This is what my heart tells me.”

They may even become emotional when they are asked to explain their side, i.e, becoming defensive or aggressive.

Being aware vs being confined by biases

Everyone has biases, and it is impossible to be 100% objective. We are influenced by our cultural and religious perspectives, personal values, childhood experiences, and the limitations of our knowledge.

Critical thinkers are aware of these biases. Thus, they are always reflecting: “Am I resisting a certain idea? What perspectives am I missing? What are motives for believing this to be true?” So even if they can’t escape all their biases, they can question them and make a rational choice.

Non-critical thinkers are not even aware of their biases, and actually think what they initially believe is a universal truth. This attitude prevents them from asking questions and accepting other viewpoints.

That is why the question “What is non-critical thinking?” can actually be a breakthrough. Once you’re aware that there may be flaws or limitations in your thinking process, you are already opening your mind to new possibilities.

Sound reasoning vs logical fallacies

Critical thinkers strive for clarity, accuracy, and fairness. They want to make sure that their ideas are based on facts and sound arguments.

Non-critical thinkers present arguments, but these may be riddled with logical fallacies. Examples of common fallacies are:

• Ad hominem. Personal attacks against the other person
• Appeal to force. Using threats, or inciting fear, to make the other person agree
• Genetic fallacy. Saying something is true (or false) because of its origin
• Appeal to tradition. Accepting a belief or behavior because people have always believed it or done it
• Argumentum ad Populum. Appeal to popular opinion, usually citing trends, influential people, or universal values such as patriotism
• Appeal to emotion. Inciting pity, sympathy, outrage, or other strong emotions
• Begging the question.  Using claims or facts that have yet to be proven
• Hasty generalization. Saying one thing is true based on limited examples or evidence
• False cause. Claiming a cause-effect relationship that has not yet been proven
• Straw man. Disproving an argument by exaggerating or oversimplifying it
• Slippery slope. Saying if one thing will happen, the second or third thing will inevitably follow

There are many other logical fallacies that can emerge from non-critical thinking. Study them further in order to protect yourself from misinformation, or guard against fallacies in your own reasoning process.

What is the effect of non-critical thinking on my life?

The question ‘What is non-critical thinking?” is very important, because faulty reasoning abilities can have a huge impact on the rest of your life.

It can cause you to make dangerous errors in judgment—at work, and in your personal choices. It can lead to missed opportunities and misunderstandings. It can even hold back your career, because critical thinking is essential in management and leadership roles.

Rethink the way you think, and start learning how to develop your critical thinking skills.

41+ Critical Thinking Examples (Definition + Practices)

Critical thinking is an essential skill in our information-overloaded world, where figuring out what is fact and fiction has become increasingly challenging.

But why is critical thinking essential? Put, critical thinking empowers us to make better decisions, challenge and validate our beliefs and assumptions, and understand and interact with the world more effectively and meaningfully.

Critical thinking is like using your brain's "superpowers" to make smart choices. Whether it's picking the right insurance, deciding what to do in a job, or discussing topics in school, thinking deeply helps a lot. In the next parts, we'll share real-life examples of when this superpower comes in handy and give you some fun exercises to practice it.

Critical Thinking Process Outline

Critical thinking means thinking clearly and fairly without letting personal feelings get in the way. It's like being a detective, trying to solve a mystery by using clues and thinking hard about them.

It isn't always easy to think critically, as it can take a pretty smart person to see some of the questions that aren't being answered in a certain situation. But, we can train our brains to think more like puzzle solvers, which can help develop our critical thinking skills.

Here's what it looks like step by step:

Spotting the Problem: It's like discovering a puzzle to solve. You see that there's something you need to figure out or decide.

Collecting Clues: Now, you need to gather information. Maybe you read about it, watch a video, talk to people, or do some research. It's like getting all the pieces to solve your puzzle.

Breaking It Down: This is where you look at all your clues and try to see how they fit together. You're asking questions like: Why did this happen? What could happen next?

Checking Your Clues: You want to make sure your information is good. This means seeing if what you found out is true and if you can trust where it came from.

Making a Guess: After looking at all your clues, you think about what they mean and come up with an answer. This answer is like your best guess based on what you know.

Explaining Your Thoughts: Now, you tell others how you solved the puzzle. You explain how you thought about it and how you answered. 

Checking Your Work: This is like looking back and seeing if you missed anything. Did you make any mistakes? Did you let any personal feelings get in the way? This step helps make sure your thinking is clear and fair.

And remember, you might sometimes need to go back and redo some steps if you discover something new. If you realize you missed an important clue, you might have to go back and collect more information.

Critical Thinking Methods

Just like doing push-ups or running helps our bodies get stronger, there are special exercises that help our brains think better. These brain workouts push us to think harder, look at things closely, and ask many questions.

It's not always about finding the "right" answer. Instead, it's about the journey of thinking and asking "why" or "how." Doing these exercises often helps us become better thinkers and makes us curious to know more about the world.

Now, let's look at some brain workouts to help us think better:

1. "What If" Scenarios

Imagine crazy things happening, like, "What if there was no internet for a month? What would we do?" These games help us think of new and different ideas.

Pick a hot topic. Argue one side of it and then try arguing the opposite. This makes us see different viewpoints and think deeply about a topic.

3. Analyze Visual Data

Check out charts or pictures with lots of numbers and info but no explanations. What story are they telling? This helps us get better at understanding information just by looking at it.

4. Mind Mapping

Write an idea in the center and then draw lines to related ideas. It's like making a map of your thoughts. This helps us see how everything is connected.

There's lots of mind-mapping software , but it's also nice to do this by hand.

5. Weekly Diary

Every week, write about what happened, the choices you made, and what you learned. Writing helps us think about our actions and how we can do better.

6. Evaluating Information Sources

Collect stories or articles about one topic from newspapers or blogs. Which ones are trustworthy? Which ones might be a little biased? This teaches us to be smart about where we get our info.

There are many resources to help you determine if information sources are factual or not.

7. Socratic Questioning

This way of thinking is called the Socrates Method, named after an old-time thinker from Greece. It's about asking lots of questions to understand a topic. You can do this by yourself or chat with a friend.

Start with a Big Question:

"What does 'success' mean?"

Dive Deeper with More Questions:

"Why do you think of success that way?" "Do TV shows, friends, or family make you think that?" "Does everyone think about success the same way?"

"Can someone be a winner even if they aren't rich or famous?" "Can someone feel like they didn't succeed, even if everyone else thinks they did?"

Look for Real-life Examples:

"Who is someone you think is successful? Why?" "Was there a time you felt like a winner? What happened?"

Think About Other People's Views:

"How might a person from another country think about success?" "Does the idea of success change as we grow up or as our life changes?"

Think About What It Means:

"How does your idea of success shape what you want in life?" "Are there problems with only wanting to be rich or famous?"

Look Back and Think:

"After talking about this, did your idea of success change? How?" "Did you learn something new about what success means?"

8. Six Thinking Hats 

Edward de Bono came up with a cool way to solve problems by thinking in six different ways, like wearing different colored hats. You can do this independently, but it might be more effective in a group so everyone can have a different hat color. Each color has its way of thinking:

White Hat (Facts): Just the facts! Ask, "What do we know? What do we need to find out?"

Red Hat (Feelings): Talk about feelings. Ask, "How do I feel about this?"

Black Hat (Careful Thinking): Be cautious. Ask, "What could go wrong?"

Yellow Hat (Positive Thinking): Look on the bright side. Ask, "What's good about this?"

Green Hat (Creative Thinking): Think of new ideas. Ask, "What's another way to look at this?"

Blue Hat (Planning): Organize the talk. Ask, "What should we do next?"

When using this method with a group:

• Explain all the hats.
• Decide which hat to wear first.
• Make sure everyone switches hats at the same time.
• Finish with the Blue Hat to plan the next steps.

9. SWOT Analysis

SWOT Analysis is like a game plan for businesses to know where they stand and where they should go. "SWOT" stands for Strengths, Weaknesses, Opportunities, and Threats.

There are a lot of SWOT templates out there for how to do this visually, but you can also think it through. It doesn't just apply to businesses but can be a good way to decide if a project you're working on is working.

Strengths: What's working well? Ask, "What are we good at?"

Weaknesses: Where can we do better? Ask, "Where can we improve?"

Opportunities: What good things might come our way? Ask, "What chances can we grab?"

Threats: What challenges might we face? Ask, "What might make things tough for us?"

Steps to do a SWOT Analysis:

• Goal: Decide what you want to find out.
• Research: Learn about your business and the world around it.
• Brainstorm: Get a group and think together. Talk about strengths, weaknesses, opportunities, and threats.
• Pick the Most Important Points: Some things might be more urgent or important than others.
• Make a Plan: Decide what to do based on your SWOT list.
• Check Again Later: Things change, so look at your SWOT again after a while to update it.

Now that you have a few tools for thinking critically, let’s get into some specific examples.

Everyday Examples

Life is a series of decisions. From the moment we wake up, we're faced with choices – some trivial, like choosing a breakfast cereal, and some more significant, like buying a home or confronting an ethical dilemma at work. While it might seem that these decisions are disparate, they all benefit from the application of critical thinking.

10. Deciding to buy something

Imagine you want a new phone. Don't just buy it because the ad looks cool. Think about what you need in a phone. Look up different phones and see what people say about them. Choose the one that's the best deal for what you want.

11. Deciding what is true

There's a lot of news everywhere. Don't believe everything right away. Think about why someone might be telling you this. Check if what you're reading or watching is true. Make up your mind after you've looked into it.

12. Deciding when you’re wrong

Sometimes, friends can have disagreements. Don't just get mad right away. Try to see where they're coming from. Talk about what's going on. Find a way to fix the problem that's fair for everyone.

13. Deciding what to eat

There's always a new diet or exercise that's popular. Don't just follow it because it's trendy. Find out if it's good for you. Ask someone who knows, like a doctor. Make choices that make you feel good and stay healthy.

14. Deciding what to do today

Everyone is busy with school, chores, and hobbies. Make a list of things you need to do. Decide which ones are most important. Plan your day so you can get things done and still have fun.

15. Making Tough Choices

Sometimes, it's hard to know what's right. Think about how each choice will affect you and others. Talk to people you trust about it. Choose what feels right in your heart and is fair to others.

16. Planning for the Future

Big decisions, like where to go to school, can be tricky. Think about what you want in the future. Look at the good and bad of each choice. Talk to people who know about it. Pick what feels best for your dreams and goals.

Job Examples

17. solving problems.

Workers brainstorm ways to fix a machine quickly without making things worse when a machine breaks at a factory.

18. Decision Making

A store manager decides which products to order more of based on what's selling best.

19. Setting Goals

A team leader helps their team decide what tasks are most important to finish this month and which can wait.

20. Evaluating Ideas

At a team meeting, everyone shares ideas for a new project. The group discusses each idea's pros and cons before picking one.

21. Handling Conflict

Two workers disagree on how to do a job. Instead of arguing, they talk calmly, listen to each other, and find a solution they both like.

22. Improving Processes

A cashier thinks of a faster way to ring up items so customers don't have to wait as long.

23. Asking Questions

Before starting a big task, an employee asks for clear instructions and checks if they have the necessary tools.

24. Checking Facts

Before presenting a report, someone double-checks all their information to make sure there are no mistakes.

25. Planning for the Future

A business owner thinks about what might happen in the next few years, like new competitors or changes in what customers want, and makes plans based on those thoughts.

26. Understanding Perspectives

A team is designing a new toy. They think about what kids and parents would both like instead of just what they think is fun.

School Examples

27. researching a topic.

For a history project, a student looks up different sources to understand an event from multiple viewpoints.

28. Debating an Issue

In a class discussion, students pick sides on a topic, like school uniforms, and share reasons to support their views.

29. Evaluating Sources

While writing an essay, a student checks if the information from a website is trustworthy or might be biased.

30. Problem Solving in Math

When stuck on a tricky math problem, a student tries different methods to find the answer instead of giving up.

31. Analyzing Literature

In English class, students discuss why a character in a book made certain choices and what those decisions reveal about them.

32. Testing a Hypothesis

For a science experiment, students guess what will happen and then conduct tests to see if they're right or wrong.

33. Giving Peer Feedback

After reading a classmate's essay, a student offers suggestions for improving it.

34. Questioning Assumptions

In a geography lesson, students consider why certain countries are called "developed" and what that label means.

35. Designing a Study

For a psychology project, students plan an experiment to understand how people's memories work and think of ways to ensure accurate results.

36. Interpreting Data

In a science class, students look at charts and graphs from a study, then discuss what the information tells them and if there are any patterns.

Critical Thinking Puzzles

Not all scenarios will have a single correct answer that can be figured out by thinking critically. Sometimes we have to think critically about ethical choices or moral behaviors. 

Here are some mind games and scenarios you can solve using critical thinking. You can see the solution(s) at the end of the post.

37. The Farmer, Fox, Chicken, and Grain Problem

A farmer is at a riverbank with a fox, a chicken, and a grain bag. He needs to get all three items across the river. However, his boat can only carry himself and one of the three items at a time. 

Here's the challenge:

• If the fox is left alone with the chicken, the fox will eat the chicken.
• If the chicken is left alone with the grain, the chicken will eat the grain.

How can the farmer get all three items across the river without any item being eaten? 

38. The Rope, Jar, and Pebbles Problem

You are in a room with two long ropes hanging from the ceiling. Each rope is just out of arm's reach from the other, so you can't hold onto one rope and reach the other simultaneously. 

Your task is to tie the two rope ends together, but you can't move the position where they hang from the ceiling.

You are given a jar full of pebbles. How do you complete the task?

39. The Two Guards Problem

Imagine there are two doors. One door leads to certain doom, and the other leads to freedom. You don't know which is which.

In front of each door stands a guard. One guard always tells the truth. The other guard always lies. You don't know which guard is which.

You can ask only one question to one of the guards. What question should you ask to find the door that leads to freedom?

40. The Hourglass Problem

You have two hourglasses. One measures 7 minutes when turned over, and the other measures 4 minutes. Using just these hourglasses, how can you time exactly 9 minutes?

41. The Lifeboat Dilemma

Imagine you're on a ship that's sinking. You get on a lifeboat, but it's already too full and might flip over. 

Nearby in the water, five people are struggling: a scientist close to finding a cure for a sickness, an old couple who've been together for a long time, a mom with three kids waiting at home, and a tired teenager who helped save others but is now in danger. 

You can only save one person without making the boat flip. Who would you choose?

42. The Tech Dilemma

You work at a tech company and help make a computer program to help small businesses. You're almost ready to share it with everyone, but you find out there might be a small chance it has a problem that could show users' private info. 

If you decide to fix it, you must wait two more months before sharing it. But your bosses want you to share it now. What would you do?

43. The History Mystery

Dr. Amelia is a history expert. She's studying where a group of people traveled long ago. She reads old letters and documents to learn about it. But she finds some letters that tell a different story than what most people believe. 

If she says this new story is true, it could change what people learn in school and what they think about history. What should she do?

The Role of Bias in Critical Thinking

Have you ever decided you don’t like someone before you even know them? Or maybe someone shared an idea with you that you immediately loved without even knowing all the details. 

This experience is called bias, which occurs when you like or dislike something or someone without a good reason or knowing why. It can also take shape in certain reactions to situations, like a habit or instinct. 

Bias comes from our own experiences, what friends or family tell us, or even things we are born believing. Sometimes, bias can help us stay safe, but other times it stops us from seeing the truth.

Not all bias is bad. Bias can be a mechanism for assessing our potential safety in a new situation. If we are biased to think that anything long, thin, and curled up is a snake, we might assume the rope is something to be afraid of before we know it is just a rope.

While bias might serve us in some situations (like jumping out of the way of an actual snake before we have time to process that we need to be jumping out of the way), it often harms our ability to think critically.

How Bias Gets in the Way of Good Thinking

Selective Perception: We only notice things that match our ideas and ignore the rest. 

It's like only picking red candies from a mixed bowl because you think they taste the best, but they taste the same as every other candy in the bowl. It could also be when we see all the signs that our partner is cheating on us but choose to ignore them because we are happy the way we are (or at least, we think we are).

Agreeing with Yourself: This is called “ confirmation bias ” when we only listen to ideas that match our own and seek, interpret, and remember information in a way that confirms what we already think we know or believe. 

An example is when someone wants to know if it is safe to vaccinate their children but already believes that vaccines are not safe, so they only look for information supporting the idea that vaccines are bad.

Thinking We Know It All: Similar to confirmation bias, this is called “overconfidence bias.” Sometimes we think our ideas are the best and don't listen to others. This can stop us from learning.

Have you ever met someone who you consider a “know it”? Probably, they have a lot of overconfidence bias because while they may know many things accurately, they can’t know everything. Still, if they act like they do, they show overconfidence bias.

There's a weird kind of bias similar to this called the Dunning Kruger Effect, and that is when someone is bad at what they do, but they believe and act like they are the best .

Following the Crowd: This is formally called “groupthink”. It's hard to speak up with a different idea if everyone agrees. But this can lead to mistakes.

An example of this we’ve all likely seen is the cool clique in primary school. There is usually one person that is the head of the group, the “coolest kid in school”, and everyone listens to them and does what they want, even if they don’t think it’s a good idea.

How to Overcome Biases

Here are a few ways to learn to think better, free from our biases (or at least aware of them!).

Know Your Biases: Realize that everyone has biases. If we know about them, we can think better.

Listen to Different People: Talking to different kinds of people can give us new ideas.

Ask Why: Always ask yourself why you believe something. Is it true, or is it just a bias?

Understand Others: Try to think about how others feel. It helps you see things in new ways.

Keep Learning: Always be curious and open to new information.

In today's world, everything changes fast, and there's so much information everywhere. This makes critical thinking super important. It helps us distinguish between what's real and what's made up. It also helps us make good choices. But thinking this way can be tough sometimes because of biases. These are like sneaky thoughts that can trick us. The good news is we can learn to see them and think better.

There are cool tools and ways we've talked about, like the "Socratic Questioning" method and the "Six Thinking Hats." These tools help us get better at thinking. These thinking skills can also help us in school, work, and everyday life.

We’ve also looked at specific scenarios where critical thinking would be helpful, such as deciding what diet to follow and checking facts.

Thinking isn't just a skill—it's a special talent we improve over time. Working on it lets us see things more clearly and understand the world better. So, keep practicing and asking questions! It'll make you a smarter thinker and help you see the world differently.

Critical Thinking Puzzles (Solutions)

The farmer, fox, chicken, and grain problem.

• The farmer first takes the chicken across the river and leaves it on the other side.
• He returns to the original side and takes the fox across the river.
• After leaving the fox on the other side, he returns the chicken to the starting side.
• He leaves the chicken on the starting side and takes the grain bag across the river.
• He leaves the grain with the fox on the other side and returns to get the chicken.
• The farmer takes the chicken across, and now all three items -- the fox, the chicken, and the grain -- are safely on the other side of the river.

The Rope, Jar, and Pebbles Problem

• Take one rope and tie the jar of pebbles to its end.
• Swing the rope with the jar in a pendulum motion.
• While the rope is swinging, grab the other rope and wait.
• As the swinging rope comes back within reach due to its pendulum motion, grab it.
• With both ropes within reach, untie the jar and tie the rope ends together.

The Two Guards Problem

The question is, "What would the other guard say is the door to doom?" Then choose the opposite door.

The Hourglass Problem

• Start both hourglasses. 
• When the 4-minute hourglass runs out, turn it over.
• When the 7-minute hourglass runs out, the 4-minute hourglass will have been running for 3 minutes. Turn the 7-minute hourglass over. 
• When the 4-minute hourglass runs out for the second time (a total of 8 minutes have passed), the 7-minute hourglass will run for 1 minute. Turn the 7-minute hourglass again for 1 minute to empty the hourglass (a total of 9 minutes passed).

The Boat and Weights Problem

Take the cat over first and leave it on the other side. Then, return and take the fish across next. When you get there, take the cat back with you. Leave the cat on the starting side and take the cat food across. Lastly, return to get the cat and bring it to the other side.

The Lifeboat Dilemma

There isn’t one correct answer to this problem. Here are some elements to consider:

• Moral Principles: What values guide your decision? Is it the potential greater good for humanity (the scientist)? What is the value of long-standing love and commitment (the elderly couple)? What is the future of young children who depend on their mothers? Or the selfless bravery of the teenager?
• Future Implications: Consider the future consequences of each choice. Saving the scientist might benefit millions in the future, but what moral message does it send about the value of individual lives?
• Emotional vs. Logical Thinking: While it's essential to engage empathy, it's also crucial not to let emotions cloud judgment entirely. For instance, while the teenager's bravery is commendable, does it make him more deserving of a spot on the boat than the others?
• Acknowledging Uncertainty: The scientist claims to be close to a significant breakthrough, but there's no certainty. How does this uncertainty factor into your decision?
• Personal Bias: Recognize and challenge any personal biases, such as biases towards age, profession, or familial status.

The Tech Dilemma

Again, there isn’t one correct answer to this problem. Here are some elements to consider:

• Evaluate the Risk: How severe is the potential vulnerability? Can it be easily exploited, or would it require significant expertise? Even if the circumstances are rare, what would be the consequences if the vulnerability were exploited?
• Stakeholder Considerations: Different stakeholders will have different priorities. Upper management might prioritize financial projections, the marketing team might be concerned about the product's reputation, and customers might prioritize the security of their data. How do you balance these competing interests?
• Short-Term vs. Long-Term Implications: While launching on time could meet immediate financial goals, consider the potential long-term damage to the company's reputation if the vulnerability is exploited. Would the short-term gains be worth the potential long-term costs?
• Ethical Implications : Beyond the financial and reputational aspects, there's an ethical dimension to consider. Is it right to release a product with a known vulnerability, even if the chances of it being exploited are low?
• Seek External Input: Consulting with cybersecurity experts outside your company might be beneficial. They could provide a more objective risk assessment and potential mitigation strategies.
• Communication: How will you communicate the decision, whatever it may be, both internally to your team and upper management and externally to your customers and potential users?

The History Mystery

Dr. Amelia should take the following steps:

• Verify the Letters: Before making any claims, she should check if the letters are actual and not fake. She can do this by seeing when and where they were written and if they match with other things from that time.
• Get a Second Opinion: It's always good to have someone else look at what you've found. Dr. Amelia could show the letters to other history experts and see their thoughts.
• Research More: Maybe there are more documents or letters out there that support this new story. Dr. Amelia should keep looking to see if she can find more evidence.
• Share the Findings: If Dr. Amelia believes the letters are true after all her checks, she should tell others. This can be through books, talks, or articles.
• Stay Open to Feedback: Some people might agree with Dr. Amelia, and others might not. She should listen to everyone and be ready to learn more or change her mind if new information arises.

Ultimately, Dr. Amelia's job is to find out the truth about history and share it. It's okay if this new truth differs from what people used to believe. History is about learning from the past, no matter the story.

What Is Critical Thinking? | Definition & Examples

Published on May 30, 2022 by Eoghan Ryan . Revised on May 31, 2023.

Critical thinking is the ability to effectively analyze information and form a judgment .

To think critically, you must be aware of your own biases and assumptions when encountering information, and apply consistent standards when evaluating sources .

Critical thinking skills help you to:

• Identify credible sources
• Evaluate and respond to arguments
• Assess alternative viewpoints
• Test hypotheses against relevant criteria

Table of contents

Why is critical thinking important, critical thinking examples, how to think critically, other interesting articles, frequently asked questions about critical thinking.

Critical thinking is important for making judgments about sources of information and forming your own arguments. It emphasizes a rational, objective, and self-aware approach that can help you to identify credible sources and strengthen your conclusions.

Critical thinking is important in all disciplines and throughout all stages of the research process . The types of evidence used in the sciences and in the humanities may differ, but critical thinking skills are relevant to both.

In academic writing , critical thinking can help you to determine whether a source:

• Is free from research bias
• Provides evidence to support its research findings
• Considers alternative viewpoints

Outside of academia, critical thinking goes hand in hand with information literacy to help you form opinions rationally and engage independently and critically with popular media.

Critical thinking can help you to identify reliable sources of information that you can cite in your research paper . It can also guide your own research methods and inform your own arguments.

Outside of academia, critical thinking can help you to be aware of both your own and others’ biases and assumptions.

Academic examples

However, when you compare the findings of the study with other current research, you determine that the results seem improbable. You analyze the paper again, consulting the sources it cites.

You notice that the research was funded by the pharmaceutical company that created the treatment. Because of this, you view its results skeptically and determine that more independent research is necessary to confirm or refute them. Example: Poor critical thinking in an academic context You’re researching a paper on the impact wireless technology has had on developing countries that previously did not have large-scale communications infrastructure. You read an article that seems to confirm your hypothesis: the impact is mainly positive. Rather than evaluating the research methodology, you accept the findings uncritically.

Nonacademic examples

However, you decide to compare this review article with consumer reviews on a different site. You find that these reviews are not as positive. Some customers have had problems installing the alarm, and some have noted that it activates for no apparent reason.

You revisit the original review article. You notice that the words “sponsored content” appear in small print under the article title. Based on this, you conclude that the review is advertising and is therefore not an unbiased source. Example: Poor critical thinking in a nonacademic context You support a candidate in an upcoming election. You visit an online news site affiliated with their political party and read an article that criticizes their opponent. The article claims that the opponent is inexperienced in politics. You accept this without evidence, because it fits your preconceptions about the opponent.

There is no single way to think critically. How you engage with information will depend on the type of source you’re using and the information you need.

However, you can engage with sources in a systematic and critical way by asking certain questions when you encounter information. Like the CRAAP test , these questions focus on the currency , relevance , authority , accuracy , and purpose of a source of information.

When encountering information, ask:

• Who is the author? Are they an expert in their field?
• What do they say? Is their argument clear? Can you summarize it?
• When did they say this? Is the source current?
• Where is the information published? Is it an academic article? Is it peer-reviewed ?
• Why did the author publish it? What is their motivation?
• How do they make their argument? Is it backed up by evidence? Does it rely on opinion, speculation, or appeals to emotion ? Do they address alternative arguments?

Critical thinking also involves being aware of your own biases, not only those of others. When you make an argument or draw your own conclusions, you can ask similar questions about your own writing:

• Am I only considering evidence that supports my preconceptions?
• Is my argument expressed clearly and backed up with credible sources?
• Would I be convinced by this argument coming from someone else?

Critical thinking refers to the ability to evaluate information and to be aware of biases or assumptions, including your own.

Like information literacy , it involves evaluating arguments, identifying and solving problems in an objective and systematic way, and clearly communicating your ideas.

Critical thinking skills include the ability to:

You can assess information and arguments critically by asking certain questions about the source. You can use the CRAAP test , focusing on the currency , relevance , authority , accuracy , and purpose of a source of information.

Ask questions such as:

• Who is the author? Are they an expert?
• How do they make their argument? Is it backed up by evidence?

A credible source should pass the CRAAP test  and follow these guidelines:

• The information should be up to date and current.
• The author and publication should be a trusted authority on the subject you are researching.
• The sources the author cited should be easy to find, clear, and unbiased.
• For a web source, the URL and layout should signify that it is trustworthy.

Information literacy refers to a broad range of skills, including the ability to find, evaluate, and use sources of information effectively.

Being information literate means that you:

• Know how to find credible sources
• Use relevant sources to inform your research
• Understand what constitutes plagiarism
• Know how to cite your sources correctly

Confirmation bias is the tendency to search, interpret, and recall information in a way that aligns with our pre-existing values, opinions, or beliefs. It refers to the ability to recollect information best when it amplifies what we already believe. Relatedly, we tend to forget information that contradicts our opinions.

Although selective recall is a component of confirmation bias, it should not be confused with recall bias.

On the other hand, recall bias refers to the differences in the ability between study participants to recall past events when self-reporting is used. This difference in accuracy or completeness of recollection is not related to beliefs or opinions. Rather, recall bias relates to other factors, such as the length of the recall period, age, and the characteristics of the disease under investigation.

Critical thinking refers to the ability to analyze information objectively and make a reasoned judgment. It involves the evaluation of sources, such as data, facts, observable phenomena, and research findings.

Good critical thinkers can draw reasonable conclusions from a set of information, and discriminate between useful and less useful details to solve problems or make decisions. Employers prioritize the ability to think critically—find out why, plus see how you can demonstrate that you have this ability throughout the job application process. 

Why Do Employers Value Critical Thinking Skills?

Employers want job candidates who can evaluate a situation using logical thought and offer the best solution.

 Someone with critical thinking skills can be trusted to make decisions independently, and will not need constant handholding.

Hiring a critical thinker means that micromanaging won't be required. Critical thinking abilities are among the most sought-after skills in almost every industry and workplace. You can demonstrate critical thinking by using related keywords in your resume and cover letter, and during your interview.

Examples of Critical Thinking

The circumstances that demand critical thinking vary from industry to industry. Some examples include:

• A triage nurse analyzes the cases at hand and decides the order by which the patients should be treated.
• A plumber evaluates the materials that would best suit a particular job.
• An attorney reviews evidence and devises a strategy to win a case or to decide whether to settle out of court.
• A manager analyzes customer feedback forms and uses this information to develop a customer service training session for employees.

Promote Your Skills in Your Job Search

If critical thinking is a key phrase in the job listings you are applying for, be sure to emphasize your critical thinking skills throughout your job search.

Add Keywords to Your Resume

You can use critical thinking keywords (analytical, problem solving, creativity, etc.) in your resume. When describing your  work history , include top critical thinking skills that accurately describe you. You can also include them in your  resume summary , if you have one.

For example, your summary might read, “Marketing Associate with five years of experience in project management. Skilled in conducting thorough market research and competitor analysis to assess market trends and client needs, and to develop appropriate acquisition tactics.”

Mention Skills in Your Cover Letter

Include these critical thinking skills in your cover letter. In the body of your letter, mention one or two of these skills, and give specific examples of times when you have demonstrated them at work. Think about times when you had to analyze or evaluate materials to solve a problem.

Show the Interviewer Your Skills

You can use these skill words in an interview. Discuss a time when you were faced with a particular problem or challenge at work and explain how you applied critical thinking to solve it.

Some interviewers will give you a hypothetical scenario or problem, and ask you to use critical thinking skills to solve it. In this case, explain your thought process thoroughly to the interviewer. He or she is typically more focused on how you arrive at your solution rather than the solution itself. The interviewer wants to see you analyze and evaluate (key parts of critical thinking) the given scenario or problem.

Of course, each job will require different skills and experiences, so make sure you read the job description carefully and focus on the skills listed by the employer.

Top Critical Thinking Skills

Keep these in-demand critical thinking skills in mind as you update your resume and write your cover letter. As you've seen, you can also emphasize them at other points throughout the application process, such as your interview. 

Part of critical thinking is the ability to carefully examine something, whether it is a problem, a set of data, or a text. People with  analytical skills  can examine information, understand what it means, and properly explain to others the implications of that information.

• Asking Thoughtful Questions
• Data Analysis
• Interpretation
• Questioning Evidence
• Recognizing Patterns

Communication

Often, you will need to share your conclusions with your employers or with a group of colleagues. You need to be able to  communicate with others  to share your ideas effectively. You might also need to engage in critical thinking in a group. In this case, you will need to work with others and communicate effectively to figure out solutions to complex problems.

• Active Listening
• Collaboration
• Explanation
• Interpersonal
• Presentation
• Verbal Communication
• Written Communication

Critical thinking often involves creativity and innovation. You might need to spot patterns in the information you are looking at or come up with a solution that no one else has thought of before. All of this involves a creative eye that can take a different approach from all other approaches.

• Flexibility
• Conceptualization
• Imagination
• Drawing Connections
• Synthesizing

Open-Mindedness

To think critically, you need to be able to put aside any assumptions or judgments and merely analyze the information you receive. You need to be objective, evaluating ideas without bias.

• Objectivity
• Observation

Problem Solving

Problem-solving is another critical thinking skill that involves analyzing a problem, generating and implementing a solution, and assessing the success of the plan. Employers don’t simply want employees who can think about information critically. They also need to be able to come up with practical solutions.

• Attention to Detail
• Clarification
• Decision Making
• Groundedness
• Identifying Patterns

More Critical Thinking Skills

• Inductive Reasoning
• Deductive Reasoning
• Noticing Outliers
• Adaptability

You Have No Excuse for Not Thinking Critically

Scrutinizing skullduggery, artifice, and malarkey is easier than ever..

Posted April 12, 2021 | Reviewed by Davia Sills

• A news story triggering your emotions is a red flag indicating that you need to think critically and investigate the story's veracity.
• Instead of letting other people think for you, do your own research and form your own opinions.
• Examine the motivation and any potential bias of the person(s) spreading the story, and look up facts using multiple sources.

A few years ago, I noticed a small growth on my eyelid. Over time, it continued to grow; it developed an odd shape that was dark in color and looked something like a cross between a mole and a wart.

I was concerned that it might be skin cancer, so I went to see my dermatologist. After examining it, she told me that it was not cancer. That was a relief, but then she added that while it was benign, it was in a location that she could not treat. She said that it would continue to grow and that at some point, I would need to have an eye surgeon remove it. Ugh!

After several months of watching it grow, I decided to do an online search for natural methods to remove skin growth. I found a woman who said she was able to remove skin tags and moles from her face by soaking cotton balls in apple cider vinegar, then taping them over the growths and leaving them in place for several hours. Clearly, I couldn’t tape a soggy cotton ball full of vinegar over my eye, so that was out.

After giving it some thought, I decided to try something similar. I dipped a Q-tip cotton swab in apple cider vinegar and then used it to carefully paint the vinegar over the growth on my eyelid. I couldn’t get the swab too wet, or the vinegar would get in my eye and burn. I did this twice a day for about a month, then decided nothing was happening and that I was wasting my time. So I quit.

Then, about two weeks later, I noticed that the growth had gotten even darker and was now hard and crusty to the touch. My first thought was that it was getting worse, but a few days later, to my surprise, the whole thing fell off; there was nothing but fresh, clean skin where the growth had been.

Lesson Learned: there may be an alternative solution to your problem than the one you know.

Useful knowledge is at your fingertips.

One summer, I went to pressure wash my patio, but my pressure washer wasn’t working. I called a repair shop, and the owner quoted me a price to fix it that was nearly the same as the cost of a new one. I then went onto YouTube and looked up small engine repairs. After a few minutes, I found one that resolved my problem, and I was able to fix my pressure washer for $7.

The world is at our fingertips if we only look. On the internet, I’ve learned how to tune my bicycle, diagnose problems with my car, and much more. You can even learn how to play the piano! Pretty much anything you want to know, you can begin learning from information online. Including finding out whether or not someone is telling you the truth.

Bad players take advantage of your ignorance.

We’ve all gotten an email from a Nigerian prince who wants to give us millions of dollars, or heard an extraordinary argument from a flat-earther, or gotten a scam phone call from someone claiming to be from the IRS, Social Security, or Microsoft. It seems that we are being lied to all the time—even from sources we used to trust! These days, you need to question a purveyor of information’s motivation to discover their bias or agenda.

We’ve all heard about "fake news ," but how do you know if what you’ve heard is false? One way is to evaluate the story for rhetorical fallacies and propaganda techniques (see my previous articles: "Protect Yourself From Verbal Sleight of Hand" and "Propaganda ‘til You Puke" ).

Watch out for these red flags.

The easiest way to suspect the veracity of a story is if it triggers you emotionally. Does the story make you feel angry, afraid , anxious , depressed , ecstatic, or excited? If so, then you should consider your inflamed emotion to be a red flag for potential fake news .

When your emotions are impacted by a story, it probably needs further investigation to determine the truth. If you feel particularly emotional, it could mean that you are being manipulated. This is especially likely if the story treads on any societal taboo topics, such as sex , religion, or politics .

Is there a "wow factor" to the story? If it makes you think, “Wow, that’s incredible!” or “That’s unbelievable!” then it probably is.

Another red flag is if you feel like you are being pressured or pushed into doing something that makes you feel uncomfortable or that you don’t want to do. What is the motivation behind the person or organization pressuring you? Is there a money trail ?

Are you only hearing one side of a story ? Is there another side? Do the research and find out.

For example, in war, the victors get to write the history books, or at least spin the facts in their favor. I have a friend who, in the days before the internet, used a short-wave radio receiver to listen to news from other countries in order to get more balanced information. Today you can get news from all over the world easily on your computer.

Consider it a red flag if you feel you are not allowed to question something or that you will be ostracized or penalized for questioning it. Be wary of topics that you are not allowed to question.

I had an employer who told me I wasn’t allowed to discuss my salary with other employees. Of course not: I might have found out I was being paid less and ask for a raise. When subjects are not allowed to be discussed, the truth cannot be discovered... and perhaps that is the point.

Choices and alternatives constitute freedom.

Is someone making you believe you do not have a choice? You always have a choice—there are always alternatives—just like I discovered with the treatment for the growth on my eyelid.

The internet has made the ability to examine and analyze issues available to everyone. We all have access to the same information if we only bother to explore. Learn to question authority and challenge the status quo . Ask questions like: “Why does it have to be this way?”; "Is there a substitute?"; “Can we try something different?”

Fake news begets fake fact-checkers.

Sadly, because of their political leaning, you can’t trust online fact-checkers to do your critical thinking for you. Fact-checkers don’t operate for free, which means most of them are financially supported by members of partisan factions. Those factions have agendas that influence the fact-checkers' objectivity and destroy their credibility.

Research the financial backers of the various fact-checkers. Some will be non-profit organizations, which means you’ll have to dig and hunt for who is financing those as well. Most of us don’t have time to probe that deep; it’s easier just to assume that all of them are biased.

Seek alternative sources for information online.

Don’t use just one search engine on the internet. Some of the biggest search engines have been caught suppressing information in an effort to shape public opinion. Use several search engines to do your investigations.

If you are getting your news from social media , you need to know that social media sites also suppress stories. Subscribe to several social media sites in order to get a variety of news and opinion.

Ignorance is not bliss.

"I freed a thousand slaves. I could have freed a thousand more if only they knew they were slaves," is a quote attributed (and perhaps incorrectly) to Harriet Tubman. Whether she said it or not, it still serves as an apt aphorism for many people in today’s world: If you don’t know you’re oppressed, then you can’t be liberated.

Today, there is no reason to be uninformed anymore. Become a critical thinking investigator today, and liberate yourself from fake news , propaganda, indoctrination, and scams. You’ll be happy you did.

Pursuing Truth: A Guide to Critical Thinking

Chapter 3 categorical logic.

Now we turn to some structured logic systems. The first, categorical logic, is one of the oldest. It dates back at least to Aristotle (384–322 BCE). Categorical logic is a fairly simple logic of categories or classes. A class is a group of things that we designate with a common noun: students, teachers, dogs, politicians, etc. Each sentence will use two different classes. One is the subject class, and the other is the predicate class. In this logic, we can say something about all members of a class, called a universal sentence, or we can say something about some members of a class, called a particular sentence. We can also make a positive claim, called an affirmation, or we can make a negative claim, called a negation.

With these two distinctions, universal/particular and affirnation/negation, we can make four kinds of sentences. S and P stand for the subject class and the predicate class, respectively.

Here are some examples of categorical statements, some true and some false.

• All dogs are mammals.
• All mammals are dogs.
• No reptiles are dogs.
• No politicians are honest people.
• Some politicians are honest people.
• Some cats are amphibians.
• Some dogs are not beagles.
• Some beagles are not dogs.

Look at the sentences carefully. You should be able to tell that the odd-numbered ones are true and the even-numbered ones are false.

3.1 The Square of Opposition

We can visualize interesting logical relationships between these four types of sentences with something called “The Square of Opposition.”

The first step is to place the sentence types in the corners of an imaginary square. A is at the upper left; E, the upper right; I, the lower left, and O, the lower right. Next, draw arrows on the diagonals, pointing to the sentences in the corners. Then, draw an arrow between the two at the top, and another one between the two at the bottom. Finally, draw an arrow on each side, going from top to bottom. When finished, you should have something like this:

Figure 3.1: Square of Opposition

The next step is to note the relationship between the diagonals. The diagonals are contradictories, meaning they always have opposite truth values. They can’t both be true, and they also can’t both be false. If the A sentence is true, the O sentence must be false—if it is true that all dogs are mammals, it cannot be true that some dogs are not mammals. If the O sentence is true, then the A sentence must be false. It is the same for the E and the I.

Next, note the relationship between the A sentences and the E sentences, called contraries. Like the contradictories, they cannot both be true. Unlike the contradictories, they can both be false. If it’s true that all critical thinking students are good students, then it must be false that no critical thinking students are good students. If it’s false that all critical thinking students are good students, then it can be false that critical thinking students are good students. In fact, they are both false, because some critical thinking students are good and others are not.

At the bottom, we have sub-contraries. They can both be false, but cannot both be true.

Finally, we have the relationship between the top level sentences and the bottom level sentences on the same side. This is called alternation. The universal is called the superaltern and the particular is called the subaltern. If the superaltern is true, then the subaltern must also be true. If the superaltern is false, then the subaltern can be either true or false. If the subaltern is false, then the superaltern must be false. If the subaltern is true, then the superaltern can be either true or false. It is easy to remember this way: truth goes down, falsity goes up.

3.2 Diagramming Sentences

We diagram sentences and arguments in categorical logic using Venn diagrams. You’ve probably used these in a math class at some time. Before we can use these to evaluate arguments in categorical logic, we first have to learn how to diagram individual sentences.

The first step is to draw two interlocking circles. Label the left circle with an “S” and the right circle with “P”—standing for the subject term and predicate term, respectively.

Figure 3.2: Starting a venn diagram

3.2.1 A-Sentences

Remember that the A-sentence has the form All S are P. That means that everything that is in the S circle must also be in the P circle. To diagram this, we shade the region of the S circle that is not contained in the P circle. If a region is shaded, that means that nothing is in that region.

Figure 3.3: Diagramming an A-Sentence

3.2.2 E-Sentences

To shade the universal negation, we shade the region that is shared by both S and P:

Figure 3.4: Diagramming an E-Sentence

3.2.3 I-Sentences

To diagram a particular affirmation, we place an x in the region shared by S and P:

Figure 3.5: Diagramming an I-Sentence

3.2.4 O-Sentences

Finally, to diagram an O-sentence, we place an x in S, but not in P:

Figure 3.6: Diagramming an O-Sentence

3.3 Evaluating Categorical Syllogisms

A syllogism is an argument that has two premises and a conclusion. A categorical syllogism is a syllogism that contains only categorical sentences. Here is an example:

• All Dogs are mammals.
• All mammals are animals.
• All dogs are animals

Both premises and the conclusion are A-sentences. Notice that we have three terms in the argument: dogs, mammals, and animals. Every categorical syllogism, in proper form, has three terms. Each term occurs in two sentences. Two of those terms will be found in the conclusion, and one term is only in the premises. The predicate term of the conclusion is called the major term. The subject of the conclusion is called the minor term. The term that is not in the conclusion is called the middle term.

There are two ways to determine if a categorical syllogism is valid. One way uses Venn diagrams, and the other involves applying some simple rules.

3.3.1 Diagram Method

Since we have three terms in the argument, we’ll need three intersecting circles. We’ll start by drawing two circles for the conclusion, just as we did before. Then, in the middle and below, we’ll draw another circle for the middle term. For labels, use letters that correspond to the classes in the argument. Here, we’ll use D for dogs, M for mammals, and A for animals.

Figure 3.7: Diagramming a categorical syllogism, step 1

Next, we finish diagramming the premises by shading or placing an x. Since our first premise is ``All dogs are mammals,’’ we need to shade everything in the D circle that is not in the M circle.

Figure 3.8: Diagramming a categorical syllogism, step 2

Next, we diagram the second premise by shading everything that is in the M circle but not in the A circle.

Figure 3.9: Diagramming a categorical syllogism, step 3

If there is any circle that has only one region left unshaded, you can place an `X’ in that region. This is because categorical logic assumes that there are no empty categories, meaning that every category has at least one thing in it. This is really only important for arguments that have an I or an O-sentence for a conclusion. In this case, we won’t worry about it. Now that the premises are diagrammed, check to see if the conclusion has also been diagrammed. If so, then the argument is valid. This shows that making the premises true was enough to make the conclusion true also.

Let’s try to diagram this argument:

• No introverts are politicians
• All artists are introverts
• No artists are politicians

Figure 3.10: Celarent

• Some horses are things that weigh over 2,000 pounds.
• All horses are mammals.
• Some mammals are things that weigh over 2,000 pounds.

Figure 3.11: Disamis

3.3.2 Hints for Diagramming Categorical Syllogisms

• Diagram universals before particulars (shade before making an x.)
• If it is not clear where the x goes, then put it on the line.

3.4 Rules for Categorical Syllogisms

There is another way to determine validity for categorical syllogisms. Every valid syllogism must meet three conditions:

• There must be the same number of negations in the conclusion as in the premises.
• The middle term must be distributed at least once.
• Any term distributed in the conclusion must be distributed in the premises.

Before these rules can be applied, we’ll have to explain what distribution is. Every categorical statement says something about a category or class. A statement distributes a term just in case what it says about that class is true of every subset of the class. To remember when something is distributed, keep this in mind:

• Universals distribute subjects, and
• Negations distribute predicates.

So, A-sentences distribute the subject, E-sentences distribute both terms, I-sentences don’t distribute anything, and O sentences distribute the predicate.

3.5 Relations of Equivalence

Properly formed categorical syllogisms have only three terms. Unfortunately, some arguments that you will encounter won’t always be in proper form. One common way this happens is for a person to use a term like “Americans” in one premise, but use “non-Americans” in another. This can result in a syllogism with four or more terms, making it impossible to evaluate using either of our two methods. What we then need to do is to convert the sentence using one of the terms into a logically equivalent sentence that uses the other term.

There are three operations that can be applied to categorical sentences: conversion, obversion, and contraposition. It is important to know both how to apply them and in what cases does an operation result in an equivalent sentence. We’re particularly interested in the conditions that those different operations are truth-preserving . An operation is truth preserving when, applied to a true sentence, it always results in a true sentence.

3.5.1 Conversion

Conversion is the simplest of the three. The converse of a sentence simply exchanges the subject and predicate terms of the original sentence. Conversion applied to A-sentences is truth-preserving. “All dogs are mammals” is true, but “All mammals are dogs” is not. Conversion is truth-preserving for E-sentences and I-sentences. If it is true that no dogs are reptiles, it must be true that no reptiles are dots. Likewise, if it is true that some dogs are brown things, it must be true that some brown things are dogs.

3.5.2 Obversion

Take another look at the square of opposition in figure 4.1. Note that the A and the E are straight across from each other, as are the I and the O. The first step in forming the obverse is to first change the sentence into the type that is straight across the square of opposition. That is, if you started with an A-sentence, then make it into and E. The O becomes and I, and so on.

Once you’ve changed the sentence type, the next step is to change predicate into its complement. The complement of a class C is the class of everything that is not in C . The easiest way to form a complement is to prefix the class with `non’. For example, the complement of the class of students is the class of non-students.

So, the obverse of all dogs are mammals is no dogs are non-mammals. The obverse of no OBU students are martians is all OBU students are non-martians. Obversion is truth-preserving in all cases.

3.5.3 Contraposition

The last of our three relations is contraposition. To form the contrapositive of a sentence, first form the converse, then exchange both terms for their complements.

The contrapositive of all dogs are mammals is all non-mammals are non-dogs. Contraposition is truth-preserving for A-sentences and O-sentences only.

Here’s a table to help keep this straight (operations that are truth-preserving are in bold type):

3.5.4 Example

• All Catholics are non-Protestants.
• All Lutherans are Protestants.
• No Catholics are Lutherans.

Note that this argument has four terms:

• Non-Protestants
• Protestants

To evaluate the argument, we will first have to either change “non-Protestants” to “Protestants” in the first premise, or “Protestants” to “non-Protestants” in the second premise and conclusion. To minimize errors, we should probably try the option requiring the fewest changes. The only two truth-preserving operations on A-sentences are obversion and contraposition. The contrapositive of “All Catholics are non-Protestants” is “All non-non-Protestants are non-Catholics.” The double-non will cancel out, which will fix our original problem, but it will leave us with a new term, “non-Catholic.” So, let’s try the obverse. The obverse of “All Catholics are non-Protestants” is “No Catholics are Protestants.” So, using that for our first premise, the argument becomes:

• No Catholics are Protestants.

Now, we can check for validity — I’ll leave that for you.

The letters A, E, I, and O, are thought to come from the first two vowels of the Latin words affirmo and nego , meaning “I affirm” and “I deny.” ↩︎

25 Critical Thinking Examples

Critical thinking is the ability to analyze information and make reasoned decisions. It involves suspended judgment, open-mindedness, and clarity of thought.

It involves considering different viewpoints and weighing evidence carefully. It is essential for solving complex problems and making good decisions.

People who think critically are able to see the world in a more nuanced way and understand the interconnectedness of things. They are also better able to adapt to change and handle uncertainty.

In today’s fast-paced world, the ability to think critically is more important than ever and necessary for students and employees alike.

Critical Thinking Examples

1. identifying strengths and weaknesses.

Critical thinkers don’t just take things at face value. They stand back and contemplate the potential strengths and weaknesses of something and then make a decision after contemplation.

This helps you to avoid excessive bias and identify possible problems ahead of time.

For example, a boxer about to get in the ring will likely need to evaluate the strengths and weaknesses of his opponent. He might learn that his opponent’s left hook is very strong, but his opponent also gets tired after the third round. With this knowledge, he can go into the bout with strong defenses in the first three rounds before going on the offense.

Here, the boxer’s critical thinking skills will help him win his match.

2. Creating a Hypothesis based on Limited Data

When scientists set out to test a new theory, they first need to develop a hypothesis. This is an educated guess about how things work, based on what is already known.

Once a hypothesis has been developed, experiments can be designed to test it.

However, sometimes scientists may find themselves working with limited data. In such cases, they may need to make some assumptions in order to form a hypothesis.

For example, if they are studying a phenomenon that occurs infrequently, they may need to extrapolate from the data they do have in order to form a hypothesis.

Here, the scientist is engaged in critical thinking: they use the limited data to come up with a tentative judgment.

3. Moderating a Debate

A debate moderator needs to have strong critical thinking skills. They need to use objective evaluations, analysis, and critique to keep the discussion on track and ensure that all sides are heard fairly.

This means being able to identify when a point has been made sufficiently, or when someone is beginning to veer off topic and being able to direct the conversation accordingly.

Similarly, they need to be able to assess each argument objectively and consider its merits, rather than getting caught up in the emotion of the debate. If someone is using an unfair point or one that is not factual, the moderator needs to be switched on and identify this.

By remaining calm and impartial, the moderator can help to ensure that a debate is productive and respectful.

4. Judging and Adjudicating

A judge or adjudicator needs to weigh the evidence and make a determination based on the facts.

This requires the adjudicator to be able to try to see both sides of an argument. They need the ability to see past personal biases and to critically evaluate the credibility of all sides.

In addition, judges and adjudicators must be able to think quickly and make sound decisions in the face of complex issues.

For example, if you were to be adjudicating the above debate, you need to hear both sides of the argument and then decide who won. It’s your job to evaluate, see strengths and weaknesses in arguments, and come to a conclusion.

5. Grading an Essay

Teachers need critical thinking skills when grading essays so that they can effectively assess the quality of the writing. By critically analyzing the essay, teachers can identify any errors or weaknesses in the argument.

Furthermore, they can also determine whether the essay meets the required standards for the assignment. Even a very well-written essay may deserve a lower grade if the essay doesn’t directly answer the essay question.

A teacher needs to be able to read an essay and understand not only what the student is trying to say, but also how well they are making their argument. Are they using evidence effectively? Are they drawing valid conclusions? A teacher needs to be able to evaluate an essay holistically in order to give a fair grade.

In order to properly evaluate an essay, teachers need to be able to think critically about the writing. Only then can they provide an accurate assessment of the work.

6. Active Reading

Active reading is a skill that requires the reader to be engaged with the text in order to fully understand it. This means not only being able to read the words on the page, but also being able to interpret the meaning behind them.

In order to do this, active readers need to have good critical thinking skills.

They need to be able to ask questions about the text and look for evidence to support their answers. Additionally, active readers need to be able to make connections between the text and their own experiences.

Active reading leads to better comprehension and retention of information.

7. Deciding Whether or Not to Believe Something

When trying to determine whether or not to believe something, you’re engaging in critical thinking.

For example, you might need to consider the source of the information. If the information comes from a reliable source, such as a reputable news organization or a trusted friend, then it is more likely to be accurate.

However, if the source is less reliable, such as an anonymous website or a person with a known bias, then the information should be viewed with more skepticism.

In addition, it is important to consider the evidence that is being presented. If the evidence is well-supported and logically presented, then it is more likely to be true. However, if the evidence is weak or relies on fallacious reasoning, then the claim is less likely to be true.

8. Determining the Best Solution to a Situation

Determining the best solution to a problem generally requires you to critique the different options. There are often many different factors to consider, and it can be difficult to know where to start.

However, there are some general guidelines that can help to make the process a little easier.

For example, if you have a few possible solutions to the problem, it is important to weigh the pros and cons of each one. Consider both the short-term and long-term effects of each option before making a decision.

Furthermore, it is important to be aware of your own biases. Be sure to consider all of the options objectively, without letting your personal preferences get in the way.

9. Giving Formative Feedback

Formative feedback is feedback that you give to someone part-way through a learning experience. To do this, you need to think critically.

For example, one thing you need to do is see where the student’s strengths and weaknesses like. Perhaps the student is doing extremely well at a task, so your feedback might be that they should try to extend themselves by adding more complexity to the task.

Or, perhaps the student is struggling, so you suggest to them that they approach the learning experience from a different angle.

10. Giving Summative Feedback

Summative feedback occurs at the end of a learning scenario. For example, the written feedback at the end of an essay or on a report card is summative.

When providing summative feedback, it is important to take a step back and consider the situation from multiple perspectives. What are areas for improvement and where exactly might the student have missed some key points? How could the student have done better?

Asking yourself these questions is all part of the process of giving feedback, and they can all be considered examples of critical thinking. You’re literally critiquing the student’s work and identifying opportunities for improvement.

11. Evaluating Evidence

When evaluating evidence, critical thinkers take a step back and look at the bigger picture. They consider all of the available information and weigh it up. They look at logical flaws, the reliability of the evidence, and its validity.

This process allows them to arrive at a conclusion that is based on sound reasoning, rather than emotion or personal bias.

For example, when a social scientist looks at the evidence from his study, he needs to evaluate whether the data was corrupted and ensure the methodology was sound in order to determine if the evidence is valuable or not.

12. Media Literacy

Media literacy seems to be in short supply these days. Too many people take information off the internet or television and just assume it is true.

A person with media literacy, however, will not just trust what they see and read. Instead, they look at the data and weigh up the evidence. They will see if there was a sound study to back up claims. They will see if there is bias in the media source and whether it’s just following an ideological line.

Furthermore, they will make sure they seek out trustworthy media sources. These are not just media sources you like or that confirm your own point of view. They need to be sources that do their own research, find solid data, and don’t pursue one blind agenda.

13. Asking your Own Questions

Asking your own questions is an important part of critical thinking. When you ask questions, you are forcing yourself to think more deeply about the information you are considering.

Asking questions also allows you to gather more information from others who may have different perspectives.

This helps you to better understand the issue and to come up with your own conclusions.

So, often at schools, we give students a list of questions to ask about something in order to dig deeper into it. For example, in a book review lesson, the teacher might give a list of questions to ask about the book’s characters and plot.

14. Conducting Rigorous Research

Research is a process of inquiry that encompasses the gathering of data, interpretation of findings, and communication of results. The researcher needs to engage in critical thinking throughout the process, but most importantly, when designing their methodology.

Research can be done through a variety of methods, such as experiments, surveys, interviews, and observations. Each method has strengths and weaknesses.

Once the data has been collected, it must be analyzed and interpreted. This is often done through statistical methods or qualitative analysis.

Research is an essential tool for discovering new knowledge and for solving problems, but researchers need to think critically about how valid and reliable their data truly is.

15. Examining your own Beliefs and Prejudices

It’s important to examine your own beliefs and prejudices in order to ensure that they are fair and accurate. People who don’t examine their own beliefs have not truly critically examined their lives.

One way to do this is to take the time to consider why you believe what you do. What experiences have you had that have led you to this belief? Are there other ways to interpret these experiences? It’s also important to be aware of the potential for confirmation bias , which is when we seek out information that confirms our existing beliefs, while ignoring information that contradicts them.

This can lead us to hold onto inaccurate or unfair beliefs even when presented with evidence to the contrary.

To avoid this, it’s important to seek out diverse perspectives, and to be open-minded when considering new information. By taking these steps, you can help ensure that your beliefs are fair and accurate.

16. Looking at a Situation from Multiple Perspectives

One of the most important critical thinking skills that you can learn in life is how to look at a situation from multiple perspectives.

Being able to see things from different angles can help you to understand complex issues, spot potential problems, and find creative solutions. It can also help you to build better relationships, as you will be able to see where others are coming from and find common ground.

There are a few simple techniques that you can use to develop this skill.

First, try to imagine how someone else would feel in the same situation.

Second, put yourself in their shoes and try to see things from their point of view.

Finally, ask yourself what other factors may be influencing their perspective. By taking the time to view things from multiple angles, you will be better prepared to deal with whatever life throws your way.

17. Considering Implications before Taking Action

When faced with a difficult decision, it is important to consider the implications of each possible action before settling on a course of action.

This is because the consequences of our actions can be far-reaching and often unforeseen.

For example, a seemingly small decision like whether to attend a party or not might have much larger implications. If we decide to go to the party, we might miss an important deadline at work.

However, if we stay home, we might miss out on an opportunity to meet new people and make valuable connections.

In either case, our choice can have a significant impact on our lives.

Fortunately, critical thinking can help people to make well-informed decisions that could have a positive impact on their lives.

For example, you might have to weight up the pros and cons of attending the party and identify potential downsides, like whether you might be in a car with an impaired driver, and whether the party is really worth losing your job.

Having weighed up the potential outcomes, you can make a more rational and informed decision.

18. Reflective Practice

Reflecting on your actions is an important part of critical thinking. When you take the time to reflect, you are able to step back and examine your choices and their consequences more objectively.

This allows you to learn from your mistakes and make better decisions in the future.

In order to reflect effectively, it is important to be honest with yourself and open to learning new things. You must also be willing to question your own beliefs and assumptions. By taking these steps, you can develop the critical thinking skills that are essential for making sound decisions next time.

This will also, fortunately, help you to constantly improve upon yourself.

19. Problem-Solving

Problem-solving requires the ability to think critically in order to accurately assess a situation and determine the best course of action.

This means being able to identify the root cause of a problem , as well as any potential obstacles that may stand in the way of a solution. It also involves breaking down a problem into smaller, more manageable pieces in order to more easily find a workable solution.

In addition, critical thinking skills also require the ability to think creatively in order to come up with original solutions to these problems.

Go Deeper: Problem-Solving Examples

20. Brainstorming New Solutions

When brainstorming new solutions , critical thinking skills are essential in order to generate fresh ideas and identify potential issues.

For example, the ability to identify the problems with the last solution you tried is important in order to come up with better solutions this time. Similarly, analytical thinking is necessary in order to evaluate the feasibility of each idea. Furthermore, it is also necessary to consider different perspectives and adapt to changing circumstances.

By utilizing all of these critical thinking skills, it will be possible to develop innovative solutions that are both practical and effective.

21. Reserving Judgment

A key part of critical thinking is reserving judgment. This means that we should not rush to conclusions, but instead take the time to consider all the evidence before making up our minds.

By reserving judgment, we can avoid making premature decisions that we might later regret. We can also avoid falling victim to confirmation bias, which is the tendency to only pay attention to information that supports our existing beliefs.

Instead, by keeping an open mind and considering all the evidence, we can make better decisions and reach more accurate conclusions.

22. Identifying Deceit

Critical thinking is an important skill to have in any situation, but it is especially important when trying to identify deceit.

There are a few key things to look for when using critical thinking to identify deceit.

First, pay attention to the person’s body language. Second, listen closely to what the person is saying and look for any inconsistencies. Finally, try to get a sense of the person’s motive – why would they want to deceive you?

Each of these questions helps you to not just take things at their face value. Instead, you’re critiquing the situation and coming to a conclusion using all of your intellect and senses, rather than just believing what you’re told.

23. Being Open-Minded to New Evidence that Contradicts your Beliefs

People with critical thinking skills are more open-minded because they are willing to consider different points of view and evidence.

They also realize that their own beliefs may be wrong and are willing to change their minds if new information is presented.

Similarly, people who are not critical thinkers tend to be close-minded because they fail to critique themselves and challenge their own mindset. This can lead to conflicts, as closed-minded people are not willing to budge on their beliefs even when presented with contradictory evidence.

Critical thinkers, on the other hand, are able to have more productive conversations as they are willing to listen to others and consider different viewpoints. Ultimately, being open-minded and willing to change one’s mind is a sign of intelligence and maturity.

24. Accounting for Bias

We all have biases, based on our individual experiences, perspectives, and beliefs. These can lead us to see the world in a certain way and to interpret information in a way that supports our existing views.

However, if we want to truly understand an issue, it is important to try to put aside our personal biases and look at the evidence objectively.

This is where critical thinking skills come in.

By using critical thinking, we can examine the evidence dispassionately and assess different arguments without letting our own prejudices get in the way. Start by looking at weaknesses and logical flaws in your own thinking.

Play the devil’s advocate.

In this way, you can start to get a more accurate picture of an issue and make more informed decisions.

25. Basing your Beliefs on Logic and Reasoning

In order to lead a successful and fulfilling life, it is important to base your beliefs on logic and reasoning.

This does not mean that you should never believe in something without evidence, but it does mean that you should be thoughtful and intentional about the things that you choose to believe.

One way to ensure that your beliefs are based on logic and reasoning is to seek out reliable sources of information. Another method is to use thought games to follow all your thoughts to their logical conclusions.

By basing your beliefs on logic and reasoning, you will be more likely to make sound decisions, and less likely to be swayed by emotions or misinformation.

Critical thinking is an important skill for anyone who wants to be successful in the modern world. It allows us to evaluate information and make reasoned decisions, rather than simply accepting things at face value. 

Thus, employers often want to employ people with strong critical thinking skills. These employees will be able to solve problems by themselves and identify ways to improve the workplace. They will be able to push back against bad decisions and use their own minds to make good decisions.

Furthermore, critical thinking skills are important for students. This is because they need to be able to evaluate information and think through problems with a critical mindset in order to learn and improve.

Critical thinking is the ability to analyze and evaluate information logically and unbiasedly. It is a skill that can help us make better decisions, solve problems, and avoid fallacies. However, not everyone has good critical thinking skills, and some people may even have bad critical thinking habits that hinder their reasoning. But your Life may full of opportunities and challenges. You can choose to focus on the positive aspects of your life and appreciate what you have. Rather than being a poor reasoner.

Sanju Pradeepa

Thinking critically is essential for success in life, yet it’s not always easy. That’s why so many of us fall back on less effective thinking patterns. But what exactly are these poor critical thinking examples?

In this article, we’ll outline some of the most common examples of poor critical thinking and explain why they don’t hold up to rigorous scrutiny. We’ll also share an actionable approach to help you start thinking more critically and be more successful in your daily life.

So, whether you’re struggling with the idea of critical thinking or have already embraced the concept, read on to find what are bad critical thinking examples, learn some useful tips and insights that can help you become a better thinker.

What is critical thinking.

Critical thinking is the process of actively and skillfully gathering, evaluating, and discussing information to reach an informed decision or conclusion. It involves analyzing evidence, addressing different perspectives, making connections between ideas, and creating arguments and conclusions.

However, there are some common pitfalls to critical thinking that can prevent you from arriving at the best conclusions.

For example, using overly simplistic solutions to complex problems, such as basing decisions solely on emotions rather than facts and logical reasoning, making assumptions without considering the evidence, or not questioning your own biases,

Ultimately, poor critical thinking skills can lead to rushed decisions that do not fully consider all of the available information or evidence.

As a result, it is important to practice critical thinking regularly to develop strong analytical skills that are necessary for any decision-making process.

Bad Critical Thinking Examples

These examples highlight just how easy it is to get caught up in our own biases rather than relying on facts and data to reach conclusions. So, if you want to practice better critical thinking skills, try to identify these traps before they ensnare your reasoning skills.

1. Substituting Emotion for Reason

Have you ever found yourself substituting emotion for reason? It’s a common mistake. But what does that mean exactly?

It is when you make important decisions based purely on your feelings, rather than on facts and logic. Your emotions may tell you something’s wrong, but if you don’t use facts to back up your feelings, chances are you’re making an ill-informed decision.

One example of substituting emotion for reason is forming an opinion about someone else’s choices without considering their point of view. In this situation, you may have a strongly held belief about how certain scenarios “should” turn out, but if you don’t consider the other person’s reason for making their decision, you could be missing key information.

This might look like deciding something before considering all of the evidence or relying on assumptions instead of facts.

Tip – The best way to avoid substituting emotion for reason is to take a step back and ask yourself, “Am I looking at the whole picture?” If not, use critical thinking skills like fact-checking or asking questions to gain a more complete understanding of the situation.

With an open mind and an objective approach, it’s possible to make decisions based on facts instead of feelings.

2. Jumping to Conclusions Without Evaluating Evidence

It’s easy to come to a conclusion based on assumptions rather than facts and reasoning.

Let’s say someone told you that Bob always arrives late for work. Without looking into the evidence, you might assume he’s lazy and not a team player. But after looking at the evidence, for example, if Bob was in a car accident or his commute was particularly long that week, you’d realize there were other factors at play here.

So what can we learn from this? Well, it comes down to seeing things from multiple perspectives and understanding there may be more than one explanation for something. Before concluding,

Tip – It’s important to evaluate the evidence surrounding it and consider all possible factors influencing the situation. This way, you can get closer to the truth rather than making assumptions based on an incomplete picture.

3. Ignoring Information and Facts

You might not know this, but one of the most common examples is ignoring information and facts. It’s like you have blinders on and you’re determined to stick to your own opinion no matter what, even though there is evidence that contradicts it.

Ignoring important information and facts is bad news because facts are the foundation of critical thinking. If you don’t consider relevant data when reaching a conclusion, then you can’t have an accurate opinion; it will just be based on assumptions and your own biases. 

Tip – So, here are some things to look out for when it comes to avoiding this mistake:

• Don’t dismiss facts that are presented by people who present them in an unfamiliar way, even if the information seems overwhelming or confusing at first glance.
• Consider all angles of a situation before making an opinion or forming an argument.
• Don’t take things at face value; check sources, view multiple perspectives, and try to find reliable sources for your beliefs.
• Don’t be afraid to ask questions or seek out people with different perspectives to better understand the issue at hand.

“The unexamined life is not worth living.”  Socrates

4. Not Considering Other Perspectives

Another thing to consider when it comes to poor critical thinking is failing to consider other perspectives. After all, if you’re not taking the time to look at things from different angles, then you are limiting yourself .

For example, say you’re trying to come up with solutions for a problem at work. You might think that the first solution you come up with is the best one. But if you take the time to really brainstorm and consider other perspectives and options, then you might find a better solution.

Assumptions: It’s easy when dissecting an issue to assume that other people’s ideas apply only to them and not necessarily to everyone. Not considering other perspectives oftentimes results in making false assumptions about someone else’s ideas or beliefs. These assumptions can lead to miscommunication or worse.

Ignorance: Not listening and attempting to understand other perspectives can also lead to ignorance. Rather than trying hard to understand how someone else thinks or believes, we can stick with our narrow view of the world and be closed off from new information and experiences that could benefit us in some way. 

By not taking the step of trying to engage with different points of view, we risk missing out on important insights and valuable context that can help us make more informed decisions or form a deeper understanding of an issue or situation.

Tip – So next time you’re approaching an issue or problem critically, try zooming out and looking at things from multiple angles. You’ll soon see why it pays off.

5. Overgeneralizing

This is when you take a single experience or observation and use it to draw conclusions about an entire group or situation. People might do this when they oversimplify their views instead of looking at all the evidence and weighing it up objectively first.

Let’s look at this with an example: You see a tourist asking for directions, and the person who helps them gives some very helpful advice. You might think that all tourists are friendly, but this isn’t necessarily true; you don’t have enough evidence to make such a broad assumption.

Tip – The next time you think of making a snap judgment call about something, consider taking the time to look at all sides of the story first before coming to any conclusions.

6. Neglecting Creative Thinking

Poor critical thinking examples can also include neglecting to come up with creative ideas or solutions. It’s great to be able to analyze a situation and make decisions based on facts, but sometimes it’s just as important to challenge the status quo and come up with new, innovative solutions.

Creative thinking is about being able to blend facts and existing ideas together in a way that produces something new, is more effective, or increases efficiency. Neglecting this form of critical thinking can lead to missed opportunities as well as poor decision-making.

It helps you assess a situation from different angles and perspectives. It’s not enough to just identify the problem; you have to find a solution that works best for everyone involved. 

Tip – Here are some ways you can start incorporating creative thinking into your problem-solving:

• Brainstorming: Give yourself time to think of different approaches and techniques.
• Incorporating input from others: Get feedback from others who are knowledgeable about the issue.
• Identifying trends: look for patterns that could inform your approach.
• Re-framing the problem : ask yourself if there is another way you could interpret the issue.
• Experimenting: Try different methods until you find one that works best.

7. Listening to Biased Sources

When it comes to critical thinking, one of the biggest mistakes you can make is listening to biased sources. They are ones that already have an agenda when it comes to your opinion. They want you to believe a certain way, and they’re going to do whatever they can to make that happen.

This kind of source will often present “facts” in a way that skews your perspective, and even if they’re telling the truth, they’ll leave out important context. This is why it’s always important to find multiple sources and look at the information objectively.

Here are some red flags that might tip you off when someone is being biased:

• They use inflammatory language or negative stereotypes .
• They cherry-pick data and leave out essential context.
• Their arguments rely more on personal attacks than on facts.
• They bring up irrelevant topics just to distract from the facts.

Tip – If you start seeing any of these signs, it’s time to take a step back, recognize what’s happening, and look for more reliable sources instead. Remember: critical thinking requires an open mind and plenty of research.

8. Confirmation Bias: Seeking Data That Confirms Your Own Beliefs

Another critical thinking error is confirmation bias. This typically happens when you’re trying to prove a point you already believe in and only seek out or interpret data that confirms what you already think.

For example, if you happen to be a firm believer in the benefits of the keto diet but are presented with evidence that shows the diet is bad for your health, chances are your confirmation bias will kick in. You’ll ignore or discount the evidence and instead look for data that confirms your own beliefs .

Tip – Confirmation bias can happen through a deliberate attempt to ignore contradictory information. The result is that you end up creating a false illusion. All the information out there supports your beliefs. So be aware of every step when making decisions and act accordingly.

9. False Dilemma

This is when someone presents two options as if there were no other alternatives, but usually there are more options than just those two.

For example, say a member of your team tells you that you have to either choose her idea or put the project on hold. This is a false dilemma; in reality, the project could move forward using some combination of ideas from all members of the team.

Tip – False dilemmas are sometimes used to manipulate people into making decisions they wouldn’t otherwise make. If someone ever presents you with only two options and claims that it’s an either/or situation, be sure to stop and think critically about whether or not there are truly any other possibilities.

10. Straw Man Argument

A straw man argument is a logical fallacy that involves misrepresenting or distorting an opponent’s position to make it easier to refute. It’s a common tactic used to make an argument look stronger than it is.

It’s important to remember that using straw man arguments does not help support an argument; rather, it detracts from its validity and damages its credibility. 

Tip – The best way to win an argument is to focus on the facts and present well-thought-out evidence in support of your positions rather than resorting to logical fallacies like the straw man argument.

11. Slippery Slope Fallacy

The slippery slope fallacy is a particularly dangerous one to make in critical thinking. It’s an attempt to predict a seemingly inevitable outcome from a supposed “first step.” When you use this fallacy, you might find yourself saying something like, “If A happens, then it’s only a matter of time before Z happens; obviously, A must be prevented.”

This type of reasoning is usually flawed because it ignores reality. For example, if someone argues that legalizing marijuana will inevitably lead to addiction and economic ruin, they are ignoring the fact that there are several factors at play, not just the legalization.

Tip – It’s important to avoid this fallacy when critically examining an argument because it can often lead people astray or cloud their judgment. Make sure to check your premises carefully and ask yourself if what you’re saying is based on reality or just speculation.

12. Expecting Perfection or the Impossible

A common mistake people make when trying to think critically is expecting perfection or the impossible. This occurs when a person outlines a goal that is either unattainable or not completely realistic.

For example, someone might set out to solve a complicated problem in one day, even though it requires time and effort to build up the skills or resources needed to get the job done. Instead of setting themselves up for failure from the beginning, they should break down the problem into smaller, more attainable tasks.

It’s important to recognize that critical thinking isn’t about being perfect; it’s about understanding your limitations and working within them to come up with creative solutions.

Letting go of expectations that are unrealistic or unattainable will help you become a better problem solver and critical thinker.

13. Misinterpreting Data and Statistics

When it comes to critical thinking, data, and statistics, they don’t lie, or do they? Unfortunately, many times people misinterpret data and statistics, which can be a major critical thinking mistake.

Take the example of a study that claims eating pizza is healthier than eating chicken. Sure, that could be true based on this particular study. But without looking further into the details of the study, such as the number of participants or sample size, you can’t form an accurate opinion.

Drawing Conclusions Too Quickly: It’s important to analyze background information and other data points in order to draw more meaningful conclusions. Without looking at the complete picture, you could come away with a conclusion based solely on surface-level information that just isn’t accurate.

Drawing the Wrong Conclusions: Critical thinking is key here. While one might conclude that pizza is healthier than chicken from the first example, it’s possible that there were elements of bias in the study. well-rounded.

Tip – Do not jump to conclusions or accept claims without evidence. Look for patterns, trends and outliers in the data. Ask questions and seek explanations. Evaluate the arguments and evidence from different perspectives.

14. Circular Reasoning

If you’re not familiar, this is a logical fallacy where the argument doesn’t have any actual basis or supporting evidence.

Instead, it just keeps going around in circles, with the conclusion supporting the same premise that was already established in the original statement. It’s an assumption masquerading as an argument.

So how can you recognize this fallacy when you see it? Here are some common examples:

• “People should obey the law because it is the law.” This statement presumes that people should accept and obey laws simply because they exist. There is no further explanation or evidence provided as to why they exist or why they should be obeyed.
• Circular reasoning provides a false sense of security. It might sound convincing at first, but when you look at it, you’ll quickly see that there’s no real evidence or supporting facts behind it. Critical thinkers recognize this practice for what it is: an invalid argument that’s desperately trying to pass itself off as convincing logic.

Tip – To avoid circular reasoning, one should provide independent evidence or reasons to support the conclusion, and avoid restating the conclusion in different words.

Examples of Poor Reasoning

Critical thinking doesn’t always get the best press, and that’s probably because it gets abused. Poor critical thinking is littered with fallacies, confirmation biases, and leaps of logic that make it a frustrating affair.

We often see Bad critical thinking in everyday life. Here are some examples:

• jumping to conclusions and reaching a decision too quickly without considering all of the evidence.
• overgeneralizing and drawing broad conclusions from a single event or data point
• Selective Thinking Focus on selected pieces of evidence that support your position and ignore other information.
• Emotional reasoning: making decisions based on how you feel rather than facts and logic.
• Ad hominem attacks attack someone personally to invalidate their arguments instead of focusing on the argument itself.
• False dilemma: assuming there are only two possible sides to an issue or two possible outcomes when in reality there are more options or scenarios.

In conclusion, examples of bad critical thinking can be found in many aspects of our lives, such as politics, media, education, and personal decisions. They can lead to faulty reasoning, biased arguments, fallacious claims, and poor judgment.

To avoid bad critical thinking, we should always question our assumptions, seek evidence, consider alternative perspectives, and evaluate the consequences of our actions. By doing so, we can improve our thinking skills and make better choices for ourselves and others.

10 examples of critical thinking that changed the world

It’s fair to say that Einstein was using critical thinking skills during the 10 years that it took him to create his Theory of General Relativity. Other physicists assumed that the differences in the ways that bodies fall were too small to be of significance, but Einstein—a 28-year-old clerk at a patent office—could see that these details deserved further investigation.

He had to come up with another, more creative, solution.

“Suddenly a thought struck me,” he recalled. “If a man falls freely, he would not feel his weight… This simple thought experiment… led me to the theory of gravity.”

From this he predicted the existence of gravitational waves, which control how every sun, planet, and object in our universe behaves.

In 2016, the LIGO collaboration proved him right: they announced their first direct detection of gravitational waves in “the scientific breakthrough of the century.” Professor Stephen Hawking said the discovery had “the potential to revolutionize astronomy.”

“Being bold enough to let your mind go where good arguments take you, even if it’s to places that make you feel uncomfortable, may lead you to discoveries about the world and yourself.” (Critical Thinking: The Art of Argument, by George W. Rainbolt and Sandra L. Dwyer)

Einstein’s Theory of General Relativity places him among the most influential nonconformists, mavericks, and free-thinkers in history. Charles Darwin might also spring to mind. Maybe Galileo, Marie Curie, or Simone de Beauvoir.

We know them as geniuses, eccentrics, independent spirits, or even rebels. But what they all have in common is the ability to think creatively and critically about the world, putting aside their peers’ ignorance or assumptions to see new connections in the most mundane situations and change our view of the universe. They are critical thinkers.

1. Albert Einstein

C.P. Snow put it best: “One of [Einstein’s] greatest intellectual gifts, in small matters as well as great, was to strip off the irrelevant frills from a problem.”

(From Einstein: The First Hundred Years )

If you take one critical thinking tip from Einstein, make it…

If something looks wrong, then it’s probably worth finding out why. Trust your own judgement based on the facts, not the assumptions of others, and look for a solution within the details.

2. Charles Darwin

Darwin’s ability to see new connections in mundane situations led him to map out a new theory—evolution—that changed the way we saw the world.

If you take one critical thinking tip from Darwin, make it…

Sometimes the most profound discoveries are hidden in seemingly unlikely places; look where others don’t, and enjoy the sense of discovery and excitement.

3. Galileo Galilei

Pioneering astronomer, philosopher, and—after his discoveries caused uproar in lazy thinkers within religious circles—“ defender of truth in the face of ignorance. ”

If you take one critical thinking tip from Galileo, make it…

Great critical thinkers evaluate arguments to see how they stand up, putting to one side the conclusions and assumptions of others—and filter for themselves what resonates as right or wrong.

4. Martin Luther King, Jr.

Inspired millions with his talent for argument; his “I have a dream” speech—a rallying cry for equal rights—still resonates 50 years on.

If you take one critical thinking tip from Martin Luther King Jr, make it…

Developing a strategy, organizing an argument, and learning the art of persuasion are the keys to changing the world.

5. Simone de Beauvoir

The most radical feminist thinker of the 20th century;  The Second Sex  was the first work to argue for equality that respected a woman’s individuality and voice.

If you take one critical thinking tip from Simone de Beauvoir, make it…

Don’t be afraid to think differently, even if that means challenging the basis of society itself.

6. Edwin Hubble

Discovered galaxies beyond the Milky Way—and proved that they were expanding—simply by gathering and analyzing more data than anyone else.

If you take one critical thinking tip from Edwin Hubble, make it…

Evidence, evidence, evidence. The more you have, and the more you can filter it to get to what’s really going on, the better your conclusion will be.

7. Marie Curie

Paved the way for x-rays and cancer treatment; her sense that pitchblende must include unknown radioactive elements led to the discovery of polonium and radium.

If you take one critical thinking tip from Marie Curie, make it…

Critical thinking is nothing to do with negativity or nitpicking. It’s about asking questions—the right questions. It’s about not accepting things on trust.

8. Sir Isaac Newton

Discovered universal gravitation “by thinking on it continually.” A genius known for a relentless passion for putting everything to rigorous test.

If you take one critical thinking tip from Sir Isaac Newton, make it…

Persistence in thinking and questioning the world around you is the key to more creative solutions where others see only masses of information.

9. Stanislav Petrov

Saved the world from a nuclear disaster during the Cold War; Petrov spotted a false computer report of an American missile strike and, trusting the facts at hand, halted a mistaken counter strike.

If you take one critical thinking tip from Stanislav Petrov, make it…

Form your own judgement based on the facts, and—once you’re sure of your ground—be willing to back it against all comers.

10. W. E. B. Du Bois

Inspired American civil rights movements by refusing to accept that some inequality could be exchanged for legal rights—a view held by other black intellectuals—and publishing his ideas in The Souls of Black Folk .

If you take one critical thinking tip from W. E. B. Du Bois, make it…

Critical thinking is important because it is what makes us adaptable, enables us to act independently, and allows us to move beyond what we already know or guess.

Work from home (WFH) has created many problems for people such as long working hours, neck and back pain, and even having multiple cups of coffee every day. Now that organizations are prioritizing fully remote or blended working models, such scenarios are impossible to ignore.

An extremely unhealthy habit that is a product of working at home is the high consumption of coffee. Studies suggest that several coffee aficionados use the beverage as a substitute for breakfast.  Drinking coffee may seem harmless but search the internet and you will find a long list of its disadvantages—from restlessness and insomnia to weight gain, anxiety and risk of heart attacks in young adults. But then you will find as many links listing the advantages of drinking coffee (if it’s within a certain limit).

Does that sound confusing? Which source should you trust then? By thinking critically, you can come to a conclusion that is logical.

This is just one of the examples of critical thinking in everyday life and its importance. We face many more small and big critical thinking examples in real life.

If you think it may not always be possible to apply critical thinking, you can follow the Ladder of Inference framework from Harappa Education’s Thinking Critically course. It is a four-step approach to understand how you can process information. The course covers several examples of critical thinking to explain it in detail.

To understand this better, let’s see some examples of critical thinking:

Critical thinking examples in the workplace.

Here are some common examples of critical thinking that will help you understand why it’s an essential skill in professional life:

Promoting a teamwork approach to problem-solving

As a team leader, the job of encouraging your team to work towards solving a problem falls on your shoulders. But every individual in a team may come up with different inputs and points of view.

You must logically analyze team members’ inputs. And then offer constructive criticism while sharing your own opinion on the situation. This is one of the common critical thinking examples in the workplace.

Self-evaluating your contributions

Imagine that your chief operating officer creates a new target for the organization. Now it’s your right and responsibility to use critical thinking skills examples and evaluate your contribution to reach the target.

Knowing how your contribution is important will help you discover ways to improve your performance. The result will show the impact your work has made, whether it’s solving a critical bug or coming up with a creative way to approach possible clients. Studying a few critical thinking skills examples will help you analyze your situation better.

This is among the most common critical thinker examples you can find and follow in every organization.

It’s evident from these examples of critical thinking that it’s a valuable skill every employee should strengthen. From efficient decision-making to navigating conflicts, thinking critically help you evaluate situations better instead of jumping to hasty and half-baked conclusions.

Examples of Critical Thinking in Real Life

Choosing a Career Path

Should I go for a full-time college or enroll in an online course? Which stream do I choose? Should I try to get a job in a private organization, work as a consultant, or move towards opening a start-up? We all face such dilemmas in our lives at some point or the other. But every option comes with its pros and cons and, therefore, it’s important to choose carefully.

Such critical thinking examples in everyday life highlight the importance of this process. Choosing the right career path certainly takes time. So as a critical thinker, you weigh the pros and cons of every option.

Also, consider the professional, financial and social context in the form of some critical thinking examples in real life. Know your interest and skill set. Answer questions such as “What is important for me?” and “Why is this important for me?”

Don’t go ahead right after making a choice. If you look at some critical thinker examples, you will understand the impact your chosen path will have in the next one, five and 10 years. Accordingly, you may like to rethink your career path. To be able to do this, some critical thinking will be required.

Evaluating Online Information

There are other examples of critical thinking in everyday life as well. There are hundreds of fake news items that we come across every day on the internet or social media. How do we find the truth among so much noise? Critical thinking can come to your aid.

We come across these and many more critical thinking skills examples in the digital world. With the exchange of information increasing by the minute, the need for critical thinking skills is only increasing.

But asking certain questions will help you process such information.

Who published the article?

What are their sources of information?

What are their intentions?

Are they representing themselves or someone else?

Don’t you think if most social media users ask themselves these questions, social media wars will reduce?

Critical thinker examples and applications can be found inside as well as outside classrooms and meeting rooms. So start working on your critical thinking skills now. Join Harappa Education’s Thinking Critically course, which explains the essential techniques with the help of a few great critical thinker examples. Empower yourself to make qualified decisions.

What Critical Thinking Looks Like: Real Examples

Critical thinking means being able to think clearly and rationally, understanding the logical connection between ideas. It’s about analyzing information, evaluating evidence, and making informed decisions. Let’s look at some everyday examples of critical thinking to see how it works in different situations. This will help us see how critical thinking can improve our decision-making in daily life.

The Significance of Critical Thinking

Critical thinking helps people make smart decisions. It allows them to analyze situations and make choices based on evidence and reasoning. For example, in problem-solving, critical thinkers can find the main causes, consider different options, and find effective solutions. In risk analysis, critical thinking helps assess potential outcomes, understand the impact of different actions, and make decisions to reduce risks.

In hiring, critical thinking helps assess candidates’ problem-solving skills, decision-making, and overall potential to contribute. Recruiters and hiring managers use critical thinking to evaluate if candidates can think analytically and independently for specific roles.

Outside of academics, critical thinking is also important. It helps people make informed choices as consumers, assess the reliability of online information, and solve everyday problems that require logic and creativity. These real-life examples show how critical thinking is useful in different parts of life.

Defining Critical Thinking in Action

Examples in problem-solving scenarios.

Critical thinking is essential in real-life problem-solving scenarios.

For example, when encountered with a complex task at work, individuals with strong critical thinking skills can break down the problem into manageable parts, identify possible solutions, and make informed decisions to resolve the issue effectively. In risk assessment , critical thinking plays a pivotal role in identifying potential drawbacks, analyzing the likelihood and impact of those risks, and developing proactive strategies to mitigate them. For instance, a project manager may use critical thinking to anticipate and address potential obstacles that could impact a project’s success. Furthermore, in data analysis, critical thinking helps individuals interpret information accurately and make informed decisions based on the available data.

For example, in marketing, professionals may use critical thinking skills to analyze consumer behavior data and develop strategic marketing campaigns. Therefore, critical thinking is a beneficial skill that can be applied in various aspects of professional life to enhance problem-solving, risk assessment, and decision-making processes.

Risk Analysis and Mitigation Instances

Risk analysis is important for businesses and organizations. It’s used in financial investment, project management, and cybersecurity. In financial investment, it helps assess risks and returns. In project management, it finds obstacles and creates plans to deal with them. In cybersecurity, it identifies digital threats and vulnerabilities.

To reduce risks, organizations can take preventive steps. These include backing up important data, improving security, and training staff on cybersecurity. For example, if phishing attacks are a big risk, companies can train employees to recognize and avoid them.

Various tools and methods can be used for risk analysis. Some include SWOT analysis , Monte Carlo simulation, and decision trees. These help identify risks and their impact, so effective strategies can be made. SWOT analysis, for instance, helps find strengths and weaknesses, as well as external opportunities and threats. This helps make better decisions and manage risks.

Interpreting Data and Making Informed Decisions

Interpreting data to make decisions at work is important. For instance, a company can use customer feedback to improve products or marketing.

But there are pitfalls, like confirmation bias, where people focus on information that confirms their ideas.

It’s important to think critically when using data. This means evaluating its relevance and reliability, considering other perspectives, and potential unintended consequences.

Good critical thinking is important for making informed decisions at work.

Professionals can showcase their critical thinking skills by getting professional practice credentials like Deakin’s. This shows they can use data to make decisions.

The Application in Hiring and Evaluating Talent

Critical thinking is important for hiring and evaluating talent.

An example of this is assessing a candidate’s problem-solving skills. For example, a hiring manager may ask the interviewee to share specific examples of how they have solved problems in previous roles.

Additionally, critical thinking is important for data analysis in talent evaluation. Recruiters can use critical thinking to interpret data from sources like resumes, work samples, and interviews to make unbiased decisions.

These methods help organizations hire and evaluate talent based on their true potential, leading to more effective and successful team members.

How To Enhance Your Critical Thinking Capabilities

Validating your critical thinking prowess: credentials and practice.

Credentials and practice are important for showing how well someone can think critically at work. Getting professional practice credentials can prove that a person can think critically when solving problems, evaluating risks, analyzing data, and hiring talent. These credentials give real proof of a person’s critical thinking skills, which can be shown to potential employers.

In different work situations, critical thinking skills are used for tasks like analyzing market trends, finding new solutions to tough problems, and making smart decisions based on available data. To get better at critical thinking in their job, people can learn continuously, take part in solving problems, and ask for advice from coworkers and mentors. By actively using critical thinking in their jobs, people can improve their analytical skills and make better decisions based on evidence and logic.

FAQs on Critical Thinking: Addressing Common Inquiries

Exploring non-academic illustrations of critical thinking.

Critical thinking is important outside of school too. It involves analyzing situations, identifying key issues, and finding practical solutions. For instance, in a business, critical thinking helps employees understand customer needs, plan for growth, and solve operational problems. In risk analysis, people use critical thinking to evaluate threats, predict consequences, and create preventive measures. This is important in fields like emergency management.

Also, critical thinking is used to interpret data and make informed decisions. In public policy, analysts use it to interpret demographic and economic data for decision-making and resource allocation. These examples show how critical thinking goes beyond traditional education.

Critical Thinking

Critical thinking is a widely accepted educational goal. Its definition is contested, but the competing definitions can be understood as differing conceptions of the same basic concept: careful thinking directed to a goal. Conceptions differ with respect to the scope of such thinking, the type of goal, the criteria and norms for thinking carefully, and the thinking components on which they focus. Its adoption as an educational goal has been recommended on the basis of respect for students’ autonomy and preparing students for success in life and for democratic citizenship. “Critical thinkers” have the dispositions and abilities that lead them to think critically when appropriate. The abilities can be identified directly; the dispositions indirectly, by considering what factors contribute to or impede exercise of the abilities. Standardized tests have been developed to assess the degree to which a person possesses such dispositions and abilities. Educational intervention has been shown experimentally to improve them, particularly when it includes dialogue, anchored instruction, and mentoring. Controversies have arisen over the generalizability of critical thinking across domains, over alleged bias in critical thinking theories and instruction, and over the relationship of critical thinking to other types of thinking.

Use of the term ‘critical thinking’ to describe an educational goal goes back to the American philosopher John Dewey (1910), who more commonly called it ‘reflective thinking’. He defined it as

active, persistent and careful consideration of any belief or supposed form of knowledge in the light of the grounds that support it, and the further conclusions to which it tends. (Dewey 1910: 6; 1933: 9)

and identified a habit of such consideration with a scientific attitude of mind. His lengthy quotations of Francis Bacon, John Locke, and John Stuart Mill indicate that he was not the first person to propose development of a scientific attitude of mind as an educational goal.

In the 1930s, many of the schools that participated in the Eight-Year Study of the Progressive Education Association (Aikin 1942) adopted critical thinking as an educational goal, for whose achievement the study’s Evaluation Staff developed tests (Smith, Tyler, & Evaluation Staff 1942). Glaser (1941) showed experimentally that it was possible to improve the critical thinking of high school students. Bloom’s influential taxonomy of cognitive educational objectives (Bloom et al. 1956) incorporated critical thinking abilities. Ennis (1962) proposed 12 aspects of critical thinking as a basis for research on the teaching and evaluation of critical thinking ability.

Since 1980, an annual international conference in California on critical thinking and educational reform has attracted tens of thousands of educators from all levels of education and from many parts of the world. Also since 1980, the state university system in California has required all undergraduate students to take a critical thinking course. Since 1983, the Association for Informal Logic and Critical Thinking has sponsored sessions in conjunction with the divisional meetings of the American Philosophical Association (APA). In 1987, the APA’s Committee on Pre-College Philosophy commissioned a consensus statement on critical thinking for purposes of educational assessment and instruction (Facione 1990a). Researchers have developed standardized tests of critical thinking abilities and dispositions; for details, see the Supplement on Assessment . Educational jurisdictions around the world now include critical thinking in guidelines for curriculum and assessment. Political and business leaders endorse its importance.

For details on this history, see the Supplement on History .

2. Examples and Non-Examples

Before considering the definition of critical thinking, it will be helpful to have in mind some examples of critical thinking, as well as some examples of kinds of thinking that would apparently not count as critical thinking.

Dewey (1910: 68–71; 1933: 91–94) takes as paradigms of reflective thinking three class papers of students in which they describe their thinking. The examples range from the everyday to the scientific.

Transit : “The other day, when I was down town on 16th Street, a clock caught my eye. I saw that the hands pointed to 12:20. This suggested that I had an engagement at 124th Street, at one o'clock. I reasoned that as it had taken me an hour to come down on a surface car, I should probably be twenty minutes late if I returned the same way. I might save twenty minutes by a subway express. But was there a station near? If not, I might lose more than twenty minutes in looking for one. Then I thought of the elevated, and I saw there was such a line within two blocks. But where was the station? If it were several blocks above or below the street I was on, I should lose time instead of gaining it. My mind went back to the subway express as quicker than the elevated; furthermore, I remembered that it went nearer than the elevated to the part of 124th Street I wished to reach, so that time would be saved at the end of the journey. I concluded in favor of the subway, and reached my destination by one o’clock.” (Dewey 1910: 68-69; 1933: 91-92)

Ferryboat : “Projecting nearly horizontally from the upper deck of the ferryboat on which I daily cross the river is a long white pole, having a gilded ball at its tip. It suggested a flagpole when I first saw it; its color, shape, and gilded ball agreed with this idea, and these reasons seemed to justify me in this belief. But soon difficulties presented themselves. The pole was nearly horizontal, an unusual position for a flagpole; in the next place, there was no pulley, ring, or cord by which to attach a flag; finally, there were elsewhere on the boat two vertical staffs from which flags were occasionally flown. It seemed probable that the pole was not there for flag-flying.

“I then tried to imagine all possible purposes of the pole, and to consider for which of these it was best suited: (a) Possibly it was an ornament. But as all the ferryboats and even the tugboats carried poles, this hypothesis was rejected. (b) Possibly it was the terminal of a wireless telegraph. But the same considerations made this improbable. Besides, the more natural place for such a terminal would be the highest part of the boat, on top of the pilot house. (c) Its purpose might be to point out the direction in which the boat is moving.

“In support of this conclusion, I discovered that the pole was lower than the pilot house, so that the steersman could easily see it. Moreover, the tip was enough higher than the base, so that, from the pilot's position, it must appear to project far out in front of the boat. Morevoer, the pilot being near the front of the boat, he would need some such guide as to its direction. Tugboats would also need poles for such a purpose. This hypothesis was so much more probable than the others that I accepted it. I formed the conclusion that the pole was set up for the purpose of showing the pilot the direction in which the boat pointed, to enable him to steer correctly.” (Dewey 1910: 69-70; 1933: 92-93)

Bubbles : “In washing tumblers in hot soapsuds and placing them mouth downward on a plate, bubbles appeared on the outside of the mouth of the tumblers and then went inside. Why? The presence of bubbles suggests air, which I note must come from inside the tumbler. I see that the soapy water on the plate prevents escape of the air save as it may be caught in bubbles. But why should air leave the tumbler? There was no substance entering to force it out. It must have expanded. It expands by increase of heat, or by decrease of pressure, or both. Could the air have become heated after the tumbler was taken from the hot suds? Clearly not the air that was already entangled in the water. If heated air was the cause, cold air must have entered in transferring the tumblers from the suds to the plate. I test to see if this supposition is true by taking several more tumblers out. Some I shake so as to make sure of entrapping cold air in them. Some I take out holding mouth downward in order to prevent cold air from entering. Bubbles appear on the outside of every one of the former and on none of the latter. I must be right in my inference. Air from the outside must have been expanded by the heat of the tumbler, which explains the appearance of the bubbles on the outside. But why do they then go inside? Cold contracts. The tumbler cooled and also the air inside it. Tension was removed, and hence bubbles appeared inside. To be sure of this, I test by placing a cup of ice on the tumbler while the bubbles are still forming outside. They soon reverse” (Dewey 1910: 70–71; 1933: 93–94).

Dewey (1910, 1933) sprinkles his book with other examples of critical thinking. We will refer to the following.

Weather : A man on a walk notices that it has suddenly become cool, thinks that it is probably going to rain, looks up and sees a dark cloud obscuring the sun, and quickens his steps (1910: 6–10; 1933: 9–13).

Disorder : A man finds his rooms on his return to them in disorder with his belongings thrown about, thinks at first of burglary as an explanation, then thinks of mischievous children as being an alternative explanation, then looks to see whether valuables are missing, and discovers that they are (1910: 82–83; 1933: 166–168).

Typhoid : A physician diagnosing a patient whose conspicuous symptoms suggest typhoid avoids drawing a conclusion until more data are gathered by questioning the patient and by making tests (1910: 85–86; 1933: 170).

Blur : A moving blur catches our eye in the distance, we ask ourselves whether it is a cloud of whirling dust or a tree moving its branches or a man signaling to us, we think of other traits that should be found on each of those possibilities, and we look and see if those traits are found (1910: 102, 108; 1933: 121, 133).

Suction pump : In thinking about the suction pump, the scientist first notes that it will draw water only to a maximum height of 33 feet at sea level and to a lesser maximum height at higher elevations, selects for attention the differing atmospheric pressure at these elevations, sets up experiments in which the air is removed from a vessel containing water (when suction no longer works) and in which the weight of air at various levels is calculated, compares the results of reasoning about the height to which a given weight of air will allow a suction pump to raise water with the observed maximum height at different elevations, and finally assimilates the suction pump to such apparently different phenomena as the siphon and the rising of a balloon (1910: 150–153; 1933: 195–198).

Diamond : A passenger in a car driving in a diamond lane reserved for vehicles with at least one passenger notices that the diamond marks on the pavement are far apart in some places and close together in others. Why? The driver suggests that the reason may be that the diamond marks are not needed where there is a solid double line separating the diamond line from the adjoining lane, but are needed when there is a dotted single line permitting crossing into the diamond lane. Further observation confirms that the diamonds are close together when a dotted line separates the diamond lane from its neighbour, but otherwise far apart.

Rash : A woman suddenly develops a very itchy red rash on her throat and upper chest. She recently noticed a mark on the back of her right hand, but was not sure whether the mark was a rash or a scrape. She lies down in bed and thinks about what might be causing the rash and what to do about it. About two weeks before, she began taking blood pressure medication that contained a sulfa drug, and the pharmacist had warned her, in view of a previous allergic reaction to a medication containing a sulfa drug, to be on the alert for an allergic reaction; however, she had been taking the medication for two weeks with no such effect. The day before, she began using a new cream on her neck and upper chest; against the new cream as the cause was mark on the back of her hand, which had not been exposed to the cream. She began taking probiotics about a month before. She also recently started new eye drops, but she supposed that manufacturers of eye drops would be careful not to include allergy-causing components in the medication. The rash might be a heat rash, since she recently was sweating profusely from her upper body. Since she is about to go away on a short vacation, where she would not have access to her usual physician, she decides to keep taking the probiotics and using the new eye drops but to discontinue the blood pressure medication and to switch back to the old cream for her neck and upper chest. She forms a plan to consult her regular physician on her return about the blood pressure medication.

Candidate : Although Dewey included no examples of thinking directed at appraising the arguments of others, such thinking has come to be considered a kind of critical thinking. We find an example of such thinking in the performance task on the Collegiate Learning Assessment (CLA+), which its sponsoring organization describes as

a performance-based assessment that provides a measure of an institution’s contribution to the development of critical-thinking and written communication skills of its students. (Council for Aid to Education 2017)

A sample task posted on its website requires the test-taker to write a report for public distribution evaluating a fictional candidate’s policy proposals and their supporting arguments, using supplied background documents, with a recommendation on whether to endorse the candidate.

Immediate acceptance of an idea that suggests itself as a solution to a problem (e.g., a possible explanation of an event or phenomenon, an action that seems likely to produce a desired result) is “uncritical thinking, the minimum of reflection” (Dewey 1910: 13). On-going suspension of judgment in the light of doubt about a possible solution is not critical thinking (Dewey 1910: 108). Critique driven by a dogmatically held political or religious ideology is not critical thinking; thus Paulo Freire (1968 [1970]) is using the term (e.g., at 1970: 71, 81, 100, 146) in a more politically freighted sense that includes not only reflection but also revolutionary action against oppression. Derivation of a conclusion from given data using an algorithm is not critical thinking.

What is critical thinking? There are many definitions. Ennis (2016) lists 14 philosophically oriented scholarly definitions and three dictionary definitions. Following Rawls (1971), who distinguished his conception of justice from a utilitarian conception but regarded them as rival conceptions of the same concept, Ennis maintains that the 17 definitions are different conceptions of the same concept. Rawls articulated the shared concept of justice as

a characteristic set of principles for assigning basic rights and duties and for determining… the proper distribution of the benefits and burdens of social cooperation. (Rawls 1971: 5)

Bailin et al. (1999b) claim that, if one considers what sorts of thinking an educator would take not to be critical thinking and what sorts to be critical thinking, one can conclude that educators typically understand critical thinking to have at least three features.

• It is done for the purpose of making up one’s mind about what to believe or do.
• The person engaging in the thinking is trying to fulfill standards of adequacy and accuracy appropriate to the thinking.
• The thinking fulfills the relevant standards to some threshold level.

One could sum up the core concept that involves these three features by saying that critical thinking is careful goal-directed thinking. This core concept seems to apply to all the examples of critical thinking described in the previous section. As for the non-examples, their exclusion depends on construing careful thinking as excluding jumping immediately to conclusions, suspending judgment no matter how strong the evidence, reasoning from an unquestioned ideological or religious perspective, and routinely using an algorithm to answer a question.

If the core of critical thinking is careful goal-directed thinking, conceptions of it can vary according to its presumed scope, its presumed goal, one’s criteria and threshold for being careful, and the thinking component on which one focuses As to its scope, some conceptions (e.g., Dewey 1910, 1933) restrict it to constructive thinking on the basis of one’s own observations and experiments, others (e.g., Ennis 1962; Fisher & Scriven 1997; Johnson 1992) to appraisal of the products of such thinking. Ennis (1991) and Bailin et al. (1999b) take it to cover both construction and appraisal. As to its goal, some conceptions restrict it to forming a judgment (Dewey 1910, 1933; Lipman 1987; Facione 1990a). Others allow for actions as well as beliefs as the end point of a process of critical thinking (Ennis 1991; Bailin et al. 1999b). As to the criteria and threshold for being careful, definitions vary in the term used to indicate that critical thinking satisfies certain norms: “intellectually disciplined” (Scriven & Paul 1987), “reasonable” (Ennis 1991), “skillful” (Lipman 1987), “skilled” (Fisher & Scriven 1997), “careful” (Bailin & Battersby 2009). Some definitions specify these norms, referring variously to “consideration of any belief or supposed form of knowledge in the light of the grounds that support it and the further conclusions to which it tends” (Dewey 1910, 1933); “the methods of logical inquiry and reasoning” (Glaser 1941); “conceptualizing, applying, analyzing, synthesizing, and/or evaluating information gathered from, or generated by, observation, experience, reflection, reasoning, or communication” (Scriven & Paul 1987); the requirement that “it is sensitive to context, relies on criteria, and is self-correcting” (Lipman 1987); “evidential, conceptual, methodological, criteriological, or contextual considerations” (Facione 1990a); and “plus-minus considerations of the product in terms of appropriate standards (or criteria)” (Johnson 1992). Stanovich and Stanovich (2010) propose to ground the concept of critical thinking in the concept of rationality, which they understand as combining epistemic rationality (fitting one’s beliefs to the world) and instrumental rationality (optimizing goal fulfillment); a critical thinker, in their view, is someone with “a propensity to override suboptimal responses from the autonomous mind” (2010: 227). These variant specifications of norms for critical thinking are not necessarily incompatible with one another, and in any case presuppose the core notion of thinking carefully. As to the thinking component singled out, some definitions focus on suspension of judgment during the thinking (Dewey 1910; McPeck 1981), others on inquiry while judgment is suspended (Bailin & Battersby 2009), others on the resulting judgment (Facione 1990a), and still others on the subsequent emotive response (Siegel 1988).

In educational contexts, a definition of critical thinking is a “programmatic definition” (Scheffler 1960: 19). It expresses a practical program for achieving an educational goal. For this purpose, a one-sentence formulaic definition is much less useful than articulation of a critical thinking process, with criteria and standards for the kinds of thinking that the process may involve. The real educational goal is recognition, adoption and implementation by students of those criteria and standards. That adoption and implementation in turn consists in acquiring the knowledge, abilities and dispositions of a critical thinker.

Conceptions of critical thinking generally do not include moral integrity as part of the concept. Dewey, for example, took critical thinking to be the ultimate intellectual goal of education, but distinguished it from the development of social cooperation among school children, which he took to be the central moral goal. Ennis (1996, 2011) added to his previous list of critical thinking dispositions a group of dispositions to care about the dignity and worth of every person, which he described as a “correlative” (1996) disposition without which critical thinking would be less valuable and perhaps harmful. An educational program that aimed at developing critical thinking but not the correlative disposition to care about the dignity and worth of every person, he asserted, “would be deficient and perhaps dangerous” (Ennis 1996: 172).

Dewey thought that education for reflective thinking would be of value to both the individual and society; recognition in educational practice of the kinship to the scientific attitude of children’s native curiosity, fertile imagination and love of experimental inquiry “would make for individual happiness and the reduction of social waste” (Dewey 1910: iii). Schools participating in the Eight-Year Study took development of the habit of reflective thinking and skill in solving problems as a means to leading young people to understand, appreciate and live the democratic way of life characteristic of the United States (Aikin 1942: 17–18, 81). Harvey Siegel (1988: 55–61) has offered four considerations in support of adopting critical thinking as an educational ideal. (1) Respect for persons requires that schools and teachers honour students’ demands for reasons and explanations, deal with students honestly, and recognize the need to confront students’ independent judgment; these requirements concern the manner in which teachers treat students. (2) Education has the task of preparing children to be successful adults, a task that requires development of their self-sufficiency. (3) Education should initiate children into the rational traditions in such fields as history, science and mathematics. (4) Education should prepare children to become democratic citizens, which requires reasoned procedures and critical talents and attitudes. To supplement these considerations, Siegel (1988: 62–90) responds to two objections: the ideology objection that adoption of any educational ideal requires a prior ideological commitment and the indoctrination objection that cultivation of critical thinking cannot escape being a form of indoctrination.

Despite the diversity of our 11 examples, one can recognize a common pattern. Dewey analyzed it as consisting of five phases:

• suggestions , in which the mind leaps forward to a possible solution;
• an intellectualization of the difficulty or perplexity into a problem to be solved, a question for which the answer must be sought;
• the use of one suggestion after another as a leading idea, or hypothesis , to initiate and guide observation and other operations in collection of factual material;
• the mental elaboration of the idea or supposition as an idea or supposition ( reasoning , in the sense on which reasoning is a part, not the whole, of inference); and
• testing the hypothesis by overt or imaginative action. (Dewey 1933: 106–107; italics in original)

The process of reflective thinking consisting of these phases would be preceded by a perplexed, troubled or confused situation and followed by a cleared-up, unified, resolved situation (Dewey 1933: 106). The term ‘phases’ replaced the term ‘steps’ (Dewey 1910: 72), thus removing the earlier suggestion of an invariant sequence. Variants of the above analysis appeared in (Dewey 1916: 177) and (Dewey 1938: 101–119).

The variant formulations indicate the difficulty of giving a single logical analysis of such a varied process. The process of critical thinking may have a spiral pattern, with the problem being redefined in the light of obstacles to solving it as originally formulated. For example, the person in Transit might have concluded that getting to the appointment at the scheduled time was impossible and have reformulated the problem as that of rescheduling the appointment for a mutually convenient time. Further, defining a problem does not always follow after or lead immediately to an idea of a suggested solution. Nor should it do so, as Dewey himself recognized in describing the physician in Typhoid as avoiding any strong preference for this or that conclusion before getting further information (Dewey 1910: 85; 1933: 170). People with a hypothesis in mind, even one to which they have a very weak commitment, have a so-called “confirmation bias” (Nickerson 1998): they are likely to pay attention to evidence that confirms the hypothesis and to ignore evidence that counts against it or for some competing hypothesis. Detectives, intelligence agencies, and investigators of airplane accidents are well advised to gather relevant evidence systematically and to postpone even tentative adoption of an explanatory hypothesis until the collected evidence rules out with the appropriate degree of certainty all but one explanation. Dewey’s analysis of the critical thinking process can be faulted as well for requiring acceptance or rejection of a possible solution to a defined problem, with no allowance for deciding in the light of the available evidence to suspend judgment. Further, given the great variety of kinds of problems for which reflection is appropriate, there is likely to be variation in its component events. Perhaps the best way to conceptualize the critical thinking process is as a checklist whose component events can occur in a variety of orders, selectively, and more than once. These component events might include (1) noticing a difficulty, (2) defining the problem, (3) dividing the problem into manageable sub-problems, (4) formulating a variety of possible solutions to the problem or sub-problem, (5) determining what evidence is relevant to deciding among possible solutions to the problem or sub-problem, (6) devising a plan of systematic observation or experiment that will uncover the relevant evidence, (7) carrying out the plan of systematic observation or experimentation, (8) noting the results of the systematic observation or experiment, (9) gathering relevant testimony and information from others, (10) judging the credibility of testimony and information gathered from others, (11) drawing conclusions from gathered evidence and accepted testimony, and (12) accepting a solution that the evidence adequately supports (cf. Hitchcock 2017: 485).

Checklist conceptions of the process of critical thinking are open to the objection that they are too mechanical and procedural to fit the multi-dimensional and emotionally charged issues for which critical thinking is urgently needed (Paul 1984). For such issues, a more dialectical process is advocated, in which competing relevant world views are identified, their implications explored, and some sort of creative synthesis attempted.

If one considers the critical thinking process illustrated by the 11 examples, one can identify distinct kinds of mental acts and mental states that form part of it. To distinguish, label and briefly characterize these components is a useful preliminary to identifying abilities, skills, dispositions, attitudes, habits and the like that contribute causally to thinking critically. Identifying such abilities and habits is in turn a useful preliminary to setting educational goals. Setting the goals is in its turn a useful preliminary to designing strategies for helping learners to achieve the goals and to designing ways of measuring the extent to which learners have done so. Such measures provide both feedback to learners on their achievement and a basis for experimental research on the effectiveness of various strategies for educating people to think critically. Let us begin, then, by distinguishing the kinds of mental acts and mental events that can occur in a critical thinking process.

• Observing : One notices something in one’s immediate environment (sudden cooling of temperature in Weather , bubbles forming outside a glass and then going inside in Bubbles , a moving blur in the distance in Blur , a rash in Rash ). Or one notes the results of an experiment or systematic observation (valuables missing in Disorder , no suction without air pressure in Suction pump )
• Feeling : One feels puzzled or uncertain about something (how to get to an appointment on time in Transit , why the diamonds vary in frequency in Diamond ). One wants to resolve this perplexity. One feels satisfaction once one has worked out an answer (to take the subway express in Transit , diamonds closer when needed as a warning in Diamond ).
• Wondering : One formulates a question to be addressed (why bubbles form outside a tumbler taken from hot water in Bubbles , how suction pumps work in Suction pump , what caused the rash in Rash ).
• Imagining : One thinks of possible answers (bus or subway or elevated in Transit , flagpole or ornament or wireless communication aid or direction indicator in Ferryboat , allergic reaction or heat rash in Rash ).
• Inferring : One works out what would be the case if a possible answer were assumed (valuables missing if there has been a burglary in Disorder , earlier start to the rash if it is an allergic reaction to a sulfa drug in Rash ). Or one draws a conclusion once sufficient relevant evidence is gathered (take the subway in Transit , burglary in Disorder , discontinue blood pressure medication and new cream in Rash ).
• Knowledge : One uses stored knowledge of the subject-matter to generate possible answers or to infer what would be expected on the assumption of a particular answer (knowledge of a city’s public transit system in Transit , of the requirements for a flagpole in Ferryboat , of Boyle’s law in Bubbles , of allergic reactions in Rash ).
• Experimenting : One designs and carries out an experiment or a systematic observation to find out whether the results deduced from a possible answer will occur (looking at the location of the flagpole in relation to the pilot’s position in Ferryboat , putting an ice cube on top of a tumbler taken from hot water in Bubbles , measuring the height to which a suction pump will draw water at different elevations in Suction pump , noticing the frequency of diamonds when movement to or from a diamond lane is allowed in Diamond ).
• Consulting : One finds a source of information, gets the information from the source, and makes a judgment on whether to accept it. None of our 11 examples include searching for sources of information. In this respect they are unrepresentative, since most people nowadays have almost instant access to information relevant to answering any question, including many of those illustrated by the examples. However, Candidate includes the activities of extracting information from sources and evaluating its credibility.
• Identifying and analyzing arguments : One notices an argument and works out its structure and content as a preliminary to evaluating its strength. This activity is central to Candidate . It is an important part of a critical thinking process in which one surveys arguments for various positions on an issue.
• Judging : One makes a judgment on the basis of accumulated evidence and reasoning, such as the judgment in Ferryboat that the purpose of the pole is to provide direction to the pilot.
• Deciding : One makes a decision on what to do or on what policy to adopt, as in the decision in Transit to take the subway.

By definition, a person who does something voluntarily is both willing and able to do that thing at that time. Both the willingness and the ability contribute causally to the person’s action, in the sense that the voluntary action would not occur if either (or both) of these were lacking. For example, suppose that one is standing with one’s arms at one’s sides and one voluntarily lifts one’s right arm to an extended horizontal position. One would not do so if one were unable to lift one’s arm, if for example one’s right side was paralyzed as the result of a stroke. Nor would one do so if one were unwilling to lift one’s arm, if for example one were participating in a street demonstration at which a white supremacist was urging the crowd to lift their right arm in a Nazi salute and one were unwilling to express support in this way for the racist Nazi ideology. The same analysis applies to a voluntary mental process of thinking critically. It requires both willingness and ability to think critically, including willingness and ability to perform each of the mental acts that compose the process and to coordinate those acts in a sequence that is directed at resolving the initiating perplexity.

Consider willingness first. We can identify causal contributors to willingness to think critically by considering factors that would cause a person who was able to think critically about an issue nevertheless not to do so (Hamby 2014). For each factor, the opposite condition thus contributes causally to willingness to think critically on a particular occasion. For example, people who habitually jump to conclusions without considering alternatives will not think critically about issues that arise, even if they have the required abilities. The contrary condition of willingness to suspend judgment is thus a causal contributor to thinking critically.

Now consider ability. In contrast to the ability to move one’s arm, which can be completely absent because a stroke has left the arm paralyzed, the ability to think critically is a developed ability, whose absence is not a complete absence of ability to think but absence of ability to think well. We can identify the ability to think well directly, in terms of the norms and standards for good thinking. In general, to be able do well the thinking activities that can be components of a critical thinking process, one needs to know the concepts and principles that characterize their good performance, to recognize in particular cases that the concepts and principles apply, and to apply them. The knowledge, recognition and application may be procedural rather than declarative. It may be domain-specific rather than widely applicable, and in either case may need subject-matter knowledge, sometimes of a deep kind.

Reflections of the sort illustrated by the previous two paragraphs have led scholars to identify the knowledge, abilities and dispositions of a “critical thinker”, i.e., someone who thinks critically whenever it is appropriate to do so. We turn now to these three types of causal contributors to thinking critically. We start with dispositions, since arguably these are the most powerful contributors to being a critical thinker, can be fostered at an early stage of a child’s development, and are susceptible to general improvement (Glaser 1941: 175)

8. Critical Thinking Dispositions

Educational researchers use the term ‘dispositions’ broadly for the habits of mind and attitudes that contribute causally to being a critical thinker. Some writers (e.g., Paul & Elder 2006; Hamby 2014; Bailin & Battersby 2016) propose to use the term ‘virtues’ for this dimension of a critical thinker. The virtues in question, although they are virtues of character, concern the person’s ways of thinking rather than the person’s ways of behaving towards others. They are not moral virtues but intellectual virtues, of the sort articulated by Zagzebski (1996) and discussed by Turri, Alfano, and Greco (2017).

On a realistic conception, thinking dispositions or intellectual virtues are real properties of thinkers. They are general tendencies, propensities, or inclinations to think in particular ways in particular circumstances, and can be genuinely explanatory (Siegel 1999). Sceptics argue that there is no evidence for a specific mental basis for the habits of mind that contribute to thinking critically, and that it is pedagogically misleading to posit such a basis (Bailin et al. 1999a). Whatever their status, critical thinking dispositions need motivation for their initial formation in a child—motivation that may be external or internal. As children develop, the force of habit will gradually become important in sustaining the disposition (Nieto & Valenzuela 2012). Mere force of habit, however, is unlikely to sustain critical thinking dispositions. Critical thinkers must value and enjoy using their knowledge and abilities to think things through for themselves. They must be committed to, and lovers of, inquiry.

A person may have a critical thinking disposition with respect to only some kinds of issues. For example, one could be open-minded about scientific issues but not about religious issues. Similarly, one could be confident in one’s ability to reason about the theological implications of the existence of evil in the world but not in one’s ability to reason about the best design for a guided ballistic missile.

Critical thinking dispositions can usefully be divided into initiating dispositions (those that contribute causally to starting to think critically about an issue) and internal dispositions (those that contribute causally to doing a good job of thinking critically once one has started) (Facione 1990a: 25). The two categories are not mutually exclusive. For example, open-mindedness, in the sense of willingness to consider alternative points of view to one’s own, is both an initiating and an internal disposition.

Using the strategy of considering factors that would block people with the ability to think critically from doing so, we can identify as initiating dispositions for thinking critically attentiveness, a habit of inquiry, self-confidence, courage, open-mindedness, willingness to suspend judgment, trust in reason, wanting evidence for one’s beliefs, and seeking the truth. We consider briefly what each of these dispositions amounts to, in each case citing sources that acknowledge them.

• Attentiveness : One will not think critically if one fails to recognize an issue that needs to be thought through. For example, the pedestrian in Weather would not have looked up if he had not noticed that the air was suddenly cooler. To be a critical thinker, then, one needs to be habitually attentive to one’s surroundings, noticing not only what one senses but also sources of perplexity in messages received and in one’s own beliefs and attitudes (Facione 1990a: 25; Facione, Facione, & Giancarlo 2001).
• Habit of inquiry : Inquiry is effortful, and one needs an internal push to engage in it. For example, the student in Bubbles could easily have stopped at idle wondering about the cause of the bubbles rather than reasoning to a hypothesis, then designing and executing an experiment to test it. Thus willingness to think critically needs mental energy and initiative. What can supply that energy? Love of inquiry, or perhaps just a habit of inquiry. Hamby (2015) has argued that willingness to inquire is the central critical thinking virtue, one that encompasses all the others. It is recognized as a critical thinking disposition by Dewey (1910: 29; 1933: 35), Glaser (1941: 5), Ennis (1987: 12; 1991: 8), Facione (1990a: 25), Bailin et al. (1999b: 294), Halpern (1998: 452), and Facione, Facione, & Giancarlo (2001).
• Self-confidence : Lack of confidence in one’s abilities can block critical thinking. For example, if the woman in Rash lacked confidence in her ability to figure things out for herself, she might just have assumed that the rash on her chest was the allergic reaction to her medication against which the pharmacist had warned her. Thus willingness to think critically requires confidence in one’s ability to inquire (Facione 1990a: 25; Facione, Facione, & Giancarlo 2001).
• Courage : Fear of thinking for oneself can stop one from doing it. Thus willingness to think critically requires intellectual courage (Paul & Elder 2006: 16).
• Open-mindedness : A dogmatic attitude will impede thinking critically. For example, a person who adheres rigidly to a “pro-choice” position on the issue of the legal status of induced abortion is likely to be unwilling to consider seriously the issue of when in its development an unborn child acquires a moral right to life. Thus willingness to think critically requires open-mindedness, in the sense of a willingness to examine questions to which one already accepts an answer but which further evidence or reasoning might cause one to answer differently (Dewey 1933; Facione 1990a; Ennis 1991; Bailin et al. 1999b; Halpern 1998, Facione, Facione, & Giancarlo 2001). Paul (1981) emphasizes open-mindedness about alternative world-views, and recommends a dialectical approach to integrating such views as central to what he calls “strong sense” critical thinking.
• Willingness to suspend judgment : Premature closure on an initial solution will block critical thinking. Thus willingness to think critically requires a willingness to suspend judgment while alternatives are explored (Facione 1990a; Ennis 1991; Halpern 1998).
• Trust in reason : Since distrust in the processes of reasoned inquiry will dissuade one from engaging in it, trust in them is an initiating critical thinking disposition (Facione 1990a, 25; Bailin et al. 1999b: 294; Facione, Facione, & Giancarlo 2001; Paul & Elder 2006). In reaction to an allegedly exclusive emphasis on reason in critical thinking theory and pedagogy, Thayer-Bacon (2000) argues that intuition, imagination, and emotion have important roles to play in an adequate conception of critical thinking that she calls “constructive thinking”. From her point of view, critical thinking requires trust not only in reason but also in intuition, imagination, and emotion.
• Seeking the truth : If one does not care about the truth but is content to stick with one’s initial bias on an issue, then one will not think critically about it. Seeking the truth is thus an initiating critical thinking disposition (Bailin et al. 1999b: 294; Facione, Facione, & Giancarlo 2001). A disposition to seek the truth is implicit in more specific critical thinking dispositions, such as trying to be well-informed, considering seriously points of view other than one’s own, looking for alternatives, suspending judgment when the evidence is insufficient, and adopting a position when the evidence supporting it is sufficient.

Some of the initiating dispositions, such as open-mindedness and willingness to suspend judgment, are also internal critical thinking dispositions, in the sense of mental habits or attitudes that contribute causally to doing a good job of critical thinking once one starts the process. But there are many other internal critical thinking dispositions. Some of them are parasitic on one’s conception of good thinking. For example, it is constitutive of good thinking about an issue to formulate the issue clearly and to maintain focus on it. For this purpose, one needs not only the corresponding ability but also the corresponding disposition. Ennis (1991: 8) describes it as the disposition “to determine and maintain focus on the conclusion or question”, Facione (1990a: 25) as “clarity in stating the question or concern”. Other internal dispositions are motivators to continue or adjust the critical thinking process, such as willingness to persist in a complex task and willingness to abandon nonproductive strategies in an attempt to self-correct (Halpern 1998: 452). For a list of identified internal critical thinking dispositions, see the Supplement on Internal Critical Thinking Dispositions .

Some theorists postulate skills, i.e., acquired abilities, as operative in critical thinking. It is not obvious, however, that a good mental act is the exercise of a generic acquired skill. Inferring an expected time of arrival, as in Transit , has some generic components but also uses non-generic subject-matter knowledge. Bailin et al. (1999a) argue against viewing critical thinking skills as generic and discrete, on the ground that skilled performance at a critical thinking task cannot be separated from knowledge of concepts and from domain-specific principles of good thinking. Talk of skills, they concede, is unproblematic if it means merely that a person with critical thinking skills is capable of intelligent performance.

Despite such scepticism, theorists of critical thinking have listed as general contributors to critical thinking what they variously call abilities (Glaser 1941; Ennis 1962, 1991), skills (Facione 1990a; Halpern 1998) or competencies (Fisher & Scriven 1997). Amalgamating these lists would produce a confusing and chaotic cornucopia of more than 50 possible educational objectives, with only partial overlap among them. It makes sense instead to try to understand the reasons for the multiplicity and diversity, and to make a selection according to one’s own reasons for singling out abilities to be developed in a critical thinking curriculum. Two reasons for diversity among lists of critical thinking abilities are the underlying conception of critical thinking and the envisaged educational level. Appraisal-only conceptions, for example, involve a different suite of abilities than constructive-only conceptions. Some lists, such as those in (Glaser 1941), are put forward as educational objectives for secondary school students, whereas others are proposed as objectives for college students (e.g., Facione 1990a).

The abilities described in the remaining paragraphs of this section emerge from reflection on the general abilities needed to do well the thinking activities identified in section 6 as components of the critical thinking process described in section 5 . The derivation of each collection of abilities is accompanied by citation of sources that list such abilities and of standardized tests that claim to test them.

Observational abilities : Careful and accurate observation sometimes requires specialist expertise and practice, as in the case of observing birds and observing accident scenes. However, there are general abilities of noticing what one’s senses are picking up from one’s environment and of being able to articulate clearly and accurately to oneself and others what one has observed. It helps in exercising them to be able to recognize and take into account factors that make one’s observation less trustworthy, such as prior framing of the situation, inadequate time, deficient senses, poor observation conditions, and the like. It helps as well to be skilled at taking steps to make one’s observation more trustworthy, such as moving closer to get a better look, measuring something three times and taking the average, and checking what one thinks one is observing with someone else who is in a good position to observe it. It also helps to be skilled at recognizing respects in which one’s report of one’s observation involves inference rather than direct observation, so that one can then consider whether the inference is justified. These abilities come into play as well when one thinks about whether and with what degree of confidence to accept an observation report, for example in the study of history or in a criminal investigation or in assessing news reports. Observational abilities show up in some lists of critical thinking abilities (Ennis 1962: 90; Facione 1990a: 16; Ennis 1991: 9). There are items testing a person’s ability to judge the credibility of observation reports in the Cornell Critical Thinking Tests, Levels X and Z (Ennis & Millman 1971; Ennis, Millman, & Tomko 1985, 2005). Norris and King (1983, 1985, 1990a, 1990b) is a test of ability to appraise observation reports.

Emotional abilities : The emotions that drive a critical thinking process are perplexity or puzzlement, a wish to resolve it, and satisfaction at achieving the desired resolution. Children experience these emotions at an early age, without being trained to do so. Education that takes critical thinking as a goal needs only to channel these emotions and to make sure not to stifle them. Collaborative critical thinking benefits from ability to recognize one’s own and others’ emotional commitments and reactions.

Questioning abilities : A critical thinking process needs transformation of an inchoate sense of perplexity into a clear question. Formulating a question well requires not building in questionable assumptions, not prejudging the issue, and using language that in context is unambiguous and precise enough (Ennis 1962: 97; 1991: 9).

Imaginative abilities : Thinking directed at finding the correct causal explanation of a general phenomenon or particular event requires an ability to imagine possible explanations. Thinking about what policy or plan of action to adopt requires generation of options and consideration of possible consequences of each option. Domain knowledge is required for such creative activity, but a general ability to imagine alternatives is helpful and can be nurtured so as to become easier, quicker, more extensive, and deeper (Dewey 1910: 34–39; 1933: 40–47). Facione (1990a) and Halpern (1998) include the ability to imagine alternatives as a critical thinking ability.

Inferential abilities : The ability to draw conclusions from given information, and to recognize with what degree of certainty one’s own or others’ conclusions follow, is universally recognized as a general critical thinking ability. All 11 examples in section 2 of this article include inferences, some from hypotheses or options (as in Transit , Ferryboat and Disorder ), others from something observed (as in Weather and Rash ). None of these inferences is formally valid. Rather, they are licensed by general, sometimes qualified substantive rules of inference (Toulmin 1958) that rest on domain knowledge—that a bus trip takes about the same time in each direction, that the terminal of a wireless telegraph would be located on the highest possible place, that sudden cooling is often followed by rain, that an allergic reaction to a sulfa drug generally shows up soon after one starts taking it. It is a matter of controversy to what extent the specialized ability to deduce conclusions from premisses using formal rules of inference is needed for critical thinking. Dewey (1933) locates logical forms in setting out the products of reflection rather than in the process of reflection. Ennis (1981a), on the other hand, maintains that a liberally-educated person should have the following abilities: to translate natural-language statements into statements using the standard logical operators, to use appropriately the language of necessary and sufficient conditions, to deal with argument forms and arguments containing symbols, to determine whether in virtue of an argument’s form its conclusion follows necessarily from its premisses, to reason with logically complex propositions, and to apply the rules and procedures of deductive logic. Inferential abilities are recognized as critical thinking abilities by Glaser (1941: 6), Facione (1990a: 9), Ennis (1991: 9), Fisher & Scriven (1997: 99, 111), and Halpern (1998: 452). Items testing inferential abilities constitute two of the five subtests of the Watson Glaser Critical Thinking Appraisal (Watson & Glaser 1980a, 1980b, 1994), two of the four sections in the Cornell Critical Thinking Test Level X (Ennis & Millman 1971; Ennis, Millman, & Tomko 1985, 2005), three of the seven sections in the Cornell Critical Thinking Test Level Z (Ennis & Millman 1971; Ennis, Millman, & Tomko 1985, 2005), 11 of the 34 items on Forms A and B of the California Critical Thinking Skills Test (Facione 1990b, 1992), and a high but variable proportion of the 25 selected-response questions in the Collegiate Learning Assessment (Council for Aid to Education 2017).

Experimenting abilities : Knowing how to design and execute an experiment is important not just in scientific research but also in everyday life, as in Rash . Dewey devoted a whole chapter of his How We Think (1910: 145–156; 1933: 190–202) to the superiority of experimentation over observation in advancing knowledge. Experimenting abilities come into play at one remove in appraising reports of scientific studies. Skill in designing and executing experiments includes the acknowledged abilities to appraise evidence (Glaser 1941: 6), to carry out experiments and to apply appropriate statistical inference techniques (Facione 1990a: 9), to judge inductions to an explanatory hypothesis (Ennis 1991: 9), and to recognize the need for an adequately large sample size (Halpern 1998). The Cornell Critical Thinking Test Level Z (Ennis & Millman 1971; Ennis, Millman, & Tomko 1985, 2005) includes four items (out of 52) on experimental design. The Collegiate Learning Assessment (Council for Aid to Education 2017) makes room for appraisal of study design in both its performance task and its selected-response questions.

Consulting abilities : Skill at consulting sources of information comes into play when one seeks information to help resolve a problem, as in Candidate . Ability to find and appraise information includes ability to gather and marshal pertinent information (Glaser 1941: 6), to judge whether a statement made by an alleged authority is acceptable (Ennis 1962: 84), to plan a search for desired information (Facione 1990a: 9), and to judge the credibility of a source (Ennis 1991: 9). Ability to judge the credibility of statements is tested by 24 items (out of 76) in the Cornell Critical Thinking Test Level X (Ennis & Millman 1971; Ennis, Millman, & Tomko 1985, 2005) and by four items (out of 52) in the Cornell Critical Thinking Test Level Z (Ennis & Millman 1971; Ennis, Millman, & Tomko 1985, 2005). The College Learning Assessment’s performance task requires evaluation of whether information in documents is credible or unreliable (Council for Aid to Education 2017).

Argument analysis abilities : The ability to identify and analyze arguments contributes to the process of surveying arguments on an issue in order to form one’s own reasoned judgment, as in Candidate . The ability to detect and analyze arguments is recognized as a critical thinking skill by Facione (1990a: 7–8), Ennis (1991: 9) and Halpern (1998). Five items (out of 34) on the California Critical Thinking Skills Test (Facione 1990b, 1992) test skill at argument analysis. The College Learning Assessment (Council for Aid to Education 2017) incorporates argument analysis in its selected-response tests of critical reading and evaluation and of critiquing an argument.

Judging skills and deciding skills : Skill at judging and deciding is skill at recognizing what judgment or decision the available evidence and argument supports, and with what degree of confidence. It is thus a component of the inferential skills already discussed.

Lists and tests of critical thinking abilities often include two more abilities: identifying assumptions and constructing and evaluating definitions.

In addition to dispositions and abilities, critical thinking needs knowledge: of critical thinking concepts, of critical thinking principles, and of the subject-matter of the thinking.

We can derive a short list of concepts whose understanding contributes to critical thinking from the critical thinking abilities described in the preceding section. Observational abilities require an understanding of the difference between observation and inference. Questioning abilities require an understanding of the concepts of ambiguity and vagueness. Inferential abilities require an understanding of the difference between conclusive and defeasible inference (traditionally, between deduction and induction), as well as of the difference between necessary and sufficient conditions. Experimenting abilities require an understanding of the concepts of hypothesis, null hypothesis, assumption and prediction, as well as of the concept of statistical significance and of its difference from importance. They also require an understanding of the difference between an experiment and an observational study, and in particular of the difference between a randomized controlled trial, a prospective correlational study and a retrospective (case-control) study. Argument analysis abilities require an understanding of the concepts of argument, premiss, assumption, conclusion and counter-consideration. Additional critical thinking concepts are proposed by Bailin et al. (1999b: 293), Fisher & Scriven (1997: 105–106), and Black (2012).

According to Glaser (1941: 25), ability to think critically requires knowledge of the methods of logical inquiry and reasoning. If we review the list of abilities in the preceding section, however, we can see that some of them can be acquired and exercised merely through practice, possibly guided in an educational setting, followed by feedback. Searching intelligently for a causal explanation of some phenomenon or event requires that one consider a full range of possible causal contributors, but it seems more important that one implements this principle in one’s practice than that one is able to articulate it. What is important is “operational knowledge” of the standards and principles of good thinking (Bailin et al. 1999b: 291–293). But the development of such critical thinking abilities as designing an experiment or constructing an operational definition can benefit from learning their underlying theory. Further, explicit knowledge of quirks of human thinking seems useful as a cautionary guide. Human memory is not just fallible about details, as people learn from their own experiences of misremembering, but is so malleable that a detailed, clear and vivid recollection of an event can be a total fabrication (Loftus 2017). People seek or interpret evidence in ways that are partial to their existing beliefs and expectations, often unconscious of their “confirmation bias” (Nickerson 1998). Not only are people subject to this and other cognitive biases (Kahneman 2011), of which they are typically unaware, but it may be counter-productive for one to make oneself aware of them and try consciously to counteract them or to counteract social biases such as racial or sexual stereotypes (Kenyon & Beaulac 2014). It is helpful to be aware of these facts and of the superior effectiveness of blocking the operation of biases—for example, by making an immediate record of one’s observations, refraining from forming a preliminary explanatory hypothesis, blind refereeing, double-blind randomized trials, and blind grading of students’ work.

Critical thinking about an issue requires substantive knowledge of the domain to which the issue belongs. Critical thinking abilities are not a magic elixir that can be applied to any issue whatever by somebody who has no knowledge of the facts relevant to exploring that issue. For example, the student in Bubbles needed to know that gases do not penetrate solid objects like a glass, that air expands when heated, that the volume of an enclosed gas varies directly with its temperature and inversely with its pressure, and that hot objects will spontaneously cool down to the ambient temperature of their surroundings unless kept hot by insulation or a source of heat. Critical thinkers thus need a rich fund of subject-matter knowledge relevant to the variety of situations they encounter. This fact is recognized in the inclusion among critical thinking dispositions of a concern to become and remain generally well informed.

Experimental educational interventions, with control groups, have shown that education can improve critical thinking skills and dispositions, as measured by standardized tests. For information about these tests, see the Supplement on Assessment .

What educational methods are most effective at developing the dispositions, abilities and knowledge of a critical thinker? Abrami et al. (2015) found that in the experimental and quasi-experimental studies that they analyzed dialogue, anchored instruction, and mentoring each increased the effectiveness of the educational intervention, and that they were most effective when combined. They also found that in these studies a combination of separate instruction in critical thinking with subject-matter instruction in which students are encouraged to think critically was more effective than either by itself. However, the difference was not statistically significant; that is, it might have arisen by chance.

Most of these studies lack the longitudinal follow-up required to determine whether the observed differential improvements in critical thinking abilities or dispositions continue over time, for example until high school or college graduation. For details on studies of methods of developing critical thinking skills and dispositions, see the Supplement on Educational Methods .

12. Controversies

Scholars have denied the generalizability of critical thinking abilities across subject domains, have alleged bias in critical thinking theory and pedagogy, and have investigated the relationship of critical thinking to other kinds of thinking.

McPeck (1981) attacked the thinking skills movement of the 1970s, including the critical thinking movement. He argued that there are no general thinking skills, since thinking is always thinking about some subject-matter. It is futile, he claimed, for schools and colleges to teach thinking as if it were a separate subject. Rather, teachers should lead their pupils to become autonomous thinkers by teaching school subjects in a way that brings out their cognitive structure and that encourages and rewards discussion and argument. As some of his critics (e.g., Paul 1985; Siegel 1985) pointed out, McPeck’s central argument needs elaboration, since it has obvious counter-examples in writing and speaking, for which (up to a certain level of complexity) there are teachable general abilities even though they are always about some subject-matter. To make his argument convincing, McPeck needs to explain how thinking differs from writing and speaking in a way that does not permit useful abstraction of its components from the subject-matters with which it deals. He has not done so. Nevertheless, his position that the dispositions and abilities of a critical thinker are best developed in the context of subject-matter instruction is shared by many theorists of critical thinking, including Dewey (1910, 1933), Glaser (1941), Passmore (1980), Weinstein (1990), and Bailin et al. (1999b).

McPeck’s challenge prompted reflection on the extent to which critical thinking is subject-specific. McPeck argued for a strong subject-specificity thesis, according to which it is a conceptual truth that all critical thinking abilities are specific to a subject. (He did not however extend his subject-specificity thesis to critical thinking dispositions. In particular, he took the disposition to suspend judgment in situations of cognitive dissonance to be a general disposition.) Conceptual subject-specificity is subject to obvious counter-examples, such as the general ability to recognize confusion of necessary and sufficient conditions. A more modest thesis, also endorsed by McPeck, is epistemological subject-specificity, according to which the norms of good thinking vary from one field to another. Epistemological subject-specificity clearly holds to a certain extent; for example, the principles in accordance with which one solves a differential equation are quite different from the principles in accordance with which one determines whether a painting is a genuine Picasso. But the thesis suffers, as Ennis (1989) points out, from vagueness of the concept of a field or subject and from the obvious existence of inter-field principles, however broadly the concept of a field is construed. For example, the principles of hypothetico-deductive reasoning hold for all the varied fields in which such reasoning occurs. A third kind of subject-specificity is empirical subject-specificity, according to which as a matter of empirically observable fact a person with the abilities and dispositions of a critical thinker in one area of investigation will not necessarily have them in another area of investigation.

The thesis of empirical subject-specificity raises the general problem of transfer. If critical thinking abilities and dispositions have to be developed independently in each school subject, how are they of any use in dealing with the problems of everyday life and the political and social issues of contemporary society, most of which do not fit into the framework of a traditional school subject? Proponents of empirical subject-specificity tend to argue that transfer is more likely to occur if there is critical thinking instruction in a variety of domains, with explicit attention to dispositions and abilities that cut across domains. But evidence for this claim is scanty. There is a need for well-designed empirical studies that investigate the conditions that make transfer more likely.

It is common ground in debates about the generality or subject-specificity of critical thinking dispositions and abilities that critical thinking about any topic requires background knowledge about the topic. For example, the most sophisticated understanding of the principles of hypothetico-deductive reasoning is of no help unless accompanied by some knowledge of what might be plausible explanations of some phenomenon under investigation.

Critics have objected to bias in the theory, pedagogy and practice of critical thinking. Commentators (e.g., Alston 1995; Ennis 1998) have noted that anyone who takes a position has a bias in the neutral sense of being inclined in one direction rather than others. The critics, however, are objecting to bias in the pejorative sense of an unjustified favoring of certain ways of knowing over others, frequently alleging that the unjustly favoured ways are those of a dominant sex or culture (Bailin 1995). These ways favour:

• reinforcement of egocentric and sociocentric biases over dialectical engagement with opposing world-views (Paul 1981, 1984; Warren 1998)
• distancing from the object of inquiry over closeness to it (Martin 1992; Thayer-Bacon 1992)
• indifference to the situation of others over care for them (Martin 1992)
• orientation to thought over orientation to action (Martin 1992)
• being reasonable over caring to understand people’s ideas (Thayer-Bacon 1993)
• being neutral and objective over being embodied and situated (Thayer-Bacon 1995a)
• doubting over believing (Thayer-Bacon 1995b)
• reason over emotion, imagination and intuition (Thayer-Bacon 2000)
• solitary thinking over collaborative thinking (Thayer-Bacon 2000)
• written and spoken assignments over other forms of expression (Alston 2001)
• attention to written and spoken communications over attention to human problems (Alston 2001)
• winning debates in the public sphere over making and understanding meaning (Alston 2001)

A common thread in this smorgasbord of accusations is dissatisfaction with focusing on the logical analysis and evaluation of reasoning and arguments. While these authors acknowledge that such analysis and evaluation is part of critical thinking and should be part of its conceptualization and pedagogy, they insist that it is only a part. Paul (1981), for example, bemoans the tendency of atomistic teaching of methods of analyzing and evaluating arguments to turn students into more able sophists, adept at finding fault with positions and arguments with which they disagree but even more entrenched in the egocentric and sociocentric biases with which they began. Martin (1992) and Thayer-Bacon (1992) cite with approval the self-reported intimacy with their subject-matter of leading researchers in biology and medicine, an intimacy that conflicts with the distancing allegedly recommended in standard conceptions and pedagogy of critical thinking. Thayer-Bacon (2000) contrasts the embodied and socially embedded learning of her elementary school students in a Montessori school, who used their imagination, intuition and emotions as well as their reason, with conceptions of critical thinking as

thinking that is used to critique arguments, offer justifications, and make judgments about what are the good reasons, or the right answers. (Thayer-Bacon 2000: 127–128)

Alston (2001) reports that her students in a women’s studies class were able to see the flaws in the Cinderella myth that pervades much romantic fiction but in their own romantic relationships still acted as if all failures were the woman’s fault and still accepted the notions of love at first sight and living happily ever after. Students, she writes, should

be able to connect their intellectual critique to a more affective, somatic, and ethical account of making risky choices that have sexist, racist, classist, familial, sexual, or other consequences for themselves and those both near and far… critical thinking that reads arguments, texts, or practices merely on the surface without connections to feeling/desiring/doing or action lacks an ethical depth that should infuse the difference between mere cognitive activity and something we want to call critical thinking. (Alston 2001: 34)

Some critics portray such biases as unfair to women. Thayer-Bacon (1992), for example, has charged modern critical thinking theory with being sexist, on the ground that it separates the self from the object and causes one to lose touch with one’s inner voice, and thus stigmatizes women, who (she asserts) link self to object and listen to their inner voice. Her charge does not imply that women as a group are on average less able than men to analyze and evaluate arguments. Facione (1990c) found no difference by sex in performance on his California Critical Thinking Skills Test. Kuhn (1991: 280–281) found no difference by sex in either the disposition or the competence to engage in argumentative thinking.

The critics propose a variety of remedies for the biases that they allege. In general, they do not propose to eliminate or downplay critical thinking as an educational goal. Rather, they propose to conceptualize critical thinking differently and to change its pedagogy accordingly. Their pedagogical proposals arise logically from their objections. They can be summarized as follows:

• Focus on argument networks with dialectical exchanges reflecting contesting points of view rather than on atomic arguments, so as to develop “strong sense” critical thinking that transcends egocentric and sociocentric biases (Paul 1981, 1984).
• Foster closeness to the subject-matter and feeling connected to others in order to inform a humane democracy (Martin 1992).
• Develop “constructive thinking” as a social activity in a community of physically embodied and socially embedded inquirers with personal voices who value not only reason but also imagination, intuition and emotion (Thayer-Bacon 2000).
• In developing critical thinking in school subjects, treat as important neither skills nor dispositions but opening worlds of meaning (Alston 2001).
• Attend to the development of critical thinking dispositions as well as skills, and adopt the “critical pedagogy” practised and advocated by Freire (1968 [1970]) and hooks (1994) (Dalgleish, Girard, & Davies 2017).

A common thread in these proposals is treatment of critical thinking as a social, interactive, personally engaged activity like that of a quilting bee or a barn-raising (Thayer-Bacon 2000) rather than as an individual, solitary, distanced activity symbolized by Rodin’s The Thinker . One can get a vivid description of education with the former type of goal from the writings of bell hooks (1994, 2010). Critical thinking for her is open-minded dialectical exchange across opposing standpoints and from multiple perspectives, a conception similar to Paul’s “strong sense” critical thinking (Paul 1981). She abandons the structure of domination in the traditional classroom. In an introductory course on black women writers, for example, she assigns students to write an autobiographical paragraph about an early racial memory, then to read it aloud as the others listen, thus affirming the uniqueness and value of each voice and creating a communal awareness of the diversity of the group’s experiences (hooks 1994: 84). Her “engaged pedagogy” is thus similar to the “freedom under guidance” implemented in John Dewey’s Laboratory School of Chicago in the late 1890s and early 1900s. It incorporates the dialogue, anchored instruction, and mentoring that Abrami (2015) found to be most effective in improving critical thinking skills and dispositions.

What is the relationship of critical thinking to problem solving, decision-making, higher-order thinking, creative thinking, and other recognized types of thinking? One’s answer to this question obviously depends on how one defines the terms used in the question. If critical thinking is conceived broadly to cover any careful thinking about any topic for any purpose, then problem solving and decision making will be kinds of critical thinking, if they are done carefully. Historically, ‘critical thinking’ and ‘problem solving’ were two names for the same thing. If critical thinking is conceived more narrowly as consisting solely of appraisal of intellectual products, then it will be disjoint with problem solving and decision making, which are constructive.

Bloom’s taxonomy of educational objectives used the phrase “intellectual abilities and skills” for what had been labeled “critical thinking” by some, “reflective thinking” by Dewey and others, and “problem solving” by still others (Bloom et al. 1956: 38). Thus, the so-called “higher-order thinking skills” at the taxonomy’s top levels of analysis, synthesis and evaluation are just critical thinking skills, although they do not come with general criteria for their assessment (Ennis 1981b). The revised version of Bloom’s taxonomy (Anderson et al. 2001) likewise treats critical thinking as cutting across those types of cognitive process that involve more than remembering (Anderson et al. 2001: 269–270). For details, see the Supplement on History .

As to creative thinking, it overlaps with critical thinking (Bailin 1987, 1988). Thinking about the explanation of some phenomenon or event, as in Ferryboat , requires creative imagination in constructing plausible explanatory hypotheses. Likewise, thinking about a policy question, as in Candidate , requires creativity in coming up with options. Conversely, creativity in any field needs to be balanced by critical appraisal of the draft painting or novel or mathematical theory.

28 Incredible Examples of Critical Thinkers (Past and Present!)

Looking for examples of critical thinkers? Check out this guide to discover 28 incredible critical thinkers from the past and present.

Danny Newman

In search for examples of critical thinkers? I hope this post helps!

American entrepreneur Henry Ford famously said :

“Thinking is the hardest work there is, which is probably the reason so few engage in it.”

Of course, all of us think! Heck, researchers estimate that the average adult makes about 35,000 decisions every single day – all of which require a degree of thought.

No, it’s more likely that Henry Ford was talking about the type of thinking that critical thinkers do.

But what is critical thinking, exactly? Who are some examples of critical thinkers from the past and in modern society?

And what can we learn from them?

Let’s find out.

First up, what is critical thinking? The next section should help with the meaning of critical thinking…

What Is Critical Thinking?

Critical thinking describes a scientific attitude of mind with the goal of reflective thought. It includes perceiving a problem, making an effort to solve it, and reaching a conclusion that’s supported by data.

Fun fact: The term itself was first used in the 1930s by the American education reformist John Dewey (more on him later).

Here are some examples of critical thinking in action:

• A triage doctor analyses different cases and decides which patient to treat first
• An architect evaluates different materials and decides which best fits a construction project
• A parent mediates an argument between their children, listening to both sides of the story before reaching a decision
• A business owner reads customer feedback forms and uses the information to create a new training plan for employees
• A lawyer reviews evidence to determine whether to pursue the case or settle out of court
• A professional boxer steps into the ring and evaluates the strengths and weaknesses of his opponent

As you can see, critical thinking applies not just to scientific theory and research but to every aspect of life.

It’s no wonder that employers value critical thinking as an essential soft skill in the workplace.

Next up: some of the major critical thinkers from history…

Past Examples of Critical Thinkers

The term ‘critical thinking’ might be a modern invention, but history is full of brilliant people who used these principles long before we had a name for it.

Here’s a rundown of major critical thinkers from history:

1. Confucius (6th century BC)

Confucius lived over 2,500 years ago in ancient China, but he’s still considered to be one of the most critical thinkers in human history.

Among his famous ancient texts about philosophy, he’s also credited with the original Golden Rule : “Do not do to others what you do not want to be done to you.”

2. Socrates (5th century BC)

One of the most famous Greek philosophers, Socrates challenged the common people to think for themselves and question… well, pretty much everything!

He suggested that even the best leaders were at risk of becoming irrational and making poor decisions, which might seem obvious today, but was a radical concept at the time.

3. Plato (5th century BC)

Socrates taught many students, but none of them were as influential as Plato.

He’s best remembered for founding The Academy – the ancient Greek centre for learning and philosophy, as well as his teachings on justice, equality, and beauty.

4. Aristotle (4th century BC)

Socrates taught Plato, and Plato taught Aristotle — one of the greatest students ever to study at The Academy.

Aristotle is best known for his theories about life, death, and the immortality of the soul, as well as his contemplations about the universe, nature, and creation.

5. Jesus (1st century CE)

The founder of Christianity and, depending on your beliefs, one of the most influential people to ever live, Jesus’ teachings focused on love, faith, and the Kingdom of God.

In his famous Sermon on the Mount, he also offered insightful advice on such subjects as honesty, integrity, fidelity, and spirituality.

6. Abu Nasr Al-Farabi (870-950)

Persian linguist, philosopher, and intellectual Abu Nasr Al-Farabi is called “The Second Teacher” (behind Aristotle) and is credited with introducing Greek philosophy to the Muslim world.

He’s also remembered for his contributions to mathematics, physics, music, ethics, and politics.

7. Saint Thomas Aquinas (1224-1274)

Born in medieval Italy, Saint Thomas Aquinas is recognised by the Roman Catholic Church as its most influential theologian and philosopher.

He expressed many then-radical ideas about God, spirituality, and the nature of truth, but he welcomed criticism and opposing viewpoints and championed fact-based reasoning.

8. Galileo Galilei (1564-1642)

Major advancements in physics, motion, mathematics, astronomy, the scientific method — you name it, Galileo gave it to us .

Many of his discoveries caused an uproar among the staunch religious circles of his day, but his personal motto was “a defender of truth in the face of ignorance.”

9. Rene Descartes (1596–1650)

French scientist, philosopher, and mathematician Rene Descartes is best remembered for his statement, “I think, therefore I am.”

He wrote extensively about the human mind and the senses, as well as our ability to accurately perceive and judge situations.

10. Sir Isaac Newton (1642–1727)

If there was one culminating figure from the 17th century Scientific Revolution, Sir Isaac Newton claims the title.

He was renowned for rigorously testing each of his theories, which led to the foundations of everything we now know about gravity, physical optics, and the laws of motion.

11. Benjamin Franklin (1706–1790)

Colonial America produced one of the greatest critical thinkers of all time — Benjamin Franklin. Printer, publisher, writer, inventor, scientist, and statesman, some of his most significant inventions include the lightning rod, bifocal glasses, swim fins, and the urinary catheter.

Another example of people from past with Critical thinking skills is Charles Darwin…

12. Charles Darwin (1809-1882)

English-born Charles Darwin is synonymous with his scientific theory of evolution, which shook the religious foundations of his day.

He was the first to suggest that humans and animals share a common ancestor and is best known for his research in the Galapagos Islands as well as his book The Origin of the Species .

13. Sarah Margaret Fuller (1810-1850)

American activist Sarah Margaret Fuller was well ahead of her time, challenging the traditional role of women in education, society, and employment.

She’s best known for her landmark book, Woman in the Nineteenth Century , as well as for being the first woman ever allowed to use the Harvard College library.

14. George Bernard Shaw (1856-1950)

Playwright, literary critic, Nobel Prize winner, and socialist propagandist, Irish-born George Bernard Shaw revolutionised the world of comedic drama.

His writing was deeply philosophical, focusing on social tensions at the time, and he drew criticism for being a devout pacifist and antiwar activist during the two World Wars.

15. John Dewey (1859–1952)

The first to coin the term ‘critical thinking’ in the world of education, American John Dewey believed that social reform needed to start in our schools.

He pioneered the concept of inquiry-based learning, which modern educators continue to use in schools and universities around the world.

16. Marie Curie (1867-1934)

Polish-born French physicist Marie Curie was the first woman to win a Nobel Prize and the only woman to win Nobel Prizes in two different fields (physics and chemistry).

She was one of the pioneers in the field of radioactivity and laid the way for our modern x-ray machines and various cancer treatments.

17. Albert Einstein (1879–1955)

Perhaps one of the greatest minds of all time, German-born Albert Einstein is synonymous with the world of physics.

He developed the theory of relativity and received the Nobel Prize in 1921 for his work on the photoelectric effect and electromagnetic radiation.

18. Edwin Hubble (1889-1953)

American astronomer Edwin Hubble wasn’t content with looking up at the stars — he wanted to understand the world beyond our planet (and even our galaxy).

He not only discovered galaxies beyond the Milky Way but also proved that the universe is expanding.

It’s no wonder they named the revolutionary Hubble Space Telescope after him!

Hunting for critical thinking examples from modern times? Here they are…

Modern Examples of Critical Thinking

Our journey through history has been fascinating, but what about modern times?

Here are more examples of critical thinkers from the 20th and 21st centuries.

19. Simone de Beauvoir (1908-1986)

A bold and even radical feminist, French author Simone de Beauvoir wasn’t afraid to challenge society’s view of the sexes.

Her book The Second Sex heralded gender equality and women’s individuality, paving the way for every modern women’s rights movement of the 20th century.

20. Noah Chomsky (born in 1928)

Regarded as the father of modern linguistics, US-born Avram Noah Chomsky started what’s now known as the “cognitive revolution.”

He’s best known for his work in the fields of language and cognitive psychology, with the view that language is uniquely human (and biologically based).

He’s also a political dissident who speaks out about US politics, foreign policies, and international culture.

21. Maya Angelou (1928–2014)

Famed author of I Know Why the Caged Bird Sings , American author Maya Angelou is best known for her writings that explore racism, economics, and sexual oppression.

She was also highly active during the American civil rights movement and spoke out fearlessly alongside other activists like Martin Luther King Jr and Malcolm X.

Familiar with Martin Luther King, Jr? He is included on our list of modern examples of critical thinking…

22. Martin Luther King, Jr. (1929-1968)

Leader of the civil rights movement that led to the end of racial segregation in America, Martin Luther King Jr was fearless in his nonviolent pursuit of equality.

He was awarded the Nobel Peace Prize in 1964 before sadly being assassinated in 1968.

23. Alasdair MacIntyre (born in 1929)

Scottish philosopher Alasdair MacIntyre is regarded as one of the greatest moral thinkers and activists of the 20th century.

He’s written extensively on the subjects of political philosophy, ethics, and theology and is best known for his book After Virtue.

His viewpoints range from traditional Marxism and Catholicism to Neo-Aristotelian theories.

24. Dian Fossey (1932-1985)

American zoologist and conservationist Dian Fossey spent decades in Africa and became the world’s leading expert on mountain gorillas.

She’s best known for her book Gorillas in the Mist and her courageous public battle against poachers.

Sadly, she was murdered by an unknown assailant (likely the poachers she struggled against) in Rwanda in 1985.

25. Amartya Sen (born in 1933)

Economist Amartya Sen has dedicated his life to solving the problems of poverty, famine, and economic disparity in his home country of India (and beyond).

He’s worked extensively on identifying and mitigating the causes of famine, as well as developing a more sophisticated system for measuring poverty.

In 1998 he won the Nobel Prize in Economic Sciences.

26. Stanislav Petrov (1939-2017)

He may not wear a superhero cape, but this man actually saved the planet from nuclear war.

On September 26, 1983, Soviet officer Stanislav Petrov saw a report of an incoming American missile strike.

Luckily for the world, Petrov used his critical thinking skills to determine the report was false and halt the nuclear counter strike, saving an estimated 2 billion lives in the process!

27. Stephen Hawking (1942–2018)

Few critical thinkers have impacted the world scientifically, socially, and culturally as much as Stephen Hawking .

Despite his lifelong battle with Lou Gehrig’s disease, Hawking’s work on theoretical physics, quantum mechanics, and the space-time continuum forever changed the world of science.

28. Elon Musk (born in 1971)

PayPal. SpaceX. Tesla. Twitter. Behind virtually every major scientific advancement and revolution of the 21st century, one name stands behind it — South Africa’s own Elon Musk .

He’s nowhere near finished, either, with projects such as the Boring Company (a tunnelling startup) and Neuralink (a brain-computer interface technology firm) also in the pipeline.

Harness Your Own Critical Thinking Skills

As we’ve discussed, critical thinking is hardly a modern development.

From early thinkers like Confucius and Socrates to the most brilliant minds today, these examples of critical thinkers have contributed untold wisdom to our society.

No, you may not singlehandedly halt a nuclear missile strike, but you can harness the power of critical thinking for yourself. Make it your personal goal to work on your critical thinking skills and you’re sure to experience success in all aspects of life!

What else do you need to succeed? How about a healthy dose of self-confidence?
