Difference Between Action Research and Case Study

Main difference – action research vs case study.

Research is the careful study of a given field or problem in order to discover new facts or principles. Action research and case study are two types of research, which are mainly used in the field of social sciences and humanities. The main difference between action research and case study is their purpose; an action research study aims to solve an immediate problem whereas a case study aims to provide an in-depth analysis of a situation or case over a long period of time.

What is Action Research

Action research is a type of a research study that is initiated to solve an immediate problem. It may involve a variety of analytical, investigative and evaluative research methods designed to diagnose and solve problems. It has been defined as “a disciplined process of inquiry conducted by and for those taking the action. The primary reason for engaging in action research is to assist the “actor” in improving and/or refining his or her actions” (Sagor, 2000). This type of research is typically used in the field of education. Action research studies are generally conductors by educators, who also act as participants.

Here, an individual researcher or a group of researchers identify a problem, examine its causes and try to arrive at a solution to the problem. The action research process is as follows.

Action Research Process

• Identify a problem to research
• Clarify theories
• Identify research questions
• Collect data on the problem
• Organise, analyse, and interpret the data
• Create a plan to address the problem
• Implement the above-mentioned plan
• Evaluate the results of the actions taken

The above process will keep repeating. Action research is also known as cycle of inquiry or cycle of action since it follows a specific process that is repeated over time.

What is a Case Study

A case study is basically an in-depth examination of a particular event, situation or an individual. It is a type of research that is designed to explore and understand complex issues; however, it involves detailed contextual analysis of only a limited number of events or situations. It has been defined as “an empirical inquiry that investigates a contemporary phenomenon within its real-life context; when the boundaries between phenomenon and context are not clearly evident; and in which multiple sources of evidence are used.” (Yin, 1984)

Case studies are used in a variety of fields, but fields like sociology and education seem to use them the most. They can be used to probe into community-based problems such as illiteracy, unemployment, poverty, and drug addiction. 

Case studies involve both quantitative and qualitative data and allow the researchers to see beyond statistical results and understand human conditions. Furthermore, case studies can be classified into three categories, known as exploratory, descriptive and explanatory case studies.

However, case studies are also criticised since the study of a limited number of events or cases cannot easily establish generality or reliability of the findings. The process of a case study is generally as follows:

Case Study Process

• Identifying and defining the research questions
• Selecting the cases and deciding techniques for data collection and analysis
• Collecting data in the field
• Evaluating and analysing the data
• Preparing the report

Action Research : Action research is a type of a research study that is initiated to solve an immediate problem.

Case Study : Case study is an in-depth analysis of a particular event or case over a long period of time.                         

Action Research : Action research involves solving a problem.

Case Study : Case studies involve observing and analysing a situation.

Action Research : Action research studies are mainly used in the field of education.

Case Study : Case studies are used in many fields; they can be specially used with community problems such as unemployment, poverty, etc.

Action Research : Action research always involve providing a solution to a problem.

Case Study : Case studies do not provide a solution to a problem.

Participants

Action Research : Researchers can also act as participants of the research.

Case Study : Researchers generally don’t take part in the research study.

Definition and Introduction

Case analysis is a problem-based teaching and learning method that involves critically analyzing complex scenarios within an organizational setting for the purpose of placing the student in a “real world” situation and applying reflection and critical thinking skills to contemplate appropriate solutions, decisions, or recommended courses of action. It is considered a more effective teaching technique than in-class role playing or simulation activities. The analytical process is often guided by questions provided by the instructor that ask students to contemplate relationships between the facts and critical incidents described in the case.

Cases generally include both descriptive and statistical elements and rely on students applying abductive reasoning to develop and argue for preferred or best outcomes [i.e., case scenarios rarely have a single correct or perfect answer based on the evidence provided]. Rather than emphasizing theories or concepts, case analysis assignments emphasize building a bridge of relevancy between abstract thinking and practical application and, by so doing, teaches the value of both within a specific area of professional practice.

Given this, the purpose of a case analysis paper is to present a structured and logically organized format for analyzing the case situation. It can be assigned to students individually or as a small group assignment and it may include an in-class presentation component. Case analysis is predominately taught in economics and business-related courses, but it is also a method of teaching and learning found in other applied social sciences disciplines, such as, social work, public relations, education, journalism, and public administration.

How to Approach Writing a Case Analysis Paper

The organization and structure of a case analysis paper can vary depending on the organizational setting, the situation, and how your professor wants you to approach the assignment. Nevertheless, preparing to write a case analysis paper involves several important steps. As Hawes notes, a case analysis assignment “...is useful in developing the ability to get to the heart of a problem, analyze it thoroughly, and to indicate the appropriate solution as well as how it should be implemented” [p.48]. This statement encapsulates how you should approach preparing to write a case analysis paper.

Before you begin to write your paper, consider the following analytical procedures:

• Review the case to get an overview of the situation . A case can be only a few pages in length, however, it is most often very lengthy and contains a significant amount of detailed background information and statistics, with multilayered descriptions of the scenario, the roles and behaviors of various stakeholder groups, and situational events. Therefore, a quick reading of the case will help you gain an overall sense of the situation and illuminate the types of issues and problems that you will need to address in your paper. If your professor has provided questions intended to help frame your analysis, use them to guide your initial reading of the case.
• Read the case thoroughly . After gaining a general overview of the case, carefully read the content again with the purpose of understanding key circumstances, events, and behaviors among stakeholder groups. Look for information or data that appears contradictory, extraneous, or misleading. At this point, you should be taking notes as you read because this will help you develop a general outline of your paper. The aim is to obtain a complete understanding of the situation so that you can begin contemplating tentative answers to any questions your professor has provided or, if they have not provided, developing answers to your own questions about the case scenario and its connection to the course readings,lectures, and class discussions.
• Determine key stakeholder groups, issues, and events and the relationships they all have to each other . As you analyze the content, pay particular attention to identifying individuals, groups, or organizations described in the case and identify evidence of any problems or issues of concern that impact the situation in a negative way. Other things to look for include identifying any assumptions being made by or about each stakeholder, potential biased explanations or actions, explicit demands or ultimatums , and the underlying concerns that motivate these behaviors among stakeholders. The goal at this stage is to develop a comprehensive understanding of the situational and behavioral dynamics of the case and the explicit and implicit consequences of each of these actions.
• Identify the core problems . The next step in most case analysis assignments is to discern what the core [i.e., most damaging, detrimental, injurious] problems are within the organizational setting and to determine their implications. The purpose at this stage of preparing to write your analysis paper is to distinguish between the symptoms of core problems and the core problems themselves and to decide which of these must be addressed immediately and which problems do not appear critical but may escalate over time. Identify evidence from the case to support your decisions by determining what information or data is essential to addressing the core problems and what information is not relevant or is misleading.
• Explore alternative solutions . As noted, case analysis scenarios rarely have only one correct answer. Therefore, it is important to keep in mind that the process of analyzing the case and diagnosing core problems, while based on evidence, is a subjective process open to various avenues of interpretation. This means that you must consider alternative solutions or courses of action by critically examining strengths and weaknesses, risk factors, and the differences between short and long-term solutions. For each possible solution or course of action, consider the consequences they may have related to their implementation and how these recommendations might lead to new problems. Also, consider thinking about your recommended solutions or courses of action in relation to issues of fairness, equity, and inclusion.
• Decide on a final set of recommendations . The last stage in preparing to write a case analysis paper is to assert an opinion or viewpoint about the recommendations needed to help resolve the core problems as you see them and to make a persuasive argument for supporting this point of view. Prepare a clear rationale for your recommendations based on examining each element of your analysis. Anticipate possible obstacles that could derail their implementation. Consider any counter-arguments that could be made concerning the validity of your recommended actions. Finally, describe a set of criteria and measurable indicators that could be applied to evaluating the effectiveness of your implementation plan.

Use these steps as the framework for writing your paper. Remember that the more detailed you are in taking notes as you critically examine each element of the case, the more information you will have to draw from when you begin to write. This will save you time.

NOTE : If the process of preparing to write a case analysis paper is assigned as a student group project, consider having each member of the group analyze a specific element of the case, including drafting answers to the corresponding questions used by your professor to frame the analysis. This will help make the analytical process more efficient and ensure that the distribution of work is equitable. This can also facilitate who is responsible for drafting each part of the final case analysis paper and, if applicable, the in-class presentation.

Structure and Writing Style

A case analysis paper should be detailed, concise, persuasive, clearly written, and professional in tone and in the use of language . As with other forms of college-level academic writing, declarative statements that convey information, provide a fact, or offer an explanation or any recommended courses of action should be based on evidence. If allowed by your professor, any external sources used to support your analysis, such as course readings, should be properly cited under a list of references. The organization and structure of case analysis papers can vary depending on your professor’s preferred format, but its structure generally follows the steps used for analyzing the case.

Introduction

The introduction should provide a succinct but thorough descriptive overview of the main facts, issues, and core problems of the case . The introduction should also include a brief summary of the most relevant details about the situation and organizational setting. This includes defining the theoretical framework or conceptual model on which any questions were used to frame your analysis.

Following the rules of most college-level research papers, the introduction should then inform the reader how the paper will be organized. This includes describing the major sections of the paper and the order in which they will be presented. Unless you are told to do so by your professor, you do not need to preview your final recommendations in the introduction. U nlike most college-level research papers , the introduction does not include a statement about the significance of your findings because a case analysis assignment does not involve contributing new knowledge about a research problem.

Background Analysis

Background analysis can vary depending on any guiding questions provided by your professor and the underlying concept or theory that the case is based upon. In general, however, this section of your paper should focus on:

• Providing an overarching analysis of problems identified from the case scenario, including identifying events that stakeholders find challenging or troublesome,
• Identifying assumptions made by each stakeholder and any apparent biases they may exhibit,
• Describing any demands or claims made by or forced upon key stakeholders, and
• Highlighting any issues of concern or complaints expressed by stakeholders in response to those demands or claims.

These aspects of the case are often in the form of behavioral responses expressed by individuals or groups within the organizational setting. However, note that problems in a case situation can also be reflected in data [or the lack thereof] and in the decision-making, operational, cultural, or institutional structure of the organization. Additionally, demands or claims can be either internal and external to the organization [e.g., a case analysis involving a president considering arms sales to Saudi Arabia could include managing internal demands from White House advisors as well as demands from members of Congress].

Throughout this section, present all relevant evidence from the case that supports your analysis. Do not simply claim there is a problem, an assumption, a demand, or a concern; tell the reader what part of the case informed how you identified these background elements.

Identification of Problems

In most case analysis assignments, there are problems, and then there are problems . Each problem can reflect a multitude of underlying symptoms that are detrimental to the interests of the organization. The purpose of identifying problems is to teach students how to differentiate between problems that vary in severity, impact, and relative importance. Given this, problems can be described in three general forms: those that must be addressed immediately, those that should be addressed but the impact is not severe, and those that do not require immediate attention and can be set aside for the time being.

All of the problems you identify from the case should be identified in this section of your paper, with a description based on evidence explaining the problem variances. If the assignment asks you to conduct research to further support your assessment of the problems, include this in your explanation. Remember to cite those sources in a list of references. Use specific evidence from the case and apply appropriate concepts, theories, and models discussed in class or in relevant course readings to highlight and explain the key problems [or problem] that you believe must be solved immediately and describe the underlying symptoms and why they are so critical.

Alternative Solutions

This section is where you provide specific, realistic, and evidence-based solutions to the problems you have identified and make recommendations about how to alleviate the underlying symptomatic conditions impacting the organizational setting. For each solution, you must explain why it was chosen and provide clear evidence to support your reasoning. This can include, for example, course readings and class discussions as well as research resources, such as, books, journal articles, research reports, or government documents. In some cases, your professor may encourage you to include personal, anecdotal experiences as evidence to support why you chose a particular solution or set of solutions. Using anecdotal evidence helps promote reflective thinking about the process of determining what qualifies as a core problem and relevant solution .

Throughout this part of the paper, keep in mind the entire array of problems that must be addressed and describe in detail the solutions that might be implemented to resolve these problems.

Recommended Courses of Action

In some case analysis assignments, your professor may ask you to combine the alternative solutions section with your recommended courses of action. However, it is important to know the difference between the two. A solution refers to the answer to a problem. A course of action refers to a procedure or deliberate sequence of activities adopted to proactively confront a situation, often in the context of accomplishing a goal. In this context, proposed courses of action are based on your analysis of alternative solutions. Your description and justification for pursuing each course of action should represent the overall plan for implementing your recommendations.

For each course of action, you need to explain the rationale for your recommendation in a way that confronts challenges, explains risks, and anticipates any counter-arguments from stakeholders. Do this by considering the strengths and weaknesses of each course of action framed in relation to how the action is expected to resolve the core problems presented, the possible ways the action may affect remaining problems, and how the recommended action will be perceived by each stakeholder.

In addition, you should describe the criteria needed to measure how well the implementation of these actions is working and explain which individuals or groups are responsible for ensuring your recommendations are successful. In addition, always consider the law of unintended consequences. Outline difficulties that may arise in implementing each course of action and describe how implementing the proposed courses of action [either individually or collectively] may lead to new problems [both large and small].

Throughout this section, you must consider the costs and benefits of recommending your courses of action in relation to uncertainties or missing information and the negative consequences of success.

The conclusion should be brief and introspective. Unlike a research paper, the conclusion in a case analysis paper does not include a summary of key findings and their significance, a statement about how the study contributed to existing knowledge, or indicate opportunities for future research.

Begin by synthesizing the core problems presented in the case and the relevance of your recommended solutions. This can include an explanation of what you have learned about the case in the context of your answers to the questions provided by your professor. The conclusion is also where you link what you learned from analyzing the case with the course readings or class discussions. This can further demonstrate your understanding of the relationships between the practical case situation and the theoretical and abstract content of assigned readings and other course content.

Problems to Avoid

The literature on case analysis assignments often includes examples of difficulties students have with applying methods of critical analysis and effectively reporting the results of their assessment of the situation. A common reason cited by scholars is that the application of this type of teaching and learning method is limited to applied fields of social and behavioral sciences and, as a result, writing a case analysis paper can be unfamiliar to most students entering college.

After you have drafted your paper, proofread the narrative flow and revise any of these common errors:

• Unnecessary detail in the background section . The background section should highlight the essential elements of the case based on your analysis. Focus on summarizing the facts and highlighting the key factors that become relevant in the other sections of the paper by eliminating any unnecessary information.
• Analysis relies too much on opinion . Your analysis is interpretive, but the narrative must be connected clearly to evidence from the case and any models and theories discussed in class or in course readings. Any positions or arguments you make should be supported by evidence.
• Analysis does not focus on the most important elements of the case . Your paper should provide a thorough overview of the case. However, the analysis should focus on providing evidence about what you identify are the key events, stakeholders, issues, and problems. Emphasize what you identify as the most critical aspects of the case to be developed throughout your analysis. Be thorough but succinct.
• Writing is too descriptive . A paper with too much descriptive information detracts from your analysis of the complexities of the case situation. Questions about what happened, where, when, and by whom should only be included as essential information leading to your examination of questions related to why, how, and for what purpose.
• Inadequate definition of a core problem and associated symptoms . A common error found in case analysis papers is recommending a solution or course of action without adequately defining or demonstrating that you understand the problem. Make sure you have clearly described the problem and its impact and scope within the organizational setting. Ensure that you have adequately described the root causes w hen describing the symptoms of the problem.
• Recommendations lack specificity . Identify any use of vague statements and indeterminate terminology, such as, “A particular experience” or “a large increase to the budget.” These statements cannot be measured and, as a result, there is no way to evaluate their successful implementation. Provide specific data and use direct language in describing recommended actions.
• Unrealistic, exaggerated, or unattainable recommendations . Review your recommendations to ensure that they are based on the situational facts of the case. Your recommended solutions and courses of action must be based on realistic assumptions and fit within the constraints of the situation. Also note that the case scenario has already happened, therefore, any speculation or arguments about what could have occurred if the circumstances were different should be revised or eliminated.

Writing Tip

Ca se Study and Case Analysis Are Not the Same!

Confusion often exists between what it means to write a paper that uses a case study research design and writing a paper that analyzes a case; they are two different types of approaches to learning in the social and behavioral sciences. Professors as well as educational researchers contribute to this confusion because they often use the term "case study" when describing the subject of analysis for a case analysis paper. But you are not studying a case for the purpose of generating a comprehensive, multi-faceted understanding of a research problem. R ather, you are critically analyzing a specific scenario to argue logically for recommended solutions and courses of action that lead to optimal outcomes applicable to professional practice.

To avoid any confusion, here are twelve characteristics that delineate the differences between writing a paper using the case study research method and writing a case analysis paper:

• Case study is a method of in-depth research and rigorous inquiry ; case analysis is a reliable method of teaching and learning . A case study is a modality of research that investigates a phenomenon for the purpose of creating new knowledge, solving a problem, or testing a hypothesis using empirical evidence derived from the case being studied. Often, the results are used to generalize about a larger population or within a wider context. The writing adheres to the traditional standards of a scholarly research study. A case analysis is a pedagogical tool used to teach students how to reflect and think critically about a practical, real-life problem in an organizational setting.
• The researcher is responsible for identifying the case to study; a case analysis is assigned by your professor . As the researcher, you choose the case study to investigate in support of obtaining new knowledge and understanding about the research problem. The case in a case analysis assignment is almost always provided, and sometimes written, by your professor and either given to every student in class to analyze individually or to a small group of students, or students select a case to analyze from a predetermined list.
• A case study is indeterminate and boundless; a case analysis is predetermined and confined . A case study can be almost anything [see item 9 below] as long as it relates directly to examining the research problem. This relationship is the only limit to what a researcher can choose as the subject of their case study. The content of a case analysis is determined by your professor and its parameters are well-defined and limited to elucidating insights of practical value applied to practice.
• Case study is fact-based and describes actual events or situations; case analysis can be entirely fictional or adapted from an actual situation . The entire content of a case study must be grounded in reality to be a valid subject of investigation in an empirical research study. A case analysis only needs to set the stage for critically examining a situation in practice and, therefore, can be entirely fictional or adapted, all or in-part, from an actual situation.
• Research using a case study method must adhere to principles of intellectual honesty and academic integrity; a case analysis scenario can include misleading or false information . A case study paper must report research objectively and factually to ensure that any findings are understood to be logically correct and trustworthy. A case analysis scenario may include misleading or false information intended to deliberately distract from the central issues of the case. The purpose is to teach students how to sort through conflicting or useless information in order to come up with the preferred solution. Any use of misleading or false information in academic research is considered unethical.
• Case study is linked to a research problem; case analysis is linked to a practical situation or scenario . In the social sciences, the subject of an investigation is most often framed as a problem that must be researched in order to generate new knowledge leading to a solution. Case analysis narratives are grounded in real life scenarios for the purpose of examining the realities of decision-making behavior and processes within organizational settings. A case analysis assignments include a problem or set of problems to be analyzed. However, the goal is centered around the act of identifying and evaluating courses of action leading to best possible outcomes.
• The purpose of a case study is to create new knowledge through research; the purpose of a case analysis is to teach new understanding . Case studies are a choice of methodological design intended to create new knowledge about resolving a research problem. A case analysis is a mode of teaching and learning intended to create new understanding and an awareness of uncertainty applied to practice through acts of critical thinking and reflection.
• A case study seeks to identify the best possible solution to a research problem; case analysis can have an indeterminate set of solutions or outcomes . Your role in studying a case is to discover the most logical, evidence-based ways to address a research problem. A case analysis assignment rarely has a single correct answer because one of the goals is to force students to confront the real life dynamics of uncertainly, ambiguity, and missing or conflicting information within professional practice. Under these conditions, a perfect outcome or solution almost never exists.
• Case study is unbounded and relies on gathering external information; case analysis is a self-contained subject of analysis . The scope of a case study chosen as a method of research is bounded. However, the researcher is free to gather whatever information and data is necessary to investigate its relevance to understanding the research problem. For a case analysis assignment, your professor will often ask you to examine solutions or recommended courses of action based solely on facts and information from the case.
• Case study can be a person, place, object, issue, event, condition, or phenomenon; a case analysis is a carefully constructed synopsis of events, situations, and behaviors . The research problem dictates the type of case being studied and, therefore, the design can encompass almost anything tangible as long as it fulfills the objective of generating new knowledge and understanding. A case analysis is in the form of a narrative containing descriptions of facts, situations, processes, rules, and behaviors within a particular setting and under a specific set of circumstances.
• Case study can represent an open-ended subject of inquiry; a case analysis is a narrative about something that has happened in the past . A case study is not restricted by time and can encompass an event or issue with no temporal limit or end. For example, the current war in Ukraine can be used as a case study of how medical personnel help civilians during a large military conflict, even though circumstances around this event are still evolving. A case analysis can be used to elicit critical thinking about current or future situations in practice, but the case itself is a narrative about something finite and that has taken place in the past.
• Multiple case studies can be used in a research study; case analysis involves examining a single scenario . Case study research can use two or more cases to examine a problem, often for the purpose of conducting a comparative investigation intended to discover hidden relationships, document emerging trends, or determine variations among different examples. A case analysis assignment typically describes a stand-alone, self-contained situation and any comparisons among cases are conducted during in-class discussions and/or student presentations.

Action research or case study?

When planning for a practice-based enquiry or small-scale study you will most often be confronted with the choice between an action research or case study approach. Strictly speaking, there are many approaches to enquiries, but for practical reasons the action research or case study approaches are amongst the most popular for teacher-researchers.

Your decision for one or the other approach must be well justified and to this end you must consult research methodology literature. However, in the following there will be a simplified exploration of the two approaches to get you started.

What is action research? Action research should be considered as a way of life in the classroom. As a reflective practitioner you will observe what happens in your class and then identify an issue or problem that you need to address. After consulting relevant literature you will then formulate a new approach or intervention, which you carry out in your classroom. Once you have worked with this intervention you will reflect and reconsider its effectiveness and impact and the cycle can start again. For a practice-based enquiry you may go through several cycles or through one cycle only. The advantage of the action research is that it naturally develops from your teaching practice and that it addresses real issues within your classroom. Typical critique of action researches would be that they are not rigorous or systematic enough.

What is case study? A case study is more difficult to understand because it can be a method as well as a methodology. Here we only look at case studies for their methodological function. If you want to learn more about a specific issue or you want to explore a particular problem or occurrence, then the case study is for you. The description of what makes a “case” differs in various research methodology publications, but generally speaking a “case” can refer to a group of people, a specific person or issue, a collective of ideas. The advantage of a case study is that you get to know the status quo in all its facets and so you gain a deep insight into your field of study. Common critique of the case study approach is that it is so specialised and specific to the context of the research that generalisability is lost. Sometimes it is also said that the mere description of a status quo is not practical for teachers because there are no changes. My argument would be that detailed knowlegde of what happens in your classroom or school can lead to recommendations for future practice. It is just that you do not enter a cyclical approach of evaluating and revisiting your suggested changes.

Action research or case study? Both approaches have their benefits and limitations within the realm of practice-based enquiries. The choice therefore depends on what it is that you want to find out. Are you planning to introduce a new teaching strategy or changes or interventions with some or all of your pupils? Or are you trying to explore a specific topic? The former would be a justification for action research, whereas the latter hints at a case study. You must be guided by your research focus, your research question or hypothesis and by the research methodology publications you consult.

Table of contents

Types of action research, action research models, examples of action research, action research vs. traditional research, advantages and disadvantages of action research, frequently asked questions about action research.

There are 2 common types of action research: participatory action research and practical action research.

• Participatory action research emphasises that participants should be members of the community being studied, empowering those directly affected by outcomes of said research. In this method, participants are effectively co-researchers, with their lived experiences considered formative to the research process.
• Practical action research focuses more on how research is conducted and is designed to address and solve specific issues.

Both types of action research are more focused on increasing the capacity and ability of future practitioners than contributing to a theoretical body of knowledge.

Action research is often reflected in 3 action research models: operational (sometimes called technical), collaboration, and critical reflection.

• Operational (or technical) action research is usually visualised like a spiral following a series of steps, such as “planning → acting → observing → reflecting.”
• Collaboration action research is more community-based, focused on building a network of similar individuals (e.g., college professors in a given geographic area) and compiling learnings from iterated feedback cycles.
• Critical reflection action research serves to contextualise systemic processes that are already ongoing (e.g., working retroactively to analyse existing school systems by questioning why certain practices were put into place and developed the way they did).

Action research is often used in fields like education because of its iterative and flexible style.

After the information was collected, the students were asked where they thought ramps or other accessibility measures would be best utilised, and the suggestions were sent to school administrators. Example: Practical action research Science teachers at your city’s high school have been witnessing a year-over-year decline in standardised test scores in chemistry. In seeking the source of this issue, they studied how concepts are taught in depth, focusing on the methods, tools, and approaches used by each teacher.

Action research differs sharply from other types of research in that it seeks to produce actionable processes over the course of the research rather than contributing to existing knowledge or drawing conclusions from datasets. In this way, action research is formative , not summative , and is conducted in an ongoing, iterative way.

As such, action research is different in purpose, context, and significance and is a good fit for those seeking to implement systemic change.

Action research comes with advantages and disadvantages.

• Action research is highly adaptable , allowing researchers to mould their analysis to their individual needs and implement practical individual-level changes.
• Action research provides an immediate and actionable path forward for solving entrenched issues, rather than suggesting complicated, longer-term solutions rooted in complex data.
• Done correctly, action research can be very empowering , informing social change and allowing participants to effect that change in ways meaningful to their communities.

Disadvantages

• Due to their flexibility, action research studies are plagued by very limited generalisability  and are very difficult to replicate . They are often not considered theoretically rigorous due to the power the researcher holds in drawing conclusions.
• Action research can be complicated to structure in an ethical manner . Participants may feel pressured to participate or to participate in a certain way.
• Action research is at high risk for research biases such as selection bias , social desirability bias , or other types of cognitive biases .

Action research is conducted in order to solve a particular issue immediately, while case studies are often conducted over a longer period of time and focus more on observing and analyzing a particular ongoing phenomenon.

Action research is focused on solving a problem or informing individual and community-based knowledge in a way that impacts teaching, learning, and other related processes. It is less focused on contributing theoretical input, instead producing actionable input.

Action research is particularly popular with educators as a form of systematic inquiry because it prioritizes reflection and bridges the gap between theory and practice. Educators are able to simultaneously investigate an issue as they solve it, and the method is very iterative and flexible.

A cycle of inquiry is another name for action research . It is usually visualized in a spiral shape following a series of steps, such as “planning → acting → observing → reflecting.”

Action Research vs Case Study : Know the Key Difference Between Two Qualitative Research Methods

A research method is nothing but a technique of inquiry which proceeds from the underlying philosophical assumptions to research design and data collection. Specific research methods imply various assumptions, skills, research practices and the choice of research approach influences the manner in which the data is collected. 

Among various research methods, the most popular and widely used design is qualitative research. This design consists of many philosophical perspectives and various research methods, of which includes  action research and case study research.

Action Research

Action research is a type of qualitative research, which is adopted by the researcher in order to solve the immediate problem arisen during the particular course of time. It is a way which bridges the gap between educational theory and professional practice by improvising their current practices. This type of research helps the researcher to improvise its current practices and is applied for researching into issues.

The main purpose of action research is to learn through action leading to personal or professional development. It enables researchers not only to suggest appropriate lines of action but also to investigate the actual effects of such actions. Further, this type of research is situation based, is useful in problem-solving and deals with individuals or groups with a common purpose of improving practice.

Action research is conducted in classrooms and organisations, where the practitioner will observe what happens and then identify an issue or problem that they need to address. Further according to the issues, ways to solve the problems are identified and applied by the practitioner in their practices. This approach is applied using qualitative designs to explain what is happening and to understand the effects of some educational intervention. 

Further, this research helps in addressing practical problems and in generating knowledge to produce change.

Methods used in collecting data in action research are:

• Observing individuals or groups
• Using audio and videotape recording
• Using structured or semi-structured interviews
• Taking field notes
• Conducting surveys or questionnaires

Case study research is more of a qualitative method of research where there is an in-depth study of an individual or a group of individuals. It explores a contemporary prodigy within its real-life context and provides an organised way of observing the events, collecting data, analysing information, and reporting the results.

Further, the case study method focuses on the description or exploration of a particular phenomenon, rather than identifying the cause and effect. This method includes both quantitative and qualitative data and allow the researchers to see beyond statistical results and understand human conditions like illiteracy, poverty, etc. 

Case studies is categorised in 3 ways: exploratory, explanatory and descriptive.

Exploratory case studies explore any event in the data which serves as a point of interest to the researcher. For example, a researcher conducting an exploratory case study on an individual’s learning process may ask questions, such as, “Does a student use any strategies when he learns a text?” This type of question results in further examination of the phenomenon. 

On the other hand, the explanatory case study examines the data carefully and explains the phenomenon occurred in the data.

Descriptive case studies describe the natural phenomena which occur within the data. For example, what are the strategies used by the learner?, etc. 

Case studies are useful as they help the researcher to analyse the data at a small level but there is a  tendency for the researcher to be biased at the time of interpreting the data. 

Methods used in collecting the data in the case study method are:

• Interviews, transcript analyses or protocol 
• An exploration of artifacts.
• A review of documents and archived record
• Direct participant observations
• Field studies

Difference between action research and case study

At times people confuse the action research method with that of case study as both are a little bit similar to each other. But in real-time, they are quite different.

• Action research focuses on solving the immediate problem whereas, case studies focus on a particular phenomenon for a longer period of time.
• Action research method emphasis on solving the problem whereas case study method emphasis on observing, analysing and interpreting a particular phenomenon or scenario.
• Researcher at times can also be the part of the action research whereas in case study researcher don’t take part in the research.

Now that you know the difference between the two approaches, choose the method accordingly and accomplish your research.

1. Action Research : Action Research is a type of qualitative research. As the name suggests it is more action oriented in order to solve an immediate problem. Action research helps the researcher to improvise its current practices and is applied for researching into issues. It aims to learn through action leading to personal or professional development means focuses on improving and/or refining actions. This type research generally used in field of education to bridge the gap between educational theory and professional practice by improvising their current practices. This helps in observing the problem and identifying the cause and then addressing the issue so mainly it is more focused on immediate addressing to practical problems and in generating knowledge to produce change.

2. Case Study : Case study research refers to an in-depth examination of a particular event or individual or a group of individuals. It is more of a qualitative method of research where it understand complex issues by deeply observing and analyzing the event or situation by collecting and reporting the data related to the event or situation. Case study research is more towards description rather than immediate cause and effect finding. Case study is categorized into three ways i.e., exploratory, explanatory and descriptive based on research method. These studies involve both quantitative and qualitative data. This type of research can be used to address community-based problems like illiteracy, unemployment, poverty, and drug addiction.

Case Study vs. Research

What's the difference.

Case study and research are both methods used in academic and professional settings to gather information and gain insights. However, they differ in their approach and purpose. A case study is an in-depth analysis of a specific individual, group, or situation, aiming to understand the unique characteristics and dynamics involved. It often involves qualitative data collection methods such as interviews, observations, and document analysis. On the other hand, research is a systematic investigation conducted to generate new knowledge or validate existing theories. It typically involves a larger sample size and employs quantitative data collection methods such as surveys, experiments, or statistical analysis. While case studies provide detailed and context-specific information, research aims to generalize findings to a broader population.

Further Detail

Introduction.

When it comes to conducting studies and gathering information, researchers have various methods at their disposal. Two commonly used approaches are case study and research. While both methods aim to explore and understand a particular subject, they differ in their approach, scope, and the type of data they collect. In this article, we will delve into the attributes of case study and research, highlighting their similarities and differences.

A case study is an in-depth analysis of a specific individual, group, event, or phenomenon. It involves a detailed examination of a particular case to gain insights into its unique characteristics, context, and dynamics. Case studies often employ multiple sources of data, such as interviews, observations, and documents, to provide a comprehensive understanding of the subject under investigation.

One of the key attributes of a case study is its focus on a specific case, which allows researchers to explore complex and nuanced aspects of the subject. By examining a single case in detail, researchers can uncover rich and detailed information that may not be possible with broader research methods. Case studies are particularly useful when studying rare or unique phenomena, as they provide an opportunity to deeply analyze and understand them.

Furthermore, case studies often employ qualitative research methods, emphasizing the collection of non-numerical data. This qualitative approach allows researchers to capture the subjective experiences, perspectives, and motivations of the individuals or groups involved in the case. By using open-ended interviews and observations, researchers can gather rich and detailed data that provides a holistic view of the subject.

However, it is important to note that case studies have limitations. Due to their focus on a specific case, the findings may not be easily generalized to a larger population or context. The small sample size and unique characteristics of the case may limit the generalizability of the results. Additionally, the subjective nature of qualitative data collection in case studies may introduce bias or interpretation challenges.

Research, on the other hand, is a systematic investigation aimed at discovering new knowledge or validating existing theories. It involves the collection, analysis, and interpretation of data to answer research questions or test hypotheses. Research can be conducted using various methods, including surveys, experiments, and statistical analysis, depending on the nature of the study.

One of the primary attributes of research is its emphasis on generating generalizable knowledge. By using representative samples and statistical techniques, researchers aim to draw conclusions that can be applied to a larger population or context. This allows for the identification of patterns, trends, and relationships that can inform theories, policies, or practices.

Research often employs quantitative methods, focusing on the collection of numerical data that can be analyzed using statistical techniques. Surveys, experiments, and statistical analysis allow researchers to measure variables, establish correlations, and test hypotheses. This objective approach provides a level of objectivity and replicability that is crucial for scientific inquiry.

However, research also has its limitations. The focus on generalizability may sometimes sacrifice the depth and richness of understanding that case studies offer. The reliance on quantitative data may overlook important qualitative aspects of the subject, such as individual experiences or contextual factors. Additionally, the controlled nature of research settings may not fully capture the complexity and dynamics of real-world situations.

Similarities

Despite their differences, case studies and research share some common attributes. Both methods aim to gather information and generate knowledge about a particular subject. They require careful planning, data collection, analysis, and interpretation. Both case studies and research contribute to the advancement of knowledge in their respective fields.

Furthermore, both case studies and research can be used in various disciplines, including social sciences, psychology, business, and healthcare. They provide valuable insights and contribute to evidence-based decision-making. Whether it is understanding the impact of a new treatment, exploring consumer behavior, or investigating social phenomena, both case studies and research play a crucial role in expanding our understanding of the world.

In conclusion, case study and research are two distinct yet valuable approaches to studying and understanding a subject. Case studies offer an in-depth analysis of a specific case, providing rich and detailed information that may not be possible with broader research methods. On the other hand, research aims to generate generalizable knowledge by using representative samples and quantitative methods. While case studies emphasize qualitative data collection, research focuses on quantitative analysis. Both methods have their strengths and limitations, and their choice depends on the research objectives, scope, and context. By utilizing the appropriate method, researchers can gain valuable insights and contribute to the advancement of knowledge in their respective fields.

• Policy & Compliance
• Clinical Trials

NIH Definition of Clinical Trial Case Studies

The case studies provided below are designed to help you identify whether your study would be considered by NIH to be a clinical trial. Expect the case studies and related guidance to evolve over the upcoming year. For continuity and ease of reference, case studies will retain their original numbering and will not be renumbered if cases are revised or removed.

The simplified case studies apply the following four questions to determine whether NIH would consider the research study to be a clinical trial:

• Does the study involve human participants?
• Are the participants prospectively assigned to an intervention?
• Is the study designed to evaluate the effect of the intervention on the participants?
• Is the effect being evaluated a health-related biomedical or behavioral outcome?

If the answer to all four questions is “yes,” then the clinical study would be considered a clinical trial according to the NIH definition.

At a glance

One Health is a collaborative, multisectoral, and transdisciplinary approach — working at the local, regional, national, and global levels — with the goal of achieving optimal health outcomes recognizing the interconnection between people, animals, plants, and their shared environment.

What is One Health?

One Health is an approach that recognizes that the health of people is closely connected to the health of animals and our shared environment. One Health is not new, but it has become more important in recent years. This is because many factors have changed interactions between people, animals, plants, and our environment.

• Human populations are growing and expanding into new geographic areas. As a result, more people live in close contact with wild and domestic animals, both livestock and pets. Animals play an important role in our lives, whether for food, fiber, livelihoods, travel, sport, education, or companionship. Close contact with animals and their environments provides more opportunities for diseases to pass between animals and people.
• The earth has experienced changes in climate and land use, such as deforestation and intensive farming practices. Disruptions in environmental conditions and habitats can provide new opportunities for diseases to pass to animals.
• The movement of people, animals, and animal products has increased from international travel and trade. As a result, diseases can spread quickly across borders and around the globe.

These changes have led to the spread of existing or known (endemic) and new or emerging zoonotic diseases , which are diseases that can spread between animals and people. Every year, millions of people and animals around the world are affected by zoonotic diseases. Examples of zoonotic diseases include:

• Salmonella infection
• West Nile virus infection
• Q Fever (Coxiella burnetii)
• Brucellosis
• Lyme disease

Similar to humans, animals are also at risk of getting sick from some diseases and environmental hazards. Because of this, they can sometimes serve as early warning signs of potential human illness. For example, birds often die of West Nile virus before people in the same area get sick with West Nile virus infection.

One Health Fact Sheet‎

What are common one health issues.

One Health issues include emerging, re-emerging, and endemic zoonotic diseases, neglected tropical diseases, vector-borne diseases, antimicrobial resistance , food safety and food security, environmental contamination, climate change and other health threats shared by people, animals, and the environment. For example:

• Antimicrobial-resistant germs can quickly spread through communities, the food supply, healthcare facilities, and the environment (soil, water), making it harder to treat certain infections in animals and people.
• Vector-borne diseases are on the rise with warmer temperatures and expanded mosquito and tick habitats.
• Diseases in food animals can threaten supplies, livelihoods, and economies.
• The human-animal bond can help improve mental well-being.
• Contamination of water used for drinking, recreation, and more can make people and animals sick.

Even the fields of chronic disease, mental health, injury, occupational health, and noncommunicable diseases can benefit from a One Health approach involving collaboration across disciplines and sectors.

How does a One Health approach work?

One Health is gaining recognition in the United States and globally as an effective way to fight health issues at the human-animal-environment interface, including zoonotic diseases. CDC uses a One Health approach by involving experts in human, animal, environmental health, and other relevant disciplines and sectors in monitoring and controlling public health threats and to learn about how diseases spread among people, animals, plants, and the environment.

Successful public health interventions require the cooperation of human, animal, and environmental health partners. Professionals in human health (doctors, nurses, public health practitioners, epidemiologists), animal health (veterinarians, paraprofessionals, agricultural workers), environment (ecologists, wildlife experts), and other areas of expertise need to communicate, collaborate on, and coordinate activities. Other relevant players in a One Health approach could include law enforcement, policymakers, agriculture, communities, and even pet owners. No one person, organization, or sector can address issues at the animal-human-environment interface alone.

The One Health approach can:

• Prevent outbreaks of zoonotic disease in animals and people.
• Improve food safety and security.
• Reduce antimicrobial-resistant infections and improve human and animal health.
• Protect global health security.
• Protect biodiversity and conservation.

By promoting collaboration across all sectors, a One Health approach can achieve the best health outcomes for people, animals, and plants in a shared environment.

The state of diversity in global private markets: 2023

Over the course of 2022, the global private markets industry experienced a slowdown in fundraising and deal making because of rising interest rates and other factors. Despite the rocky year, private equity and alternative investments (hereafter PE) and alternative investments remain significant in the global economy. The industry now manages $11.7 trillion in assets, up from $8.0 trillion the previous year. 1 “ McKinsey Global Private Markets Review: Private markets turn down the volume ,” McKinsey, March 21, 2023. The financial power of PE reinforces the importance of understanding the composition of its talent, particularly the professionals who decide how this capital is deployed.

About the authors

This report is a collaborative effort by Pontus Averstad , Fredrik Dahlqvist , Eitan Lefkowitz, Alexandra Nee , Gary Pinshaw , David Quigley,  and Mohammed Shafi, representing views from McKinsey’s Private Equity & Principal Investors Practice.

Building on McKinsey’s 2022 report , this year’s report examines the diversity of talent in PE firms, which we will refer to simply as PE firms. Specifically, we examine the gender breakdown in every region in our study and look at ethnicity and race in the United States and Canada (for more on the research and analysis, see sidebar “About the study”).

We are excited to invite Private Equity/Alternative Investing firms and Institutional Investors to participate in McKinsey & Company’s State of Diversity in Global Private Markets 2024 study! This annual study is the largest and most comprehensive study of diversity in private market firms globally.

This year’s report centers on the following core research objectives:

• understand the current state of gender diversity globally, and ethnic and racial diversity in the US and Canada, for the PE industry—specifically, which types of firms are leading and lagging on diverse talent
• how institutional investors influence the representation of diverse talent at PE firms, and the extent to which diversity matters to them
• highlighting the specific challenges facing different minority groups and identifying actions that can increase the diversity of talent in PE firms

About the study

In our second annual report, we build on the insights and findings from our inaugural report in 2022, as well as on prior McKinsey research on diversity in the workplace. This research explores diversity, equity, and inclusion (DEI) in the global private-markets industry, with a focus on private equity and alternative investment firms (PE) and institutional investors. We aim to make this the largest study of gender diversity and ethnic and racial diversity in the global private markets industry.

This year’s survey covers 66 discrete PE firms and institutional investors around the world. We also conducted interviews with several industry leaders to supplement the survey data we received from their firms. Participating firms directly employ more than 60,000 people globally and range from megafirms with more than $100 billion in assets under management (AUM) to smaller funds with less than $5 billion in AUM. Collectively, participating PE firms manage more than $6 trillion, and participating institutional investors manage more than $5 trillion in AUM.

Given the limitations of data collection, this report largely focuses on gender diversity globally and ethnic and racial diversity in private market firms with offices in the United States and Canada. We recognize there are several other categories that contribute to employee diversity and hope to broaden the categories we examine in future research as private market firms collect more diversity data on their employee base.

This report finds encouraging signs of progress in recent years. Diversity on investment committees (ICs) has ticked up, and the reporting of diversity metrics to institutional investors continues to grow.

Still, gaps remain, particularly regarding gender diversity in senior investing roles and uneven rates of progress for different ethnic and racial groups across roles and regions, and types of firms. Given the current pace of progress, it will be several decades before the PE industry achieves gender parity at the principal and managing-director levels.

Given the current pace of progress, it will be several decades before the PE industry achieves gender parity at the principal and managing-director levels.

A global view on gender diversity in private equity and alternative investing

There is a popular assumption that PE is dominated by men, but the evidence reveals a more nuanced reality. As we noted last year, PE firms have almost achieved gender parity globally at the entry level. At the end of 2022, 48 percent of all entry-level roles in PE were held by women.

Job levels in private equity

The language we use to classify jobs in private equity (PE) has not changed from last year's. The six levels we identify apply to PE jobs in investing, operational, and other noninvesting functions. For most of these levels, we include multiple possible job titles. In descending order of seniority, the roles are as follows:

L1. C-level executives or fund heads. We refer to this level as the C-level or C-suite.

L2. Managing directors or partners. We refer to jobs at this level as managing directors.

L3. Principals, directors, or senior vice presidents. We refer to jobs at this level as principals.

L4. Vice presidents or senior managers. We refer to jobs at this level as VPs.

L5. Associates or managers. We refer to jobs at this level as associates.

L6. Entry level roles.

For the sake of simplicity, we will refer to each level with only one title.

However, women in PE are still underrepresented in leadership positions, with only 20 percent representation in managing-director roles (for more on job levels, see sidebar “Job levels in private equity”). As Kelley King, senior vice president and chief DEI officer at HarbourVest, explained, “Identifying and attracting early-career diverse talent is not as challenging as finding later-career talent. As you ascend higher in the organization, the more patient and intentional firms need to be to reap the benefits of their DEI efforts.”

Women are well represented in most noninvesting roles, but gender parity remains distant in investing and operating roles

Disaggregating the data into investing, operating, and other noninvesting roles (the latter of which we will refer to as noninvesting roles) reveals that women hold only 33 percent of entry-level investing roles, compared with 44 percent of operating roles and 59 percent of noninvesting roles at that level. Women are also underrepresented at the managing-director level (L2), with only 15 percent of managing-director-level investing roles (Exhibit 1).

Women in PE have made modest gains in investing roles over the course of 2022. The share of C-suite roles held by women globally increased by 3.5 percentage points over the past year to 17 percent at the end of 2022. Similarly, women’s representation in post-MBA investing associate (L5) roles improved by three percentage points. However, gender diversity at the managing-director level remained constant.

Women in PE are slightly less represented in operating roles than in investing roles, with women holding only 25 percent of all operating roles. Notably, women in operations have achieved gender parity at the associate level (L5), with 52 percent of roles. However, gender diversity undergoes a steep decline at higher levels, with women holding just 21 percent of managing-director-level (L2) operating jobs.

Progress is generally cause for optimism, but if the pace of progress doesn’t accelerate, the path to gender parity in the industry will be long. At the current rate of progress, reaching gender parity in investing roles at the managing-director level (L2) would take more than six decades. Achieving gender parity at the principal level (L3) would take more than three decades (Exhibit 2).

While these numbers are sobering, the outlook is significantly brighter at the entry level. Based on current figures, the industry could reach gender parity at the analyst level (L6) and associate level (L5) within the next decade.

At the current rate of progress, reaching gender parity in investing roles at the managing-director level (L2) would take more than six decades.

Promotion rates: Women in investing face a longer road

In demanding PE careers, women find themselves navigating a longer route to reach the same milestones as their male colleagues. At almost every level, women in investing roles are promoted at significantly lower rates than men. Globally, men in investing roles are about 50 percent more likely, on average, to be promoted than their female colleagues, a trend that persists across all levels in investing roles (Exhibit 3).

The largest gap affects promotions into the principal level (L3), with men 2.75 times more likely than women to be promoted. One contributor to this disparity may be limited sponsorship and mentorship for women at the vice president (VP) level. As the head of talent for a North American PE fund put it, “At that [middle] level is where we find a number of ethnic minorities and women who have really felt like the levels they are at have a sticky floor. They found that it’s really hard to get that next promotion. They feel left out. They haven’t received the kind of mentorship and the kind of apprenticeship that they’re really going to need or the sponsorship to get promoted.”

The road to meaningful progress will likely be long. However, there’s a bright spot: the promotion gap at the managing-director level (L2) shrank in 2022.

Globally, men in investing roles are about 50 percent more likely, on average, to be promoted than their female colleagues.

Significant differences in representation between leading and lagging firms

Some firms have made noteworthy strides on the diversity of their talent pool, so much so that the industry’s global average of women in 15 percent of investing managing-director roles looks paltry by comparison. Leading firms had women in 45 percent of managing-director (L2) roles as the end of 2022. These firms also had significantly higher proportions of women at every level and overall had women in 38 percent of their investing roles, compared with the global average of 25 percent.

Interestingly, firms that were leaders in gender diversity (as indicated by relatively high proportions of women in managing-director roles) also retained women at higher rates than the industry average. However, firms that lagged on gender diversity showed significantly higher attrition in 2022 among women in investing. These firms in our sample did not have women in managing-director (L2) investing roles and had only 17 percent women in investing roles overall compared to the 25 percent global benchmark. Furthermore, these firms’ attrition rates for women in investing were 1.7 times higher, at 27 percent, than the global average over the course of 2022 (Exhibit 4).

For investing roles, our findings suggest a correlation between the representation of women at the top and higher overall gender representation, as well as between lack of women at the top and their ability to retain women at all levels of investing roles.

Our findings on gender diversity over time also highlight the feasibility of substantial progress when decision makers deploy effective strategies. Indeed, the results of our study show that not all PE firms are equal when it comes to cultures that support diverse talent.

Different regions have different timelines to gender parity

The timelines to achieving gender parity vary by region. For instance, despite advances, Europe still faces significant challenges related to women’s representation at senior levels. At its current pace, Europe would require more than six decades to reach gender parity at senior levels.

By contrast, based on the rate of recent progress, the Americas are the furthest from achieving gender parity at middle and junior levels for investing roles. The situation is notably different in the Asia–Pacific region, which has done the most to close the gender gap at middle and senior levels recently (Exhibit 5).

A concerning trend has emerged over the past two years: gender representation has seen a minor decrease in the Asia–Pacific region at the associate level (L5). Although this decline starts from a relatively high base, it indicates the need for ongoing efforts to maintain a diverse talent pipeline that can help the industry achieve gender parity.

Ethnic and racial diversity in private equity

Consistent with our past findings, ethnic and racial minorities in PE face similar underrepresentation as women. At nearly every level, investing roles have lower ethnic and racial diversity than noninvesting and operating-partner roles.

Our research data from the United States and Canada shows that ethnic and racial minorities represent only 20 percent of managing-director-level investing professionals (Exhibit 6). For context, people who identify as ethnic and racial minorities account for 30 percent of the Canadian population and 41 percent of the US population. 2 “QuickFacts: United States population estimates,” US Census Bureau, July 1, 2022; “The Canadian census: A rich portrait of the country's religious and ethnocultural diversity,” Statistics Canada, October 26, 2022. However, we found positive progress in ethnic and racial diversity in ICs in 2022. Ethnic and racial minorities represented 18 percent of investment committee members, nearly matching the ethnic and racial diversity of managing directors (L2) that year.

The improvement in the diversity of talent in investment committees over the course of 2022 may be the result of new requirements for PE firms to disclose C-suite- and investment-committee-level diversity data to prospective investors. The chief HR officer of a midsize PE firm headquartered in North America referred to this as “a standard part of the due diligence questionnaire these days.”

Investment professionals who identify as White held 70 percent of all investing roles and 80 percent of managing-director roles. As of 2022, White men made up the majority of White PE professionals at 79 percent, with 86 percent at the managing-director level. By contrast, women who identify as ethnic and racial minorities were the least represented group among investment professionals across all levels. White professionals lead promotion rates into every level except principal (L3). The difference in promotion is most drastic at the managing-director level (L2), in which White professionals were more than 2.3 times more likely to be promoted than any other race or ethnicity. And once they make it to the top, White professionals has the lowest rates of attrition, trailing only Hispanic and Latino investing professionals in attrition rates at the principal level (L3) and managing-director level (L2).

Firms with more ethnic and racial diversity at the top tend to have more-diverse talent pools

Not all PE firms have struggled to attract and develop talent from ethnic and racial minorities. Leading firms have reached or are nearing representative levels, with 42 percent of investing talent identifying as ethnic or racial minorities, compared with 30 percent of the Canadian population and 41 percent of the US population.

Lagging firms, on the other hand, have almost no ethnic and racial diversity at senior levels. These challenges at the top are reflected throughout the organization, with only 23 percent of investing professionals at lagging firms identifying as ethnic and racial minorities.

Firms that lead the industry in ethnic and racial diversity have demonstrated that significant progress is possible, but there is still work to be done to make PE offices in the United States and Canada more representative. Black and Hispanic professionals remain underrepresented, even at firms that lead on ethnic and racial diversity. Fourteen percent of the US population is Black, and 19 percent is Hispanic, 3 “QuickFacts: United States population estimates,” US Census Bureau, July 1, 2022. but even at leading firms, only 8 percent of managing directors are Black, and 9 percent are Hispanic.

Institutional investors are asking more about DEI metrics

When making funding decisions, institutional investors increasingly take PE firms’ DEI practices into account.

Institutional investors are broadening their view of DEI beyond the investment team and institutional investors now increasingly ask about DEI metrics within portfolio companies and their boards (Exhibit 7). This growing interest from institutional investors has encouraged PE firms to systematically track and report on these metrics, fueling momentum toward diversity and inclusion in the industry. As a partner at a North American PE fund put it, “Data requests from LPs [limited partners] on diversity and inclusion have gone from zero in the 2000s to everyone asking about it today.”

Notably, some institutional investors track PE firms’ year-over-year improvements in diversity and inclusion as part of their DEI assessments. Forward-looking institutional investors have started to move beyond simply tracking DEI metrics and are beginning to set minimum thresholds on some metrics. For instance, one institutional investor in our sample requires PE firms to meet minimum racial- and gender-diversity thresholds before the institutional investor considers making an investment.

Structural barriers for PE firms owned by ethnic and racial minorities and women

Institutional investors are continuing to gather data on diversity inclusion. But are their allocations consistent with their stated priorities?

Institutional investors that participated in last year’s study said they would be willing to give more capital to more-diverse deal teams. 4 “QuickFacts: United States population estimates,” US Census Bureau, July 1, 2022. However, institutional investors face challenges in making that promise a reality. As of 2021, PE firms owned by ethnic and racial minorities and women managed only 6 percent of total AUM in PE. 5 Knight diversity of asset managers research series: Industry , Knight Foundation, December 2021. If diversity is high on institutional investors’ priority list, why don’t minority-owned funds receive more capital?

The hurdle for minority- and women-owned funds is not their track record or the investing team’s experience. The challenges are structural and make it harder for institutional investors to allocate to these firms. For instance, compared with their competitors, minority- and women-owned firms are smaller and newer on average. In the current macroeconomic environment, institutional investors are relying more on existing long-term relationships with general partners to weather the cycle, leaving even fewer slots for these firms to compete over. To connect with these firms, institutional investors would have to go through brokers or adjust their minimum allocation rules to directly invest in smaller raises.

As institutional investors continue to shape the future of private equity, their influence will be vital in ensuring that DEI remains top of mind. Through thoughtful capital allocation and continued focus on DEI metrics, institutional investors have the power to drive meaningful change in the sector, making PE more inclusive, more diverse, and ultimately more successful.

From aspiration to action: Tangible steps toward a more diverse future

Our study highlights that to achieve a more diverse, equitable, and inclusive industry, firms require additional internal actions and practices as well as external pressures. Strategies to retain and promote diverse talent within PE firms would need to coexist with a collaborative commitment from institutional investors to demand DEI metrics and support women- and minority-owned funds. Our discussion focuses on specific actions and regional considerations that can accelerate the path to greater diversity of talent within investing roles in private markets globally.

Must-haves: A focus on retaining diverse talent and practices that accelerate the path to equity

PE firms have made initial progress in diversifying their entry-level talent pipelines. To establish a more inclusive culture and move toward gender parity, those efforts would need to extend to the senior ranks. It’s important for practices that promote diversity and inclusion to be embedded in every level of the organization. DEI should not be seen as just a recruitment initiative.

Key practices to implement include the following:

• analyzing attrition and promotion rates by gender, ethnicity, and race where possible, along with other measures of diversity, to shed light on firms’ effectiveness in retaining and promoting diverse talent
• developing intentional sponsorship and mentorship programs that can guide diverse talent, especially in midlevel roles
• establishing employee resource groups (ERGs) for diverse talent to offer safe spaces for interaction, discussion, and mutual support
• implementing more flexible HR policies, such as remote work, to cast a wider net for talent and improve inclusion for professionals from diverse backgrounds
• hosting unconscious-bias and conscious-inclusion training to minimize the impact of unconscious prejudices on decision-making processes
• creating intentional on-ramps and off-ramps for employees as they transition to and from parental leave or extended time off to help normalize these journeys

These initiatives go beyond recruitment and are crucial in building an inclusive environment that not only welcomes diverse team members but also enables them to flourish and ascend the ranks. By committing to these practices, PE firms can nurture diversity throughout their organizations, from the entry level to top leadership.

The road toward equity in PE is long, but a continued focus on actions that could accelerate progress can put the industry’s aspirations within reach. Institutional investors can continue to reinforce the industry’s commitment to DEI, and by acting on these commitments, PE firms can hone the edge that comes with diversity.

Cultural Relativity and Acceptance of Embryonic Stem Cell Research

Article sidebar.

Main Article Content

There is a debate about the ethical implications of using human embryos in stem cell research, which can be influenced by cultural, moral, and social values. This paper argues for an adaptable framework to accommodate diverse cultural and religious perspectives. By using an adaptive ethics model, research protections can reflect various populations and foster growth in stem cell research possibilities.

INTRODUCTION

Stem cell research combines biology, medicine, and technology, promising to alter health care and the understanding of human development. Yet, ethical contention exists because of individuals’ perceptions of using human embryos based on their various cultural, moral, and social values. While these disagreements concerning policy, use, and general acceptance have prompted the development of an international ethics policy, such a uniform approach can overlook the nuanced ethical landscapes between cultures. With diverse viewpoints in public health, a single global policy, especially one reflecting Western ethics or the ethics prevalent in high-income countries, is impractical. This paper argues for a culturally sensitive, adaptable framework for the use of embryonic stem cells. Stem cell policy should accommodate varying ethical viewpoints and promote an effective global dialogue. With an extension of an ethics model that can adapt to various cultures, we recommend localized guidelines that reflect the moral views of the people those guidelines serve.

Stem cells, characterized by their unique ability to differentiate into various cell types, enable the repair or replacement of damaged tissues. Two primary types of stem cells are somatic stem cells (adult stem cells) and embryonic stem cells. Adult stem cells exist in developed tissues and maintain the body’s repair processes. [1] Embryonic stem cells (ESC) are remarkably pluripotent or versatile, making them valuable in research. [2] However, the use of ESCs has sparked ethics debates. Considering the potential of embryonic stem cells, research guidelines are essential. The International Society for Stem Cell Research (ISSCR) provides international stem cell research guidelines. They call for “public conversations touching on the scientific significance as well as the societal and ethical issues raised by ESC research.” [3] The ISSCR also publishes updates about culturing human embryos 14 days post fertilization, suggesting local policies and regulations should continue to evolve as ESC research develops. [4]  Like the ISSCR, which calls for local law and policy to adapt to developing stem cell research given cultural acceptance, this paper highlights the importance of local social factors such as religion and culture.

I.     Global Cultural Perspective of Embryonic Stem Cells

Views on ESCs vary throughout the world. Some countries readily embrace stem cell research and therapies, while others have stricter regulations due to ethical concerns surrounding embryonic stem cells and when an embryo becomes entitled to moral consideration. The philosophical issue of when the “someone” begins to be a human after fertilization, in the morally relevant sense, [5] impacts when an embryo becomes not just worthy of protection but morally entitled to it. The process of creating embryonic stem cell lines involves the destruction of the embryos for research. [6] Consequently, global engagement in ESC research depends on social-cultural acceptability.

a.     US and Rights-Based Cultures

In the United States, attitudes toward stem cell therapies are diverse. The ethics and social approaches, which value individualism, [7] trigger debates regarding the destruction of human embryos, creating a complex regulatory environment. For example, the 1996 Dickey-Wicker Amendment prohibited federal funding for the creation of embryos for research and the destruction of embryos for “more than allowed for research on fetuses in utero.” [8] Following suit, in 2001, the Bush Administration heavily restricted stem cell lines for research. However, the Stem Cell Research Enhancement Act of 2005 was proposed to help develop ESC research but was ultimately vetoed. [9] Under the Obama administration, in 2009, an executive order lifted restrictions allowing for more development in this field. [10] The flux of research capacity and funding parallels the different cultural perceptions of human dignity of the embryo and how it is socially presented within the country’s research culture. [11]

b.     Ubuntu and Collective Cultures

African bioethics differs from Western individualism because of the different traditions and values. African traditions, as described by individuals from South Africa and supported by some studies in other African countries, including Ghana and Kenya, follow the African moral philosophies of Ubuntu or Botho and Ukama , which “advocates for a form of wholeness that comes through one’s relationship and connectedness with other people in the society,” [12] making autonomy a socially collective concept. In this context, for the community to act autonomously, individuals would come together to decide what is best for the collective. Thus, stem cell research would require examining the value of the research to society as a whole and the use of the embryos as a collective societal resource. If society views the source as part of the collective whole, and opposes using stem cells, compromising the cultural values to pursue research may cause social detachment and stunt research growth. [13] Based on local culture and moral philosophy, the permissibility of stem cell research depends on how embryo, stem cell, and cell line therapies relate to the community as a whole . Ubuntu is the expression of humanness, with the person’s identity drawn from the “’I am because we are’” value. [14] The decision in a collectivistic culture becomes one born of cultural context, and individual decisions give deference to others in the society.

Consent differs in cultures where thought and moral philosophy are based on a collective paradigm. So, applying Western bioethical concepts is unrealistic. For one, Africa is a diverse continent with many countries with different belief systems, access to health care, and reliance on traditional or Western medicines. Where traditional medicine is the primary treatment, the “’restrictive focus on biomedically-related bioethics’” [is] problematic in African contexts because it neglects bioethical issues raised by traditional systems.” [15] No single approach applies in all areas or contexts. Rather than evaluating the permissibility of ESC research according to Western concepts such as the four principles approach, different ethics approaches should prevail.

Another consideration is the socio-economic standing of countries. In parts of South Africa, researchers have not focused heavily on contributing to the stem cell discourse, either because it is not considered health care or a health science priority or because resources are unavailable. [16] Each country’s priorities differ given different social, political, and economic factors. In South Africa, for instance, areas such as maternal mortality, non-communicable diseases, telemedicine, and the strength of health systems need improvement and require more focus. [17] Stem cell research could benefit the population, but it also could divert resources from basic medical care. Researchers in South Africa adhere to the National Health Act and Medicines Control Act in South Africa and international guidelines; however, the Act is not strictly enforced, and there is no clear legislation for research conduct or ethical guidelines. [18]

Some parts of Africa condemn stem cell research. For example, 98.2 percent of the Tunisian population is Muslim. [19] Tunisia does not permit stem cell research because of moral conflict with a Fatwa. Religion heavily saturates the regulation and direction of research. [20] Stem cell use became permissible for reproductive purposes only recently, with tight restrictions preventing cells from being used in any research other than procedures concerning ART/IVF.  Their use is conditioned on consent, and available only to married couples. [21] The community's receptiveness to stem cell research depends on including communitarian African ethics.

c.     Asia

Some Asian countries also have a collective model of ethics and decision making. [22] In China, the ethics model promotes a sincere respect for life or human dignity, [23] based on protective medicine. This model, influenced by Traditional Chinese Medicine (TCM), [24] recognizes Qi as the vital energy delivered via the meridians of the body; it connects illness to body systems, the body’s entire constitution, and the universe for a holistic bond of nature, health, and quality of life. [25] Following a protective ethics model, and traditional customs of wholeness, investment in stem cell research is heavily desired for its applications in regenerative therapies, disease modeling, and protective medicines. In a survey of medical students and healthcare practitioners, 30.8 percent considered stem cell research morally unacceptable while 63.5 percent accepted medical research using human embryonic stem cells. Of these individuals, 89.9 percent supported increased funding for stem cell research. [26] The scientific community might not reflect the overall population. From 1997 to 2019, China spent a total of $576 million (USD) on stem cell research at 8,050 stem cell programs, increased published presence from 0.6 percent to 14.01 percent of total global stem cell publications as of 2014, and made significant strides in cell-based therapies for various medical conditions. [27] However, while China has made substantial investments in stem cell research and achieved notable progress in clinical applications, concerns linger regarding ethical oversight and transparency. [28] For example, the China Biosecurity Law, promoted by the National Health Commission and China Hospital Association, attempted to mitigate risks by introducing an institutional review board (IRB) in the regulatory bodies. 5800 IRBs registered with the Chinese Clinical Trial Registry since 2021. [29] However, issues still need to be addressed in implementing effective IRB review and approval procedures.

The substantial government funding and focus on scientific advancement have sometimes overshadowed considerations of regional cultures, ethnic minorities, and individual perspectives, particularly evident during the one-child policy era. As government policy adapts to promote public stability, such as the change from the one-child to the two-child policy, [30] research ethics should also adapt to ensure respect for the values of its represented peoples.

Japan is also relatively supportive of stem cell research and therapies. Japan has a more transparent regulatory framework, allowing for faster approval of regenerative medicine products, which has led to several advanced clinical trials and therapies. [31] South Korea is also actively engaged in stem cell research and has a history of breakthroughs in cloning and embryonic stem cells. [32] However, the field is controversial, and there are issues of scientific integrity. For example, the Korean FDA fast-tracked products for approval, [33] and in another instance, the oocyte source was unclear and possibly violated ethical standards. [34] Trust is important in research, as it builds collaborative foundations between colleagues, trial participant comfort, open-mindedness for complicated and sensitive discussions, and supports regulatory procedures for stakeholders. There is a need to respect the culture’s interest, engagement, and for research and clinical trials to be transparent and have ethical oversight to promote global research discourse and trust.

d.     Middle East

Countries in the Middle East have varying degrees of acceptance of or restrictions to policies related to using embryonic stem cells due to cultural and religious influences. Saudi Arabia has made significant contributions to stem cell research, and conducts research based on international guidelines for ethical conduct and under strict adherence to guidelines in accordance with Islamic principles. Specifically, the Saudi government and people require ESC research to adhere to Sharia law. In addition to umbilical and placental stem cells, [35] Saudi Arabia permits the use of embryonic stem cells as long as they come from miscarriages, therapeutic abortions permissible by Sharia law, or are left over from in vitro fertilization and donated to research. [36] Laws and ethical guidelines for stem cell research allow the development of research institutions such as the King Abdullah International Medical Research Center, which has a cord blood bank and a stem cell registry with nearly 10,000 donors. [37] Such volume and acceptance are due to the ethical ‘permissibility’ of the donor sources, which do not conflict with religious pillars. However, some researchers err on the side of caution, choosing not to use embryos or fetal tissue as they feel it is unethical to do so. [38]

Jordan has a positive research ethics culture. [39] However, there is a significant issue of lack of trust in researchers, with 45.23 percent (38.66 percent agreeing and 6.57 percent strongly agreeing) of Jordanians holding a low level of trust in researchers, compared to 81.34 percent of Jordanians agreeing that they feel safe to participate in a research trial. [40] Safety testifies to the feeling of confidence that adequate measures are in place to protect participants from harm, whereas trust in researchers could represent the confidence in researchers to act in the participants’ best interests, adhere to ethical guidelines, provide accurate information, and respect participants’ rights and dignity. One method to improve trust would be to address communication issues relevant to ESC. Legislation surrounding stem cell research has adopted specific language, especially concerning clarification “between ‘stem cells’ and ‘embryonic stem cells’” in translation. [41] Furthermore, legislation “mandates the creation of a national committee… laying out specific regulations for stem-cell banking in accordance with international standards.” [42] This broad regulation opens the door for future global engagement and maintains transparency. However, these regulations may also constrain the influence of research direction, pace, and accessibility of research outcomes.

e.     Europe

In the European Union (EU), ethics is also principle-based, but the principles of autonomy, dignity, integrity, and vulnerability are interconnected. [43] As such, the opportunity for cohesion and concessions between individuals’ thoughts and ideals allows for a more adaptable ethics model due to the flexible principles that relate to the human experience The EU has put forth a framework in its Convention for the Protection of Human Rights and Dignity of the Human Being allowing member states to take different approaches. Each European state applies these principles to its specific conventions, leading to or reflecting different acceptance levels of stem cell research. [44]

For example, in Germany, Lebenzusammenhang , or the coherence of life, references integrity in the unity of human culture. Namely, the personal sphere “should not be subject to external intervention.” [45]  Stem cell interventions could affect this concept of bodily completeness, leading to heavy restrictions. Under the Grundgesetz, human dignity and the right to life with physical integrity are paramount. [46] The Embryo Protection Act of 1991 made producing cell lines illegal. Cell lines can be imported if approved by the Central Ethics Commission for Stem Cell Research only if they were derived before May 2007. [47] Stem cell research respects the integrity of life for the embryo with heavy specifications and intense oversight. This is vastly different in Finland, where the regulatory bodies find research more permissible in IVF excess, but only up to 14 days after fertilization. [48] Spain’s approach differs still, with a comprehensive regulatory framework. [49] Thus, research regulation can be culture-specific due to variations in applied principles. Diverse cultures call for various approaches to ethical permissibility. [50] Only an adaptive-deliberative model can address the cultural constructions of self and achieve positive, culturally sensitive stem cell research practices. [51]

II.     Religious Perspectives on ESC

Embryonic stem cell sources are the main consideration within religious contexts. While individuals may not regard their own religious texts as authoritative or factual, religion can shape their foundations or perspectives.

The Qur'an states:

“And indeed We created man from a quintessence of clay. Then We placed within him a small quantity of nutfa (sperm to fertilize) in a safe place. Then We have fashioned the nutfa into an ‘alaqa (clinging clot or cell cluster), then We developed the ‘alaqa into mudgha (a lump of flesh), and We made mudgha into bones, and clothed the bones with flesh, then We brought it into being as a new creation. So Blessed is Allah, the Best of Creators.” [52]

Many scholars of Islam estimate the time of soul installment, marked by the angel breathing in the soul to bring the individual into creation, as 120 days from conception. [53] Personhood begins at this point, and the value of life would prohibit research or experimentation that could harm the individual. If the fetus is more than 120 days old, the time ensoulment is interpreted to occur according to Islamic law, abortion is no longer permissible. [54] There are a few opposing opinions about early embryos in Islamic traditions. According to some Islamic theologians, there is no ensoulment of the early embryo, which is the source of stem cells for ESC research. [55]

In Buddhism, the stance on stem cell research is not settled. The main tenets, the prohibition against harming or destroying others (ahimsa) and the pursuit of knowledge (prajña) and compassion (karuna), leave Buddhist scholars and communities divided. [56] Some scholars argue stem cell research is in accordance with the Buddhist tenet of seeking knowledge and ending human suffering. Others feel it violates the principle of not harming others. Finding the balance between these two points relies on the karmic burden of Buddhist morality. In trying to prevent ahimsa towards the embryo, Buddhist scholars suggest that to comply with Buddhist tenets, research cannot be done as the embryo has personhood at the moment of conception and would reincarnate immediately, harming the individual's ability to build their karmic burden. [57] On the other hand, the Bodhisattvas, those considered to be on the path to enlightenment or Nirvana, have given organs and flesh to others to help alleviate grieving and to benefit all. [58] Acceptance varies on applied beliefs and interpretations.

Catholicism does not support embryonic stem cell research, as it entails creation or destruction of human embryos. This destruction conflicts with the belief in the sanctity of life. For example, in the Old Testament, Genesis describes humanity as being created in God’s image and multiplying on the Earth, referencing the sacred rights to human conception and the purpose of development and life. In the Ten Commandments, the tenet that one should not kill has numerous interpretations where killing could mean murder or shedding of the sanctity of life, demonstrating the high value of human personhood. In other books, the theological conception of when life begins is interpreted as in utero, [59] highlighting the inviolability of life and its formation in vivo to make a religious point for accepting such research as relatively limited, if at all. [60] The Vatican has released ethical directives to help apply a theological basis to modern-day conflicts. The Magisterium of the Church states that “unless there is a moral certainty of not causing harm,” experimentation on fetuses, fertilized cells, stem cells, or embryos constitutes a crime. [61] Such procedures would not respect the human person who exists at these stages, according to Catholicism. Damages to the embryo are considered gravely immoral and illicit. [62] Although the Catholic Church officially opposes abortion, surveys demonstrate that many Catholic people hold pro-choice views, whether due to the context of conception, stage of pregnancy, threat to the mother’s life, or for other reasons, demonstrating that practicing members can also accept some but not all tenets. [63]

Some major Jewish denominations, such as the Reform, Conservative, and Reconstructionist movements, are open to supporting ESC use or research as long as it is for saving a life. [64] Within Judaism, the Talmud, or study, gives personhood to the child at birth and emphasizes that life does not begin at conception: [65]

“If she is found pregnant, until the fortieth day it is mere fluid,” [66]

Whereas most religions prioritize the status of human embryos, the Halakah (Jewish religious law) states that to save one life, most other religious laws can be ignored because it is in pursuit of preservation. [67] Stem cell research is accepted due to application of these religious laws.

We recognize that all religions contain subsets and sects. The variety of environmental and cultural differences within religious groups requires further analysis to respect the flexibility of religious thoughts and practices. We make no presumptions that all cultures require notions of autonomy or morality as under the common morality theory , which asserts a set of universal moral norms that all individuals share provides moral reasoning and guides ethical decisions. [68] We only wish to show that the interaction with morality varies between cultures and countries.

III.     A Flexible Ethical Approach

The plurality of different moral approaches described above demonstrates that there can be no universally acceptable uniform law for ESC on a global scale. Instead of developing one standard, flexible ethical applications must be continued. We recommend local guidelines that incorporate important cultural and ethical priorities.

While the Declaration of Helsinki is more relevant to people in clinical trials receiving ESC products, in keeping with the tradition of protections for research subjects, consent of the donor is an ethical requirement for ESC donation in many jurisdictions including the US, Canada, and Europe. [69] The Declaration of Helsinki provides a reference point for regulatory standards and could potentially be used as a universal baseline for obtaining consent prior to gamete or embryo donation.

For instance, in Columbia University’s egg donor program for stem cell research, donors followed standard screening protocols and “underwent counseling sessions that included information as to the purpose of oocyte donation for research, what the oocytes would be used for, the risks and benefits of donation, and process of oocyte stimulation” to ensure transparency for consent. [70] The program helped advance stem cell research and provided clear and safe research methods with paid participants. Though paid participation or covering costs of incidental expenses may not be socially acceptable in every culture or context, [71] and creating embryos for ESC research is illegal in many jurisdictions, Columbia’s program was effective because of the clear and honest communications with donors, IRBs, and related stakeholders.  This example demonstrates that cultural acceptance of scientific research and of the idea that an egg or embryo does not have personhood is likely behind societal acceptance of donating eggs for ESC research. As noted, many countries do not permit the creation of embryos for research.

Proper communication and education regarding the process and purpose of stem cell research may bolster comprehension and garner more acceptance. “Given the sensitive subject material, a complete consent process can support voluntary participation through trust, understanding, and ethical norms from the cultures and morals participants value. This can be hard for researchers entering countries of different socioeconomic stability, with different languages and different societal values. [72]

An adequate moral foundation in medical ethics is derived from the cultural and religious basis that informs knowledge and actions. [73] Understanding local cultural and religious values and their impact on research could help researchers develop humility and promote inclusion.

IV.     Concerns

Some may argue that if researchers all adhere to one ethics standard, protection will be satisfied across all borders, and the global public will trust researchers. However, defining what needs to be protected and how to define such research standards is very specific to the people to which standards are applied. We suggest that applying one uniform guide cannot accurately protect each individual because we all possess our own perceptions and interpretations of social values. [74] Therefore, the issue of not adjusting to the moral pluralism between peoples in applying one standard of ethics can be resolved by building out ethics models that can be adapted to different cultures and religions.

Other concerns include medical tourism, which may promote health inequities. [75] Some countries may develop and approve products derived from ESC research before others, compromising research ethics or drug approval processes. There are also concerns about the sale of unauthorized stem cell treatments, for example, those without FDA approval in the United States. Countries with robust research infrastructures may be tempted to attract medical tourists, and some customers will have false hopes based on aggressive publicity of unproven treatments. [76]

For example, in China, stem cell clinics can market to foreign clients who are not protected under the regulatory regimes. Companies employ a marketing strategy of “ethically friendly” therapies. Specifically, in the case of Beike, China’s leading stem cell tourism company and sprouting network, ethical oversight of administrators or health bureaus at one site has “the unintended consequence of shifting questionable activities to another node in Beike's diffuse network.” [77] In contrast, Jordan is aware of stem cell research’s potential abuse and its own status as a “health-care hub.” Jordan’s expanded regulations include preserving the interests of individuals in clinical trials and banning private companies from ESC research to preserve transparency and the integrity of research practices. [78]

The social priorities of the community are also a concern. The ISSCR explicitly states that guidelines “should be periodically revised to accommodate scientific advances, new challenges, and evolving social priorities.” [79] The adaptable ethics model extends this consideration further by addressing whether research is warranted given the varying degrees of socioeconomic conditions, political stability, and healthcare accessibilities and limitations. An ethical approach would require discussion about resource allocation and appropriate distribution of funds. [80]

While some religions emphasize the sanctity of life from conception, which may lead to public opposition to ESC research, others encourage ESC research due to its potential for healing and alleviating human pain. Many countries have special regulations that balance local views on embryonic personhood, the benefits of research as individual or societal goods, and the protection of human research subjects. To foster understanding and constructive dialogue, global policy frameworks should prioritize the protection of universal human rights, transparency, and informed consent. In addition to these foundational global policies, we recommend tailoring local guidelines to reflect the diverse cultural and religious perspectives of the populations they govern. Ethics models should be adapted to local populations to effectively establish research protections, growth, and possibilities of stem cell research.

For example, in countries with strong beliefs in the moral sanctity of embryos or heavy religious restrictions, an adaptive model can allow for discussion instead of immediate rejection. In countries with limited individual rights and voice in science policy, an adaptive model ensures cultural, moral, and religious views are taken into consideration, thereby building social inclusion. While this ethical consideration by the government may not give a complete voice to every individual, it will help balance policies and maintain the diverse perspectives of those it affects. Embracing an adaptive ethics model of ESC research promotes open-minded dialogue and respect for the importance of human belief and tradition. By actively engaging with cultural and religious values, researchers can better handle disagreements and promote ethical research practices that benefit each society.

This brief exploration of the religious and cultural differences that impact ESC research reveals the nuances of relative ethics and highlights a need for local policymakers to apply a more intense adaptive model.

Culturally, autonomy practices follow a relational autonomy approach based on a paternalistic deontological health care model. The adherence to strict international research policies and religious pillars within the regulatory environment is a great foundation for research ethics. However, there is a need to develop locally targeted ethics approaches for research (as called for in Alahmad, G., Aljohani, S., & Najjar, M. F. (2020). Ethical challenges regarding the use of stem cells: interviews with researchers from Saudi Arabia. BMC medical ethics, 21(1), 35. https://doi.org/10.1186/s12910-020-00482-6), this decision-making approach may help advise a research decision model.

[43] The EU’s definition of autonomy relates to the capacity for creating ideas, moral insight, decisions, and actions without constraint, personal responsibility, and informed consent. However, the EU views autonomy as not completely able to protect individuals and depends on other principles, such as dignity, which “expresses the intrinsic worth and fundamental equality of all human beings.” Rendtorff, J.D., Kemp, P.

[59] There is no explicit religious reference to when life begins or how to conduct research that interacts with the concept of life. However, these are relevant verses pertaining to how the fetus is viewed. (( King James Bible . (1999). Oxford University Press. (original work published 1769))

Jerimiah 1: 5 “Before I formed thee in the belly I knew thee; and before thou camest forth out of the womb I sanctified thee…”

In prophet Jerimiah’s insight, God set him apart as a person known before childbirth, a theme carried within the Psalm of David.

Psalm 139: 13-14 “…Thou hast covered me in my mother's womb. I will praise thee; for I am fearfully and wonderfully made…”

These verses demonstrate David’s respect for God as an entity that would know of all man’s thoughts and doings even before birth.
