The purpose of a paper in the social sciences designed around a case study is to thoroughly investigate a subject of analysis in order to reveal a new understanding about the research problem and, in so doing, contributing new knowledge to what is already known from previous studies. In general, the structure of a case study research paper is not all that different from a standard college-level research paper. However, there are subtle differences you should be aware of. Here are the key elements to organizing and writing a case study research paper.
As with any research paper, your introduction should serve as a roadmap for your readers to ascertain the scope and purpose of your study. The introduction to a case study research paper, however, should not only describe the research problem and its significance, but you should also succinctly describe why the case is being used and how it relates to addressing the problem. The two elements should be linked. With this in mind, a good introduction answers these four questions:
- What was I studying? Describe the research problem and describe the subject of analysis you have chosen to address the problem. Explain how they are linked and what elements of the case will help to expand knowledge and understanding about the problem.
- Why was this topic important to investigate? Describe the significance of the research problem and state why a case study design and the subject of analysis that the paper is designed around is appropriate in addressing the problem.
- What did we know about this topic before I did this study? Provide background that helps lead the reader into the more in-depth literature review to follow. If applicable, summarize prior case study research applied to the research problem and why it fails to adequately address the research problem. Describe why your case will be useful. If no prior case studies have been used to address the research problem, explain why you have selected this subject of analysis.
- How will this study advance new knowledge or new ways of understanding? Explain why your case study will be suitable in helping to expand knowledge and understanding about the research problem.
Each of these questions should be addressed in no more than a few paragraphs. Exceptions to this can be when you are addressing a complex research problem or subject of analysis that requires more in-depth background information.
II. Literature Review
The literature review for a case study research paper is generally structured the same as it is for any college-level research paper. The difference, however, is that the literature review is focused on providing background information and enabling historical interpretation of the subject of analysis in relation to the research problem the case is intended to address. This includes synthesizing studies that help to:
- Place relevant works in the context of their contribution to understanding the case study being investigated. This would include summarizing studies that have used a similar subject of analysis to investigate the research problem. If there is literature using the same or a very similar case to study, you need to explain why duplicating past research is important [e.g., conditions have changed; prior studies were conducted long ago, etc.].
- Describe the relationship each work has to the others under consideration that informs the reader why this case is applicable. Your literature review should include a description of any works that support using the case to study the research problem and the underlying research questions.
- Identify new ways to interpret prior research using the case study. If applicable, review any research that has examined the research problem using a different research design. Explain how your case study design may reveal new knowledge or a new perspective or that can redirect research in an important new direction.
- Resolve conflicts amongst seemingly contradictory previous studies. This refers to synthesizing any literature that points to unresolved issues of concern about the research problem and describing how the subject of analysis that forms the case study can help resolve these existing contradictions.
- Point the way in fulfilling a need for additional research. Your review should examine any literature that lays a foundation for understanding why your case study design and the subject of analysis around which you have designed your study may reveal a new way of approaching the research problem or offer a perspective that points to the need for additional research.
- Expose any gaps that exist in the literature that the case study could help to fill. Summarize any literature that not only shows how your subject of analysis contributes to understanding the research problem, but how your case contributes to a new way of understanding the problem that prior research has failed to do.
- Locate your own research within the context of existing literature [very important!]. Collectively, your literature review should always place your case study within the larger domain of prior research about the problem. The overarching purpose of reviewing pertinent literature in a case study paper is to demonstrate that you have thoroughly identified and synthesized prior studies in the context of explaining the relevance of the case in addressing the research problem.
In this section, you explain why you selected a particular subject of analysis to study and the strategy you used to identify and ultimately decide that your case was appropriate in addressing the research problem. The way you describe the methods used varies depending on the type of subject of analysis that frames your case study.
If your subject of analysis is an incident or event. In the social and behavioral sciences, the event or incident that represents the case to be studied is usually bounded by time and place, with a clear beginning and end and with an identifiable location or position relative to its surroundings. The subject of analysis can be of a rare or critical event or focus on a typical or regular event. The purpose of studying a rare event is to illuminate new ways of thinking about the broader research problem or to test a hypothesis. Critical incident case studies must describe the method by which you identified the event and explain the process by which you determined the validity of this case to inform broader perspectives about the research problem or to reveal new findings. However, the event does not have to be a rare or uniquely significant to support new thinking about the research problem or to challenge an existing hypothesis. For example, Walo, Bull, and Breen conducted a case study to identify and evaluate the direct and indirect economic benefits and costs of a local sports event in the City of Lismore, New South Wales, Australia. The purpose of their study was to provide new insights from measuring the impact of a typical local sports event that prior studies could not measure well because they focused on large "mega-events." Whether the event is rare or not, the methods section should include an explanation of the following characteristics of the event: when did it take place; what were the underlying circumstances leading to the event; what were the consequences of the event
If your subject of analysis is a person. Explain why you selected this particular individual to be studied and describe what experience he or she has had that provides an opportunity to advance new understandings about the research problem. Mention any background about this person which might help the reader understand the significance of his/her experiences that make them worthy of study. This includes describing the relationships this person has had with other people, institutions, and/or events that support using him or her as the subject for a case study research paper. It is particularly important to differentiate the person as the subject of analysis from others and to succinctly explain how the person relates to examining the research problem.
If your subject of analysis is a place. In general, a case study that investigates a place suggests a subject of analysis that is unique or special in some way and that this uniqueness can be used to build new understanding or knowledge about the research problem. A case study of a place must not only describe its various attributes relevant to the research problem [e.g., physical, social, cultural, economic, political, etc.], but you must state the method by which you determined that this place will illuminate new understandings about the research problem. It is also important to articulate why a particular place as the case for study is being used if similar places also exist [i.e., if you are studying patterns of homeless encampments of veterans in open spaces, why study Echo Park in Los Angeles rather than Griffith Park?] and, if applicable, what type of human activity involving this place makes it a good choice to study [prior research reveals Echo Park has more homeless veterans].
If your subject of analysis is a phenomenon. A phenomenon refers to a fact, occurrence, or circumstance that can be studied or observed but with the cause or explanation to be in question. In this sense, a phenomenon that forms your subject of analysis can encompass anything that can be observed or presumed to exist but is not fully understood. In the social and behavioral sciences, the case usually focuses on human interaction within a complex physical, social, economic, cultural, or political system. For example, the phenomenon could be the observation that many vehicles used by ISIS fighters are small trucks with English language advertisements on them. The research problem could be that ISIS fighters are difficult to combat because they are highly mobile. The research questions could be how and by what means are these vehicles used by ISIS being supplied to the militants and how might supply lines to these vehicles be cut? How might knowing the suppliers of these trucks from overseas reveal larger networks of collaborators and financial support? A case study of a phenomenon most often encompasses an in-depth analysis of a cause and effect that is grounded in an interactive relationship between people and their environment in some way.
NOTE: Evidence that supports the method by which you identified and chose your subject of analysis should be linked to the findings from the literature review. Be sure to cite any prior studies that helped you determine that the case you chose was appropriate for investigating the research problem.
The main elements of your discussion section are generally the same as any research paper, but centered around interpreting and drawing conclusions about the key findings from your case study. Note that a general social sciences research paper may contain a separate section to report findings. However, in a paper designed around a case study, it is more common to combine a description of the findings with the discussion about their implications. The objectives of your discussion section should include the following:
Reiterate the Research Problem/State the Major Findings
Briefly reiterate the research problem you are investigating and explain why the subject of analysis around which you designed the case study were used. You should then describe the findings revealed from your study of the case using direct, declarative, and succinct proclamation of the study results. Highlight any findings that were unexpected or especially profound.
Explain the Meaning of the Findings and Why They are Important
Systematically explain the meaning of your case study findings and why you believe they are important. Begin this part of the section by repeating what you consider to be your most important or surprising finding first, then systematically review each finding. Be sure to thoroughly extrapolate what your analysis of the case can tell the reader about situations or conditions beyond the actual case that was studied while, at the same time, being careful not to misconstrue or conflate a finding that undermines the external validity of your conclusions.
Relate the Findings to Similar Studies
No study in the social sciences is so novel or possesses such a restricted focus that it has absolutely no relation to previously published research. The discussion section should relate your case study results to those found in other studies, particularly if questions raised from prior studies served as the motivation for choosing your subject of analysis. This is important because comparing and contrasting the findings of other studies helps to support the overall importance of your results and it highlights how and in what ways your case study design and the subject of analysis differs from prior research about the topic.
Consider Alternative Explanations of the Findings
It is important to remember that the purpose of social science research is to discover and not to prove. When writing the discussion section, you should carefully consider all possible explanations for the case study results, rather than just those that fit your hypothesis or prior assumptions and biases. Be alert to what the in-depth analysis of the case may reveal about the research problem, including offering a contrarian perspective to what scholars have stated in prior research.
Acknowledge the Study's Limitations
You can state the study's limitations in the conclusion section of your paper but describing the limitations of your subject of analysis in the discussion section provides an opportunity to identify the limitations and explain why they are not significant. This part of the discussion section should also note any unanswered questions or issues your case study could not address. More detailed information about how to document any limitations to your research can be found here.
Suggest Areas for Further Research
Although your case study may offer important insights about the research problem, there are likely additional questions related to the problem that remain unanswered or findings that unexpectedly revealed themselves as a result of your in-depth analysis of the case. Be sure that the recommendations for further research are linked to the research problem and that you explain why your recommendations are valid in other contexts and based on the original assumptions of your study.
As with any research paper, you should summarize your conclusion in clear, simple language; emphasize how the findings from your case study differs from or supports prior research and why. Do not simply reiterate the discussion section. Provide a synthesis of key findings presented in the paper to show how these converge to address the research problem. If you haven't already done so in the discussion section, be sure to document the limitations of your case study and needs for further research.
The function of your paper's conclusion is to: 1) restate the main argument supported by the findings from the analysis of your case; 2) clearly state the context, background, and necessity of pursuing the research problem using a case study design in relation to an issue, controversy, or a gap found from reviewing the literature; and, 3) provide a place for you to persuasively and succinctly restate the significance of your research problem, given that the reader has now been presented with in-depth information about the topic.
Consider the following points to help ensure your conclusion is appropriate:
- If the argument or purpose of your paper is complex, you may need to summarize these points for your reader.
- If prior to your conclusion, you have not yet explained the significance of your findings or if you are proceeding inductively, use the conclusion of your paper to describe your main points and explain their significance.
- Move from a detailed to a general level of consideration of the case study's findings that returns the topic to the context provided by the introduction or within a new context that emerges from your case study findings.
Note that, depending on the discipline you are writing in and your professor's preferences, the concluding paragraph may contain your final reflections on the evidence presented applied to practice or on the essay's central research problem. However, the nature of being introspective about the subject of analysis you have investigated will depend on whether you are explicitly asked to express your observations in this way.
Problems to Avoid
One of the goals of a case study is to lay a foundation for understanding broader trends and issues applied to similar circumstances. However, be careful when drawing conclusions from your case study. They must be evidence-based and grounded in the results of the study; otherwise, it is merely speculation. Looking at a prior example, it would be incorrect to state that a factor in improving girls access to education in Azerbaijan and the policy implications this may have for improving access in other Muslim nations is due to girls access to social media if there is no documentary evidence from your case study to indicate this. There may be anecdotal evidence that retention rates were better for girls who were on social media, but this observation would only point to the need for further research and would not be a definitive finding if this was not a part of your original research agenda.
Failure to Document Limitations
No case is going to reveal all that needs to be understood about a research problem. Therefore, just as you have to clearly state the limitations of a general research study, you must describe the specific limitations inherent in the subject of analysis. For example, the case of studying how women conceptualize the need for water conservation in a village in Uganda could have limited application in other cultural contexts or in areas where fresh water from rivers or lakes is plentiful and, therefore, conservation is understood differently than preserving access to a scarce resource.
Failure to Extrapolate All Possible Implications
Just as you don't want to over-generalize from your case study findings, you also have to be thorough in the consideration of all possible outcomes or recommendations derived from your findings. If you do not, your reader may question the validity of your entire analysis, particularly if you failed to document an obvious outcome from your case study research. For example, in the case of studying the accident at the railroad crossing to evaluate where and what types of warning signals should be located, you failed to take into consideration speed limit signage as well as warning signals. When designing your case study, be sure you have thoroughly addressed all aspects of the problem and do not leave gaps in your analysis.

Political Science Department
Writing a Political Science Research Paper
Political Science students are asked to write a number of different kinds of papers, including reaction papers, compare and contrast essays, close reading/textual analysis papers, and synoptic papers. The research paper is thus only one type of political science paper. It is, however, a type that has quite specific components and requirements.
The Thesis Statement
The most important and most challenging task for students writing a research paper is developing a thesis. A thesis is a non-trivial, contestable, specific claim about political phenomena that can be proven or defended through the analysis of primary source material.
(1) Your thesis must be non-trivial
A reader will want evidence that you are exploring an important question or topic. Explorations of the unimportant (e.g., "Canada's orange industry has been underappreciated") will not entice any but the most insensate readers. Readers will recoil, in particular, from faux theses that merely state what the author has done (e.g., "I have researched the European Union's trade policy").
(2) Your thesis must be contestable
Do not seek to prove the obvious (e.g., African American voters disproportionately support Democratic candidates for the presidency). The best theses make counterintuitive claims (e.g., revolutions often occur when conditions improve in a country after a long period of deprivation). There must be, at a minimum, alternative explanations for the phenomena you are exploring or different possible answers to the question you are posing. A good research paper directly engages these competing arguments by demonstrating that its explanation or answer is the most plausible.
(3) Your thesis must make a specific claim
A thesis should reference specific concepts and focus on a delimited field of inquiry. Statements such as "religion is the chief cause of conflict in the world," "the International Criminal Court violates political sovereignty," and "the Russian people always want a czar to lead them" are neither specific nor delimited. An example of a specific, focused thesis would be "Religious divisions cause social conflict to increase in Northern Ireland when they are reinforced by other cleavages or divisions." This statement sports two concepts—social conflict and cross-cutting vs. reinforcing cleavages—that the author must develop or support in order to address the influence of religion on conflict in a specific context.
(4) You must employ primary sources to demonstrate or defend your thesis
A literature review or a review of pertinent secondary sources (i.e., published books or articles that interpret or analyze primary sources) is not sufficient to demonstrate a thesis. A literature review is, as noted below, a significant component of your research paper, but your objective is not merely to review what other scholars have said about your topic. Your objective is to say something novel about your topic. This will require you to step outside of the published literature to mine information that you acquire firsthand. Primary sources include (but are not limited to) public opinion surveys, demographic data (e.g., U.S. Census data), government documents, open-ended interviews conducted by the author, oral histories, archival materials (e.g., letters, policy memos, diary entries, interoffice communications, transcripts of conversations, etc.), and speeches.
The Literature Review
A literature review should accomplish two goals:
- Introduce your reader to the range of scholarship on your topic. This exercise can help you to provide your reader with some purchase on the complexity of your subject.
- Identify the most important competing arguments or claims about your topic.
As mentioned above, accomplishing #2 is integral to your effort to demonstrate or defend your thesis. You must first acquaint your reader with both the strengths and the weakness of competing arguments before you can demonstrate that your argument is superior.
Your literature review should address the most important or influential works on your topic. You will need to review books, monographs, and journal articles. Doing the last will require you to employ such research databases as JSTOR, ProQuest, and PAIS.
The Data Analysis
The form that your data analysis takes will be determined to a large degree by your choice of method or approach. If you are using statistical methods (e.g., regression analysis) or formal modeling (e.g., game theory) to analyze your data, then your paper will consist principally of justifying your choice of method, specifying your variables, and presenting and interpreting your results. Students performing quantitative analysis will need to think carefully about how best to present their findings (e.g., graphs, tables, charts, etc.). Such students could profit from reviewing Edward Tufte's classic book The Visual Display of Quantitative Information, particularly Tufte's discussions of "chartjunk."
If you are using qualitative data and methods, your paper will need to weave your findings into a narrative that is coherent, compelling, and probative. Students, for example, who decide to use the "case study approach" must devote some time to addressing the "small n problem." This, in short, is the challenge of explaining to the reader why one can generalize from a single or a small number of cases to a larger universe of cases. What makes your particular case or cases "crucial" or explanatory? It is not sufficient merely to claim that, for example, "there is a lot of information available on my case." You must choose your case or cases for sound theoretical reasons. Robert Michels, for example, decided to study the German Social Democratic Party to test his theory that all organizations are subject to "the iron law of oligarchy" because he posited that if power was concentrated in a small number of hands in a political party that sported a democratic ethos, then such oligarchic rule would surely occur in less ostentatiously democratic organizations.
A good conclusion should explain to the reader how your analysis has demonstrated that your argument is more persuasive than competing arguments. It should, in short, explain your contribution to the extant literature. Some pitfalls to sidestep when composing your conclusion are the following:
Do not go beyond your data
Even seasoned scholars can be guilty of concluding their pieces with grand statements that are not supported by their data. You can underscore your contribution to the literature without claiming that you have, for example, refuted all that has been written on your topic hitherto or created a "new paradigm." Showing respect for the work of other scholars, even that with which you disagree, is both courteous and sensible. Take care to identify the limitations of your findings or even some of the questionable parts of your analysis. Doing this will, if not immunize your work against criticism, at least allow you to get a jump on addressing some of the critiques that will be leveled at your work.
Do not sprinkle your conclusion with "questions for future research"
This is a complement of the above. Bear in mind that you are a novice researcher. It is more than a bit presumptuous to claim that your piece can be the foundation upon which other scholars will build.
Avoid boilerplate phrases such as "time will tell" or "no one can know for sure"
Conclusions are notorious for vaporous phrases that leave readers wondering, "What does that mean?" Take care that every sentence in your conclusion is meaningful (i.e., that it pertains to your argument). Short, tightly constructed and -argued conclusions are preferable to voluble, flabby conclusions that do not advance your case.
