꩜ Well, what is a case study?

A case study is not “a story.” It’s not “an example.” It’s not “someone’s experience” on TikTok.

A case study is a structured, documented analysis of a single case (or small set of cases) used to understand a phenomenon in context.

What counts as a “case” depends on the field:

• one person (clinical psych, medicine)

• one company (business, management)

• one event (history, policy)

• one community (sociology)

• one system failure (engineering)

• one courtroom case (law)

• one implementation (education, tech)

The key feature is this: case studies preserve context. They don’t strip the world down to variables the way many experiments do. They show how things behave in messy reality.

꩜ Why they’re important

They reveal mechanisms in the wild. Quant studies can show “X correlates with Y.” Case studies can show the step-by-step pathway of how X becomes Y.

They capture complexity without pretending it’s simple. Real systems have feedback loops, confounds, constraints, personalities, environments. Case studies let you see those interacting.

They generate hypotheses. A lot of research begins with a weird case that doesn’t fit the model. Case studies help you notice what the model missed.

They teach application. If you’re learning to do something (therapy, teaching, strategy, product design), case studies show how decisions play out.

They’re often the strongest evidence available in rare or unethical-to-test situations. You can’t ethically run randomized experiments on everything (trauma, disasters, rare diseases). Case studies become crucial.

What case studies are NOT good for

This matters for honesty.

Case studies generally cannot prove:

• population-level causation

• broad generalizability

• “this will work for everyone” conclusions

A case study can show what happened, how, and why it might have happened — but it’s weak for universal claims unless repeated across many cases.

꩜ There are several types of case studies:

Exploratory: These are preliminary studies used to identify research questions and hypotheses. For instance, an exploratory case study might investigate a newly emerging social trend to identify the key factors driving it. By gathering preliminary data and insights, researchers can shape their future studies with more focused questions and objectives.

⸻⸻⊹ ࣪

Explanatory: They aim to explain how and why a particular phenomenon occurs. For example, a researcher might use an explanatory case study to understand why a particular public health intervention succeeded in one community but failed in another. These studies often involve detailed analysis of causal relationships and are particularly valuable in testing theories.

⸻⸻⊹ ࣪

Descriptive: These provide a detailed account of an event or situation. For instance, a descriptive case study might document the response of a community to a natural disaster, detailing the actions taken, the challenges faced, and the outcomes achieved. This type of case study helps to paint a vivid picture of the subject, offering insights that can inform future actions or policies.

⸻⸻⊹ ࣪

Intrinsic: Focused on a specific case for its own sake, often because it is unique or unusual. For example, a study of a rare medical condition in a single patient would be intrinsic, as the case itself is of primary interest. These studies are less about generalization and more about understanding the case in its entirety, providing valuable insights into something that is not commonly observed.

⸻⸻⊹ ࣪

Instrumental: Used to gain a deeper understanding of a particular issue or to refine theory. An instrumental case study might focus on a specific school to explore broader questions about educational inequality. The specific case is not just an end in itself but serves as a means to shed light on larger, more generalizable issues.

When working with case studies, it’s not enough to simply find one that looks interesting; you need to ensure that it truly fits your research or situation. This is where relevance and applicability come into play.

Relevance refers to how closely the case study aligns with the specific issues or questions you’re dealing with. For example, if you’re researching customer satisfaction in the tech industry, a case study focused on a similar industry and customer base would be more relevant than one from a completely different field.

Applicability, on the other hand, is about whether the findings or lessons from the case study can be directly applied to your own work. This involves looking at the specifics—are the challenges faced in the case study similar to yours? Can the strategies or solutions used be adapted to your context? By carefully considering both relevance and applicability, you ensure that the case studies you choose will provide meaningful insights and guidance for your research or practical problem-solving.

How to know you found a real case study (quick authenticity test)

A real case study usually includes:

• clear case definition (what is the “case”?)

• background/context

• timeline or setting

• methods of data collection (interviews, observation, records, measures)

• outcomes/results

• interpretation/lessons

• limitations (good ones admit constraints)

⸻⸻⊹ ࣪

Red flags:

• no methods

• no context

• vague claims with no metrics

• only success story, no tradeoffs

• “case study” used as a fancy word for a testimonial

⸻⸻⊹ ࣪

You want to extract:

Context: what conditions made this possible?

Mechanism: what steps caused what?

Constraints: what limited the outcome?

Transferability: what parts apply to your situation, what parts don’t?

Hypotheses: what should be tested next?
