Final answer:
A primary disadvantage of the case study method is its lack of generalizability, as conclusions drawn from a single case may not be applicable to the larger population due to the method's inherent focus on specific, detailed scenarios.
Step-by-step explanation:
One disadvantage of the case study method is that it does not provide findings that can be generalized. This is a significant limitation since case studies often focus on a single case or individual, which provides in-depth information but lacks broader applicability. Although rich in detail, the findings from a case study cannot be reliably applied to the larger population due to their specificity to the unique case or individual under scrutiny.
Case studies are frequently used to explore unique or complex instances, but the inability to generalize from these findings to a broader context is a major criticism of this method. Researchers often desire outcomes that can extend their implications across a more varied group or societal segment. Moreover, the qualitative nature of case study research involves subjective evidence that can be difficult to control and replicate, further impeding generalization.
