-
Subjectivity and Bias: Case studies are prone to subjectivity and researcher bias. The researcher’s interpretations, preconceived notions, and personal biases can influence the data collection, analysis, and conclusions, potentially leading to skewed results.
-
Time and Resource Intensive: Conducting a thorough case study can be time-consuming and resource-intensive. It involves extensive data collection, in-depth analysis, and careful validation of findings, which may require significant investments of time, effort, and resources.
-
Difficulty in Replication: Due to their unique and context-specific nature, case studies can be challenging to replicate. Replication is essential for validating research findings and establishing their reliability, but it may not always be feasible with case study designs.
-
Risk of Overlooking Alternative Explanations: Researchers using case study methodology must be vigilant about not overlooking alternative explanations or competing hypotheses. The complexity of real-world cases can make it challenging to identify all possible factors influencing the outcomes.
-
Potential for Misinterpretation: Complex cases may be susceptible to misinterpretation or misrepresentation of data. Researchers must exercise caution in interpreting findings and ensure that conclusions are grounded in rigorous analysis and evidence.
-
Limited Control Over Variables: Unlike experimental designs, case studies offer limited control over variables. This lack of control can make it difficult to establish causal relationships or determine the precise impact of specific factors on the outcomes observed.
Despite these limitations, case study methodology remains a valuable and widely used research approach, particularly in exploratory and descriptive studies. Researchers can mitigate some of the drawbacks by employing rigorous methods, triangulating data sources, engaging in reflexivity, and acknowledging the limitations of their findings. Overall, case studies contribute valuable insights to the body of knowledge in various fields and play a crucial role in advancing research and understanding complex phenomena.
