What is a notable disadvantage of case studies?

A notable disadvantage of case studies lies in their potential for limited generalizability due to their narrow focus. Case studies typically examine a specific instance or a small number of instances in detail, which means that the findings derived from these studies may not be applicable to a larger population or different contexts. While they can provide deep insights into particular cases, the uniqueness of the cases studied often means that the results cannot be confidently extrapolated to broader groups. This narrow focus can limit the usefulness of case studies when trying to draw conclusions about wider trends or phenomena. Therefore, understanding this limitation is crucial when interpreting the findings from case studies and considering their applicability in various fields such as psychology, sociology, or health sciences.
