Fem missförstånd om fallstudieforskning

Abstract

Five misunderstandings about case-study research. This article examines five common  misunderstandings about case-study research: (1) Theoretical knowledge is more valuable than practical knowledge; (2) One cannot generalize from a single case, therefore the single case study cannot contribute to scientific development; (3) The case study is most useful for generating hypothesis, while other methods are more suitable for hypothesis testing and theory building; (4) the case study contains a bias towards verification; and (5) It is often difficult to summarize specific case studies. The article explains and correct these misunderstandings one by one and concludes with the Kuhnian insight that a scientific discipline without a large number of thoroughly executed case studies is a discipline without systematic production of exemplars, and that a discipline without exemplars is an ineffective one. Social science may be strengthened by the execution of more good case studies.
