Case selection is a longstanding topic in the methodological literature. The workshop takes a comprehensive perspective on case selection by discussing it from a methodological and an applied perspective. On a methodological level, we deal with the rationale for random and intentional case selection and introduce different strategies of intentional case selection. We will see that the intelligible choice of cases hinges on the research goal and the type of case. We focus on different types of cases such as the typical case and the most-likely case and selection principles for each type. Moreover, we will link the choice of cases to different logics of comparisons and elaborate on the choice of cases for process tracing on the basis of large-n methods such as regression analysis and Qualitative Comparative Analysis (QCA).
