Theories of rationalities such as logic, probability theory and decision theory are used to explain, guide and evaluate actions. They fulfill both descriptive and normative functions. This raises the question of how these aspects interact. On the one hand, it is discussed what the role of normative theories of rationalities is in empirical research on human reasoning. On the other hand, there are questions concerning the justification of normative theories of rationality and the relevance of empirical evidence for this process of justification. Related to these issues is the question of whether and to what extent actual human choices are irrational and what implications this irrationality has for normative economics as a discipline in which theories of rationality are classically applied. The international and interdisciplinary workshop “Theories of Rationality: Descriptive and Normative Aspects“ aims to investigate these issues.
