In this paper, we explore an under-investigated question concerning the class of formal models that aim at providing normative guidance. We call such models normative models. In particular, we examine the question of how normative models can successfully exert normative guidance. First, we highlight the absence of a discussion of this question—which is surprising given the extensive debate about the success conditions of descriptive models—and motivate its importance. Second, we introduce and discuss two potential accounts of the success conditions of normative models. Our tentative conclusion is that the second account is more promising.
