Crises are widely acknowledged as catalysts for policy change. Yet, our understanding of the policy effects of crises remains limited. Why do only some crises lead to major changes, while significant policy changes also occur during seemingly non‐crisis periods? This paper addresses this gap by distinguishing between two critical “components” of crises: objective problem pressures and public perceptions. We argue that these components often co‐occur but may not always align, leading to differing changes in policy outputs. Using migration policy in Switzerland as a crucial case study, we explore fluctuations in both objective metrics and public sentiment over a period of 25 years (1994 to 2019). Our analysis reveals that substantial policy changes typically occur when both components highlight crisis conditions. However, notable policy change can also be triggered by either high objective pressures or strong public perceptions of crisis. These findings highlight the significance of how scholars define and conceptualize crises, as well as the dimensions—whether objective or perceptual—that they use.
