Social norms serve as efficient guidelines that specify which behavior is adequate in a given social context. Building on Conservation of Resources Theory, we argue that this is specifically the case under disruptive states and hypothesized that switching to daylight saving time result in harsher evaluations of norm violations. In a quasiexperimental study (N = 724), individuals rated norm violations on the Monday following the switch to daylight saving time more inappropriate than on a regular Monday. Because this finding was not robust, we conducted a direct replication with more rigorous exclusion criteria, a larger sample size (N = 986), and additional exploratory sleep-related indices. No effect of switching to daylight saving time on perceived inappropriateness was found. (PsycInfo Database Record (c) 2025 APA, all rights reserved)
