Disidentification, the psychological distancing from unpleasant group memberships, has mainly been studied in individualistic societies. We tested whether disidentification is a coping strategy to deal with conflicts in small and large groups, in Japan and Germany. Study 1 (N = 79) illustrates that Japanese recalled more unpleasant situations related to small than large groups. Study 2 (N = 198) confirms that Japanese, but not German students’ disidentification varied with group size and was stronger after small‐group conflict. Study 3 (N = 132) shows that anger was related to disidentification in Japan but to confrontation in Germany. Study 4 (N = 335) shows that, after group conflict, Japanese felt relieved when imagining to disidentify, whereas Germans felt relieved when imagining to confront the source of conflict. Combining correlational and experimental designs with culture‐sensitive situation sampling, we show that disidentification exists as a psychological construct across cultures, albeit serving different psychological functions.
