With or without you? Perceived indispensability and opposition to separatist movements.

Abstract

Positive intergroup relations are shown to be related to the perception that, despite mutual differences, all subgroups are indispensable for the identity or functioning of the overall society. Yet, so far, the research on identity and functional indispensability is concerned with minorities that strive for inclusion in the larger nation-state (e.g., immigrants). In contrast, we examined the roles of identity and functional indispensability in the context of separatist movements. In Study 1 (N=397), we found that Han Chinese' perceptions of identity and functional indispensability of Tibetans and Uyghurs were associated with higher willingness to engage in collective action against these groups' separatist movements. We replicated these findings in Study 2a and 2b among a diverse sample of the Dutch concerning the Brexit (N=378) and Frexit (N =279). In experimental Study 3, again among the Dutch (N=405), we found that indispensability increased anti-Frexit action intentions. We conclude that, in the context of separatist movements, perceived indispensability can make attitudes towards separatist movements more antagonistic. The findings contribute to a better understanding of intergroup relations when subgroups' interests clash.
