The conflict of harmony: Intergroup contact, commonality and political solidarity between minority groups

Recent work on social change has complicated the picture regarding the influence of intergroup contact with majority groups on minority group membersʹ perceptions of inequality and willingness to engage in social action. The present research investigated the ability of a commonality-focused message to inspire political solidarity between minority groups, as well as the potential moderating role of intergroup contact with a majority group on the efficacy of this message for political solidarity. Across two experiments, as hypothesized, political solidarity from one minority group to another was highest within a commonality condition, relative to group-boundaries salient and control conditions, which was explained by increases in commonality perceptions. As expected, however, these effects were moderated by majority group contact, such that those with high levels of contact with majority group were less likely to show the commonality-to-political solidarity relation. Implications for intergroup contact and more broadly social change are discussed.
