| Summary: | Policies atoning for past wrongs against minority groups are often contested within the majority. During the year after the apology to the Indigenous Australian Stolen Generations, predictors of non-Indigenous (majority) collective action intentions focusing on support or opposition to reform reconciliation policies (Study 1, N = 206) and compensation to the Stolen Generations (Study 2, N = 215; Study 3, N = 298) were examined. Action was analyzed as a function of national identity, opinion-based group identity, group-based guilt, political orientation, and collective efficacy. Opinion-based group identification was an independent predictor of action for all groups except for anti-compensation, where efficacy strongly predicted action. Findings highlight opinion-based groups' role in capturing the fault lines of disagreement within majority groups.
