Academic Abstract Advantaged group allies have multiple motives for supporting equality, raising questions about their sincerity. We draw upon the covariation model of attributions to explain how disadvantaged group members make attributions about whether advantaged group “allies” are sincerely motivated to empower the disadvantaged group. We propose an Attribution-Identity Model of Sincerity (AIMS) which posits that disadvantaged group members view advantaged group members as sincere allies when they support equality in the presence of inhibitory causes and in the absence of facilitative causes, exceed expectations for the advantaged group, and provide support across time and contexts. Furthermore, those who identify strongly with their disadvantaged group and perceive intergroup inequality as illegitimate are most motivated to ascertain the sincerity of advantaged group members’ allyship. AIMS suggests how members of disadvantaged groups seek to maximize benefits and minimize risks of advantaged group members’ allyship. Public Abstract Advantaged group members (e.g., men, White Americans) can act as allies for disadvantaged groups (e.g., women, Americans belonging to minoritized racial groups), but members of disadvantaged groups sometimes have reason to question whether their motives are sincere. We argue that members of disadvantaged groups view advantaged group allies as more sincere when they support equality when they do not stand to benefit from it and even when they stand to lose. We also argue that members of disadvantaged groups view advantaged group allies as more sincere when their support for equality goes beyond expectations for their advantaged group, consistently over time, and is not limited to particular situations, forms, or contexts. Members of disadvantaged groups like sincere allies, want to work with them, and feel safe around them. Sincere allies also serve as moral exemplars to other members of advantaged groups.
