How prosocial actors use power hierarchies to build moral reputation

Power hierarchies are ubiquitous, emerging formally and informally, in both personal and professional contexts. When prosocial acts are offered within power hierarchies, there is a widespread belief that people who choose lower-power beneficiaries are altruistically motivated, and that those who choose higher-power beneficiaries hold a self-interested motive to ingratiate. In contrast, the current research empirically demonstrates that people can also choose lower-power beneficiaries for self-interested reasons - namely, to bolster their own moral reputation in the group. Across three pre-registered studies, involving different contexts and types of prosocial behavior, and including real financial incentives, we demonstrate that people are more likely to choose lower -power beneficiaries when reputation concerns are more salient. We also provide evidence of the mechanism underlying this pattern: people believe that choosing a lower-power beneficiary more effectively signals their own moral character.
