The effects of group memberships of victims and perpetrators in humanly caused disasters on charitable donations to victims

Abstract

AbstractThe effects of group memberships of disaster victims and perpetrators on charitable donations were measured. In Study 1 (N = 92), victim group membership was experimentally varied to demonstrate an ingroup bias. In Study 2 (N = 84), a similar bias was demonstrated by varying perpetrator group membership. In Study 3 (N = 182), both victim and perpetrator group memberships were assessed. Perpetrator group membership interacted with victim group membership. Moreover, donations were highest when both victims and perpetrators shared a group membership. These effects were mediated by empathy with the victims, and perceived responsibility of the donor to intervene and aid the victim. Findings show that a salient perpetrator group can be harnessed to encourage helping of disaster victims.
