This dissertation examines the potential dark side of organizational identification, by showing how identification by organizational members can interact with members' social dominance orientation (SDO) to predict mistreatment of constituents outside of an organization. I present a theoretical model, explaining why I expect organizational identification and SDO, above and beyond their main effects, to interact to produce derogation of out-group members. I then test this model empirically, using an in-basket exercise with a sample of Bogota, Columbia police officers. While the hypothesis were not supported with regards to behavioral mistreatment, mixed support was found with regards to out-group evaluations
