Researchers who study perspective taking are generally optimistic about the potential for interventions to improve intergroup perceptions. The current research provides new insight into the conditions that frame the intergroup outcomes of perspective taking. The results show that the effects of perspective taking are not always positive but depend on perspective takers' degree of identification with the in-group. In two experiments, we demonstrated that adopting the perspective of an out-group member can have damaging effects on intergroup perceptions among group members who are highly identified with the in-group. Specifically, compared with less committed members, those who identified highly with the in-group used a greater number of negative traits to describe the out-group following perspective taking. Such perspective taking also led participants with high in-group identification to judge the out-group less favorably. Understanding how social identity concerns frame the outcome of perspective taking is crucial to its effective employment in intergroup-relations programs.
