Intergroup bias — preference for one's in-group relative to out-groups — is one of the most robust phenomena in all of psychology. Here we investigate whether a positive bias that operates at the individual-level, belief in a good true self, may be leveraged to reduce intergroup bias. We find that even stereotypically threatening out-group agents are believed to have a good true self (Experiment 1). More importantly, consideration of an in-group and out-group members' true self reduces intergroup bias, both in the form of explicit evaluative judgments (Experiment 2) and actual donation behavior (Experiment 3). Across studies, the palliative effects of thinking of an individual's true self generalize to that individual's entire group. In sum, a simple intervention — thinking about another's true self — reduces the gap in how people evaluate and treat out-group relative to in-group members. We discuss implications of these findings for conflict reduction strategies.
