I Know (What) You Are, But What Am I? The Effect of Recategorization Threat and Perceived Immutability on Prejudice.

Learning one is similar to a stigmatized group can threaten one's identity and prompt disassociation from the group. What are the consequences of learning of a similarity to a stigmatized group when that similarity implies possible recategorization into the group? We investigated how learning of an immutable, recategorization implying similarity with an outgroup affects implicitly and explicitly assessed prejudice. In Study 1, White participants who believed they had above average genetic overlap with African Americans showed decreased prejudice on implicit but not explicit measures. In Study 2, straight/heterosexual participants who were led to believe they exhibited some same-sex attraction showed reduced implicitly assessed prejudice, but only if they believed sexual orientation was biologically determined. Thus, learning of an identity-implying similarity with an outgroup can reduce implicit prejudice if that group membership is believed to be immutable. Theoretical and practical implications are discussed.
