Self-Affirmation and Prejudice Reduction: When and Why?

The question of the antecedents of prejudicial responses has a long history that includes contributions of historical, structural, cultural, and psychological factors. Social-psychological research on prejudice as self-image maintenance provides evidence that manifestations of prejudice stem, in part, from the motivation to maintain a feeling of self-worth and self-integrity. Here, we review studies that indicate when and why prejudice toward out-groups in response to self-threats is weakened by affirmations of self-worth. A distinction emerges between in-group threats (e.g., negative acts committed by the in-group) and out-group threats (e.g., immigrants) to social identity, on the one hand, and the defensive reactions people make in response to each kind of threat (i.e., denying in-group responsibility vs. displaying prejudice), on the other. Such negative intergroup interactions can be attenuated by affirming the self. We present theorized moderators (i.e., individual differences and cultural norms) and proposed mechanisms underlying affirmation effects in the domain of prejudice. We discuss potential applications of self-affirmation in prejudice-reduction efforts.
