Self-enhancement and belief perseverance

Belief perseverance-the tendency to make use of invalidated information-is one of social psychology's most reliable phenomena. Virtually all of the explanations proffered for the effect, as well as the conditions that delimit it, involve the way people think about or explain the discredited feedback. But it seems reasonable to assume that the importance of the feedback for the actor's self-image would also influence the tendency to persevere on invalidated feedback. From a self-enhancement perspective, one might ask: Why would people persist in negative self-beliefs, especially when the basis for those beliefs has been discredited? In the present study, actors and observers completed a word-identification task and were given bogus success or failure feedback. After success feedback was discredited, actors and observers persevered equally in beliefs about the actor's abilities. However, following invalidation of failure feedback, actors provided significantly higher performance evaluations than observers, thus exhibiting less perseverance on the negative feedback. These results suggest that the motivation to maintain a relatively favorable self-image may attenuate perseverance when discredited feedback threatens an important aspect of the self-concept.
