Says Who? Credibility Effects in Self-Verification Strivings

Research shows that people prefer self-consistent over self-discrepant feedback—the self-verification effect. It is not clear, however, whether the effect stems from striving for self-verification or from the preference for subjectively accurate information. We argue that people prefer self-verifying feedback because they find it to be more accurate than self-discrepant feedback. We thus experimentally manipulated feedback credibility by providing information on its source: a student (control condition) or an experienced psychologist (experimental condition). In line with our expectations, the results of two preregistered studies with 342 adults showed that people preferred self-verifying feedback only in the control condition. In the experimental condition, the effect disappeared (or reversed, in Study 1). Study 2 showed that individual differences in credibility (epistemic authority) ascribed to the self and to psychologists matter as well. These findings suggest that feedback credibility, rather than the desire for self-verification, often drives the self-verification effect.
