Self-Threat Magnifies the Self-Serving Bias: A Meta-Analytic Integration

Experiments testing the self-serving bias (SSB; taking credit for personal success but blaming external factors for personal failure) have used a multitude of moderators (i.e., role, task importance, outcome expectancies, self-esteem, achievement motivation, self-focused attention, task choice, perceived task difficulty, interpersonal orientation, status, affect, locus of control, gender, and task type). The present meta-analytic review established the viability and pervasiveness of the SSB and, more important, organized the 14 moderators just listed under the common theoretical umbrella of self-threat. According to the self-threat model, the high self-threat level of each moderator is associated with a larger display of the SSB than the low self-threat level. The model was supported: Self-threat magnifies the SSB.
