The bias blind spot: Perceptions of bias in self versus others

Three studies suggest that individuals see the existence and operation of cognitive and motivational biases much mare in others than in themselves. Study 1 provides evidence from three surveys that people rate themselves as less subject to various biases than the average American, classmates in a seminar, and fellow airport travelers. Data from the third survey further suggest that such claims arise from the interplay among availability biases and self-enhancement motives. Participants in one follow-up study who showed the better-than-average bias insisted that their self-assessment is were accurate and objective even after reading a description of how they could have been affected by the relevant bias. Participants in a final study reported their peer's self-serving attributions regarding test performance to be biased but their own similarly self-serving attributions to be free of bias. The relevance of these phenomena to naive realism and to conflict, misunderstanding, and dispute resolution is discussed.
