Peering Into the Bias Blind Spot: People’s Assessments of Bias in Themselves and Others

People tend to believe that their own judgments are less prone to bias than those of others, in part because they tend to rely on introspection for evidence of bias in themselves but on their lay theories in assessing bias in others. Two empirical consequences of this asymmetry are explored. Studies 1 and 2 document that people are more inclined to think they are guilty of bias in the abstract than in any specific instance. Studies 3 and 4 demonstrate that people tend to believe that their own personal connection to a given issue is a source of accuracy and enlightenment but that such personal connections in the case of others who hold different views are a source of bias. The implications of this asymmetry in assessing objectivity and bias in the self versus others are discussed.
