People tend to regard themselves as better than average. We conducted a replication and extension of Alicke’s classic study on trait dimensions in evaluations of self versus others with U.S. American Mechanical Turk workers in two waves (total N = 1,573; 149 total traits). We successfully replicated the trait desirability effect, such that participants rated more desirable traits as being more descriptive of themselves than of others (original: [Formula: see text] = .78, 95% confidence interval [CI] [.73, .81]; replication: sr 2 = .54, 95% CI [.43, .65]). The effect of desirability was stronger for more controllable traits (effect of Desirability × Controllability interaction on self–other-ratings difference; original: [Formula: see text] = .21, 95% CI [.12, .28]; replication: sr 2 = .07, 95% CI [.02, .12]). In an extension, we found that desirable traits were rated as more common for others, but not for the self. Thirty-five years later, the better-than-average effect appears to remain robust.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
