The local dominance effect in self-evaluation: evidence and explanations.

The local dominance effect is the tendency for comparisons with a few, discrete individuals to have a greater influence on self-assessments than comparisons with larger aggregates. This review presents a series of recent studies that demonstrate the local dominance effect. The authors offer two primary explanations for the effect and consider alternatives including social categorization and the abstract versus concrete nature of local versus general comparisons. They then discuss moderators of the effect including physical proximity and self-enhancement. Finally, the theoretical and practical implications of the effect are discussed and potential future directions in this research line are proposed.
