Dispositional bases of self-serving positive evaluations

Positive orientation (POS) is the name given to the latent dimension common to self-esteem, optimism and life satisfaction. Earlier findings attest to the trait-like nature of POS and to its unique contribution to well-adjustment across domains of functioning. The present study investigates the extent to which POS accounts for individuals' tendency to distort their self-assessment in a positive direction. Taking a class of students (N = 190) at the beginning of their academic year, POS predicted the individuals' tendency to perform academically better-than-average (BTA) peers. POS accounted for BTA beyond what is merely due to self-esteem, life satisfaction and optimism.
