Life History strategy and Evaluative Self-Assessment

Abstract

Life History (LH) theory describes the existence of individual differences in the optimal allocation of inherently limited bioenergetic and material resources towards different types of reproductive-enhancing activities. LH theory predicts that slow LH (“High- K”) individuals are biased toward allocating resources toward enhancing the phenotypic quality (e.g., physical and mental health) of oneself and one’s offspring. Sociometer theory suggests that self-esteem tracks an individual’s level of social acceptance and inclusion. We examined the hypothesis that slow LH strategy positively predicts a more positive Evaluative Self-Assessment due to enhanced phenotypic quality. Participants completed questionnaires measuring their Life History (LH) strategies and a variety of measures of Self-Assessment (perceived mate value, perceived mating success, social economic exchange, positive and negative adjectives, global self-esteem, and collective self-esteem). An Exploratory Factor Analysis indicated that the measures of Evaluative Self-Assessment were best represented as a single latent factor. Slow LH strategy correlated moderately and positively with this Evaluative Self-Assessment factor. This relationship was not accounted for by socially desirable responding (self-deceptive enhancement or impression-management), sex, or age of participants. Consistent with Sociometer theory, we suggest that slow LH strategists exhibit high perceived self-worth due to increased social prestige and, relatedly, enhanced phenotypic quality.
