Evolution, Culture, and the Five-Factor Model

Abstract

Following areview of evolutionary approaches to the five-factor model (FEM), I develop a synthetic perspective that incorporates three levels of analysis: personality systems as universal psychological mechanisms, systematic group (i.e., gender, birth order, age, ethnic) differences that can be illuminated by evolutionary theory, and individual differences. At the level of universal mechanisms, personality systems are species-typical systems with adaptive functions in the human environment of evolutionary adaptedness. At the level of group differences, the evolutionary theory of sex, parent-offspring conflict theory, and life history are used to analyze sex, age, and ethnic differences in personality systems. At the level of individual differences, variation in personality consists of a range of viable evolutionary strategies for humans. Humans evaluate and act on the genetic and phenotypic diversity represented by this range of viable strategies to solve adaptive problems. Evolutionary perspectives on cross-cultural variation are noted and illustrated.
