Sexual strategies theory: Historical origins and current status

Abstract

In sexually reproducing organisms, no domain is more closely linked with the engine of the evolutionary process than sexuality. Men and women over human evolutionary history have confronted different adaptive problems in the sexual domain. Sexual Strategies Theory offers an account of these adaptive problems and presents a view of human sexual psychology as a rich repertoire of mechanisms that have evolved as adaptive solutions. A host of specific predictions about human sexuality follows from this analysis, including an account of sex differences in the desire for sexual variety, the qualities preferred in short‐term and long‐term mates, context‐dependent shifts in mate preferences, the nature of sexual jealousy, the tactics that are effective for attracting and retaining a mate, and the causes of sexual conflict between men and women. After reviewing the theory's historical origins, I summarize a portion of the extensive empirical research designed to test its tenets. An evaluation of the theory notes its strengths as well as its weaknesses, with a special focus on the issues of prediction and falsification. It ends with a challenge for other theories of human sexuality to reach an equivalent level of specific predictions, a comparable empirical foundation, an equally parsimonious account of sex differences, a compelling ultimate account of causal origins, and a comparable level of multi‐level conceptual integration.
