The current study compared physical aggression to factors affecting socioeconomic status in the accumulation of sex partners over the life course. Our data sample was drawn from the National Longitudinal Study of Adolescent to Adult Health (men, n = 5,636; women, n = 6,787). Participants were examined in terms of the number of lifetime sex partners they reported, nonrelationship partners, cheating or infidelity, and concurrent relationships. Intelligence and physical violence emerged as being especially likely to boost sex partner accumulation for the number of lifetime sex partners and nonrelationship partners in men. Intelligence also interacted positively with men's violence in cross-sectional models but not longitudinally. Women's violence was not significant regardless of the outcome or model specification. Intelligence showed less consistent effects for women's mating indicators compared to men. Analyses controlled for well-known correlates of aggression and sexual behavior and factors associated with beauty, including interviewer reports of survey participants' physical attractiveness and maturity, as well as self-reported attractiveness, maturity, and health. Findings are consistent with evolutionary ideas regarding costly signaling as an effective mating strategy among men.
