  19. > Our findings demonstrate that infidelity and number of sexual partners are both under moderate genetic influence (41% and 38% heritable, respectively) and the genetic correlation between these two traits is strong (47%). The resulting genetic correlation between the two traits was .47, so nearly half the genes impacting on infidelity also affect number of sexual partners. The correlation of the unique environment between the two variables was .48.

  25. > A truism in psychology is that the best predictor of future behavior is past behavior. This is no less true in the realm of sexual behavior. Indeed, one of the strongest predictors of marital infidelity is one’s number of prior sex partners (Buss, 2000). Deception about past sexual promiscuity would have inflicted greater costs, on average, on men than on women

  31. > The high correlation for females (r = .79) between reported numbers of sex partners and EPC partners [extra-pair copulation partners *def*. sexual partners other than primary partner while in a monogamous relationship] may bear on questions of both paternity and abandonment in the face of infidelity. Throughout recent human history, males have often placed a premium on female virginity for a marital partner (e.g., Ford & Beach, 1951). This is commonly thought to be an expression of a paternal assurance strategy, i.e., sexually inexperienced females are assumed to represent a lower risk of cuckoldry.

  35. > But the question remains: does promiscuity predict infidelity? Our data are consistent with those of Essock-Vitale and McGuire (1985) in suggesting that a substantial proportion of the variance in infidelity can be accounted for in terms of number of sex partners, but this conclusion is compromised by the fact that the number of sex partners is confounded with the number of EPC partners. To correct for this, we subtracted reported EPC partners from total reported sex partners for each respondent to create an estimate of promiscuity apart from EPCs. The resultant number (reported non-EPC sex partners) was still highly correlated with number of EPC partners (females: r = .67, n = 56, P < .01), suggesting that promiscuity is in fact a good predictor of infidelity. Indeed, promiscuity among females accounted for almost twice as much variance in infidelity (r^2 = .45) as it did for males (r^2 = .25).

  41. > Sexual promiscuity was significantly positively correlated with emotional promiscuity [r(356) = .261, p < .001], as well with sexual infidelity [r(323) = .595, p < .001] and emotional infidelity [r(323) = .676, p < .001], indicating that sexually promiscuous participants also tend to be emotionally promiscuous, and sexually and emotionally unfaithful. In terms of the sexual domain, results showed that there is also a positive correlation between sexual promiscuity and sexual infidelity, stating that individuals that tend to be more sexually promiscuous also tend to be more sexually unfaithful. These results support our second hypothesis.

  67. > For people in this survey who reported four or fewer lifetime sexual partners, the rate of infidelity in the current marriage dropped to 11%, while for those who had five or more sexual partners the number was nearly double (21%). The break between the 54% of people who had five or more lifetime sexual partners vs. the 46% who had four or fewer total partners illustrates the lessons from the study. This breakpoint is validated by the fact that when asked straight out, 68% of those with more sexual partners in their pasts agreed that, “I am always faithful to my sexual partner” (whether currently married or single), compared to 82% of those with fewer sexual partners who said the same.
