Altruistic People Have More Sex

After crunching the numbers, the researchers found that altruistic behavior “significantly predicted” self-reported mating success and lifetime number of sexual partners, and that it was “modestly related” with sex within a relationship. The researchers also found that altruism had a stronger link to casual sex partners for men compared to women. In a second study of 335 undergraduate women and 189 undergraduate men, participants did self-reports on desirability, sexual history, and personality. They were also presented with a hypothetical situation: If they were to win a $100 raffle, would they keep the money, donate it to charity, or do some combination of the two? In line with the first study, the second found that donating “significantly predicted” the number of people someone had slept with over their lifetime.
