The study, published in the British Journal of Psychology, shows that altruists were found to have greater success in dating and sex.
Pat Barclay, a psychology professor at U of G, and Prof. Steven Arnocky from Nipissing, interviewed about 800 people about their relationships and propensity for helping others, including giving to charity, donating blood, helping strangers cross the street, donating winnings and helping classmates.
After controlling for age and personality, altruists were found to have greater success in dating and sex.
The study found that while altruism is desirable in both genders, it increases lifetime dating and sex partners for men more than for women.
The findings support previous studies on food sharing by hunters, which found that men who hunt and share meat enjoy greater reproductive success.
