A Research Note on the Influence of Relationship Length and Sex on Preferences for Altruistic and Cooperative Mates

Previous literature suggests that altruism may have evolved as a sexually selectable trait. Recent research suggests that women seek altruistic traits for long-term, not short-term relationships, as altruism can serve as an honest signal of one’s character. We tested this hypothesis by asking 102 participants to complete a modified version of Buss’s Mate Preferences Questionnaire. We found that women placed higher importance on altruism in a mate compared to men, and this preference was greater when seeking a long-term, compared to a short-term mate. We also found that although women placed greater importance on cooperativeness in a mate compared to men, this preference was not influenced by whether they were seeking a short-term or a long-term mate. We successfully replicate previous literature exploring the role of altruism in mate choice.
