Whose Life Do You Save? Factors Associated With Gender Differences in Altruism Toward Romantic Partners Versus Genetic Relatives

Abstract

This study explored potential gender differences in altruism in three hypothetical life-or-death situations in which a romantic partner and a relative (an offspring, a sibling, and a cousin) were involved. Specifically, 200 college students (93 men) responded to a 24-item questionnaire: 12 items focused on the three romantic partner versus relative life-or-death dilemmas; 12 items served as control items and focused on three relative versus relative life-or-death dilemmas (sibling vs. offspring; sibling vs. cousin; cousin vs. offspring). For each main dilemma, four different versions were created by varying the ages of both romantic partners and genetic relatives. Overall, the participants saved their offspring and siblings more often than their romantic partners, and their romantic partners more often than their cousins. In all three dilemmas, the proportion of women who saved their genetic relative over their romantic partner was significantly higher than the proportion of men, with the age of both romantic partners and relatives playing a role. Romantic partners were significantly saved more often when pitted against their cousins than when pitted against their siblings, and when pitted against their siblings than when pitted against their offspring. Young adult males and females exhibit minor, but significant and consistent, gender differences in their altruistic tendencies toward relatives in hypothetical critical situations in which other close non relatives, namely romantic partners, are also involved.
