Both Hostile and Benevolent Sexism Predict Men’s Infidelity

Infidelity has destructive effects on romantic relationships. Several idiographic characteristics or experiences in an intimate relationship have been linked to unfaithfulness. Yet, relatively little research has been paid to investigate how sexist beliefs might sabotage relationships by incurring infidelity. The present research examined the association between men’s ambivalent sexism – hostile sexism and benevolent sexism – and men’s infidelity as well as women’s perception of the likelihood of men’s infidelity. The results showed that men’s hostile sexism and benevolent sexism predicted their increased infidelity (Studies 1 and 2). In addition, the indirect association between ambivalent sexism (both hostile sexism and benevolent sexism) and infidelity was through the importance placed on power in one’s intimate relationship in general (Study 2). Importantly, women were unaware of benevolently sexist men’s increased infidelity, such that women rated benevolently sexist men as having a lower likelihood of engaging in infidelity than hostilely sexist men and believed benevolently sexist men’s infidelity level was similar to nonsexist men (Study 3). Therefore, these findings contribute to the psychology of infidelity by revealing that ambivalent sexism, both hostile sexism and benevolent sexism, are significant predictors. Implications of the findings are discussed. © 2024 The Society for the Scientific Study of Sexuality.
