Sex differences (and similarities) in jealousy: The moderating influence of infidelity experience and sexual orientation of the infidelity

Past demonstrations of sex differences in jealousy have generally employed Buss et al.’s [Psychol. Sci. 3 (1992) 251] forced-choice methodology, a limitation criticized by DeSteno and Salovey [Psychol. Sci. 7 (1996) 367]. The present studies address this criticism by demonstrating the sex difference using both forced-choice and continuous measures of jealousy. In addition, the results distinguish two important moderators of the sex difference: infidelity experience, in which male victims and female perpetrators of infidelity reported greater distress in response to a sexual infidelity, and sexual orientation of the infidelity, in which the sex difference disappears completely when an infidelity carries no risk of conception because an opposite-sex partner has become involved with a same-sex lover.
