Evolution, sex, and jealousy: Investigation with a sample from Sweden

When asked to choose which would be most upsetting, a mate's sexual or emot ional infidelity, past research has demonstrated that men are more likely t han women to choose sexual infidelity, whereas women are more likely than m en to choose emotional infidelity. Explanation of this sex difference has b een controversial. In the current study we attempted to replicate previous research by examining a sample of college students in Sweden. In doing so, we also investigated the "double-shot" explanation, In the current study, t he majority of men chose the sexual infidelity scenario las most upsetting, whereas the majority of women chose the emotional infidelity scenario as m ost upsetting, Contrary to the double-shot explanation, choice of scenario was unrelated to attitudes regarding whether the other sex was capable of s atisfying sexual relations outside of a love relationship.
