Sex differences in jealousy and personality differences: Comparing consensually non-monogamous participants to a monogamous cohort
Year: 2022
Type: article
Study design: Observational Study
Abstract: Sex differences in jealousy are a well-established research finding that suggests men (relative to women) will find the sexual components of an infidelity more distressing, whereas women (relative to men) will find the emotional components of an infidelity more distressing. This study uses a relatively novel sample of participants (individuals who engage in consensual non-monogamy) to test both cultural and evolutionary influences on jealousy. In our study using hypothetical scenarios, we found that men (relative to women) were more upset about the sexual components of the infidelity and that women (relative to men) were more upset about the emotional components of the infidelity. This occurred in both samples to the same magnitude suggesting that the differences between the men and women may be driven by evolutionary influences. Additionally, we found a main effect of relationship type such that participants who engaged in consensual non-monogamy had lower levels of jealousy overall. As such, this study provides relatively unique evidence for the ultimate origins of sex differences in jealousy.
