New study challenges the ‘monogamy-superiority myth’, as non-monogamous people report just as happy relationships and sex lives

A comprehensive meta-analysis of 35 studies involving 24,489 people across the U.S. and Europe found no significant differences in relationship or sexual satisfaction levels between individuals in monogamous and non-monogamous relationships. Non-monogamy is often viewed as inferior to monogamy due to stereotypes and media narratives.

Polygamy is (not) for the birds

Lekking, a mating system where males display for females without forming lasting bonds, is found to be remarkably stable and rarely evolves into other systems. In contrast, resource-defense polygamy is identified as fragile and frequently reverts to monogamy, often associated with higher extinction rates.

Do open relationships really work?

A team from the University of Rochester found that non-monogamous relationships succeed when all parties are comfortable with each other. Monogamous and consensual non-monogamous groups reported high levels of functioning in their relationships, while partially open and one-sided non-monogamous groups showed lower levels of functioning.

Evolution of monogamy in humans the result of infanticide risk

The study reveals that male infanticide is the key driver of monogamy in humans and other primates. By caring for young, fathers can protect infants from rival males and share childcare burdens. This leads to a reduction in infant dependency and allows females to reproduce more quickly.
