Study Debunks Monogamy Superiority, Finds Equal Happiness in Diverse Relationship Styles
March 26, 2025
A recent study published in The Journal of Sex Research reveals that individuals in both monogamous and non-monogamous relationships report similar levels of happiness and satisfaction.
The research analyzed 35 previous studies involving nearly 25,000 participants from the United States, Australia, and Europe, challenging the long-held belief in the superiority of monogamous relationships.
Lead author Joel Anderson from La Trobe University points out that societal stereotypes and media narratives often perpetuate the 'monogamy-superiority myth'.
Non-monogamous relationships can provide individuals with opportunities to meet diverse emotional and physical needs, promoting personal growth and autonomy.
The rise of hookup apps has sparked increased discussion around non-monogamous relationships, despite some backlash favoring traditional monogamous ideals.
Researchers advocate for a more inclusive perspective on relationship structures, urging health professionals and policymakers to support diverse relationship forms rather than defaulting to monogamy as the ideal.
However, the study does have limitations, including a lack of consideration for the types of non-monogamous relationships and potential biases in self-reported data.
The researchers suggest that the openness and communication required in non-monogamous relationships may enhance overall relationship satisfaction, despite societal stigma.
Conducted primarily in Western contexts, the study indicates a growing acceptance of various relationship models, particularly among younger generations.
A 2022 report noted that approximately 6% of Australians have engaged in open relationships, suggesting a potential rise in the popularity of non-monogamous relationship types.
Dr. Anderson emphasizes that the focus should be on communication and connection rather than the structure of the relationship itself.
Ultimately, this analysis challenges the notion that monogamous relationships are inherently more fulfilling, advocating for recognition of diverse relationship possibilities.
