Sex Differences in Mate Preferences Across 45 Countries: A Large-Scale Replication

Summary

This large-scale study set out to replicate classic findings on sex differences in human mate preferences using a new, geographically diverse sample. Data were collected from 14,399 participants across 45 countries, allowing a rigorous test of whether previously reported patterns hold cross-culturally. The authors compared predictions from an evolutionary psychological perspective against those of a biosocial role perspective. Consistent with prior work, men more than women preferred mates who were younger and physically attractive, while women more than men preferred mates who were older and had good financial prospects. These sex differences emerged robustly across cultures, supporting the replicability of the core preference patterns while informing the debate between competing theoretical accounts.
