A comprehensive international study has confirmed that female faces are generally rated as more attractive than male faces across diverse cultures, lending support to a hypothesis first proposed by Charles Darwin more than 150 years ago. The research, involving tens of thousands of participants and thousands of facial images, demonstrates a consistent pattern in attractiveness judgments worldwide.

Led by Dr. Eugen Wassiliwizky of the Max Planck Institute for Empirical Aesthetics in Germany, the analysis combined data from 52 studies conducted in 76 countries. In total, approximately 28,500 individuals rated the attractiveness of around 17,000 facial photographs. The findings revealed that, on average, women’s faces received higher attractiveness scores than men’s. Interestingly, female raters assigned even stronger preferences for women’s faces compared to male raters.

“This pattern, where women give the highest ratings to other women and the lowest ratings to men, was unexpected,” Dr. Wassiliwizky noted. The outcome adds new depth to ongoing discussions about human mate choice and aesthetic preference, areas that have been central to evolutionary biology since Darwin’s time.

Darwin introduced the concept of sexual selection to explain why some animals develop features that appear disadvantageous for survival but advantageous for attracting mates, such as the male peacock’s elaborate tail. Typically, in many species, males possess more conspicuous traits to appeal to females. However, Darwin observed that humans seemed to display the opposite trend, with females more commonly considered the more attractive sex. Until now, empirical confirmation of this phenomenon on a global scale was limited.

While the study affirms that human females are broadly perceived as more attractive, it does not resolve why this pattern diverges from many other species. The researchers propose several potential explanations. One possibility is that women may be more attuned to recognizing female beauty or more generous in their assessments. Another is the influence of cultural factors, including socialization processes, media, and advertising, which often place a pronounced emphasis on female appearance and associate beauty closely with femininity.

The study emphasizes that judgments of facial attractiveness extend beyond simple heterosexual mate preference, reflecting more complex social and perceptual dynamics. However, the exact contributions of biological and cultural factors remain unclear, highlighting the need for further investigation to understand the interplay shaping human perceptions of beauty.
