A new study published in Evolutionary Psychological Science suggests that men are somehow wired to focus on the upper body aspects of other men – such as the chest and shoulder regions, more than women are.
“Men and women have sexually dimorphic physical characteristic and both men and women rate female faces bearing feminine features, such as full lips and small chin, more attractive than female faces with masculine traits,” said Farid Pazhoohi, a psychologist based at the University of British Columbia and the corresponding author of the new study.
“Similarly, individuals prefer female-typical body features such as low waist to hip ratios (small waist and broad hips) in women compared to masculine features (high waist to hip ratios). One male-typical sexually dimorphic trait is broad chests (larger upper body size) and is associated with being more successful with securing status and resources.”
“If having a larger upper body is a male-typical attribute, then women with smaller upper bodies should be considered more feminine and therefore more attractive. Similar to men, women’s body characteristics such as their upper body size show variations,” Pazhoohi told PsyPost.
“As the variations in women upper body have never been investigated, we aimed to test the effect of both men and women upper body size on their perceived attractiveness and gazing behavior in both men and women.”
