“Men agree a lot more about who they find attractive and unattractive than women agree about who they find attractive and unattractive,” says Wood, assistant professor of psychology. “This study shows we can quantify the extent to which men agree about which women are attractive and vice versa.”…

For example, women may encounter less competition from other women for the men they find attractive, he says. Men may need to invest more time and energy in attracting and then guarding their mates from other potential suitors, given that the mates they judge attractive are likely to be found attractive by many other men.

Wood says the study results have implications for eating disorders and how expectations regarding attractiveness affect behavior.

“The study helps explain why women experience stronger norms than men to obtain or maintain certain physical characteristics,” he says.
