Women who are ovulating are much better at guessing whether a man is gay or straight, according to a new study from researchers at the University of Toronto and Tufts University.
Scientists asked 40 heterosexual female students to judge 80 photos of men’s faces. Half of the men were gay and the rest were straight, but the groups were considered equally attractive. What’s interesting is that women judged the sexual orientation of each man more accurately during ovulation.
“What it really sort of hints at is [that] there are evolutionary reasons why women would pay attention to cues relevant for mating,” Nicholas Rule, a lead researcher, told The Toronto Star. “When women have a higher chance of getting pregnant they’re going to pay more attention to cues in the environment that would attend to that.”
