Since the beginning of time, man has attempted to figure out how to tell if a woman or man is attracted to the same sex. If you listen to the gays, you would think that babies are born gay. But the truth is that humans and animals simply adapt psychosocially to our environments. In other words, we like what we like — whether what we like is a man, woman, child, or horse.

A new study reveals a sure-fire way to tell if someone is gay or straight: it’s all in the eyes.

According to Ritch Savin-Williams, a developmental psychologist at Cornell University, the pupils (the black circle in the center of our eyes) dilates when the subject looks at what he or she is attracted to. Savin-Williams says dilating pupils are an indication of sexual attraction.

So when a gay man, who says he’s straight, looks at a female — he might as well be looking at a blank wall; his pupils won’t dilate. But if he looks at another man, his pupils will increase slightly in size, which is an indication of sexual arousal.

This principle also applies to heterosexuals who look at each other. So the next time you’re in a club and you spy a chick who tickles your fancy, find a well-lighted spot in the club and look deep into her eyes before you spend wads of cash on drinks for her and her girlfriends.
