Have you heard of “gaydar?” It’s common homophobic term used by heterosexuals to detect whether or not a person is part of the LGBTQ crowd. Living in Atlanta, the unofficial capital of the down-low black man, I know women who feel they always need an updated version of gaydar, mainly to protect themselves against the very real threat of HIV, but mostly so they can deflect responsibility off their bad decisions by blaming their imaginary anti-gay security system.

Well research has caught up to this gaydar idea and fleshed out another way to detect gayness. A new study found that pupil dilation is an accurate indicator of sexual attraction, and since it’s involuntary, it could be used to determine what gender a person is attracted to.

A Cornell University study published this month in the journal PloS ONE analyzed the pupil dilation of 325 men and women who were faced with sexually arousing images.
