"Gaydar" -- the purported ability to infer whether people are gay or straight based on their appearance -- seemed to get a scientific boost from a 2008 study that concluded people could accurately guess someone's sexual orientation based on photographs of their faces.
In a new paper published in the Journal of Sex Research, researchers at the University of Wisconsin-Madison challenge what they call "the gaydar myth." William Cox, an assistant scientist in the Department of Psychology and the lead author, says gaydar isn't accurate and is actually a harmful form of stereotyping.
