The New York Times:
“GAYDAR” colloquially refers to the ability to accurately glean others’ sexual orientation from mere observation. But does gaydar really exist? If so, how does it work?
Our research, published recently in the peer-reviewed journal PLoS ONE, shows that gaydar is indeed real and that its accuracy is driven by sensitivity to individual facial features as well as the spatial relationships among facial features.
We conducted experiments in which participants viewed facial photographs of men and women and then categorized each face as gay or straight. The photographs were seen very briefly, for 50 milliseconds, which was long enough for participants to know they’d seen a face, but probably not long enough to feel they knew much more. In addition, the photos were mostly devoid of cultural cues: hairstyles were digitally removed, and no faces had makeup, piercings, eyeglasses or tattoos.
Even when viewing such bare faces so briefly, participants demonstrated an ability to identify sexual orientation: overall, gaydar judgments were about 60 percent accurate.
