Study Finds ‘Gaydar’ Up to 80 Percent Accurate on Sexuality

"Gaydar," the ability to detect sexual orientation as if through radar, is real. And some people can guess with 80 percent accuracy, according to a new study.

In a study of college students at the University of Washington, most people were able to identify a person’s sexuality with greater-than-chance accuracy based on black-and-white photo flashes of them for just 50 milliseconds—faster than the blink of an eye, US News reports.
