And it's an important scientific fact and we need to understand it better,' Bailey said. 'On average gay men are more feminine in certain ways than straight men. Some gays have criticized Bailey, saying he's just perpetuating the stereotype that gays are effeminate. * Straight men tend to slouch, gay men tend to sit a little more neatly. Gay men do more movements from their elbows down. * Straight men tend to move in their arms from their shoulders more. In his book, 'The Man Who Would Be Queen,' he gives reasons why. Even when all they saw was a 10-second videotape, or just listened to the subjects' voices, they were right about who was gay more often than not.

On average people do far better than chance,' said Bailey.īailey's more scientific tests found graders to be accurate more than 70 percent of the time. But they were 60 percent correct - better than chance. Had they made random guesses, they would have been 50 percent right. On the whole, the testers did pretty well. It wasn't a scientific test, but Northwestern University psychology professor Michael Bailey, who has done scientific tests of gaydar, said the test was valid. No one was allowed to ask any direct questions about sexuality.
