By having test subjects, some gay, some straight, study a series of shapes and patterns, the researchers found that gay folks pay more attention to detail. Thus, they might be able to pick up small cues about a person’s sexuality.

Researcher Dr Lorenza Colzato, of Leiden University in the Netherlands, said: ‘This is the first time that scientific proof has been found for the existence of a gaydar mechanism amongst homosexuals. This perceptual skill allows homosexuals to recognise other gay people faster and we think it’s because they are much more analytic than heterosexuals.’ Adopting such a perceptual style presumably increases the likelihood of detecting perceptual clues indicative of homosexual orientation, which facilitates finding like-minded social peers and potential friends and sex mates
