Well, if you put 1000 people through a study where they watch videos of people and where they are supposed to figure out who's gay or not and the success rate is on average something like 80~90% (just making up numbers here), then doesn't that indicate that most people may have some kind of "gaydar"?
Of course - how it works, where the clues come from, whether it's body language or the way people talk or look .. figuring that out would just explain how the gaydar works, not that it doesn't exist.
