Gay People Look Different, Walk Different Than Straight People

Body shape, mannerisms and the way one walks are indicators of sexual orientation, according to a new study from the Journal of Personality and Social Psychology. Uh, duh! We've been subscribing to the whole "if it looks like a duck and walks like a duck" thing for, like, forever, but we suppose that we feel a bit more validated now that it's all scientific or whatever. But you don't even have to be a scientist to pass such judgments:

We've found that casual observers can use gait and body shape to judge whether a stranger is gay or straight with a small but perceptible amount of accuracy.
Interestingly, it's easier to read such cues in gay men than lesbians. As for body types, gay people tend to possess "gender-incongruent" shapes—hourglass for gay dudes and "tubular" for lezzies.

One of the best parts of the study was that over 100 "casual observers" got to stare the asses of the study's participants as they walked on a treadmill.

The observers were able to determine the volunteers' sexual orientation with an overall rate of accuracy that exceeded chance, even though they could not see the volunteers' faces or the details of their clothing.
It could be said that such a study is potentially dangerous, as it sort of reinforces judging a book by its cover, which is something we've always been told we're not supposed to do. However, the life you live is inscribed upon your body and they way you present yourself, so it only makes sense that we give aspects of ourselves away before we even say a word.
