Main Page | See live article | Alphabetical index Gaydar (the word is a pun on radar) is the supposed ability to be able to tell on sight if another person is gay, bisexual or otherwise a person who is not heterosexual. Many feel this term should not be used, as it reinforces stereotypes about homosexuals. This ability supposedly works by studying body language and picking up on stereotypes of what a lesbian, gay or bisexual person looks like. Some believe that, by making prolonged eye contact or by watching the subconsciously motivated behaviour of an individual, one can reliably detect another's sexual orientation, but there is no guarantee of success. No scientific study has absolutely verified that popular stereotypes are accurate enough to allow a person to reliably guess the sexual orientation of a stranger, although some studies suggest that one can have a limited ability to distinguish between homosexuals and heterosexuals.
