seattle-pk writes "Males are apparently clueless when it comes to interpreting sexual intent from females, according to a recent study (PDF) from Indiana University's Department of Psychological and Brain Sciences. Men were found commonly to perceive more sexual intent in women's behavior than women were intending to convey. (A campus survey showed that 68% of college females had an experience where a male mistook signs of friendliness for affection.) However, the study also shows that men were quite likely to misperceive sexual interest as friendliness. 'Rather than seeing the world through sex-colored glasses, men seemed just to have blurry vision of sorts, overall,' according to the article. If you're a male who ever mistook the meaning of a barista's smile, looks like you're not alone."
