"A note to single dudes: If you're looking to pick up a woman at a bar, whatever you do -- don't smile at her. Women are actually less sexually attracted to smiley, happy men, suggests a new University of British Columbia study, published online today in the journal Emotion. If that's surprising to you -- it was surprising to lead researcher Jessica Tracy, too. "I wouldn’t have believed it if we didn’t go out and replicate it three times," says Tracy, an assistant psychology professor at UBC. Researchers asked more than 1,000 volunteers to rate the sexual attractiveness of hundreds of images of the opposite sex. (All were heterosexual, ages 17 to 49 years, with a median age of 21. Fifty-two percent of participants were Asian, and 48 percent were Caucasian.) In the images, the men and women pictured were demonstrating one of three emotions: happiness, pride or shame -- plus a "neutral" image thrown in there, too. They found that women ranked the smiling guys as less attractive -- but they were into the prideful and ashamed men.
