We judge you by your facial hair

Rookie Bryce Harper of the Washington Nationals is a polarizing figure in baseball today, mostly due to his attitude. But recent discoveries in social psychology suggest our perceptions of Harper may be shaped by something a little hairier: the kid's facial hair.

Rookie Bryce Harper, all of 19 years old, has such a poor rep already in Major League Baseball that Cole Hamels felt justified in hitting him with a fastball, and then bragging about it afterwards, as Jelisa Castrodale of NBCSports.com points out.

Apparently there could be a number of reasons to explain the visceral reaction to Harper, including a propensity toward arrogance. But could the kid’s facial hair have anything to do with it?

Sounds bizarre, but maybe.

Last January, in the journal Behavioral Ecology, two researchers, Barnaby Dixson of Victoria University in Wellington, New Zealand, and Paul Vasey, of the University of Lethbridge in Alberta, Canada, released a study on reactions to men’s beards.They pointed out that beard growth is under genetic control, and that it may serve as a sexual signal between men. In tests, women in both Samoa and in New Zealand did not rate bearded men as any more attractive than the same men pictured without beards, so beards weren’t helping the guys get girls. But other men (women, too) viewed bearded male faces as more threatening when the pictured males adopted an angry look.

Facial hair, the authors wrote “may intimidate rival males by increasing perceptions of the size of the jaw, overall length of the face, and by enhancing aggressive and threatening jaw-thrusting behaviors ... . The current study is the first to show that the beard augments a threatening behavioral display as bearded men with angry facial expressions received significantly higher scores for aggressiveness compared with clean-shaven faces ... . This suggests that the beard plays an important role in intermale signaling of threat and aggression." More >>
