I think society would do well to recognize what some of those studies showed, rather than constantly trying to suppress it as a superficiality. Truth is that most human motivation, behavior, and cognition is really rather base and painfully simple, especially in the arena of romance.
Researchers note that women perceive men with beards as having “the biological and social qualities that would enhance their value as husbands” and also consider them “more potent and more active, suggesting virility as well as physical attractiveness.” Additionally, female managers considered bearded men to be more competent. Male bosses, however, did not.
I liked this one. I'm not a beard man but I do furnish a trimmed scruff, and I would never go completely shaven for anyone. I can see guys over 40 doing it, because they need to look younger, but the tradition of doing it when you're under 40 to look "clean-cut," a tradition started with the Romans I believe, just doesn't seem manly. Sure if you have a really chiseled jaw you can get away with it, but most of us are complimented better by having the jaw defined by some scruff.
