Makes sense to me — if not for the pronounced lower jaw, for the manly (read: non-juvenile) look a bit of stubble provides. Oddly enough, this thought had crossed my mind in a comment on Patri’s LJ almost right before I found this article. And of course, I’ve blogged on shaving before.
Women participating in the research rated men with stubble as tough, mature, aggressive, dominant and masculine – and as the best romantic partners, either for a fling or a long-term relationships. The findings of the experiment, carried out on British women aged 18 to 44, could explain the appeal of actors such as George Clooney and Brad Pitt who cultivate their unshaven look. The explanation for the preference is not clear, but experts in human evolution say that that facial hair may be a signal of aggression because it boosts the apparent size of the lower jaw, emphasising the teeth as weapons. Psychologists at Northumbria University who carried out the new study believe that stubbly men may offer women the best worlds – not too strongly masculine, but mature and with the potential to grow a full beard.
