The first group rated the men’s beardless-to-bearded faces for overall sexual attractiveness.
The second group also rated the photos, but this time they were asked to score the pictures based on short-term attractiveness: Which of the men seemed most desirable for a fling or a one-night stand?
The third group rated the men in the photos as long-term prospects: Which of the men had a face that suggested he might be a good candidate for marriage and commitment?
The answers, which were published in the Journal of Evolutionary Biology, varied depending on what the woman was looking for. Overall, the women said the sexiest men were those sporting heavy stubble, followed by short stubble. Men with full beards and clean-shaven men were rated the lowest on the overall sexiness scale.
