In a new study, both male and female subjects were able to accurately evaluate the intelligence of men simply by viewing photographs of their faces.
While many avow that you can't judge a book by its cover, researchers Karel Kleisner, Veronika Chvátalová, and Jaroslav Flegr, all based out of Charles University in the Czech Republic, showed that if that book is a man, you probably can.
For the study, which is published in PLoS ONE, 80 science students from Charles University -- 40 men and 40 women -- took an in-depth exam to gauge their IQ and were subsequently photographed with neutral face expressions. Another 160 participants assessed the photographs, judging the subjects' attractiveness and intelligence on a scale of 1 (the highest ranking) to 7 (lowest ranking).
......So why could both men and women accurately predict the intelligence of men, but not women, based on their looks?
One explanation the researchers put forth is that physical cues of intelligence may be sexually dimorphic. So while intelligence may be physically plastered on the faces of men, women may signal it in other ways.
