Researchers have found we have an inbuilt ability to tell how intelligent a man is just by looking at them. The team from the Czech Republic found people were unable to perform the same deduction on women.
The team used static facial photographs of 40 men and 40 women to test the relationship between measured IQ, perceived intelligence, and facial shape.
Both men and women were able to accurately evaluate the intelligence of men by viewing facial photographs, they discovered.
The study, in the journal PLoS One, reports people tend to associate certain facial traits with high intelligence.
