We've all the heard the expression of having a "blonde moment" when we do something dumb. But researchers at the University of Paris say females with blonde hair cause men to act stupid.
The scientists found that men's scores on a general knowledge test dropped after looking at photos of blonde-haired women. The authors of the research say that when people are confronted with stereotypes, they generally follow them. Film stars like Marilyn Monroe, Paris Hilton and Anna Nicole Smith have only added to the blonde stereotype over the past half century according to the study.
