Blondes are contagious

When men meet fair-haired women they really do have a “blonde moment”. Scientists have found that their mental performance drops, apparently because they believe they are dealing with someone less intelligent.

Researchers discovered what might be called the “bimbo delusion” by studying men’s ability to complete general knowledge tests after exposure to different women. The academics found that men’s scores fell after they were shown pictures of blondes.

Further analysis convinced the team that, rather than simply being distracted by the flaxen hair, those who performed poorly had been unconsciously driven by social stereotypes to “think blonde”.
