Why do blondes stare at orange juice containers for hours on end? Because they say "concentrate." Ba Dum Tss.

I have heard my fare share of blonde jokes while growing up. So often, blonde hair is associated with being dumb—as if one's intelligence is directly related to the color of their hair. I never understood why blondes were assumed to be "bimbos," but then again I am a blonde, so maybe that's why I can't comprehend it, right? Wrong.

According to a study conducted by Jay Zagorsky from Ohio State University, the average IQ for blonde women was actually the highest when compared to the average IQ of women with brown, red and black hair. Today, there are many powerful blonde women that are breaking the dumb blonde stereotype.
