It's Official: Blondes Have a Higher Average IQ Than Brunettes

It’s time to put all those sexist and idiotic “dumb blonde” jokes into retirement forever, because new evidence suggests that not only are blondes just as intelligent as anyone else — they actually have a higher average IQ than women with other hair colors.

Yep, seriously. Researchers from Ohio State University analyzed data of 10,878 Americans, finding that women who claimed to be natural blondes had an average IQ score within three points of brunettes, redheads and raven-haired women.

But it gets better: They also learned the average IQ of blonde women was a tad bit higher than ladies with other hair colors — 103.2, compared to 102.7 for brunettes, 101.2 for redheads and 100.5 for those with black hair. Sure, the difference isn’t statistically significant, but it finally puts to bed the ridiculous stereotype that blonde hair is somehow related to low intelligence.

“I don’t think you can say with certainty that blondes are smarter than others, but you can definitely say they are not any dumber,” explains Jay Zagorsky, lead author of the study.

While blonde jokes can seem harmless to many, they can in fact have real-world repercussions. “Research shows that stereotypes often have an impact on hiring, promotions and other social experiences,” Zagorsky said. “This study provides compelling evidence that there shouldn’t be any discrimination against blondes based on their intelligence.”

So the next time you hear a nonblonde kick-start a conversation with one of those “so a blonde walks into a bar” lines, kindly let ’em know the joke is on them.

Science has got your back!

What Do YOU Think?

Are you surprised that blondes may be smarter than people with other hair colors Do you think hair color makes a big difference when it comes to someone’s intelligence or personality? Do you think the results would be different if researchers looked at people who dyed their hair blonde versus natural blondes?
