OSU Researcher Disproves “Dumb Blonde” Urban Myth

The study of 10,878 Americans found that white women who said their natural hair color was blonde had an average IQ score within 3 points of brunettes and those with red or black hair.

While jokes about blondes may seem harmless to some, it can have real-world implications, according to Jay Zagorsky, author of the study and a research scientist at The Ohio State University. Research shows that stereotypes often have an impact on hiring, promotions and other social experiences.

This study provides compelling evidence that there shouldn’t be any discrimination against blondes based on their intelligence.

The study found that the average IQ of blondes was actually slightly higher than those with other hair colors, but that finding isn’t statistically significant. The results for blond white men were similar – they also had IQs roughly equal to men with other hair colors.

The study was published last week in the journal Economics Bulletin.
