Why blondes arent dumb

However, while it may be true that intelligence isn't different, perception comes into play quite a bit with the blonde stereotype, notes study author Jay Zagorsky, a research scientist at The Ohio State University. While jokes are jokes and should be taken as such, Zagorsky says that "research shows that stereotypes often have an impact on hiring, promotions, and other social experiences.

So being a blonde means I'm smarter and more fun? I'll take both, sure. Just don't hold it against me, please. By Rachel Jacoby Zoldan March 22, Save FB Tweet More. Be the first to comment!

No comments yet. She explained how to debunk the claim that blondes are the smartest hair type one step at a time. First off: Zagorsky did not find any statistical difference between blondes and brunettes.

It's just not reported in his data. Just that fact alone debunks the assertion that blondes are the smartest hair type! Now on to redheads. There, he found a significant difference, but only by inflating the definition. Usually, the standard for significance is a value of.

But when he compares blond women and redheads, he reports a value between. Most scientists would say this is not significant. In his comparison of black-haired women to blondes, he does find a significant. But, this too can be debunked. He used what's known as a one-sided test, which statisticians frown upon. In this case, a one-sided test only allows him to test the idea that blonds are smarter. A two-sided test would be better: it would also account for the possibility black haired women are smarter.

If you were to conduct a two-sided test with this data, Nuzzo says, you'll find the significant difference goes away. And it becomes very plausible that black-haired women may actually be smarter.

Broadly, differences in IQ are linked to academic achievement — but not at such small scales. Differences between people who have IQs of 80 and may be meaningful an IQ of is considered average. But not differences between Those scores are practically identical, even if a statistical analysis claims to find a difference. I reached out to Zagorsky over email to clear some of this up. He said the point of the study wasn't to show that blondes are smarter, but to show that the dumb-blonde stereotype is a myth.

The average IQs were These differences are small and aren't statistically significant, but the fact that blonde women came out on top does shoot to hell the notion that they're at the bottom rung of the intelligence ladder. Of course, we didn't need a study to tell us that hair color has absolutely nothing to do with intelligence, but it's good to know that the scientific community is on board too.
