For years, there’s been a great debate about which gender is smarter.

Well, according to a new study, men aren’t necessarily smarter than women, but they sure think they are.

Researchers at Washington State University had men and women take a math test, then asked them how they thought they did.

And men were FAR more likely to overestimate their grades — women were actually very realistic in their predictions.

The researchers say it could be one of the reasons why more men go into math and science. They have the confidence and ego that makes them think they can take it on.
