Often Swearing
This might sound weird, but people who use more curse words and swears are more intelligent. It’s most likely that intelligent people have mastered their vocabulary and use a wider range of words to express their emotions in the most accurate way. Until recently, it was believed that those who swear are less educated people. However, a study done by psychologists found just the opposite: the more educated a person is, the more they swear.
Blondes Have More Fun
We’ve all heard the old stereotype that blondes are less intelligent. Not to mention, all the jokes. Well, a study of nearly 10,000 Americans found that blonds have slightly higher IQs than darker-haired people. However, it turns out that the difference was too small to be statistically significant. All the same, one thing can be said with certainty: blondes are not the least bit dumber than darker-haired people.
