If you are the type of person who doesn’t go to bed until the wee hours of the night, whose house is not Martha Stewart clean, and have been told on more than one occasion you swear like a sailor… you’re probably highly intelligent.  And that’s science talking!

While intelligent people are expected to be organized and have high self-control compared to those with an average IQ, it turns out that may not be the case for some.

Go ahead, revel in your messiness, drop a few eff-bombs, and don’t stress about your messy house because according to scientists, this means you actually have a sharp mind and high levels of intelligence.

Here’s why:

Intelligent people tend to be messy.

No matter what you’re doing or where you are, you always leave a mess behind. But, guess what? There’s good news for you.

A study by the psychological scientist Kathleen Vohs at the University of Minnesota suggests that a messy desk and disorderly environment are signs of a higher IQ.

And really, if you think about it more carefully, you’ll see that when your mind is engaged in important things, organizing and cleaning stuff around you is the least of your worries.

Moreover, the study also shows that messy environments encourage creativity. In reference to this, Vohs says “Disorderly environments seem to inspire breaking free of tradition, which can produce fresh insights.”

So, if you’re messy, don’t be embarrassed. Having this habit doesn’t only prove that you’re intelligent, but it also helps you to break free of convention, think in creative ways, and produce new ideas.

Intelligent people stay up late.

If you tend to stay up late, don’t worry because the only negative thing about this is that you’re probably very tired in the mornings. One scientific study shows that more intelligent people are more likely to be nocturnal than less intelligent people.

The thing is that the circadian rhythm, or your natural body clock, works in a different way in you than in others. In reference to this, this is what the study revealed:” More intelligent children are more likely to grow up to be nocturnal adults who go to bed late and wake up late on both weekdays and weekends.”
