If you feel like you see the world differently to your friends, this might be a sign of something positive.

Studies have shown that there are certain attributes that smart individuals possess which are not found in the average person.

So, if you are looking to find out whether your brain functions better than the standard human brain, you are in the right place!

In this article, we describe 9 signs that indicate you’re smarter than the average person:

1) You’re a firstborn

According to a study that surveyed 250,000 Norwegians, the oldest sibling in a family has an average IQ that is 2.3 points higher than their younger siblings. This is not because of genetics (which can differ from family to family), but instead due to family dynamics and environment.

Generally, the firstborn in a family receives full parental attention and when the younger sibling arrives, the firstborn is responsible for tutoring them. This boosts intelligence, grooms personality, and enhances cognitive abilities in the firstborn.

2) You lack of common sense

Contrary to popular belief, people that are intelligent actually lack ‘common sense’. According to evolutionary psychologist Satoshi Kanazawa, this is because their intelligence overrides it:

“They think in situations where they are supposed to feel…In evolutionary familiar domains such as interpersonal relationships, feeling usually leads to correct solutions whereas thinking does not.”

In other words, letting your emotions guide you from time to time is actually a good thing.

3) You’re left-handed

A report from the New Yorker suggests that people who are left-handed have more accurate and quicker spatial skills, amplified working memory, and enhanced mental flexibility than right-handers.

The study also states that ‘lefties’ are divergent thinkers that have a specific creative ability which allows them to generate brilliant ideas without putting much thought to it.

4) You’re a musician

Evidence suggests that individuals that can play at least one musical instrument have functionally and structurally different brains when compared with non-musicians.

There is a separate region of the brain that processes music and it plays a key role in enhancing our language and memory skill.

According to this research, the parts of the brain that are used for processing music are more active in musicians and when you start to learn an instrument, it can actually change the overall neurophysiology of your brain.

5) You’re a night owl

People that go late to bed at night generally have a higher IQ than those that are early risers (people who prefer waking up early), according to research.

Night owls also lead more comfortable lives and tend to earn more in their occupations, as well.

6) You were a breastfed baby

According to a study of 6,000 people in Brazil, people that have been breastfed in infancy tend to earn more income and achieve more success.

Generally, babies that are nursed and breastfed by their mothers score much higher on intelligence tests as adults than those who have not been nursed.

7) You did drugs

According to Psychology Today, individuals that have higher intelligence have a higher probability of consuming all kinds of psychoactive drugs when compared to their less intelligent counterparts.

The same study also concludes that women who have a higher IQ are at a greater risk of using drugs such as magic mushrooms, cocaine, cannabis, and amphetamines.

8) You’re curious

The curiosity quotient (CQ) is defined as how powerfully motivated individuals are to learn about something of interest. The Harvard Business Review reports that people with a higher CQ generate original ideas more frequently and their thinking style allows them to acquire more knowledge than people who have a lower CQ.

These individuals are more inquisitive and their curiosity inspires them to understand the subject matter in a more detailed manner. Perhaps this is why one of the greatest scientists of all time, Albert Einstein, said “I have no special talents. I am only passionately curious.”

9) You have a sick humor

As sad as it might seem but if you laugh at the misfortune of others and sick jokes, then chances are that you are highly intelligent. The BPS Digest states that, in a study, the group which has the highest sick-humor appreciation rate scored the highest in nonverbal and verbal IQ tests and had received better education.
