ou can go to school as much as you want, but there are just some things that make you smarter than average that you’re born with or are just part of your personality.

Inc. came out with this list today of 10 signs you could be smarter than the average person that have nothing to do with your IQ or if you finished college. Here are some of the highlights:

If you’re an only child or the oldest sibling.
Basically, getting your parents’ full attention early on in your life helped make you such an intelligent person. So only children and older siblings have an intelligent edge from early on, which has nothing to do with the parents’ IQs. For people who have siblings, the older child normally takes on the “teaching” role in the relationship. True story, even though my little brother thinks he’s smarter than me, I’ll never let him forget that I taught him how to read.

You’re a lefty.
Sorry righties, but science says lefties are naturally more creative and better at remembering things. According to research and studies by The University of Athens, left-handed people were better at quickly coming up with solutions and creative ideas when faced with mental challenges.

You stay up late.
Science says that people who stay up late normally make higher incomes and are just more intelligent than those who wake up early. Studies show that night owls are better at inductive reasoning and innovative thinking too. Staying up late is one way to set yourself up for success because you’re more likely to have a more comfortable life.

You can make people laugh.
A study done in the ’70s proved that comedians have higher IQs compared to other average people. Aside from being smarter, funny people are also better conversationalists and are more sexually attractive. That being said, it’s also been proven that how funny you are relates to how many sexual partners you’ve had.

You’re introverted.
There’s a lot of evidence out there that shows introverted people are more intelligent on average. For example, a study done by The Gifted Development Center showed that 60 percent of gifted children are introverts. Studies also show that introverts are more verbally intelligent than extroverts.

It’s not like if you’re an unfunny, right handed extroverted morning person that means you’re not smart. These are just some traits that could possibly indicate you’re smarter than average. You can read the full list here.
