7 Signs You Have Above Average Intelligence
4. You're a leftie.
Some research has indicated that people who are left-side dominant have what's called divergent thinking, which is a form of creativity which gives you novel and unusual problem solving skills.
5. You're slender.
A 2006 French study found that people who were more slender, indicating better health, had healthier minds as well. They performed better on vocabulary tests than their more overweight counterparts.
6. You aren't a smoker.
Smoking isn't smart, and it turns out, if you smoke, you likely have an IQ just a few points lower than the average non-smoker. That is, at least according to a 2010 study of 20,000 young men in Israel.
7. You played an instrument.
This one especially applies to people who played music as children. A 2011 study of verbal intelligence of 4-6 year-old children found increases in verbal proficiency after a month of playing an instrument.
