6 Scientifically-Proven Signs You’re More Intelligent Than Average
People are always looking for magic tricks to become smarter or even look smarter. From the outside it is hard to tell who has the highest intelligence. In fact, there are a few ways to tell for sure who is smarter. These ways are not just by looks or feeling but by actual research from scientists. Is it nature or nurture? Science says it can be a little bit of both. The following ways are research backed signs of intelligence.
1. Inheritance from Parents
The number one most likely indicator of above average intelligence is having smart parents. Children of doctors, engineers, scientists, lawyers, professors and other bright people tend to be smarter than the average person. For example, Albert Einstein’s children were all university professors and even his grandchildren became famous engineers. Low IQ prisoners tend to have children that also end up in prison (although this has a number of other factors besides intelligence). Unfortunately, this is something you can’t change unless you have the ability to go back in time.
2. People who don’t smoke
This is one that you can have a lot more control on. People that smoke (either cigarettes or marijuana to a lesser extent) actually lower their IQ over time. According to researchers who did a study of 20,000 individuals, people that smoke had an average IQ of around 90, whereas the general population has an average IQ of 100. Those 10 points make a huge difference in cognitive ability. While it is unclear if smoking causes the IQ drop or the people with low IQ tend to smoke, researchers have found a strong correlation.
