Researchers have identified new signs of intelligent people. These include:
1. Not smoking, as studies have shown that non-smokers tend to have higher IQs than smokers.
2. Being quiet and reserved, as intelligent people often think before speaking and prefer to listen rather than talk.
3. Finding connections between seemingly unrelated things, which is a sign of creativity and intelligence.
4. Holding liberal views, as research has shown that liberals tend to be more open-minded and intelligent.
5. Asking big questions and worrying about the future, which is a sign of a curious and intelligent mind.
6. Being faithful, especially for men, as research has shown that faithful men tend to be more intelligent than those who cheat.
7. Having surprising hobbies that inspire creativity and new ideas.
8. Taking risks and testing new ideas, which is a sign of intelligence and a willingness to learn.
9. Nail biting or other habits that are signs of perfectionism and a desire for control.
These signs are not definitive indicators of intelligence, but they may be traits that are more common among intelligent people.
