I'm gonna have to disagree with that.

Though it is true that people with a higher degree of intelligence are surely less social and are often misunderstood, I wouldn't recommend that they stop communicating with other people.

Rather, they should try to spread their knowledge to people by approaching them. People are always willing to learn something new, you just gotta find a way to teach them.

If the people with a higher IQ can find that way, they'll notice how people are more than willing to listen to them and discuss ideas.
