The Spirit of High IQ Society


1. Promoting the general welfare by solving important problems.

2. Providing highly intelligent people with a forum for their views and insights irrespective of social privilege or educational background.

3. Encouraging social interaction among people of high mental ability, who often experience alienation due to the difficulty of communicating productively with normal people.

4. Assisting in the study of human intelligence, its applications, and its potential enhancement.
