A high IQ society is an organization that limits its membership to people who are within a certain high percentile of Intelligence quotient (IQ) test results. The oldest, largest, and most well-known such society is Mensa International,[1] which was founded by Roland Berrill and Dr. Lancelot Ware in 1946. Other early societies were Intertel (founded by Ralph Haines in 1966), the International Society for Philosophical Enquiry (founded by Dr. Christopher Harding in 1974) and Prometheus Society (founded by Dr. Ronald K. Hoeflin in 1982).
