A List of High IQ Societies

MENSA

Mensa International is a non-profit organization and the largest and most well-known high IQ society in the world. It was founded in 1946 by Roland Berrill, an Australian barrister, and Dr. Lancelot Ware, a British scientist and lawyer. The society's primary goals are to foster human intelligence, encourage research into the nature of intelligence, and provide a stimulating intellectual and social environment for its members.

To qualify for membership in Mensa, candidates must score within the top 2% of the population on a standardized intelligence test. This typically corresponds to an IQ of 130 or above, depending on the specific test used. Mensa accepts various tests for admission, including their own supervised Mensa tests, as well as scores from other reputable IQ tests.

Mensa has over 100,000 members across more than 100 countries. The organization is structured into national groups, each with its own governing body, publications, and events. Mensa International is the overarching umbrella organization that connects these national groups.

Mensa offers a range of activities and benefits for its members, including local, regional, and international gatherings, special interest groups (SIGs) focused on various topics, and a variety of publications such as the Mensa International Journal, national newsletters, and magazines. Mensa also promotes educational initiatives, supports gifted children programs, and provides scholarships for students.

While Mensa's primary focus is on fostering intellectual growth and social interaction among its members, it also aims to use its collective resources and knowledge to contribute to the betterment of society as a whole.
