Mensa was founded in 1946 at Oxford University in England by two remarkable individuals: Roland Berrill, an Australian barrister, and Dr. Lancelot Ware, a British scientist and lawyer. The two met by chance on a train journey and discovered they shared a common interest in intelligence testing. They decided to form a society for people with high IQs, and the result was Mensa.
The name "Mensa" comes from the Latin word for "table," symbolizing the organization's goal of creating a round-table society where members meet as equals regardless of background, occupation, race, or any other characteristic. The only qualification for membership is intelligence.
Mensa grew slowly at first but steadily gained recognition. By the 1960s, the organization had established chapters in several countries, including the United States. Today, Mensa has grown to over 150,000 members across more than 100 countries, making it the largest and oldest high-IQ society in the world.
American Mensa, the U.S. chapter, now boasts over 50,000 members, representing one of the largest national groups within Mensa International.
Mensa has three stated purposes:
Boston has a rich intellectual history and is home to a vibrant Mensa community. The city's world-class universities, research institutions, and high concentration of knowledge workers make it a natural hub for high-IQ individuals. Mensa has active events and gatherings in the Boston area, including lecture series, game nights, and social events.
To qualify for Mensa, you must score at or above the 98th percentile on an approved standardized intelligence test. This means performing better than 98 out of every 100 people who take the same test.
Note that different tests use different standard deviations, which is why the qualifying scores vary. The consistent requirement is the 98th percentile.
Boston is home to a thriving Mensa community, reflecting the city's highly educated population and world-class academic institutions.
According to recent data, Massachusetts has approximately 2,500+ Mensa members, with many located in the Boston metropolitan area.
