The name "Mensa," which means "table" in Latin, reflects its nature as a round-table society, where factors such as race, color, creed, nationality, age, political views, and social or educational background are of no significance.

Mensa is a global, non-profit organization where the only requirement for membership is achieving a score at or above the 98th percentile on a recognized IQ test. It invites individuals from all backgrounds who have an IQ in the top 2% of the population, with the aim of fostering social interaction and engaging in various cultural and social activities.
