Mensa Bulgaria is a non-governmental organization of people with high IQ, created in 1991 with headquarters in Sofia. Mensa Bulgaria is a full member of the International Mensa, the high IQ society, founded in England in 1946 by Roland Berrill, a barrister, and Dr. Lance Ware, a scientist and lawyer. They had the idea of forming a society for bright people, the only qualification for membership of which was a high IQ. The original aims were, as they are today, to create a society that is non-political and free from all racial or religious distinctions. The society welcomes people from every walk of life whose IQ is in the top 2% of the population, with the objective of enjoying each other's company and participating in a wide range of social and cultural activities. Mensa has three stated purposes: to identify and foster human intelligence for the benefit of humanity, to encourage research in the nature, characteristics and uses of intelligence, and to promote stimulating intellectual and social opportunities for its members. Membership of Mensa is open to persons who have attained a score within the upper two percent of the general population on an approved intelligence test that has been properly administered and supervised.
