A high IQ society is an organization that limits its membership to people who have attained a specified score on an IQ test. The oldest and best-known such society is Mensa International,[1] which was founded by Roland Berrill and Lancelot Ware in 1946. Other societies are Intertel, founded by Ralph Haines in 1966; the Triple Nine Society, founded in 1978; the Prometheus Society; and the Mega Society.

Entry requirements[edit]

High IQ societies typically accept a variety of IQ tests for membership eligibility; these include WAIS, Stanford-Binet, and Raven's Advanced Progressive Matrices, amongst many others deemed to sufficiently measure or correlate with intelligence. Tests deemed to insufficiently correlate with intelligence (e.g. post-1994 SAT, in the case of Mensa and Intertel) are not accepted for admission.[2][3][4] As IQ significantly above 146 SD15 (approximately three-sigma) cannot be reliably measured with accuracy due to sub-test limitations and insufficient norming, IQ societies with cutoffs significantly higher than four-sigma should be considered dubious.[5][6][7]

Some societies[edit]

Some societies, including widely known societies such as Mensa, accept the results of standardized tests taken elsewhere. Those are listed below by selectivity percentile (assuming the now-standard definition of IQ as a standard score with a median of 100 and a standard deviation of 15 IQ points):

Name Established No. of members Approx. no. of countries Fees Eligibility Approx. IQ
Mensa International 1946 ~134,000[8] (as of May 2017) 100 Annual dues as of November 2017 for American Mensa are $79 (dues differ by country); life membership cost varies by age Top 2 percent of population (98th percentile; 1 person out of 50) 130
Intertel 1966 1,300–1,400 (as of January 2014) 31 Annual dues are $39 Top 1 percent (99th percentile; 1 out of 100) 135
Colloquy 1998 Unknown 24[9] $0 Top 0.5 percent (99.5th percentile; 1 out of 200) [10] 140
Triple Nine Society 1978 1,800+ (as of November 2017) 46 Annual dues are $10; life membership is $183 Top 0.1 percent (99.9th percentile; 1 out of 1,000) 146
Prometheus Society 1982 ~120 (as of January 2014) 13 Annual dues are $10 Top 0.003 percent (99.997th percentile; 1 out of 30,000; not reliably measurable with current tests) 160
Mega Society 1982 26 (as of January 2014) Unknown Annual dues are $39 Top 0.0001 percent (99.9999th percentile; 1 out of 1,000,000) 171.3
