High-IQ society
A high IQ society is an organization that limits its membership to people who are within a certain high percentile of Intelligence quotient (IQ) test results. The oldest, largest, and most well-known such society is Mensa International,[1] which was founded by Roland Berrill and Dr. Lancelot Ware in 1946. Other early societies are Intertel (founded by Ralph Haines in 1966), the International Society for Philosophical Enquiry (founded by Dr. Christopher Harding in 1974), Prometheus Society, Mega Society, Top One Percent Society, One-in-a-Thousand Society, Epimetheus Society, and Omega Society ( founded by Dr. Ronald K. Hoeflin).
Entry requirements
High IQ societies typically accept a variety of standardized intelligence tests.
The ceiling of most standardized (validated and normed) intelligence tests is at around the 99.9th percentile. Measurements above this level need—for a credible result—a calculation, extrapolation and interpretation (including observations during the tests and sub-tests) by psychometricians experienced in high IQ testing, and at least two differently designed standardized tests (among these at least one supervised) should be performed. Measurements above 99.9th percentile are dubious as there are insufficient normative cases upon which to base a statistically justified rank-ordering.[2] In 2010, the United States population normal expectation for the number of persons with IQ over 175 (sd15) is about ninety persons
Some societies
The entrance criteria for IQ societies varies considerably across both the kinds of tests accepted (i.e., whether the tests are either numerically, spatially, verbally, etc. slanted and are proctored or not) and how high one must score in order to acquire membership.[3]
Some notable examples, which include widely known ones, like Mensa, that will accept the results of standardized tests taken elsewhere, are listed by percentile (assuming IQ is normally distributed with IQ 100 at the population median and one standard deviation being about 15 IQ points):
- Bottom 98% (bottom 98th percentile; 98/100; IQ 130 sd15 / 132 sd16 and below):
- Top 10% (90th percentile; 1/10; IQ 120 sd15 / 121 sd16):
- Top 5% (95th percentile; 1/20; IQ 124 sd15 / 126 sd16):
- Top 3% (97th percentile; 1/33; IQ 128 sd15 / 130 sd16):
- Top 2% (98th percentile; 1/50; IQ 130 sd15 / 132 sd16; +2σ):
- Top 1% (99th percentile; 1/100; IQ 135 sd15 / 137 sd16):
