High IQ Societies from 2 sigma to 5 sigma, in which “sigma” applies to “S.D.” or standard deviation. For example, Mensa = 2 sigma, when S.D. equals 15, 16, or 24 , means 3 times 15, 16, or 24, or 130, 132, and 148, respectively. This list is for the admission of the USIA: United Sigma Intelligence Association.
