Founded in 2011 by Dr Evangelos G. Katsioulis, GRIQ society is an international society for people having tested at a high IQ (Intelligence Quotient) at or above the second standard deviation above the statistical mean of the population (i.e. an IQ 130, sd 15 or an IQ 132, sd 16). The society sponsors international memberships.

The name GRIQ comes from the combination of the first two letters of the word Great and/or Grand and the IQ component. The number of letters before the IQ component of the society name (GR, 2) is directly related to the two standard deviations above the mean required on an IQ performance for anyone to claim membership in the society.
