General Information

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 (IQ 130, sd 15 resp. IQ 132, sd 16).

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.

Founded in 2011 by Dr Evangelos G. Katsioulis, GRIQ Society sponsors international memberships. GRIQ belongs to the group of IQ societies, that Dr Katsioulis found (QIQ, GRIQ, CIVIQ, HELLIQ and OLYMPIQ Societies) and it is the 25th member society of the WIN (World Intelligence Network).

GRIQ stands as a well organized introduction of anyone into the high IQ world. The society accepts members with a performance at the well-known to the high IQ world level of the second standard deviation above the mean (Mensa level). The society members will interact with each other and with any other member of the WIN member societies either in the WIN boards or in the WIN Chat.
