As an experimental high-range IQ project, GIGA Society is an extremely high-IQ society for those who score at or above IQ 190 (SD 15) on an acceptable high-range IQ test.

The official GIGA Society, which was established in 2001, is distinct from other giga-level societies in that it accepts scores from a variety of high-range IQ tests which have been developed by test authors from around the world. There are other giga-level societies which accept mainly tests authored by their society’s own founder. This is an extremely biased policy. To combat this questionable practice, the official GIGA Society accepts the world’s best high-range tests for admission consideration.

The official GIGA Society has a total of ten members worldwide, including individuals from Asia, Europe, and America. Their diverse professional backgrounds include MIT graduates and university professors. GIGA Society welcomes geniuses from all over the world.

The President of GIGA Society is Dr. Tom Chittenden who is an Honorary Professor in the Department of Artificial Intelligence at the University of London, UK.
