I have been a member of all six high-IQ societies listed in the Encyclopedia of Associations: Mensa, Intertel, the International Society for Philosophical Enquiry, the Triple Nine Society, the Prometheus Society, and the Mega Society — but I currently belong to only three of these: Mensa, Triple Nine, and Prometheus. I am the founder of Prometheus and of the Noetic Society (formerly called the Titan Society). I consider myself the founder of the Mega Society, although some argue that Chris Harding has at least equal claim to that status. I am also a co-founder of the Triple Nine Society. Thus, I have been at least partly responsible for the establishment of four of the seven currently active high-IQ societies.
