Prudentia High IQ Society was founded on July 12th, 2018. It is a high IQ society for people with an IQ of 140 or higher on a scale with standard deviation 15 (99.6th percentile). Basically that means that there is a website on which people who have an IQ of 140 SD 15 or higher are listed. In addition there is a journal which issues from time to time.

If you want to join Prudentia and be listed on this website, please provide your name, country of residence, hobbies/interests, a scan of your identity (e.g. passport) and a proof that you have a qualifying IQ (e.g. scan of IQ certificate). You can also include a link to your personal website if you have one. Membership is free of charge.
