Think you’ve got what it takes to join the intellectual elite? Here is a list of nine high-IQ societies, with qualifying scores given from the Stanford-Binet IQ Test. The current version is SB-5, based on a sample of 4,800 individuals that matches the 2000 U.S. Census. Many of these societies will accept alternative intelligence tests such as SAT, LSAT, and GRE, or a qualifiying score on their own tests.
The society descriptions are taken from the respective websites, and I have included a sample of famous people that would qualify for each society based on this site.
The societies are listed in reverse order of exclusivity and all links are set to open in a new window.

The Member Lounge is our online community where members can enjoy stimulating discussions on a variety of intellectual and political topics far away from the stifling protocols of academia and the crude behavior found on so many Internet discussion groups.
The Member Lounge also has weekly online trivia contests in our trivia chat room, organized tournaments in chess, backgammon, and poker, debate competitions, fantasy sports, a stock market challenge, weekly polls and surveys, and a large collection of puzzles and brainteasers.

Colloquy is, to the best of our knowledge, the first high-IQ society based entirely on the Internet. It is created as a forum for the collegial sharing of thoughts, experiences, and creative expression among people of superior intelligence. Defining our terms, what could be considered as superior intelligence? Statistically, perhaps arbitrarily, the highest half-percent of the general populace are placed into this category, at 2.58 standard deviations above the mean. Assuming a 15.5 s.d., this level is 140 IQ… not that undue emphasis should be placed upon such tests. Intelligence is a curious quality, easily recognized while somewhat elusive when precise definitions are sought. Consider the contemporary theories of Gardner and Sternberg, which recognize multiple aspects of intelligence.
Famous personalities that would qualify: Hillary Clinton (140), Richard Nixon (143)
IQ 144+ (1 in 333)
No fee to join.
Cerebrals Society is an international non-profit organization dedicated to the search of high intellectual giftedness among individuals, bringing highly gifted individuals together, and making full use of high intellectual giftedness for the good of human society in general, where possible. Cerebrals society will strive to reach understanding and promote thoughtfulness within as without, to spread what it gathers and reach always one step further into uncertainties of humanity. In this, we may fail from time to time, but final successes are always traced by the failures that preceeded. Cerebrals was founded in December 1999 by Xavier Jouve. Over time the society has evolved into a growing organization which keeps providing its members with intellectual peerage and a chance to meet across distances thus reducing the sense of isolation (not at all physical) often present in varying degrees in persons with an high-IQ. Cerebrals Society is featured on the Beautiful Mind web site in the Genius Resources section.
Famous personalities that would qualify: Napoleon Bonaparte (145)
IQ 146+ (1 in 1000)
Membership fees: $10 USD or $30 USD annually depending on whether you want a virtual or hard copy of the group’s magazine.
The Triple Nine Society is committed to friendship, communication, the adventure of intellectual exploration, and a greater realization of individual potentials. It neither sanctions the imposition of one person’s philosophy on another nor subscribes to any particular philosophy for its members. It will strive to avoid the insularity of mere exclusiveness. The guiding principle of the Society is democratic and collegial rather than hierarchical. The Society will remain open to innovation and evolution.
Famous personalities that would qualify: Jayne Mansfield (149), Jean-Jacques Rousseau (150), Miguel de Cervantes (155)
IQ 156+ (1 in 11,000)
No fee to join.
Vertex Society is one of the very few HIQ societies whose members are selected by means of professional, standardized, supervised intelligence tests only, which makes the society entrance claim undoubted as per standards of the scientific community.
Vertex Society also fills an enormous gap. Up until the foundation of Vertex, there have been no HIQ societies that put their entry requirement between 3 and 4 standard deviations.
Societies, many of which ambiguous with regard to the validity of their admission tools, often clutter at the same cut-off points, providing no gradation, yet bringing confusion.
As Vertex Society is aimed at the opposite, it was deemed useless unless being strongly based on the use of professional tests only and providing finer gradation to the properly qualified members of the HIQ community. It is on these two principles that Vertex Society has been founded on and to which it is pledged to adhere.
Famous personalities that would qualify: No data, possibly because of the unusual range for admission. See the second paragraph in the society description.
IQ 160+ (1 in 30,000)
Membership fees: $10 USD or $25 USD annually depending on whether you want a virtual or hard copy of the group’s magazine.
The Prometheus Society was established in 1982 by philosopher Ronald K. Hoeflin, Ph.D. to promote fellowship among individuals with extremely high intelligence. Membership in the society is open to anyone who has received a score on an accepted IQ test that is equal to or greater than that received by the highest one thirty-thousandth of the general population. The Prometheus Society is a world-wide nonprofit organization with fewer than one hundred members. Currently there are participants from 18 countries.
The association with the mythological hero who stole fire and gave it to man as a gift is natural. The fire has from antiquity been symbolically associated with mental gifts which distinguish man from other beasts, all of his other capabilities being inferior to those of one or another animal. Explicitly acknowledged goals of the organization have always been to provide a forum for compatible discussions of topics and concerns unique to individuals with extremely high intelligence.
Famous personalities that would qualify: Bill Gates (160), Reggie Jackson (160), Stephen Hawking (160), Albert Einstein (160), Plato (170), Galileo (185), Isaac Newton (190), John Stuart Mill (200).
IQ 210+ (1 in 1,000,000)
No fee to join.
The Omega Society is an IQ society at the 99.9999th percentile (one-in-a-million level on a test of general intelligence) and exists for the recognition and encouragement of individuals of extremely high intelligence. It was founded by Ronald K. Hoeflin, Ph.D.
Famous personalities that would qualify: Leonardo Da Vinci (220), Marilyn Vos Savant (228)
