Welcome to the International Society for Philosophical Enquiry


We are a Global organization, often known by its abbreviation, ISPE. We were incorporated as a non-profit in 1974 as The Thousand.® The Thousand is a registered trademark of ISPE.

ISPE is the oldest 99.9% Society in the world. It is the third oldest high IQ society in the world after Mensa (98%) and Intertel (99%). The only criterion for admission is a score on any standard psychometric test of intelligence reflecting ability at the 99.9th percentile. The results of many Educational Testing Service tests are also accepted by ISPE. See the "JOIN" tab for acceptable scores on all of the tests we accept. We also have our own un-timed take at home self-test that has been created and normed by our psychometrician.

We are a global organization with our members in fellowship, helping one another, and helping humankind, climbing the steps of achievement, finding solutions, and putting our creative brain power to work for humanity in many ways.  Please take this opportunity to get to know us better. You will find that we are unique among other IQ societies in several beneficial ways. These have always been a part of our Charter.

Those who join us often find a renewed life and a new sense of purpose in addition to lasting friendships with others striving to help humankind.

There are immediate benefits as well.  The fellowship and real time interaction provided by our unique private social network is a highlight. (See the "Join" tab for more information).

We have zero tolerance for ad hominem attacks on any of our social media platforms.
You are free to espouse any opinion on any of our social media platforms as long as you are respectful of others that may have opposing points of view. Naturally, we have no tolerance for views that advance or encourage any criminal activity or thought, any racist, misogynist, xenophobic or other intolerant behaviors. If you post anything that violates any criminal laws, we will identify you to the proper legal authorities and cooperate fully with their requests to assist them. All of our official social media sites are closed to the public. You can be assured that you are communicating with other ISPE members only.

ISPE membership is completely inclusive. It officially espouses no causes and no political agenda. It is a democratic organization. It welcomes all regardless of race, creed religion, sexuality or gender identity.  It is operated solely by volunteers. Members give their time to support our organization. They give their time to benefit humanity individually and through our special interest projects and programs. 

In addition to our noted journal Telicom, we operate several social media sites and issue a newsletter.  We will shortly issue free membership identity email addresses to all active members.

We welcome you to this website and we encourage you to either take our properly normed self-test for admission designed by our psychometrician or submit your own score report from any well-recognized third-party psychometric test of intelligence.

Please see the "About" tab to find more information about our organization.  

ISPE is a  nonprofit organization under U.S. I.R.C. 501(c)(3).
