Get to know IHIQS

What is IHIQS?

IHIQS was started by Nathan Haselbauer as the New York High IQ Society in 2000, with the aim of promoting discussions on a variety of intellectual topics. The organization became IHIQS later that year to reflect its growing international membership and is open to individuals who have demonstrated an IQ in the top five percent of the population.

Our members are adult people from all walks of life and have very different backgrounds and personalities. We are proud to have many different cultures under one roof!.

What does IHIQS offer?

When you join IHIQS, you get a membership certificate and you can become a part of our online community to participate in forum discussions, learn from top experts, connect with intelligent people and advance yourself.

We have a private online Member Community and are available on Facebook as well as LinkedIn and Instagram. We also have offline events in some major cities. You will find yourself in an open-minded, collaborative environment.


Joining IHIQS

Why should I join?

We represent a contemporary movement and stimulate discussions on a variety of intellectual topics. We offer a platform to present ideas, discuss them in a friendly environment, share professional knowledge and enjoy learning! If you like that, or just want to be a registered member, you should join.

You will receive an official Membership Certificate soon after joining IHIQS. We are looking forward to meeting you soon!

What are the requirements?

You can join us if you are at least 15 years old and have an IQ score in the top five percent on any of our accepted tests, preferably our official admissions IQ test. Scores are not always distributed in the same way following different tests, but for a standard deviation of 15, this should be at least a 124 IQ. English is the primary language within IHIQS. We also have Dutch, German, Italian and Japanese groups.

How do I take the admissions test?

Prospective members can take our certified online admissions Culture Fair Intelligence Test (USD 8.99 / EURO 9,50) hosted at sites of 123test. You can take the free short demo IQ test first if you like (auch auf Deutsch: IQ-test).

After taking the admissions test you can download an IQ certificate which you can upload during your membership request as proof of a sufficiently high IQ score.

We do not accept any unproctored online test that is not officially recognized or certified by IHIQS. This includes the short (8 questions) demo version of the admissions test.

What are the other qualifying tests?

Other qualifying tests require a score in the top five percent. These tests have to be administered by a certified professional such as a psychologist or by a recognized educational institution. Online (sample) versions of these or any other tests are not accepted.
