Learn about the history, methodology, and science behind our test
What is IQ?
IQ stands for Intelligence Quotient and is a standardized measure of a person's cognitive ability relative to the general population. The concept was developed in the early 20th century and has become one of the most widely used ways to assess intelligence.
An IQ of 100 represents the population average. Most people (about 68%) have an IQ between 85 and 115. An IQ above 130 is considered exceptionally high, and above 145 indicates giftedness.
