What Is a Normal IQ Range?
There have been multiple classifications or tests for IQ, but the common conclusion places the normal or average IQ at 90 to 110. Tests for IQ are sometimes subjective based on the testing criteria and application, but the science is constantly evolving as new information about intelligence is uncovered.
The first IQ test was developed by the Frenchman Alfred Binet in 1904. Since its inception, the IQ test has been subjected to radical scrutiny and controversy. As of 2014, IQ tests seek to evaluate cognitive skills that remove factors such as socioeconomic standards and racial bias.
Mensa International is an organization that focuses on those with high IQs, and their goal is “to identify and foster human intelligence for the benefit of humanity.”
