Average IQ in the World

IQ measures a person's cognitive ability compared to the general population. It is calculated through standardized tests designed to assess human intelligence. The average IQ is set at 100 in most IQ tests, with scores above and below this number indicating higher and lower cognitive ability, respectively.

The process of measuring IQ involves a series of tests that assess various aspects of intelligence, including memory, problem-solving skills, mathematical ability, and linguistic skills. These tests are carefully designed and calibrated to ensure accuracy and fairness.

Our article sourced data from "The Intelligence of Nations" by Richard Lynn and David Becker, which provides a comprehensive dataset of national IQs.
