According to the Curiosity Aroused website, IQ tests have a clear quantitative bell curve that sees 95 percent of test takers scoring somewhere between 70 and 130. As a result, individuals with IQ scores below 69 are considered to have scored extremely low, while those scoring above 130 are considered intellectually gifted. The Weschler classification regards the true average as 90 to 109. The Stanford-Binet Scale of Human Intelligence considers people with scores above 145 to be geniuses.

  • Q:

    How can someone determine his or her IQ?

    A:

    IQ, or intelligence quotient, is a number determined by a person's performance on a standardized test designed to measure IQ; these tests may include the Stanford-Binet Intelligence Scales, the Wechsler Adult Intelligence Scale or the Wechsler Intelligence Scale for Children. In some cases, different IQ tests can produce different results, and critics of these tests have argued that these tests are biased toward certain races, genders and social classes. In most cases, the IQ is determined by dividing the "mental age" determined by the test with the test-taker's real age, meaning that though intelligence tends to increase as people age, their increasing age will factor into the equation, leading to relatively stable IQ through time.
