Intelligence quotient - Wikipedia, the free encyclopedia (4662 words) |
 | IQ tests are designed to be approximately normally distributed, which results in a "bell curve" graph of IQ score frequency. |
| Among the middle class of industrial societies, IQ is highly heritable, and by adulthood the influence of family environment on IQ is undetectable. |
| While IQ is sometimes treated as an end unto itself, scholarly work on IQ focuses to a large extent on IQ's validity, that is, the degree to which IQ predicts outcomes such as job performance, social pathologies, or academic achievement. |
