Intelligence quotient - Race and IQ. Main article: Race and intelligence While the distributions of IQ scores among different racial-ethnic groups overlap considerably, groups differ in where their members cluster along the IQ scale. Some groups (e.g. East Asians and Jews) tend to cluster higher than whites, while other groups (e.g. blacks and Hispanics) tend to cluster lower than whites. Similar clustering occurs with related variables, such as school achievement, reaction time, and brain size. Man ...

An intelligence quotient or IQ is a score derived from a set of standardized tests developed to measure a person's cognitive abilities ("intelligence") in relation to their age group. An IQ test does not measure intelligence the way a ruler measures height (absolutely), but rather the way a race measures speed (relatively). For people living in the prevailing conditions of the developed world, IQ is highly heritable, and by adulthood the influence of family environment on IQ is undetectable. IQ test scores are correlated with measures of brain structure and function, as well as performance on ...

The role of genes and environment (nature vs. nurture) in determining IQ is reviewed in Plomin et al. (2001, 2003). The degree to which genetic variation contributes to observed variation in a trait is measured by a statistic called heritability. Heritability scores range from 0 to 1, and can be interpreted as the percentage of variation (e.g. in IQ) that is due to variation in genes. Twins studies and adoption studies are commonly used to determine the heritability of a trait. Until recently heritability was mostly studied in childre ...

Main article: General intelligence factor Modern IQ tests produce scores for different areas (e.g., language fluency, three-dimensional thinking, etc.), with the summary score calculated from subtest scores. Individual subtest scores tend to correlate with one another, even when seemingly disparate in content. Analyses of an individual's scores on the subtests of a single IQ test or the scores from a variety of different IQ tests (e.g., Stanford-Binet, WISC-R, Raven's Progressive Matrices and others) will reveal that they all m ...

Main article: Brain size and intelligence Modern studies using MRI imaging have shown that brain size correlates with IQ by a factor of roughly .35 to .40. In 1991, Willerman et al. used data from 40 White American university students and reported a correlation coefficient of .35. Other studies done on samples of Caucasians show similar results, with Andreasen et al (1993) determining a correlation of .38, while Raz et al (1993) obtained a figure of .43 and Wickett et al (1994) obtained a figure of .40.

Main article: Flynn effect Worldwide, IQ scores appear to be slowly rising, a trend known as the Flynn effect. However, tests are only renormalized occasionally to obtain mean scores of 100, for example WISC-R (1974), WISC-III (1991) and WISC-IV (2003). Hence it is difficult to compare IQ scores measured years apart. ...

IQ scores are expressed as a number normalized so that the average IQ in an age group is 100. In other words, an individual scoring 115 is above average when compared to people in the same age group. It is common practice to standardize so that the standard deviation (σ) of scores is 15. (The Stanford Binet IQ test uses a standard deviation of 16.) Tests are designed so that the distribution of IQ scores is Gaussian; that is, it follows a bell curve. A difference has been documented between the IQ score distributions of left-handed and right-handed test subjects; the distribution in left-hand ...

Intelligence quotient - Sex and IQ. Main article: Sex and intelligence Most IQ tests are designed so that the average IQs of males and females are equal. However, men tend to score their highest in the parts of the test that cover spatial and quantitative abilities, and women generally score their highest in the verbal sections. Some research has indicated that the variance in men's IQ scores is greater than the variance among women's, as seen in other cognitive test scores. This would mean that men are more likely than women to have both very high and very low IQs. < ...

While a large amount of one's IQ is predetermined by genetic factors, the environment can play a role as well. IQ can be improved to a certain extent through reading and application. Improvement in diet and regular exercise can help certain cognitive functions, and getting a little extra sleep can help as well. Depression and stress reduce IQ somewhat, so removal of these factors might also help. Drugs designed to improve cognitive fu ...

Some maintain that IQ is a social construct invented by the privileged classes, used to maintain their privilege. Others maintain that intelligence, measured by IQ or g, reflects a real ability, is a useful tool in performing life tasks and has a biological reality. The social-construct and real-ability interpretations for IQ differences can be distinguished because they make opposite predictions about what would happen if people were given equal opportunities. The social explanation predicts that equal treatment will eliminate ...

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. Different IQ tests differ in their validity for various outcomes. Tests also differ in their g-loading, which is the degree to which the test score reflects general mental ability rather than a specific skill or "group factor" such as verbal ability, spatial visualization, or mathematical reaso ...

Evidence for the practical validity of IQ comes from examining the correlation between IQ scores and life outcomes. Research shows that intelligence plays an important role in many valued life outcomes. In addition to academic success, intelligence correlates with job performance (see below), socioeconomic advancement (e.g., level of education, occupation, and income), and "social pathology" (e.g., adult criminality, poverty, unemployment, dependence on welfare, children outside of marriage). Recent work has demonstrated links between ...
