People with mental retardation in the U. Nevertheless, misunderstanding of the unique nature and implications of mental retardation remains widespread. When a person with mental retardation confronts the criminal justice system, they are uniquely unable to take advantage of legal safeguards and to protect their constitutional rights. Mental retardation is a lifelong condition of impaired or incomplete mental development. According to the most widely used definition of mental retardation, it is characterized by three criteria: significantly subaverage intellectual functioning; concurrent and related limitations in two or more adaptive skill areas; and manifestation before age eighteen. Subaverage intellectual functioning.

Despite decades of research, mental retardation remains an amorphous concept defined not in black and white but in ever-changing shades of gray. As recently as 40 years ago, the condition was defined primarily by IQ scores, with a cutoff of about Although an IQ of is normal--is often considered a rough standard of retardation, psychologists point to many people with such low test scores who are able to live independently, hold down jobs, marry and have families. That difficulty casts what appears to be a straightforward decision by the Supreme Court in a vastly muddier light. Experts predict that the number of such cases will increase dramatically as prisoners on death row try to stave off their fates. The measurement of intelligence has a long and convoluted history that has been complicated by claims of racial bias in testing, the use of such tests on people with poor English skills, and controversy over the significance of test scores. Even aside from cultural issues, measuring IQ is an inexact science. Even if a good test is used and the subject cooperates, there is still a significant chance that the actual IQ--as opposed to the measured IQ--is 10 points higher or lower. Those with the lowest IQs often get the short end of the stick. Studies have shown that the average IQ of prison inmates is about But the effects of low IQ can be offset by perseverance, dedication and other positive character traits.

IQ classification is the practice of categorizing human intelligence, as measured by intelligence quotient IQ tests, into categories such as "superior" or "average". In the current IQ scoring method, an IQ score of means that the test-taker's performance on the test is of average performance in the sample of test-takers of about the same age as was used to norm the test. An IQ score of means performance one standard deviation above the mean, while a score of 85 means performance one standard deviation below the mean, and so on. By the current "deviation IQ" definition of IQ test standard scores, about two-thirds of all test-takers obtain scores from 85 to , and about 5 percent of the population scores above i. When IQ testing was first created, Lewis Terman and other early developers of IQ tests noticed that most child IQ scores come out to approximately the same number regardless of testing procedure. Variability in scores can occur when the same individual takes the same test more than once.

Even before IQ tests were invented, there were attempts to classify people into intelligence categories by observing their behavior in daily life.

An intelligence quotient IQ is a total score derived from a set of standardised tests or subtests designed to assess human intelligence. Historically, IQ was a score obtained by dividing a person's mental age score, obtained by administering an intelligence test, by the person's chronological age, both expressed in terms of years and months. The resulting fraction quotient was multiplied by to obtain the IQ score. Scores from intelligence tests are estimates of intelligence. Unlike, for example, distance and mass, a concrete measure of intelligence cannot be achieved given the abstract nature of the concept of "intelligence". IQ scores are used for educational placement, assessment of intellectual disability , and evaluating job applicants. In research contexts, they have been studied as predictors of job performance [20] and income. Raw scores on IQ tests for many populations have been rising at an average rate that scales to three IQ points per decade since the early 20th century, a phenomenon called the Flynn effect. Investigation of different patterns of increases in subtest scores can also inform current research on human intelligence.

David Wechsler , developer of the Wechsler—Bellevue Scale of which was later developed into the Wechsler Adult Intelligence Scale popularized the use of "deviation IQs" as standard scores of IQ tests rather than the "quotient IQs" "mental age" divided by "chronological age" then used for the Stanford—Binet test. Handbook of Psychological Assessment Fifth ed. Dumont Willis. In Davis, Andrew ed. See, e. Autosomal dominant intellectual disability. Two state statutes say that an I. It is, in fact, quite easy to cheat on an IQ test--if you want to lower your score. Share Feedback.

An average child cannot get a score that high just because they ate a good breakfast and felt good that day. Measure content performance. Share Feedback. In most of these cases, there is no evidence that these well-known individuals ever took a standardized IQ test, let alone shared these results with the public.
