Who inventented IQ test?

Question

Seriously, who invented iq tests, because people seem to use this as a basis of your intelligence. Who invented it?

Answer 1

Depends on "which one" your talking about.

Standford and Binet invented their test.

Weschler invented his.

Get the idea? Different tests measure the I.Q. differently. A number that would register as Genius on Stanford & Binet wouldn't necessarily on the Weschler Scale.

Just do research on each one and find the one you like.

Answer 2

Alfred Binet invented the first actual IQ test in France in the early 1900's. Shortly thereafter, Psychologist Louis Terman invented the first acknowledged American IQ test, followed and improved upon by James Wechsler, who adapted individual IQ tests for children and adults.

Answer 3

In 1905, the French psychologist Alfred Binet published the first modern intelligence test, the Binet-Simon intelligence scale. His principal goal was to identify students who needed special help in coping with the school curriculum. Along with his collaborator Theodore Simon, Binet published revisions of his intelligence scale in 1908 and 1911, the last appearing just before his untimely death. In 1912, the abbreviation of "intelligence quotient" or I.Q., a translation of the German Intelligenz-Quotient, was coined by the German psychologist William Stern.

A further refinement of the Binet-Simon scale was published in 1916 by Lewis M. Terman, from Stanford University, who incorporated Stern's proposal that an individual's intelligence level be measured as an intelligence quotient (I.Q.). Terman's test, which he named the Stanford-Binet Intelligence Scale formed the basis for one of the modern intelligence tests still commonly used today.

In 1939 David Wechsler published the first intelligence test explicitly designed for an adult population, the Wechsler Adult Intelligence Scale, or WAIS. Since publication of the WAIS, Wechsler extended his scale downward to create the Wechsler Intelligence Scale for Children, or WISC, which is still in common usage. The Wechsler scales contained separate subscores for verbal and performance IQ, thus being less dependent on overall verbal ability than early versions of the Stanford-Binet scale, and was the first intelligence scale to base scores on a standardized normal distribution rather than an age-based quotient. Since the publication of the WAIS, almost all intelligence scales have adopted the normal distribution method of scoring. The use of the normal distribution scoring method makes the term "intelligence quotient" an inaccurate description of the intelligence measurement, but I.Q. still enjoys colloquial usage, and is used to describe all of the intelligence scales currently in use.



An intelligence quotient or IQ is a score derived from a set of standardized tests of intelligence. Intelligence tests come in many forms, and some tests use a single type of item or question. Most tests yield both an overall score and individual subtest scores. Regardless of design, all IQ tests attempt to measure the same general intelligence.[1] Component tests are generally designed and selected because they are found to be predictive of later intellectual development, such as educational achievement. IQ also correlates with job performance, socioeconomic advancement, and "social pathologies". Recent work has demonstrated links between IQ and health, longevity, and functional literacy.[2][3]

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. That is, significant variation in IQ between adults can be attributed to genetic variation, with the remaining variation attributable to environmental sources that are not shared within families. In the United States, marked variation in IQ occurs within families, with siblings differing on average by around 12 points.

The average IQ scores for many populations were rising during the 20th century: a phenomenon called the Flynn effect. It is not known whether these changes in scores reflect real changes in intellectual abilities. On average, IQ scores are stable over a person's lifetime, but some individuals undergo large changes. For example, scores can be affected by the presence of learning disabilities.

Answer 4

Prussian Blue... you don't need to know who invented the IQ test to succeed in your line of work.
Just remember, chin to chest annnnd SWALLOW.
Happy hoin'

Answer 5

hard to take it seriously but
the guy that came up with it was one who presumed to know all the answers ,,thus is it that ,any one as smart as him will answer the same
any one not knowing that he claimed to know then was clearly retarded ,the higher your numbers the more you have in common with the special privatised ,limited knowledge held by the elite to be wisdom that then becomes the mean
that predetermines to exclude the average.

Answer 6

I don't have the I.Q. to answer this question, but I'd like to know myself! Good luck!
