History of IQ

Among the general population, scores cluster around 100 and gradually decrease in either direction, in a pattern known as the normal distribution (or "bell") curve figure.

In modern times, the first scientist to test mental ability was Alfred Binet, a French psychologist who devised an intelligence test for children in 1905, based on the idea that intelligence could be expressed in terms of age. Binet created the concept of "mental age," according to which the test performance of a child of average intelligence would match his or her age, while a gifted child's performance would be on par with that of an older child, and a slow learner's abilities would be equal to those of a younger child. Binet's test was introduced to the United States in a modified form in 1916 by Lewis Terman. The scoring system of the new test, devised by German psychologist William Stern, consisted of dividing a child's mental age by his or her chronological age and multiplying the quotient by 100 to arrive at an "Intelligence Quotient" (which would equal 100 in a person of average ability).

The Intelligence Scales , also developed in 1949 by scientist, addressed an issue that enthusiasm the interest towards IQ tests , the fact that there are different types of intelligence. The scales develops the new dimensions of single mental-age score with a verbal scale and a performance scale for nonverbal skills to address each test taker's individual combination of strengths and weaknesses.

As already proved, the IQ scores are good predictors of academic achievement in elementary and secondary school, the correspondence between IQ and academic performance is less consistent at higher levels of education, and many have questioned the ability of IQ tests to predict success later in life. In the future, these IQ tests will definitely be able to measure many of the qualities necessary for achievement in the world of work, such as persistence, self-confidence, motivation, and interpersonal skills, or the ability to set priorities and to allocate one's time and effort efficiently

Recent theories that define intelligence in ways that transcend the boundaries of tests chiefly designed to measure abstract reasoning and verbal comprehension. As, Intelligence Quotient Test addresses not only internal thought processes but also how they operate in relation to past experience and to the external environment. Harvard University psychologist has posited a theory of multiple intelligences that

Includes seven different types of intelligence:
1-Linguistic - Sensitivity to the meaning and sounds of words.
2-Logical-Mathematical - Ability to operate on and to perceive relationship in abstract symbol systems.
3-Spatial - Ability to perceive visual.
4-Interpersonal - Ability to detect and respond appropriately to the moods of others.
5-Intrapersonal - Sensitivity to one’s own inner states.
6-Musical - Ability to combine musical tones and phrases.
7-Bodily-Kinesthetic - Ability to use the body skilfully.

Flying in the face of prevailing belief in the effects of environmental factors on intelligence, Jensen argued that the effectiveness of the government social programs of the 1960's War on Poverty had been limited because the children they had been intended to help had relatively low IQs, a situation that could not be remedied by government intervention. Jensen was widely censured for his views, and standardized testing underwent a period of criticism within the educational establishment, as the National Education Association called for a moratorium on testing and major school systems attempted to limit or even abandon publicly administered standardized tests. Another milestone in the public controversy over in the 1981, which critiqued IQ tests as well as the entire concept of measurable intelligence.

Many still claim that IQ tests are unfair to members of minority groups because they are based on the vocabulary, customs, and values of the mainstream, or dominant, culture. Some observers have cited cultural bias in testing to explain the fact that, on average, African-Americans and Hispanic-Americans score 12-15 points lower than European-Americans on IQ tests. (Asian-Americans, however, score an average of four to six points higher than European-Americans.) A new round of controversy was ignited with the 1994, who explore the relationship between IQ, race, and pervasive social problems such as unemployment, crime, and illegitimacy.

One more very important factual has arisen with the discovery that IQ scores in the world's developed countries—especially scores related to mazes and puzzles—have risen dramatically since the introduction of IQ tests early in the century. Scores in the United States have risen an average of 24 points since 1918, scores in Britain have climbed 27 points since 1942, and so on and comparable figures have been reported throughout Western Europe, as well in Canada, Japan, Israel, Australia, and other parts of the developed world.
