Un- Measurable: Why intelligence tests such as IQ scores should be treated with caution.
The dictionary defines a Latin derived word intelligence (Note: "inter" means "between", "casual" for "select read ',' intel casual" to "understand" for) a particular mental ability and prudence. However, what was meant by the term and will remain vague, since, neither could the various scientific Disciplines in recent years to agree on a common definition, nor are the researchers one that can be made by intelligence tests actually measure.

It was the Frenchman Alfred Binet, who is considered the founder of psychometrics, the theory and methodology of psychological measurement, developed in 1905 jointly with the physician Theodore Simon, a method to the mental capacity of children measured. Commissioned by the French Ministry of Education to identify special education students, they created tasks that had to be accomplished at a certain age. Divided by age group, was, inter alia, the ability to distinguish left from right or make a meaningful set of words was checked. The result was the so-called "intelligence age." The more tasks a child from a higher age group managed, the higher the "intelligence age" and vice versa. The German psychologist William Stern was 1912, the "intelligence age" in relation to age and thus created the term "intelligence quotient."
Since the abbreviation "IQ" for some scientists now exercised equally indiscriminate in the use of language is such as "BMI" (body mass index) for physical condition, some test procedures now take other values-lines approach. More than a hundred years after Binet there - similar to the definition of intelligence - while also no standard intelligence test in order to elicit the quotient. They range from the "analytical intelligence test" over the "Cattell Culture Fair III" to the "performance review system" and many more.
As different methods, they have in common besides the division by age one: you are assessed using various tasks in the form of numbers, letters or rows of figures, the spatial, mathematical, linguistic and logical thinking skills and imagination. On the test bench here are characteristics such as concentration and processing capacity. That is, the ability to solve complex tasks. Just as there is no uniform method for calculating the IQ, the scales are not standardized.
American scales, for example, beyond an IQ of 200 and are not comparable with Europe. Not only for this reason, often also incorrectly bandied IQs should be treated with caution. Still, despite differences of standard it has become to the average of the population of a 100 IQ to go out with a fluctuation band of plus-minus 15th An IQ of 70 or below is classed as mental retardation, an IQ of at least 130 as giftedness. Only an estimated 2.2 percent the population have such an IQ

Those who show their talent via test can become a member of Mensa. The middle of the last century, founded in the United Kingdom Association of Mensa International, currently has 110,000 members from a hundred countries worldwide. In Germany there are about 9000, according to association members, are in Austria, 570th Who extends far beyond the average - IQ 160 - can join the "Prometheus Society, which comprises about one hundred members.
Whether intelligence is but also what measures of intelligence test, "as written on the" Mensa "homepage is is up to them. Online there are numerous sites that offer free trials and are under an hour to complete. And there are deals to measure in 90 minutes or more to provide one hundred euro a chance in the undefined numbers.
