The IQ test was developed by Hans Eysenck in the 1940s. In the fifties, the IQ test became wildly popular in Europe, and its author became a celebrity. Intellect was measured by everyone: both in offices and in a friendly circle. An expression like, "He has a low IQ" has become a euphemism for the characteristic: "He's a fool." Which, by the way, is not at all true.
After all, intelligence is defined as the totality of a person's cognitive abilities, which testify to his level of thinking and ability to solve complex problems. Therefore, the task of intelligence tests is to identify which type of thinking is most developed in a person - figurative, logical, verbal, etc., and also to assess his memory, level of development, attention.
The first tests to measure intelligence were created by Hans Eysenck as part of a Nazi project to create a race of supermen. In developing the test, he relied on the idea that each age has its own norms of intellectual development. By the way, Eysenck's relationship with the fascist ideology was rather complicated. On the one hand, he publicly denied fascist views and once got involved in a fight because of these accusations.
On the other hand, at one time he was in a very close relationship at the top of the Third Reich. Nevertheless, Eysenck penned several articles that talk about racial, genetic or sexual superiority. For example, in 1971, he was pelted with eggs during a public lecture at which Eysenck argued that the IQ of blacks is, on average, 15 points lower than that of whites due to the peculiarities of the gene code.
A person uses only 10 percent of the brain. Studies show that we use almost the entire brain, but this is not always the case. The less a person implements the capabilities of the brain, the faster, especially after 40 years, memory fading occurs. Moreover, its loss is inevitable. Another thing is that it can be pushed back or slowed down by training the brain. While developing like muscles, during training, the brain forms new neural connections.
The final number you get on the IQ test is an indicator of your intelligence and ability. Eysenck's test contains several sections (so-called subtests) - for abstract, verbal, figurative thinking, etc. The subtest results are summed up, and as a result, an average value is given. Consequently, a person who has outstanding imaginative thinking and, for example, a very unimportant logical final result of the IQ test will be so-so.
The higher the IQ, the smarter its owner. There is a joke that, they say, high scores of Eysenck's test do not indicate a person's intelligence, but only his ability to pass IQ tests well. In every joke there is only a fraction of a joke. After all, IQ scores are an indicator of a person's ability to learn something new. This is the degree to which a person can observe and understand what is happening. But they have nothing to do with practical intelligence or creativity. Large-scale studies have shown that the so-called intelligence quotient (IQ) is a very relative "measure" for the human mind. IQ rather speaks about the speed of thought processes (test tasks must be completed in a limited period of time), and not about the ability to think or about the originality of thinking. At the same time, among the greatest thinkers there were many "slow-witted", for example, Albert Einstein.
A person with a high IQ is more likely than others to succeed in life. In the preface to one of the popular editions of the IQ test, Eysenck wrote that in order to achieve success in life, perseverance and high motivation must be applied to high IQ. A person with high intelligence, but devoid of perseverance, runs the risk of spending his whole life waiting for "his hour". Persistent in knowledge, but unmotivated by any goals, a person runs the risk of not getting off the couch. Sadly, the best chance of success is a combination of persistence plus motivation, even in the absence of pronounced intelligence.
If a person's IQ is above 170, he is a genius. In professional IQ tests, the highest score is 144. The result that exceeds this number is not very detailed, falling into the values "from 150 to 160" or "from 160 to 170", etc. However, clear results are always given by Eysenck's tests posted on the Internet.
You can take a test online and find out your own IQ. All tests posted on the Internet are simplified versions of Eysenck's questionnaire. And if such a test gave you the result "171" marked "Congratulations, your genius is undeniable", you must add: "against the background of a group of third-graders." The professional IQ test is reviewed by psychologists every few years and is adjusted for the Flynn effect.
IQ is a constant value. First, it is necessary to distinguish between real intelligence and IQ test scores. Actual abilities can vary slightly depending on mood, well-being, and even self-esteem. As for the problems from the test, you always need to remember: the situation in which the tester finds himself is somewhat artificial. A person may misunderstand poorly formulated or poorly translated into Russian (there have been such cases) conditions of the assignment. He may lose interest in the activity or be inattentive in the middle of the test. And vice versa: you can practice solving Eysenck's test problems so that they bounce off your teeth. But this by no means will be an indicator that his intelligence has increased unspeakably.
There is a certain organization in the world, which is more classified than a Masonic lodge, to which people with IQs exceeding 170 belong. All of them are the princes of this world: leaders of large corporations, influential politicians, well-known public figures. However, if you are a janitor with exceptionally high intelligence, this organization will sooner or later notice you, take you under its wing, and then an outstanding career is guaranteed for you. It's even a little embarrassing to expose this myth with a humanistic background. Let those who like him continue to believe in him. In fact, there is a more democratic organization that unites people with high intelligence - Mensa International. It has nothing to do with power over this sinful world; Mensa is more involved in educational activities. But there is only one way to join this international brotherhood: to pass the notorious IQ test and show remarkable results.
Over the past 50 years, the average IQ of the inhabitants of the Earth has grown by 12 points. New Zealand sociologist James Flynn is named after the effect due to which each subsequent generation becomes smarter than the previous one. At least, he performs faster and better on tasks included in psychological tests. There are several theories trying to explain the Flynn effect, but none of them is generally accepted. James Flynn himself developed a mathematical model that describes a wide variety of factors affecting mental development, and showed the connections between these factors. Flynn came to the conclusion that the level of intelligence is more dependent not on genes, but on the environment. This version is confirmed by some experimental data. In particular, it was noticed that native and adopted children brought up in the same family show similar results when tested, although they have different biological parents.
