IQ test was developed by Hans Eysenck in the forties of the 20th century. In the fifties, the IQ test became very popular in Europe, and its author became a celebrity. Intelligence was measured by everyone: in offices and in a friendly circle. Expression like: “He has a low IQ” became a euphemism of the characteristics: “He’s a fool.” Which, by the way, is completely untrue.

After all, intelligence is defined as a set of cognitive abilities of a person, which indicate its level of thinking and ability to solve complex problems. Therefore, the task of tests for intelligence is to reveal what kind of thinking is most developed in a person – figurative, logical, verbal, etc., and also to assess its memory, level of development, attention.


The first tests to measure intelligence were created by Hans Eysenck within the framework of the Nazi project to create a race of superhumans. In the development of the test, he relied on the idea that for each age there are norms of intellectual development. By the way, Eysenck’s relations with the fascist ideology were quite confusing. On the one hand, he publicly denied the fascist views and once got involved because of these accusations of a fight.

On the other hand, at one time he was in very close relations at the top of the Third Reich. Nevertheless, Eisenck’s pen has several articles dealing with racial, genetic or sexual superiority. For example, in 1971, he was thrown with eggs during a public lecture, in which Eysenck argued that the IQ of blacks was, on average, 15 points lower than that of whites because of the characteristics of the genocode.

A person uses only 10 percent of the brain.

Studies show that we are using almost the entire brain, but this does not always happen. The less a person realizes the capabilities of the brain, the faster, especially after 40 years, memory fading. And its loss is inevitable. Another thing is that it can be pushed aside or slowed down by training the brain. Developing like muscles, during training, the brain forms new neural connections.

The final figure you get when passing the IQ test is an indicator of your mind and abilities.

Eysenck’s test contains several sections (so-called subtests) – on abstract, verbal, figurative thinking, etc. The results of the subtests are summarized, and in the end an average value is given. Therefore, in a person who has an outstanding figurative thinking and, let’s say, a very unimportant logical result of the IQ test will be so-so.

The higher IQ, the smarter its owner.

There is a joke that, say, the high test scores of Eysenck testify not to the intellect of a person, but only about his ability to pass tests for the intelligence coefficient well. In every joke, only a joke. IQ scores are an indicator of a person’s ability to learn something new. This is the extent to which a person can observe and understand what is happening. But they have nothing to do with practical intelligence or creative abilities. Large-scale studies have shown that the so-called intelligence coefficient (IQ) is a very relative “measure” for the human mind. IQ rather talks about the speed of thinking processes (it is necessary to perform tests for 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-wits”, 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 publications of the IQ test, Eysenck wrote that for achievement of life success, high perseverance and high motivation must necessarily be attached to high intelligence. A person with high intelligence, but devoid of perseverance, runs the risk of spending his entire life in anticipation of “his own hour.” Persistent in knowledge, but not motivated by any goals, a person risks not to get off the couch.Sad, but the greatest chance of success is a combination of perseverance plus motivation, even if there is no pronounced intelligence.

If the 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 too detailed, falling in the values ​​”from 150 to 160″ or “from 160 to 170”, etc. However, clear results always give Eysenck’s tests posted on the Internet.

You can take the test online and find out your own IQ.

All tests placed on the Internet are simplified versions of the Eysenck questionnaire. And if such a test gave you the result “171” with the note “Congratulations, your genius is undeniable”, you must add: “against the background of a group of third-graders.” The professional IQ test is reviewed every few years by psychologists and varies with the amendment to the Flynn effect.

IQ is a constant value.

First, it is necessary to distinguish between real intelligence and IQ test scores. Real abilities can vary slightly depending on mood, well-being and even self-esteem. As for the tasks from the test, we must always remember: the situation in which the test is located is somewhat artificial. A person can misunderstand poorly formulated or poorly translated into Russian (there were also such cases) conditions of the assignment. He can lose interest in this lesson in the middle of the test or be inattentive. And vice versa: you can practice solving puzzles from Eysenck’s test so that they will bounce off their teeth. But this is by no means an indication that his intellect has increased unspeakably.

There is an organization in the world that is classified in a cleaner way than the Masonic lodge, to which people with IQ, exceeding 170, belong.

All of them are princes of this world: the leaders of large corporations, influential politicians, well-known public figures. However, if you are a janitor with an exceptionally high intelligence, this organization will notice you sooner or later, take under the wing, and then you will be provided with an outstanding career. This myth with a humanistic background to expose even a little awkwardly. Let those whom he likes continue to believe in him. In fact, there is a more democratic organization that unites people with high intelligence – Mensa International. To power over this sinful world has nothing to do; Mensa is engaged in educational activities. But you can join this international brotherhood in only one way: pass the notorious test for the intelligence factor and show remarkable results.

Over the past 50 years, the average IQ of the inhabitants of the Earth has grown by 12 points.

The name of the New Zealand sociologist James Flynn named the effect, due to which each succeeding generation becomes smarter than the previous one. At least, faster and better perform tasks that are part of the psychological tests. There are several theories trying to explain the essence of the Flynn effect, but none of them is generally accepted. James Flynn himself developed a mathematical model that describes the most diverse 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. Confirm this version and some experimental data. In particular, it was noted that mothers and foster children, brought up in the same family, show close results in testing, although they have different biological parents.
