How do people with normal and low IQs think? What is the IQ of a normal person

It has been statistically proven that IQ changes with age. It reaches its peak at the age of 25. It is generally accepted in the world that an IQ of 100 points is average. The IQ of a five-year-old reaches 50-75 points, at 10 years old it ranges from 70 to 80 points, at 15-20 years old it can reach the average value for an adult of 100 points. In many countries of the world (for example, the USA and Japan), gifted people are selected on the basis of IQ tests, and then they are trained according to an enhanced and accelerated system. This is due to the fact that children with an IQ increased for their age, as a rule, learn much better and faster than their peers.

Learn to analyze. It may not be skillful and at times stupid, but only in this way will your brain learn to analyze. For example, imagine two completely different things: a cat and a brick. Funny, but! Try to find as much in common between them as possible. Try to imagine all sorts of situations, developing imaginative thinking.

Doctors advise food in small portions, but 4-5 times a day. This way you keep the blood flow to the brain. If you eat large portions 1-2 times a day, then the energy of the body to digest this food, and there will be little left for the brain.

No wonder they say that excessive smoking is injurious to health. If you are planning to upgrade level IQ - Give up or reduce the number of cigarettes you smoke. Tobacco smoke helps to reduce oxygen consumption by the brain, and, consequently, the deterioration of brain activity.

  • What books should you read to improve your intelligence?

In the fifties, the IQ test became wildly popular in Europe, and its author became a celebrity. Everyone was measured by intelligence: both in offices and in a friendly circle. An expression like "He has a low IQ" has become a euphemism for "He's a fool." Which, by the way, is far from the truth. After all, intelligence is defined as a set of cognitive abilities of a person, which testify to his level of thinking and ability to decide challenging tasks. Therefore, the task of intelligence tests is to identify what type of thinking is most developed in a person - figurative, logical, verbal, etc., as well as to assess his memory, level of development, attention.

Myth one

The final score you get on an IQ test is an indication of your intelligence and ability.

Actually

The Eysenck test contains several sections (the so-called subtests) - for abstract, verbal, figurative thinking, etc. The results of the subtests are summed up, and as a result an average value is given. Consequently, for a person who has outstanding imaginative thinking and, say, a very unimportant logical final result of the IQ test, it will turn out to be so-so.

Myth two

The higher the IQ, the smarter its owner.

Actually

There is a joke that, they say, high Eysenck test scores do not indicate a person’s intelligence, but only his ability to pass intelligence quotient tests well. In every joke there is only a fraction of a joke. After all, points IQ is 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 neither to the practical mind, nor to creativity they are not related.

Myth three

A person with a high IQ is more likely than others to succeed in life.

Actually

In the preface to one of the popular editions of the IQ test, Eysenck wrote that in order to achieve success in life, high performance intelligence in without fail perseverance and high motivation must be applied. A person with high intelligence, but devoid of perseverance, runs the risk of spending his whole life waiting for "his hour". A person who is persistent in cognition, but not motivated by any goals, runs the risk of not getting up from the couch. Sadly, the combination of perseverance plus motivation has the greatest chance of success, even in the absence of a pronounced intellect.

Myth four

If a person's IQ is above 170, he is a genius.

Actually

In professional IQ tests, the highest score is 144. A result that exceeds this number is not very detailed, falling into the values ​​\u200b\u200bof "from 150 to 160" or "from 160 to 170", etc. However, Eysenck tests always give clear results. posted on the Internet.

Myth five

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

Actually

All tests posted 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 definitely add: "against the background of a group of third-graders." The professional IQ test is reviewed every few years by psychologists and adjusted for the Flynn effect.

Myth six

IQ is a constant value.

Actually

First, it is necessary to distinguish between real intelligence and IQ test scores. Actual abilities may vary slightly depending on mood, well-being and even self-esteem. As for the problems from the test, you should always remember: the situation in which the person being tested is somewhat artificial. A person may misunderstand poorly formulated or poorly translated into Russian (there have been such cases) the conditions of the assignment. In the middle of the test, he may lose interest in this activity or be inattentive. And vice versa: you can practice solving problems from the Eysenck test so that they bounce off your teeth. But this is by no means an indication that his intelligence has increased unspeakably.

Myth seven

There is a certain organization in the world that is more secret than the Masonic Lodge, to which people with IQs exceeding 170 belong. All of them are the princes of this world: heads of large corporations, influential politicians, well-known public figures. However, if you are a janitor with an exceptionally high intellect, sooner or later this organization will notice you, take you under its wing, and then you will have an outstanding career.

Actually

It is even a little embarrassing to expose this myth with a humanistic background. May 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 (http://www.mensa.org). It has nothing to do with power over this sinful world; Mensa is more of an educational activity. But there is only one way to join this international brotherhood: to pass the notorious IQ test and show outstanding results.

How do people with low intelligence think?


David Stewart

teacher

“I work at a school for children with mental retardation. All of them were tested and the results showed that their IQ is below 70. Educational program, designed for ordinary children, does not suit them. When I talk about them, people think that my day is completely filled with dealing with idiots. Everyone imagines this as a constant struggle with cavemen who bang their heads against the walls and yell "My brain hurts!" when I ask the students to remember proper names. But the truth is that if you put such a teenager in the same class as "normal" children, you would not notice the difference. In most cases, their thinking is the same as that of ordinary children. They grab their phones when they hear a call, read text without articulated lip movement, and answer as quickly as other kids their age.

I have a student who could take on any other kid of his age in football team knowledge. He can tell you everything about the team's current roster, its achievements over the years, and the current season's games in detail. He is not a scientist with a photographic memory, he is just a teenager who is fond of football and is no different from his peers. Some of the guys I teach are crazy about Minecraft, have mastered the game in the original and a few modified versions. Some students are fluent in two languages. One girl taught herself English in a year by watching Australian television. She learned the language in her native country, but began to speak it fluently, like her peers, through her own efforts and practice.

You can see the difference when you try to teach these kids new things. Most often they need to repeat new material large quantity times than their peers, and they don't always immediately remember what you think they already understood. They often need to explain something new with several examples before they absorb the information. But in most cases, they think in exactly the same way as you and I, and sometimes they can even be smarter in some matters. The idea that a difference of 20 IQ points or so is the difference between a normal human being and another life form with a differently functioning brain is simply not objective.”

“If you don't get enough sleep, your IQ goes down. So you can see for yourself after a few sleepless nights. True, due to lack of sleep, you get tired and your mood worsens, so the comparison is not entirely correct. Be that as it may, before the exam it is better to get enough sleep.


R. Eric Sawyer

funeral director

“I had to work the night shift with a person who had quite pronounced physical limitations - and this is at a job where remarkable strength is required. But in fact, he was my "savior." Johnny could only do 70% of what a normal person of his height and weight can do, and because of this, many thought that he was a burden to them. But Johnny gave his 70% all the time, for every job and every shift. You would get everything he can from him.

I managed trainees, some of whom were real athletes. These people, who had from 100% to 110% of the capabilities of an ordinary person, sometimes need to be sought out in order to do this or that work. And Johnny himself was looking for a job. "Normal" people gave only half of what they could. But I'd pick that 70% Johnny on any given day, not the 50% of the guys who are 100% capable. That puts me 20 points ahead.

In my experience, low and high IQ people sometimes work the same way. Show me someone not so gifted, but interested and motivated, who tries to get to the bottom of the truth and listens carefully to others. I will always prefer such a person instead of a smart guy who thinks that he is a genius, that he has nothing more to learn and that everyone should listen only to him.


Quora user

Let's say there are two guys in football team, Bill and John. John is an athlete who is good at any sport, while Bill must work all the time in order to achieve success. Time passes, John only relies on the skills he already has, while Bill trains every day. Bill is enthusiastic about the game, while John sees it as just another sport. For a long time, John performs better than Bill, but finally Bill overtakes John. And all because while John did nothing, using his innate talent, Bill persistently and enthusiastically achieved his goal.

The same goes for the level of intelligence. IQ is a measure of the potential you have to excel at problem solving, thinking, and the like. But this is not the only success factor. With enough perseverance and hard work, a person with a lower IQ will overtake a person with a higher IQ if they don't put in the effort. In the end, it's not what you have that matters, but how you use it."

50% of people have an IQ level of 90-110 - the average level of intelligence.
2.5% of people have an IQ level below 70 - they are mentally retarded.
2.5% of people have an IQ level above 130 - I consider such people with a high level of intelligence.
0.5% are considered geniuses, they have an IQ level above 140.
Although the debate about who is considered smart, and whether IQ determines mental ability, continues.

Text: Ilya Yanovich

The idea of ​​measuring human intelligence with relatively simple test appeared more than a hundred years ago and has since fallen into different hands. United and universal test on IQ does not exist, but a similar technique is still resorted to by some employers in interviews, and supporters of the far right, who are trying to scientifically prove the theory of racial superiority.

However, some time ago, scientists noticed that the average IQ in developed countries from the UK and Denmark to Australia began to fall, although it has been growing steadily for the past 80 years. We figure out whether the IQ indicator is important at all and what it really says about a person.

What affects our
mental development

New Zealand political scientist James Flynn was the first to notice the relationship between standard of living and IQ. The development of science and education, new inventions, improvement of living conditions, health care, nutrition, reduction of crime - these are some of the factors that affect intellectual development.

The so-called Flynn effect is confirmed by almost all local studies. For example, in Denmark, all people preparing to become military men must pass an IQ test - and this has been the case for more than 60 years, and the test, adapted in the middle of the last century, was updated only a few years ago. At the same time, the average result grew every year: with those scores that were considered the norm in the 1950s, today you may not be accepted into the service. Growth continued until the end of the 1990s, in the 2000s the numbers froze, fluctuating slightly in one direction or the other, and now they have gone down. And not only in Denmark: many universities and research centers around the world report similar results.

At first glance, there is no logical explanation for this: according to the Flynn effect, growth should only gain momentum. Moreover, scientists from the University of Otago - the one where Flynn conducted his research - add information flow to growth factors. The number of newspapers and magazines in the middle of the 20th century increased many times over, television appeared at the same time, and people, constantly passing large amounts of data through their heads, learned to more easily absorb any information. new information. The drop in numbers coincided with the massive spread of the Internet, which is even more confusing.

Flynn himself has two explanations for this phenomenon. The first version - according to statistics in developed countries, wealthy and relatively successful couples are increasingly having one child, while many families with many children live near the poverty line. Parents there have not received proper education and cannot afford to pay for college or university for their children, and poor living conditions, according to the same Flynn effect, lead to a drop in intelligence. This hypothesis, firstly, requires additional research, and secondly, is consistent only if the genes really affect the level of IQ.

Genes do influence IQ levels, and significantly, according to the results of a study by American psychologist Robert Plomin. But this assumption has many opponents: allegedly Plomin and his colleagues did not provide convincing evidence in favor of the fact that from good families smart children come out because of genetic connections, and not because of the comfortable environment around them.

Flynn's second version: high level life has long become the norm for most developed countries, today this level is growing slightly or not growing at all, which is why the average IQ is no longer rising.


What IQ Tests Really Measure and Why They're Not Universal

A test very close to what we now understand as an IQ test was developed in 1912 by the German psychologist William Lewis Stern. He took as a basis different tasks and puzzles of the 19th century and tied them to his system of studying child psychology - the result partially resembled that developed in parallel by Alfred Binet psychological test. In fact, Stern wanted to create a methodology for assessing developmental potential in children, but all subsequent IQ tests (including tests of ambiguous British psychologist Hans Jurgen Eysenck, who popularized the very idea of ​​measuring IQ) suggested variations for adults.

The test, during which you need to answer 40 questions in 30 minutes, is too outdated and inaccurate. But he got so deep into the universities research institutes, and now on the Internet, that they still cannot weather it. If you took an IQ test at school, it must have been one of the many variations of the Eysenck test. At the same time, a standardized test has not appeared for more than 100 years: there are several dozen main options (Kettel, Wexler and other psychologists), as well as several hundred of their modifications - and this is if we take into account only the tests used by major scientists, and do not take adapted versions for different ages.

Most likely, each of us passed the IQ test, at least out of interest, but many find it difficult to answer what exactly it measures. The most popular answer is some kind of conditional "mind". In fact, an average IQ test measures your ability to analyze new information (both using and not using old information) relative to your age. At the same time, tests are specially designed in such a way that the average value is equal to 100 points. It is believed that a result below 70 points indicates problems in mental development, but the so-called genius threshold varies greatly from version to version: somewhere it starts from 140 points, somewhere from 160.

The man with the highest IQ in history is considered to be the American William Sidis, who was born in 1898. A writer, asexual, political activist, he read the Iliad in the original at the age of three, knew several dozen languages ​​by the age of majority and invented one of his own, was incredibly capable in mathematics, published several fantastic books and monographs on different topics. Accurate data on his IQ was not preserved, but, according to unconfirmed reports, reached a corridor of 250-300 points. However, his only pragmatic invention, " perpetual calendar", today no one uses it.

A smart and successful person in all visible respects with an ordinary
or even low IQ is far from an exception

By taking the same test with short breaks, you can get different results because concentration is significantly affected by your physical and psychological condition. But even in potentially sterile conditions, IQ tests are far from high precision. For example, a variant of the Eysenck test, long used in the United States to test preschoolers between the ages of 3 and 5, asked what color an apple was. The correct answer is to say that there are many colors and name some of them, but it is highly likely that a three-year-old child could see only red or only green apples, and it does not affect his mental abilities in any way.

Some versions of the Rudolf Amthauer test even ask erudition questions (“what is measured in joules?”) - the answer can be found in a second on the Internet or in a directory, which is why you will not become more capable. Psychologist W. Joel Schneider, in an interview with Scientific American, also recalls that the average IQ test gives not only a very approximate, but also a very average value, because it consists of several subtests, each of which checks different types thinking. Thus, a person with outstanding abstract thinking and weak verbal highly likely will get an average result.

Research centers use more advanced systems that produce not only an average score, but also very detailed statistics. Schneider himself developed one such program called the Compositator, although he admits that it is far from the required accuracy, and a smart and successful person in all visible parameters with an ordinary or even low IQ is far from an exception. In his blog, largely dedicated to measuring IQ, Schneider notes that public interest in IQ tests and their results is declining: they are no longer taken too seriously. This is especially noticeable in American employers: in the 50s, when IQ measurement became popular, large companies they wanted to hire only people with high scores and even arranged tests right at the interview, but by the 2000s, this practice was almost completely abandoned.

Finally, another important problem with IQ tests is strict timing. It is known, for example, that Albert Einstein thought extremely slowly and did not fit into the allotted time for exams, but hardly anyone would doubt the level of his intellectual abilities.


Is high IQ important?

There are several organizations that bring together people with extremely high IQs. Mensa International will accept those whose score is higher than 98% of the population (that is, two out of a hundred people). Although you still need to pass not a standard IQ test, but a specially revised one. The Prometheus Society is much stricter: their tests are designed in such a way that only one person in 30,000 can pass them. The organization is growing very slowly: in 2013 it had only about 130 members.

The Mensa site allows you to participate in an intellectual exercise - take a test of 30 questions per hour. This is not a traditional IQ test, nor is it an admissions test for Mensa. You are warned that the test was created for entertainment purposes only, but based on the same questions and methods for assessing intelligence as the real Mensa exam, which is not in the public domain. Many tasks resemble the Eysenck test, but at the end they will describe in detail the methods for solving questions and the most common mistakes you made.

There are no extraordinary achievements among the members of Mensa and Prometheus. 68-year-old American journalist Marilyn vos Savant, member of Prometheus and Guinness World Record holder for IQ scores from 1986 to 1989, writes a column for Parade magazine, solves logical paradoxes, published several books and wrote several plays. But you might not have heard of her at all, although according to the test results, she is the most prominent woman in history. The latest Guinness World Record holder, Korean Kim Un-young, quickly mastered mathematics and foreign languages, solved problems for speed in local television programs, but by his 51st year he also did not mark anything truly significant. In 1990, the Guinness Book of Records stopped including IQ champions in their publications at all, explaining that there were too many tests, they all give different results, and it was impossible to determine the winner.

While the average IQ is indeed falling across the developed world, it hasn't really affected anything, says Thomas Tiedl, a professor at the University of Copenhagen and the same scientist who noticed the decline in the average IQ of the Danish military. The number of scientific publications is growing, an increasing percentage of people receive higher education, the pace of technology development is increasing every year, and it is not very clear whether the average IQ value can even affect anything other than statistics. So don't give too much great importance some random numbers.
