Who has the first iq. What is the highest IQ in the world

The IQ level is considered an indicator of a person's intellectual abilities. It is by him that it is estimated how successful a person will be in school and how successful his career will be.

An IQ below 70 is typical for people with very low level intellect. The average level of intelligence is determined within 90-110 IQ. Half of the people on the globe have just such indicators. If a person has an IQ of 110-130, this indicates a high level of development, good memory, and concentration.

However, there are those who have an IQ level of 130 or more. People with the highest IQ in the world are incredibly talented and smart, often they become scientists and achieve heights in their chosen profession. These are real geniuses of their era, creators and inventors, who have many achievements to their credit. What is the highest IQ? The list of people who have a high IQ is presented below.

Stephen Hawking - IQ 160, (01/08/1942)

Stephen Hawking does not have the highest IQ, but everyone knows his name, even those who are not particularly interested in science and physics. All this because Hawking is an incredibly charismatic and interesting person, a British theoretical physicist, who has many scientific works, seven of which became bestsellers. His contribution to the study of space cannot be estimated, many modern theories based on the research of Stephen Hawking. The scientist and public figure also writes books about science for children. Two films were made about his life and contribution to science, in which cult actors Benedict Cumberbatch and Eddie Redmayne played the scientist.

Despite the fact that Stephen Hawking was diagnosed with amyotrophic lateral sclerosis, a severe diagnosis due to which he became paralyzed and lost the ability to speak, the scientist continues to lead an active lifestyle and communicate with people using a special computer. He constantly participates in media projects and various scientific conferences, declaring the need to explore space, as staying on Earth is becoming more and more dangerous for humanity. Stephen Hawking always spoke about the level of his IQ with irony, as he is convinced that the test does not give an accurate assessment of the intellectual abilities of a person and that boasting about him is the lot of losers.

Paul Allen - IQ 170 (01/21/1953)

The American entrepreneur did everything possible to earn a fortune on his intellectual abilities and he succeeded, Paul Allen's fortune is estimated at $ 14.2 billion. One of the richest people on Earth is a co-founder of Microsoft. Along with Bill Gates, Paul was involved in technical development and devoted most of his time to the development of the company. Due to mutual conflicts with another co-founder, Paul Allen was forced to leave the company and concentrate on investing. Today, the businessman is one of the founders of Stratolaunch Systems, an aerospace company, and also owns several sports clubs.

Andrew Wiles - IQ 170 (4/11/1953)

The brilliant mathematician was born in England, but moved to the USA in 1982. The owner of a high IQ level in 1995 managed to solve the most difficult mathematical problem and thereby prove Fermat's Last Theorem. For this, in 2016, the great scientist received the Abel Prize, founded by the Norwegian government, which is awarded only to the most outstanding mathematicians of our time. The result of the scientific work of Andrew Wiles was the receipt of 15 awards in the field of science. Andrew Wiles is currently Professor of Mathematics at Princeton University.

Judit Polgar - IQ 170 (July 23, 1976)

Judit is not only an attractive woman, she is a talented chess player who, at the age of 15, managed to surpass Bobby Fischer's record and become the youngest grandmaster in history. The champion did not go to special chess clubs, she studied with her father from childhood, who was sure that home education from an early age would ensure her daughter's achievement of great heights in her career. By the way, the owner of a high IQ is the only woman who is included in the first hundred chess players in the FIDE rating, where players get on the basis of tournaments. Since 1989, Judit Polgar has been at the head of the rating list of female chess players.

John Sununu - IQ 180 (July 2, 1939)

The famous American politician was born in 1939 in Cuba. To get a decent education, as a young man he moved to the United States. There, John managed to graduate with honors from the Massachusetts Institute of Technology, receiving three degrees and becoming a Ph.D. However, Sununu is best known not for his scientific work, but for his incredible political achievements. From 1983 to 1989, he was elected governor of New Hampshire, and then became the head of the presidential administration, a position he held until 1991.

Garry Kasparov - IQ 190 (April 13, 1963)

The Soviet and Russian chess player is considered the greatest player in the history of chess, thanks to the fact that he managed to become the youngest champion in the world at the age of 22. And until now, Garry Kasparov holds this title. In 2005, the athlete decided to end his career and became a prominent political figure, and also began to regularly write books about the art of playing chess. Garry Kasparov is the only chess player who managed to achieve a draw in a game against a computer.

Richard Rosner, IQ 192 (5/2/1960)

This is one of the most eccentric men with one of the highest IQ levels. Despite a considerable level of intelligence, Richard did not become a scientist. The genius works as an ordinary television producer and is proud of the fact that in his life he managed to work as a waiter, a security guard, and even a stripper. Rosner was on Who Wants to Be a Millionaire and took the case to court, believing that one of the questions asked of him contained a mistake. Unfortunately, Richard Rosner failed to prove his case.

Christopher Langan, IQ 195 (1952)

In many media and television shows, Christopher is presented as the smartest person in the United States, while he did not graduate from prestigious universities and studied independently, studying everything necessary items. According to the results of tests to measure the level of IQ, Christopher Langan's intellectual abilities are estimated in the range of 195-210. The genius had a difficult childhood. The boy was incredibly gifted, from the age of 6 he began to talk, at 4 he began to read on his own, while his mother did not do it at all, and his stepfather constantly beat him. As a young man, Christopher ran away from home and began to train hard in the gym, lifting weights. Thanks to excellent physical data, Christopher Langan managed to get a job as a bouncer in a bar, where he worked for a long 20 years. For the first time, the genius became known in 1999, when Esquire magazine published a list of the smartest people. Christopher Langan attracted attention for his work as a bouncer, while being the author of various scientific papers. Now articles about the scientist are regularly published in magazines, and he is also one of several organizations that unite smart people.

Kim Ung-Yong - IQ 210 (03/07/1963)

A famous scientist with one of the highest IQs in the world was born in South Korea. From childhood, the boy surprised his parents and those around him with incredible abilities, becoming a recognized child prodigy. While other babies were just starting to crawl, Kim was already starting to talk. At the age of two, he was fluent in two languages, at three he could read text in several languages, and at 4 he was able to solve simple mathematical problems. At the age of four, Kim Ung-Yong passed an IQ test and earned 200 points. It is worth considering that according to the rules, such a knowledge test is carried out only for seven-year-old children. An incredibly gifted boy from Korea caught the attention of NASA and soon Kim Ung-Yong was invited to study in the United States. Kim did not leave Korea to pursue a career as a scientist, but became a civil engineer when he returned to his homeland in 1978.

Highest IQ in history - Marilyn vos Savant, IQ 225 (08/11/1946)

The famous writer and playwright from the United States has the highest level of intelligence among living people. This fact was officially established and entered in 1986 in the Guinness Book of Records. She began taking tests to determine the level of intelligence from the age of 10, each time improving her performance. Now Marilyn lives in New York and is married to a famous cardiac surgeon and scientist, the creator of an artificial heart - Robert Jarvik. The person with the highest IQ holds the position of Chief Financial Officer of Jarvik Heart and is constantly involved in matters relating to the study of cardiovascular disease. In addition, Marilyn vos Savant writes a column in the most famous Parade magazine, in which she answers questions from readers. It is quite difficult to accurately determine the level of intelligence of an American writer and scientist, since there are several tests to determine IQ. Marilyn's highest result was 228, thanks to which she got into the Guinness Book of Records as the smartest person. But again, this result lends itself to criticism from the outside, since the IQ test is not considered an indisputable confirmation that a person has high intellectual abilities and can be considered the smartest.

Today, Marilyn vos Savant is a member of the Prometheus Society and the Mensa Society, non-profit organizations that bring together people with a very high level of intelligence.

Finally

Among the people with a high IQ in the history of mankind include such geniuses as Leonardo da Vinci, Nikola Tesla, Albert Einstein, Nathan Leopold and William James Sidis. All of them left a significant mark in history, made an invaluable contribution to science. Their phenomenal intellectual abilities simply amaze the imagination of the average person. How can this be achieved? Most likely, this is laid down at the genetic level. How else to explain the fact that a child begins to talk in infancy or to read, when his peers still have no idea about it? Interesting, unbelievable, but true...

All people living in the world are different. This statement applies to the intellectual level as well. Almost everyone considers himself smart, but a person cannot objectively assess his intelligence. Of course, the thoughts in your head always sound very smart, but there are several signs of high intelligence in a person, as well as features of a low IQ.

Intelligence, both mental and emotional, is very important. Especially in a professional context, a developed and flexible mind can be the best prerequisite for success in life. “A person with low intelligence often has habits that can lead to disastrous consequences,” writes The Independent. So, people with a low degree of intelligence ...

Blaming others for their failures

This habit is expressive, unprofessional, not characteristic of a person with a high IQ. Attempts to blame other people for your failures characterize not the smartest person. People with low IQ prefer not to be responsible for wrong decisions, it is better for them to “bask” in self-pity or simply blame others for everything.

T. Bradbury, author of Emotional Intelligence 2.0, says: “Don't blame or shift responsibility to someone else. If you played a role - even the smallest one - in a particular case, and something went wrong, admit it, ”says Bradbury. “Once you start blaming others for your failures, people around you will begin to perceive you as a person who is not responsible for your actions.”

An indicator of high intelligence is the recognition that a mistake is a chance to gain new experience. J. S. Moser of the University of Michigan, in the course of his research, came to the conclusion that the brains of smart individuals react to mistakes and failures in different ways.

Always prove themselves right

In a controversial situation, intelligent people are more likely to take the opponent's place, understand his arguments, integrate them into their thought chains, and reconsider current views. A clear manifestation of intelligence is the ability to look at things from a different point of view, to understand them. Intelligent people are open to new information, changes in generally accepted principles.

On the contrary, people with low mental abilities continue to argue, do not give in from their position, not understanding the existing arguments, do not notice the mind and competence of the opponent. This overestimation of oneself is called the Dunning-Kruger effect. This is a cognitive bias that causes less competent people to overestimate their own abilities while underestimating the intelligence of others.

A smart person also proves his case, but he knows how to listen, consider the available arguments, basing the final decision on them.

Angry and aggressively react to disputes

Of course, a high level of intelligence is not determined by constant calmness; even the most intelligent people get angry. But for a low IQ, aggression is literally synonymous with getting out of a situation that is not going according to their plan. When there is a feeling of not being in control of the situation according to their ideas, such people tend to use anger to prove their position.

Scientists from the University of Michigan in the course of the study clearly showed the relationship between aggression and low IQ. In their final report, they stated: “It seems to us that people with low IQ react aggressively from an early age. Such angry manifestations complicate the mental and social development of the child, leading to the appearance of certain disorders.

Pay no attention to the feelings of others

An intelligent person can put himself in the place of others, which allows him to understand their position. R. James of the University of Texas, in a study of 1,000 Americans, found that highly intelligent people often offer help without expecting anything in return. Therefore, scientists believe that the ability to take into account the needs of others makes smart people prone to helping.

“Individuals with developed mental abilities can understand the feelings of other people,” the study says. It is difficult for people with low IQ to imagine that someone could have a different opinion, so they do not agree with it. In their minds, the idea of doing something for someone else without expecting kindness is strange to say the least.

Consider themselves the best

Intelligent people can help others without fear of being left in the shadows. They have a healthy level of confidence and intelligence needed to accurately assess their competence. On the contrary, people with low intelligence tend to slander others in order to put themselves in a better light. According to scientists, prejudice is not a symptom of a good IQ.

In a study conducted at Brock University (Ontario), scientists found that "people with low intelligence often demand harsher punishments, are more homophobic, and among them are more racist." According to biologists, the ability to cooperate has played an important role in general development humanity. This suggests that one of the most important features of IQ is the ability to work well with others.

Surprising Signs of Intelligence

However, according to expert research, there are other interesting factors that can show that your intelligence is beyond mediocrity. Learn how to understand that you have a high intelligence; see if any of the amazing scientifically proven signs of a good IQ apply to you.

You are the first born

If you are the oldest child, congratulate yourself. A new study from the University of Edinburgh has found that first-born babies have higher IQ scores than their younger siblings. What connection can there be between firstborns and exceptional mental abilities?

Specialists observed 5,000 children from birth to 14 years old, and every 2 years they assessed how children read, write, solve word and mathematical problems. Scientists have found that despite the same emotional support given to children by parents, first-born children receive more tasks that improve their thinking.

you swear

Most people associate swearing with a lack of intelligence and good manners, but, surprisingly, harsh language can sometimes indicate high intelligence. Scientists at Marist College in New York have highlighted the link between "strong language" and IQ.

They asked volunteers to say (either orally or in writing) as many words as possible from different categories, such as obscenities, animals, words starting with a certain letter. After evaluating the results, the experts learned that the people who managed to write the largest number everyday concepts included more swear words on their lists.

Experts explain this in such a way that obscene words expand vocabulary, and the correct use of a wide range of words is a sign of increased intellectual abilities.

Do you have the concept of black humor

The next sign of high intelligence in adolescents (usually from 16-17 years old) and adults is the concept of black humor. A slightly distorted sense of humor, which is not understood by everyone, according to Austrian scientists from the field of psychology, indicates high intelligence. They asked over 150 people to rate cartoons that included dark humor. Then they measured their verbal and non-verbal intelligence, mood swings, aggressiveness. Participants who preferred the most vulgar jokes had higher levels of both types of intelligence, were less aggressive than people who preferred traditional forms of humor.

According to scientists, the reason is that for the concept of a vulgar joke, it is necessary to use all the mental power, which not everyone can do. Black humor is much more complex than a typical joke, so good thinking skills are needed to appreciate it.

Your mother suffered from nausea during pregnancy

Unpleasant nausea during pregnancy affects almost all expectant mothers, but its intensity can be an indicator of the intelligence of their children. Researchers from Toronto, Canada studied mothers-to-be during pregnancy and then their children after birth.

The experts found that the children of women who suffered the most from morning sickness during childbearing later scored higher on IQ tests than the children of mothers who did not spend every morning hugging the toilet.

Scientists have linked this phenomenon with the levels of the mother's hormones, estradiol and prolactin. Women with morning sickness expose their babies to higher levels of these hormones, which can lead to increased fetal brain development.

you are an owl

Do you like the rhythm of an owl? In this case, according to a British study, you are smarter than people who prefer to live according to the opposite rhythm (larks). Specialists in the course of an 8-year study observed 20,000 teenagers, and came to interesting conclusions.

People who go to bed later than their peers are smarter and have higher IQs. Scientists believe that individuals with advanced mental abilities were able to change their natural circadian rhythm (a term better known as the internal clock), causing them to go to bed earlier.

Our ancestors instinctively slept at night to avoid nocturnal predators, but smart, modern humans evolved around these risks, adapted to the hours of the night, which the ancestors could not do.

In order to increase IQ, one should not change the circadian rhythm. Enough brain training, memory, attention. Also, remember that most healthy people should sleep at least 7-8 hours.

You are an introvert

You don't like the big city, you don't like going to parties, you feel uncomfortable in a crowded bar? These signs, characteristic of introverts, indicate increased intelligence. A British study of 15,000 adults found that those with good IQ scores were less satisfied living in a densely populated area.

In addition, these people reported greater life satisfaction when spending less time with friends than people with lower IQs. The introverted way of thinking evolved along with evolution - our ancestors lived in tribes, and socialization was often necessary for survival, the researchers explained. But smart people have probably gone beyond "tribal support." This means that they can adapt to today's rapidly changing society, regardless of their peers.

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 reduces the consumption of oxygen by the brain, and, consequently, the deterioration of brain activity.

Books for the development of thinking

L. Hubbard in his book "The Theory of Learning" says that the ability of an individual to acquire knowledge depends on his readiness to independently highlight the main points in the text. Learning to learn is the main task of the pedagogical process. If a person knows how to seek knowledge, then he will be able to update them throughout his life.

Analytical thinking will help develop works written by eminent philosophers such as I. Kant, Plato, Socrates, F. Nietzsche, Hegel, etc. Their writings will help to understand the basic laws of the development of human thinking, the types and forms of consciousness.

Reading is equally important. fiction. Considering the behavior of characters in certain situations, a person develops new forms of behavior for himself. Works based on psychology, philosophy, history, help to expand consciousness and develop imagination. The classic works that require mandatory reading include the books of F. Dostoevsky "Crime and Punishment", M. Bulgakov "The Master and Margarita", L. Tolstoy "Confession", A. Camus "The Rebellious Man", Sartre "Nausea", M. Prishvin "Forget-Me-Nots".

Books for the development of memory

In the book by O.A. Andreeva “Memory development technique. Self-Teacher" presents exercises for training all types of memory. The author invites the reader to distribute the tasks of certain techniques in such a way as to achieve the maximum effect. Complex exercises will help improve those functions of your brain that remember and store information.

The book “Memory cards. Getting ready for exams ”T. Buzan is a set of specific methods for memorizing information. The author gives practical recommendations that help to cope with stress during complex tasks.

Zack Belmore in his book "The Basics of Mechanical Memory" presents the reader with exercises that will help develop the ability to memorize a huge text in short periods of time. The work talks about how to increase brain activity, make the process of memorization arbitrary. The book consists of several chapters, each of which is devoted to a certain age period.

In E. Bongo's book "Self-Tutorial on the Development of Thinking", the reader will be provided with a five-stage methodology. Successive passage of each step will lead to a high level of memory development.

What books should you read to improve your intelligence?

You may not be the neatest worker, and your partner complains that you never go to bed together. But there is a chance that your intelligence is above average. Check if there are any matches.

1. You are left-handed

In a right-handed world, left-handedness seems like a dubious advantage. Left-handers have to use different scissors, change the location of the mouse at the computer, and put up with superstitions and prejudices. A study last year found a significant association between left-hand dominance and math performance (although there is also a strong association with age, gender, and job type).

2. You are not neat

Managers and office workers need a clean desk like air: one lost document can turn into a headache for the whole company. But if your job involves product development, graphic design, or writing articles, a cluttered workspace can spur creativity.

Researchers from the University of Groningen have come to the conclusion that the surrounding space significantly affects the nature of our thinking. For example, if we see that there is chaos around, the brain unconsciously switches to sorting information, so thinking becomes clearer.

3. You use foul language

Those who are accustomed to seasoning their speech with strong expressions are often considered narrow-minded people. But psychologists have found that knowledge of swear words and the ability to use them is rather a plus. The subjects with the highest IQ and the largest vocabulary recalled the most swear words in a minute.

Humor signals that the speaker is resourceful, able to think outside the box and treat problems philosophically.

"We judge a person's intelligence by the way they speak," write Christine and Timothy Jay, psychologists at the Massachusetts College of Art. But this judgment is not always accurate. The use of taboo vocabulary is associated with a whole bunch of negative characteristics: lack of education, poor self-control, aggressiveness. It is not always so".

4. You know how to make others laugh

“There is a strong relationship between a sense of humor and high intelligence,” explains Jill Greengross, a psychologist at Aberystwyth University. She and her colleagues found that the strongest connection was with verbal intelligence, since humor is based on verbal paradoxes.

“It is no coincidence that humor is considered sexually attractive,” the psychologist comments. “It signals that the speaker is resourceful, able to think outside the box and treat problems philosophically.”

5. You are a night owl

Despite the fact that due to the violation of biological rhythms, night vigils can adversely affect health, studies show that, compared to "larks", "owls" maintain concentration longer and get tired more slowly. In addition, on average, they earn more and occupy higher positions.

6. You love black humor

Morgue. Body identification. The surgeon lifts the sheet. Woman: "Yes, that's definitely my husband. By the way, what powder do you wash the sheets with? So white!" This joke is not for everyone. However, according to a study by Australian psychologists, fans of such humor, on average, demonstrate a higher level of intelligence compared to the rest.

Where this connection comes from is not entirely clear. It can be explained by the fact that during the "decoding" of a joke, we involve complex cognitive processes. True, whatever the level of intelligence, a bad mood reduces the ability to understand black humor, as well as normal.

7. You tend to worry a lot

A consolation for those who see endless problems in the future: at least their intelligence is developed enough to find a solution. Psychologists from Lakehead University (Canada) found that those who constantly replayed negative situations from the past in their heads or worried about the future scored high on a test of verbal intelligence.

A higher IQ level is observed not only in first-borns, but also in general in older children.

True, the same study found that non-verbal intelligence (social and emotional) in these people is reduced. It is probably better for them to choose the role of advisor or analyst.

8. You are self-critical

A phenomenon known as the Dunning-Kruger effect: less competent and intellectually developed people tend to exaggerate the degree of their understanding of the problem (as well as the level of development of their mental abilities in principle), while experts and intellectuals, on the contrary, are more likely to doubt themselves. However, Socrates spoke about this: I know that I know nothing.

9. You love cats

In a dispute between cat lovers and dog lovers, the point goes first: a 2014 study clearly showed that cat lovers are more open-minded and have a subtle taste. In turn, those who prefer dogs are more energetic and easy-going.

10. You are the oldest child in the family.

A higher level of IQ is observed not only in first-borns, but also in general in older children. Professor Petter Christensen of the National Institute of Occupational Health in Oslo believes that this connection is due to social rather than biological reasons. Seniors usually have to be more collected and responsible. This probably affects their attitude towards learning.

The Australian mathematician, the author of the Green-Tao theorem, has the highest IQ level, his name is Terence Tao. Getting results over 200 points is a very rare occurrence, because most of the inhabitants of our planet barely score 100 points. People with extremely high IQs (over 150) can be found among Nobel laureates. It is these people who move science forward, make discoveries in various professional fields. Among them are the American writer Marilyn vos Savant, the astrophysicist Christopher Hirata, the phenomenal reader Kim Peak, who can read a page of text in a few seconds, the Briton Daniel Tammet, who memorizes thousands of digits, Kim Ung-Yong, who studied at the university at the age of 3, and other famous personalities. with amazing abilities.

How is a person's IQ formed?

IQ levels are influenced by several factors, including heredity, Environment(family, school, social status of a person). The age of the test subject also significantly affects the result of passing the test. At the age of 26, as a rule, a person's intelligence reaches its peak, and then only decreases.

It is worth noting that some people with exceptionally high IQ in everyday life turned out to be completely helpless. For example, Kim Peak could not fasten the buttons on his clothes. In addition, not everyone has such a talent appeared from birth. Daniel Tammet gained his ability to memorize vast numbers of numbers after suffering from a terrible epileptic seizure as a child.

IQ level above 140

People with IQs over 140 are the owners of excellent creative abilities who have achieved success in various scientific fields. Famous people with an IQ score of 140 or more include Bill Gates and Stephen Hawking. Such geniuses of their era are known for their outstanding abilities, they make an incredibly high contribution to the development of knowledge and science, create new inventions and theories. Such people are only 0.2% of the total population.

IQ level from 131 to 140

Only 3% of the population has a high IQ. Among famous people, with a similar test result - Nicole Kidman and Arnold Schwarzenegger. These are successful people with high mental abilities, they can reach heights in various fields of activity, science and creativity. Want to check who is smarter - you or Schwarzenegger?

IQ level from 121 to 130

The intellectual level above the average shows only 6% of the population. Such people can be seen in universities, as they are usually excellent students in all disciplines, successfully graduate from universities, realize themselves in various professions and achieve high results.

IQ level from 111 to 120

If you think that the average iq is about 110, then you are wrong. This indicator refers to intelligence above average. People with test scores between 111 and 120 are usually hardworking and have a life long pursuit of knowledge. There are about 12% of such people among the population.

IQ level from 101 to 110

IQ level from 91 to 100

If you passed the test, and the result was less than 100 points, do not be upset, because this average is in a quarter of the population. People with such indicators of intelligence study well at school and universities, they get jobs in the field of middle management and other specialties that do not require significant mental effort.

IQ level from 81 to 90

One tenth of the population has a level of intelligence below average. Their IQ test scores are between 81 and 90. These people usually do well in school, but most often do not get higher education. They can work in the field of physical labor, in industries that do not require the use of intellectual abilities.

IQ level from 71 to 80

Another tenth of the population has an IQ level of 71 to 80, which is already a sign of mental retardation of a lesser degree. People with this result mostly attend special schools, but may also graduate from regular schools. primary school with average marks.

IQ level from 51 to 70

About 7% of people have a mild form of mental retardation and an IQ level of 51 to 70. They study in special institutions, but they are able to take care of themselves, and are relatively full members of society.

IQ level from 21 to 50

About 2% of people on Earth have an intellectual development level of 21 to 50 points, they suffer from dementia, an average degree of mental retardation. Such people cannot learn, but are able to take care of themselves, but most often have guardians.

IQ level up to 20

People with a severe form of mental retardation are not amenable to training and education, they have an intellectual development level of up to 20 points. They are under the care of other people, because they cannot take care of themselves, and live in their own world. There are 0.2% of such people in the world.
