Average IQ. What is the highest IQ in the world? How and when did the test appear?

Good day, dear readers! Each of us is unique, knows a lot and knows a lot. Scientists have decided that what we can do is easy to measure. This is how the term came into being, known to us firsthand as IQ.

Someone boasts about the number obtained as a result of testing and compares it with the scores of famous personalities. Someone is familiar with this abbreviation only from afar and has no idea what an IQ test is and what it consists of.

And really, who suddenly decided that we can be compared with each other in intelligence using some points? How many of them do you need to be “ahead of the rest” and, in general, is it possible to measure the brain?

Lesson plan:

How and who began to measure intelligence?

They tried to measure human intelligence back in the 30s of the last century, and for this, scientists carried out all sorts of experiments! The pattern between nerves and the body's reaction was sought, the dependence of the mind on the size of the brain was calculated, the mental abilities of parents and children were compared, and the influence of social origin and the number of years on intelligence was determined.

Wilhelm Stern from Germany in 1912 first mentioned the concept of “Intelligence Quotient” as a quantitative assessment of mental development. In his calculations, it was the quotient of mental age divided by the chronological number of years. If everything is clear to everyone about chronological age, then I’ll explain what mental age means.

As early as 1905, there was a series of tests for children called the Binet-Simon scale, which provided items for ages 3-13, suggesting that intellectual development occurs through biological maturation independent of academics. Based on the success of the tests performed, the scale determined the same mental age.

Later, the set of tests was improved, the age limits were expanded to 18 years, and a statistical norm was used for comparison. But most importantly, the German scientist Stern assured everyone that the minds of children at different ages cannot be the same, and therefore he began to look for that same quotient, multiplying the number obtained from dividing the two ages by a hundred.

The result of this mathematical calculation is nothing other than modern IQ. And tasks in tests for children began to be grouped by difficulty in accordance with the number of years.

Today, quantitative assessment of a person's intelligence in comparison with the average person of the same age has become especially popular. Many well-known companies use it when they recruit employees. There are tests for children, helping teachers determine the abilities of students.

Although the IQ test is not an exam, it essentially reveals ingenuity and erudition, which are directly associated with intelligence and thereby determine whether the applicant can cope with the tasks assigned to him.

How do IQ tests work?

Today there are no uniform standards for IQ tests. At first, these tasks to determine the level of intelligence included only lexical exercises, but today you can find tasks on non-arithmetic counting, meet logical series, they offer to complement geometric figures, ask you to identify fragments and remember some facts, as well as manipulate words.

They can consist of a different number of questions, the answers to which must be given within a certain time.

Each test contains tasks of increasing complexity and requires a quick, creative approach and innovative thinking. Moreover, they should be separated by age. This explains that a first-grader and a university graduate can have exactly the same IQ test results.

The average number of points for an ordinary inhabitant of the planet is 100 units. Half of the solved tasks correspond to this indicator. Accordingly, the maximum that can be scored is 200.

Interestingly, tests can not only evaluate your intelligence, but also show your predisposition to the image. And a low level, for example, in logic or verbal perception, does not mean at all that you are a complete layman. As scientists say, this is just your weak point and a large reserve, a gap in which you need to train.

There are several tests to determine IQ. I will give examples of the most famous ones.

Wexler's assignments

They diagnose general intelligence in terms of verbal and nonverbal mental development. Each group has 10-30 questions. Verbal ones include general concepts, searching for similarities, and numerical series. In non-verbal ones - encryption, searching for missing elements, sequence, folding figures.

Often these tests are used to determine neuropsychiatric pathologies.

Amthauer testing

It is intended primarily for professional psychodiagnostics, determining the volitional and emotional qualities, interests and needs of an audience aged 12 and older, but is more often used for the age category of 35-40 years. Involves verbal, mathematical, spatial and mnemonic (related to memorization and reproduction) tasks.

The method consists of 9 sections, each with 16-20 timed tasks. At the same time, they even provide examples of an algorithm of actions that will need to be used to decide. The test results will be profiles, for example, type M - humanities, type U - technicians, and so on.

Raven's Progressive Matrices Test

It represents a whole battery of tasks for analyzing the level of intelligence through visual thinking and analogy for different ages and education, nationality and gender. In it you need to organize sequences of geometric shapes, which become more complex over and over again, revealing patterns.

This technique is considered one of the purest forms of measuring general intelligence.

Method of English psychologist Hans Eysenck

This is the most popular IQ test. It is by this method that today ordinary people between the ages of 18 and 50 with at least a secondary education determine the very coveted points that those skilled in completing tasks can boast of.

There are eight of its options in total, all of them are intended for a general assessment of the level of mental development. The first five are tasks on general skills, the next three assess verbal, mathematical and visual abilities. At the same time, both verbal and arithmetic tasks are given equally, therefore both technicians and humanities students are placed in equal conditions.

How to read IQ results?

Based on the results of Eysenck testing, you can classify yourself as one of the smart groups. I can’t say with exact certainty that this is true, since Eysenck’s tests are often criticized, but the statistics of scientists record several levels.

• So, the standards, which is 50% of the planet's inhabitants, receive their average 90-110 points. This is enough to pass exams and enter universities, subsequently working as middle managers.
• There are those who have an IQ value above the average:

111-120 makes it possible to study at higher educational institutions without stress, and if you have the proper hard work, get a good job after studying, about 12% of them,

121-130 - a good opportunity to succeed in leadership and creativity, there are about 6% of them,

131-140 is already an extremely high figure, such people are no more than 3%, they are successful in specific fields, they can be scientists and engage in research work,

those whose indicators exceed 140 not only develop themselves, they move science and knowledge forward. By the way, there are only 0.2% of them.

• There are those whose IQ values ​​do not reach the required average level:

81-90 points allow you to get a secondary education and get a good job in places where physical rather than intellectual labor is required, this is about 10% of the population,

71-80 make it possible to cope with primary school and college, this is also 10% of all of us combined

51-70 points are received by those who, with effort, are able to receive a special education, but with such IQ indicators they are already beginning to talk about mental retardation, such people are about 7%,

Below 50 are people who are unable to study or suffer from some kind of mental illness.

I offer it to you for free take the IQ test online here and find out your prospects. However, don’t get hung up on these numbers! As recent criticisms from many science professors have argued, these tests should not be blindly trusted. After all, this is just a predisposition to a certain type of task, which you can train to solve, and also half a lottery.

Good luck to you, and whoever is braver, post the results. It would be interesting!

Well, whoever is more agile, join in to our VKontakte group so as not to miss anything important, interesting and fun)

IQ tests do not lose their relevance, therefore they continue to be used quite widely in a variety of circles. Often such tests are carried out in schools and higher educational institutions to determine the student's coefficient. Also, an IQ test may well be carried out during a job interview, especially if it concerns some leading company or organization that needs people with a sharp mind and the ability to quickly make the right decisions. And in order to be prepared for this, you need to understand what kind of IQ a person should have.

What is a person's normal IQ?

The first thing that needs to be understood is that during the test, not only the results of the test must be taken into account, but also the age of the subject, since at different ages different indicators can be considered the norm. The result, which will be quite normal for a ten-year-old child, at twenty years of age will already become a rather significant deviation from the norm, not for the better. Therefore, the average IQ of a person is very relative and depends on the age factor.

Speaking approximately, we can derive very generalized values ​​of what a person’s IQ level should be. In general, the scale of results starts from 70 and ends at 180. If the scores are less than 70, then this is considered mental retardation. Approximately 25% of the population has scores between 70 and 90, and these are school graduates without high school and low-skilled workers. A score from 90 to 110 is considered average; about half of the population has it - high school students, office workers, and so on. Indicators above 110 are already gifted, intelligent people, capable of quickly making extraordinary decisions. Usually there are indicators within 150, and higher - this is still quite a rare occurrence.

Result 110. I did the exercise with a piece of paper to write down numbers. Duration of sleep this night is 4 hours. Conclusion, if you get a good night's sleep and write down intermediate results on a sheet, you can easily achieve 120-130 points.

The main thing is not to blame the complexity of the test and the suboptimal state of mental abilities. Then people will respect you.

Many of us have heard the expression “human IQ.” This term sounds when we are talking about the abilities of an individual, his mental development. The concept of “IQ” is the intelligence quotient. It is an assessment of the level of ability in comparison with the average intelligence of a person of the same age as the subject. To determine the level, you must pass a special test for logic, flexibility of thinking, the ability to quickly count and identify patterns.

A little history

The concept of “intelligence quotient IQ” was first formulated in 1912 by Wilhelm Stern. This is a very famous psychologist and philosopher. He proposed using the result of dividing actual age by intellectual age as the main indicator of the level of development. After him, in 1916, this concept was used in the Stanford-Benet intelligence scale.

Gradually, people began to take an active interest in their level of intelligence, so a huge number of various tests and scales were invented that made it possible to find out its coefficient. The creation of numerous tests led to the fact that many of them were unreliable, so it is quite difficult to compare the results of different tests.

How to determine the level of intelligence? Today, in many schools, children are tested to find out their level of intelligence. The development of the Internet has contributed to the fact that people, including adults, can easily get tested online.

How to find out your IQ

To determine the IQ value, special tests were developed. There are two types:

• for children 10-12 years old;
• for children over 12 years old and adults.

The measurement technique is the same for all options, only the level of difficulty of the questions changes. Each test has a certain number of questions and a limited time to complete them.

They are designed so that the results, which are described by a probability distribution, show an average IQ of 100. The values ​​are grouped according to the following scheme:

• the coefficient of 50% of all people is in the range of 90-110;
• the remaining 50% of people are divided equally between those with a score below 90 and those with a score above 110.

What IQ level corresponds to mild mental retardation? If its indicator is below 70.

The tasks in the tests are varied, the complexity of each subsequent task increases. There are problems for logical and spatial thinking, knowledge of mathematics, attentiveness, and the ability to find a pattern. Naturally, the more correct answers a person gives, the higher the assessment of his level of intelligence will be.

The tests are designed for different age groups, so the indicators of a teacher and a 12-year-old student can be the same, because the development of each of them will correspond to his age.

Today on the Internet you can find a huge number of different tests that offer to find out your level of knowledge and intelligence. But most of them were not developed by professionals, so they are unlikely to show reliable results.

To find out your level of intelligence you need to use professional tests, such as:

• Kettler;
• Amthauer;
• Eysenck;
• Ravena;
• Wexler.

Main influencing factors

The human mind is quite difficult to define and measure. Intelligence is a combination of knowledge, skills and abilities that accumulate throughout a person's life. Our intelligence is based on several important factors that influence its coefficient:

• genetics;
• feeding habits of a child in the first years of life;
• education and mental stimulation of the child’s mental activity by parents;
• order of birth of children in the family;
• environment.

All this, to one degree or another, affects the mental development of the child.

Genetics

Scientists have long begun to explore the question of how much the level of intelligence IQ depends on genes. For more than a century, studies have been conducted on the influence of genes on mental abilities, which have shown that the percentage of dependence is in the range of 40-80%.

The level of intelligence in a person depends on the structure of the brain and its functionality. These two factors are key. Differences in the parietal-frontal parts of the brain of different people indicate different levels of their IQ. The higher the level of functionality of the frontal areas of the brain, the better it can work: perceive and remember information, solve various problems.

Genetic factors represent the potential that is passed on from parents to the child. They are little studied, but have an important function for the development of mental abilities.

Chromosomal abnormalities that are inherited also affect the level of intelligence. For example, Down's disease, which is characterized by poor mental development of the child. Quite often it occurs in children whose parents belong to the older age group.

Illnesses during pregnancy also affect the baby's mind. For example, rubella, which an expectant mother suffers from, can lead to negative consequences for the baby: loss of hearing, vision, low level of intelligence.

Influence of nutrition

The level of intelligence depends on what exactly we eat in the first years of life, and what the expectant mother ate during pregnancy and breastfeeding. Proper and nutritious nutrition has a positive effect on brain development. The more nutrients, vitamins and microelements the child consumes through the mother and the next few years after birth, the larger the size of the cerebral velum will be. It is responsible for learning and memory.

Consumption of large amounts of fatty acids has a positive effect. Scientists have conducted studies that have proven that if a woman consumes a lot of fatty acids during pregnancy, then children will be significantly ahead of others in their development.

Upbringing

Education is one of the key factors in the development of mental abilities. Even if a person is by nature genetically predisposed to a high IQ level, due to the lack of proper upbringing and quality education, the coefficient will not be higher than average.

Education includes many factors:

• family lifestyle;
• home conditions;
• the level of education;
• parents' attitude.

To study the influence of upbringing, academics separated twins and placed them in different environments. After all, if intelligence is a biological concept, then in theory it should be the same in twins, regardless of living conditions. This is wrong. Studies have shown that children who live in orphanages have lower intelligence levels. Also, the indicator depends on how the parents treat the child: whether they take him to additional clubs, force him to study music, drawing, or instill a love for logic games.

Family birth order

This issue has been studied for a long time, but scientists have not been able to come to a common conclusion regarding the influence of the order of birth of a child and the number of children in the family on their mental abilities. Many studies have shown that first-born children are more mentally developed than other children. In history, most astronauts, presidents, scientists and famous political figures were firstborn.

Many people are interested in the question of why this happens. Birth order is not a judgment. The biggest impact is that a family with one child can devote more time, attention and resources to learning. Testing has shown that first-born children are only 3 points ahead of other children.

Environment

Whether we can use all the capabilities of our brain depends only on us: on our lifestyle, the presence of bad habits. Various diets and toxins affect the development of intelligence throughout life.

If the expectant mother smokes, drinks, or uses drugs, the child is unlikely to be healthy. A person’s mental performance may deteriorate if he drinks or poisons his own body.

Scientists have found that the level of intelligence of people from different countries differs significantly. Some tests have shown the dependence of average IQ on the country's GDP, crime, birth rate, and religion.

Some interesting facts about IQ:

• the higher the coefficient, the more sociable the person;
• breastfeeding increases the score by 3-8 points;
• during the summer holidays the indicator decreases;
• a score above 115 guarantees that a person can cope with any job;
• people with scores below 90 are more likely to become antisocial, end up in prison, or live in poverty;
• the lower the IQ, the more difficult it is for a person to cope with stress;
• The higher the score, the more confident the person is.

IQ values

The highest level of intelligence is achieved by mathematician Terence Tao from Australia. He has a coefficient above 200 points. This is very rare, because most people barely reach 100. Almost all Nobel Prize winners have a high IQ - above 150 points. It is these people who help technology develop, actively participate in research, make various discoveries, study space and physical phenomena.

Notable people include Kim Peake, who can read a page of a book in just a few seconds, Daniel Tammet, who can memorize an incredible number of numbers, and Kim Ung-Yong. He entered and successfully began his studies at the university at the age of 3.

Let's look at all possible intelligence indicators of IQ tests:

1. Above 140. These are people with incredible intelligence and rare creative abilities. They can easily achieve success in scientific activities. Bill Gates and Stephen Hawking can boast of this indicator. People with high IQs make the greatest discoveries and are geniuses of their era. They are the ones who explore space, create new technologies, search for cures for diseases, study human nature and the world around us. The percentage of such individuals is only 0.2 of the Earth's population.
2. Indicator 131-140. 3% of the world's population can boast of this level. They include Arnold Schwarzenegger and Nicole Kidman. Successful people who achieve their goals have a high level of intelligence. They can become successful politicians, managers, company leaders, and specialists in science.
3. Indicator 121-130. High level intelligence. People with this indicator find it easy to study at a university. They make up 6% of the population. They are successful, often become leaders, and are actively involved in creativity.
4. Indicator 111-120. Above average intelligence level. Occurs in 12% of the population. They love to study, they have no problems with science. If a person loves and wants to work, then he can easily get a well-paid job.
5. Indicator 101-110. Most people on the planet have this level of intelligence. This is the average IQ, which indicates the usefulness of a person. Many of its holders have difficulty graduating from university, but with enough effort they can study and get a good job.
6. Indicator 91-100. The result for a quarter of the world's population. If the test shows such a result, do not despair or be upset. Such people study well and can work in any field that does not require significant mental effort.
7. Indicator 81-90. The coefficient is below average. Occurs in 10% of people. They do quite well at school, but rarely receive higher education. They often work where they do not need to make mental efforts; they prefer to work physically.
8. Indicator 71-80. Approximately 10% of the population with this level of intelligence. Occurs in people who suffer from mild mental retardation. They often study in specialized schools, but can also study in normal secondary educational institutions. Only their successes rarely rise above average.
9. Indicator 51-70. Occurs in 7% of the population who have a mild form of mental retardation. They are rarely full members of society, but they are quite capable of living independently and taking care of themselves without outside help.
10. The indicator is 21-50. Very low level of intelligence, which occurs in 2% of people. Individuals suffer from dementia and are far behind their peers in development. They cannot study normally and have guardians who help them take care of themselves.
11. Below 20. Such people make up no more than 0.2% of the population. This is an indicator of severe mental retardation. Such people cannot live on their own, go to work, earn their own food, clothing and accommodation, so they are constantly under guardianship. They cannot learn and often suffer from psychological disorders.

The result should not be taken as a single truthful authority. After all, the indicator depends on many factors: environment, heredity, lifestyle, place of residence, religion.
