What is the average iq score of a person. IQ

Many of us have heard of the IQ test, which measures a person's level of intelligence. However, most people know almost nothing about it. Before you start taking the test, you must definitely find out what the IQ of a normal person should be.

general information

The abbreviation IQ stands for intelligence quotient, which can be translated as "amount of intelligence." In the Russian-speaking language environment, the well-established expression "intelligence quotient" is more often used. However, it is believed that in order for the results to be as truthful as possible, and they can really be trusted, it is worth taking into account not only the results of the test itself. Factors such as age and gender also need to be taken into account.

Many also believe that the results of this test indicate a person's aptitude for a particular type of task rather than actual intellectual ability. Therefore, you can prepare for it by solving puzzles that resemble those presented in the tasks.

Story

Attempts to study the IQ of a normal person began in the 30s of the last century. Researchers have made a number of attempts to determine the IQ through various experiments. Scientists tried to find a pattern that would link the processes of the central nervous system, response characteristics and mental abilities, even taking into account the size and weight of the brain. In addition, they studied the relationship between the IQ of parents and children, its relation to social origin, age, and so on.

IQ test today

It is now generally accepted that the coefficient of mental intelligence depends on many factors, for the most part on heredity. However, the IQ level of a normal person can be increased by solving various problems and tests. Besides, in modern world it is not so much intelligence that is the source of success as motivation and perseverance. Individuality, determination and ambition also play an important role. Nevertheless, it is a high level of intelligence that can help in solving difficult life circumstances and contribute to more advantageous conditions.

Despite the fact that the first tests were created exclusively with lexical exercises, today they use a wide variety of tasks. Among which are counting exercises, logical series, the ability to find the missing geometric figure, the ability to recognize a fragment, remember facts, technical drawings and determine the missing letter.

How much IQ does a normal person have

The average level of human intelligence ranges from 100 to 120 units, which is about half of correctly solved problems. The person who completes all the tasks receives 200 points. In addition to the level of intelligence, the test determines other indicators, it helps to identify the way of thinking of the person who passes it. By identifying the category in which the test subject has the lowest level of ability, one can help him identify gaps in his ability, practice different types of tasks, and raise his IQ.

First tests

For the first time, V. Stern spoke about the IQ, who considered the definition of the level of skills on the Binet scale to be incorrect, since he had a serious drawback regarding age. The scientist proposed to determine a person's abilities by dividing mental age by chronological age. The IQ test of a normal person demonstrates a quantitative assessment of the ability of an individual in relation to the average representative of the same age.

Averages

It is rightfully considered that an IQ test does not show the level of a person's erudition, but only an assessment of general indicators. They are designed specifically to get a distribution of results with an average score. The IQ of a normal person can vary, but there are common indicators. So, about half of the people who passed the test show a result equal to 90 to 100 points, a quarter - below 90, and the other quarter - above 110 units. The average score for graduates from American universities is 115 points, for honors students - from 135 to 140. An IQ level that is less than 70 points is usually considered a sign of mental retardation.

Conclusion

IQ tests show the level of development of a person's abilities, but should not be considered that they in any way indicate the level of erudition. They only help to understand in what area and in what direction a person needs to develop.

It is believed that the IQ level of a normal person varies from 90 to 120 conventional units. Most often, the Eysenck test is used to determine the IQ. However, do not forget that the most correct results will be obtained during the very first passing of the test, and all subsequent attempts will only distort them.

Human IQ is a measurable assessment of human intelligence, expressed in points. The IQ varies from person to person, so it’s worth figuring out what level can be considered normal.

Age

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. 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 based on IQ tests.

And then they

pass

training on the strengthened 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.

Race

Strange as it may sound, but IQ varies from race to race. For example, the median IQ for African Americans is 86, for whites of European descent it is 103, and for Jews it is 113. All this speaks in favor of the supporters of scientific racism. However, this gap is narrowing from year to year.

Floor

Women and men do not differ from each other in intelligence, but, according to statistics, the IQ between them differs depending on age. Boys under the age of 5 years are somewhat smarter than their peers, but, starting from the age of 10-12 years, girls are ahead of boys in development. This gap disappears by the age of 18-20.

Normal IQ

The IQ of an adult depends on many factors - genetics, upbringing, environment, race, etc. Although the average IQ is about 100 points, it varies from 80 points to 180. This IQ limit is laid down in the classic IQ test, developed by the English psychologist Hans Eysenck in 1994. In order to obtain adequate data on this test, it must be passed once in a lifetime in adulthood. Repeated passage distorts and overestimates the results.

If the IQ is below 80 points, then this indicates the physical and mental deviations of a person. If IQ exceeds 180 points, then this indicates the genius of the owner of such points. But these dependencies are very conditional. For example, the great physicist Albert Einstein was the most backward in the class in terms of academic performance, which did not prevent him from developing the theory of relativity in the future. And on the other hand, according to the Guinness Book of Records, the largest IQ of 228 points was recorded in 1989 by ten-year-old American Marilyn Waugh Sawan. This is where her personal achievements end.

IQ - intelligence quotient, which is mainly determined by heredity. But it can still be changed for the better. To do this, you need to do some exercises, and soon you will not know your IQ!

There are no specific age limits for the development of human intellectual abilities. Modern publishing houses produce a lot of books necessary for the development of the IQ level.

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

What iq level is considered normal

An IQ test can be used for many reasons. It allows you to determine your level of ability to learn, understand, form concepts, use information, apply logic and reason, in comparison with the population. It speaks volumes and can affect the characters that are not the norm in society, whether they are interpersonal, such as isolation, rejection and withdrawal, or intellectual, such as ease or difficulty in performing intellectual activities. On the other hand, it can also explain the successes achieved by individuals in a simpler way than by other people.

The effectiveness of this test

The IQ test offered by us was developed by a research group of specialists in the field of psychology. It is used worldwide by millions of users and new ones are added every day. The statistics established on the basis of the overall results allow to test its reliability in relation to the IQ scales represented by the Gaussian curve.

over gifted

People with very high IQ levels, compared to average (> 130), also called "super gifted", tend to have more opportunities for intellectual activity than others. The most well-known characteristics of the super-gifted are:

• Curiosity and thirst for knowledge: They ask a lot of questions and are able to acquire knowledge on their own.
• Self-improvement, the need to do something with precision and perfection.
• Fear of himself, of his abilities, the consequences of his thoughts and emotions overflowing.
• An interest that becomes obsessive in certain topics.
• Hypersensitivity is often invisible from the outside.
• Prolonged concentration and focus.
• Metacognitive Awareness: They are able to identify and use plans, concepts, and strategies to solve problems.

People with very low IQs

Our statistics

We accompany each IQ result with individual statistics, according to which candidates rank based on several parameters (population, age, education level, area of ​​expertise).

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 an extremely high IQ (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?

The level of IQ is 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's Everyday life were 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 contribute incredibly high contribution in 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 the famous people who have a similar test result are 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. Individuals with this score tend to attend special schools, but may also graduate from regular elementary school with average grades.

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.

IQ tests do not lose their relevance, therefore, they continue to be widely used in a wide variety of circles. Quite often, such tests are carried out in schools and higher educational institutions to determine the student rate. 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 make the right decisions quickly. And in order to be ready for this, it is necessary to understand what kind of aikyu a person should have.

What is the norm of aikyu in a person?

The first thing to understand is that during the test, not only the results of passing the test should be taken into account, but also the age of the subject, since different indicators can be considered the norm at different ages. The result, which will be quite normal for a child of ten years old, at twenty years old will already become a rather significant deviation from the norm, not for the best. Therefore, the indicators of the average aikyu of a person are very relative and depend on the age factor.

Speaking approximately, it is possible to derive very generalized values ​​of what a person's aikyu 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 results from 70 to 90 and these are school graduates without senior classes, workers with low qualifications. The average is considered to be a result from 90 to 110, it is possessed by about half of the population - these are high school students, office workers, and so on. Indicators above 110 are already gifted, smart people, able to quickly make extraordinary decisions. Usually there are indicators within 150, and above - this is still quite a rare occurrence.

The concept of "intelligence quotient" and the abbreviation IQ are familiar to almost everyone today. And everyone is aware that this very coefficient can be assessed using special tests. But this is where the knowledge of many people who are far from psychology and related sciences ends.

So what is IQ, how is it measured, and should it be done at all?

Let's start with a little historical digression. At the beginning of the 20th century in France, the state instructed a psychologist Alfred Binet tests to determine the mental abilities of children. To this end, Binet developed a test, which is known today as " IQ Test»

The test very quickly became popular, but not in France, but in the USA. As early as 1917, the US military began using IQ tests to classify soldiers. More than 2 million people passed this exam. Then IQ tests began to be used by universities and private companies, which used them to screen applicants and potential employees.

The results of numerous studies have allowed foreign experts to make the following generalizations:

You have exactly 30 minutes to complete the test. The most reliable and reliable results, indicating the abilities of a person, are obtained in the range from 100 to 130 points, outside these limits, the assessment of the results is not sufficiently reliable.

In conclusion, it should be said that, according to a number of psychologists, tests developed in the West for determining the IQ are not entirely suitable for Russia. The main reason is the difference in the structure of the intelligence of different countries. The Russians are dominated by the so-called "figurative" style of thinking, that is, the Russian more often "thinks" with his heart, and not with his head. It remains only to wait for ours to offer their own methods for assessing intelligence. While they are not...
