IQ test results for famous people

IQ tests are almost never used in Russia. But the term itself has become widely known.

Most people know that IQ (read “IQ”) is an indicator that reflects the strength of human intelligence. But what does it mean and how is it calculated?

It all started with the French psychologist Alfred Binet in 1905. He worked with mentally retarded youth and, together with his colleague Theodore Simon, developed a method for measuring psychological age young people, which in the case of their charges differed from biological age.

Then in 1912, German psychologist William Stern developed a method for determining the ratio of intellectual to biological age. He found that this ratio remained virtually unchanged as children grew older.

This ratio became known as the “Intelligence Quotient” or IQ. It is calculated by the formula:

100 x (intellectual age/biological age).

So, if you are 30 years old, but have the intelligence of 25 years old, your IQ would be: 100 x 25/30 = 83.

Distribution of IQ among the population (on the vertical axis - % of the population with iq indicated on the horizontal axis

It is clear that using this method, the average IQ for the entire population will be 100. A person’s individual IQ demonstrates how much higher or lower a person is than the average intellectual level of his age.

Thus, to conduct tests, statistics on the execution of these tests are first collected on large quantities Human. Each newly tested person's performance is then compared to the average performance of people previously tested.

Since in the classic version of tests the results are compared with an audience of the same age as the test subject, IQ also indicates the rate of development of intelligence.

Intelligence tests are designed to test all areas of your brain: calculations, pattern recognition, continuation, logic, word processing, abstraction, etc. The obtained result is compared with the norm.

There are different interpretations of the results obtained.

80% of the population has an IQ in the range of 80–120.

There are quite a few communities of people with high IQs in the world. For example, Mensa, which has members from more than 100 countries, requires an IQ of at least 132 for its members.

In order to get into the Olympic community (Olympiq Society) you need an IQ of 180. The community website states that it has only 14 members.

Scores on IQ tests are believed to be a good measure of people's ability and to be a good predictor of their performance prospects. hard work. Most professors have an IQ of one hundred and thirty, which places them in the top 3% of the population in terms of intellectual ability.

Although IQ tests are not infallible, their results are a useful indicator. Typically, IQ remains the same throughout life.

Interestingly, a study conducted in Scotland in the 1950s and 1960s, involving more than 11,000 people, showed a relationship between IQ scores and morbidity and life expectancy.

A pattern has been revealed that a person with a lower IQ has, on average, a lower life expectancy than a person with a higher IQ.

A lower IQ means a higher chance of developing Alzheimer's disease and other forms of dementia.

What was Einstein's iq?

Albert Einstein never took a test to change his IQ level. Of course, there is no doubt that the famous physicist would be able to show high results. Most likely he would be in the region of 200, that is, on par with the very best celebrity achievements.

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 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 over in a simple way than other people.

The effectiveness of this test

The IQ test we offer 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. Statistical data established on the basis of the overall results make it possible to verify its reliability in relation to IQ scales represented by the Gaussian curve.

Super gifted

People with very high levels IQs above average (>130), also called “super-talented,” tend to have more intellectual potential 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 excellence.
• Fear of himself, of his capabilities, the consequences of overwhelming thoughts and emotions.
• An interest that becomes obsessive in certain topics.
• Hypersensitivity is often invisible from the outside.
• Prolonged concentration and concentration.
• Metacognitive Awareness: They are able to identify and use plans, concepts, and strategies to solve problems.

Our statistics

We accompany each IQ result with individual statistics that rank candidates based on several parameters (population, age, education level, field of study).

Intelligence quotient (IQ) is a comparative assessment of the level of development of the person being surveyed. Otherwise, this is the level of intelligence in relation to the level of development of the average person of the same age. Typically, intelligence quotient (IQ) is determined by a psychologist based on special tests. Most IQ tests are designed to assess a person's ability to logically solve problems. You should not be mistaken and consider the IQ test as a test to determine the level of knowledge (erudition). IQ is just an attempt by psychologists to estimate the factor of general intelligence.

The test consists of 50 questions and lasts 40 minutes. With us you can take an IQ test (intelligence test) for free (no SMS and no registration)!

When taking the test, you cannot use paper, a calculator, a pen, a cheat sheet, the Internet, or tips from a friend. After answering a question, answering it again is not possible. After the time has expired, the test will automatically end. IQ tests are designed so that the results are characterized by a normal distribution with a mean IQ of 100 and such a spread that 50% of people have an IQ between 90 and 110 and 25% each have an IQ below 90 and above 110. The average IQ of university graduates is 115, excellent students - 135-140. An IQ value of less than 70 is often classified as mental retardation.

IN scientific world shock: a three-year-old American from Tennessee, Selena Janik, had an intellectual IQ of as much as 135 points - more than US President Barack Obama and British Prime Minister David Cameron.

It turns out that the little girl is smarter than them and most adults? The same IQ for scientists averages about 125 points, and for ordinary office clerks 100 - 105 points. This begs the question: does IQ lie? And in general, is it possible to objectively measure intelligence and reliably find out who is smarter? An RG correspondent talks about this with Victoria Yurkevich, a professor at the Moscow City Psychological and Pedagogical University.

Victoria Solomonovna, can we compare the intellect of two people, as if we were comparing them? physical strength in tug of war or arm wrestling?

Victoria Yurkevich: There is no instrument for measuring intelligence or talent in nature. Even if you give people the same intelligence tests, comparing their results will be incorrect. Everyone's brain works differently; it is focused more on one or another area of ​​activity.

How to find out who is smarter: a famous physicist or a legendary violinist? Each is great and incomparable in his field. But there are no uniform criteria by which their mental development could be compared.

What about the IQ test?

Victoria Yurkevich: It reveals only intellectual abilities in the sphere of general intelligence, that is, the ability to draw logical conclusions and structure information. It is known that theoretical physicists usually have the highest IQ scores. They constantly calculate the most complex speculative models, this type of thinking is fine-tuned, and these tests are easier for them to cope with. But, let’s say, artists usually don’t score comparable points. But can we really say that Aivazovsky is stupider than Landau? Of course not. They just different types intelligence. An artistically gifted person usually performs significantly worse on IQ tests than mathematicians or technicians. But no conclusion can be drawn from this.

What to do with a young American woman who, at the age of three, outshines respectable adult men?

Victoria Yurkevich: IQ is the ratio of a person's mental maturity to his biological age. Initially, it was invented to select school students who are able to master the program. Then the researchers, with the help of child psychologists and teachers, formed a set of knowledge and skills that a child should have at a certain age. If you can do everything that is required at your age and nothing more, your IQ is exactly 100. A hundred is the norm. If you master something additional, keep your 105, 120 or even 140 points. If you didn’t have time or couldn’t learn something in time, you’ll get 95, 92, 87 points. And so on.

By the way, an IQ less than 90 is already a sign of developmental delay. If we return to the girl and Obama, then the comparison itself is incorrect. It is possible that the girl can do things that her peers have no idea about. Compared to other three-year-olds, she is precocious. But if you compare her with any adult, and especially with such an intellectual as the current President of the United States, she will still be just a small child. Their IQ scores are measured on different scales. These are incomparable quantities.

If the IQ index does not provide an opportunity to compare the strength of intelligence, why is it so popular, including among psychologists?

Victoria Yurkevich: Here the situation is much more complicated. There are six main types of intelligence. Firstly, intellectual or logical is the ability to understand, comprehend and compare. The second is academic, it implies a good assimilation of ready-made knowledge. Social - its owners easily understand the mood and interests of people and can carry them along with them. There is also artistic intelligence, which implies the ability to operate with images, create them, understand other people’s metaphors and allegories, practical - such people are usually said to have “golden hands”, they can assemble, make, repair or construct anything, and, finally, sensorimotor is the ability to control your body. Every person has all types of intelligence. But some will be dominant, others will be expressed, and somewhere there may be failures. Precisely because the physicist and the artist work different types intelligence, it is very difficult to compare them with each other. Here's a mathematician and, let's say, a biologist, no matter what, they have a mentality that is at least approximately similar.

But whatever a person’s talent, he will not be able to realize it without logical intelligence. The artist will not appreciate the beauty of the landscape or the model, the actor will not understand the director's intention and will not figure out how to play this or that scene. The athlete will not calculate his strength and will collapse from fatigue in the middle of the distance.

The IQ index measures logical intelligence. For those who succeed in science, its value will most likely be, relatively speaking, more than 130 points. For an actor or athlete to succeed in their profession, a more modest level of 110 points will be enough. This does not indicate that they are less intelligent, it is just that their talent is revealed through other mechanisms that cannot be taken into account in this test. But when IQ is less than 90 points, we can talk about mental retardation. With such intelligence it is extremely difficult to succeed in anything. Although there are exceptions.

It turns out that the IQ index doesn’t really mean anything. Why then do they continue to use it?

Victoria Yurkevich: The IQ index itself does not allow us to say who is smart and who is stupid. But at school it is very useful for identifying mentally gifted children. Those who have been given this or that type of talent need a different type of training, other forms of pedagogical and psychological support, otherwise their high abilities will not develop, and, most importantly, they will not be able to be realized in the future. How does it usually work out? A gifted child comes to school. During the first few years he gets his A's without stress and relaxes. In order to develop intellectual and strong-willed qualities, the student definitely needs a challenge; he must be faced with difficult and interesting tasks. There are no such? It's gone. After such training, nine out of ten promising boys and girls remain only traces of their former talent.

Our university conducted very extensive monitoring of giftedness. 63 schools, thousands of children, hundreds of teachers took part. It turned out that, firstly, there are intellectually gifted children in almost every school, and secondly, a significant part of teachers do not distinguish intellectually gifted children from well-educated ones. And they do not help the development of intellectual talents.

As a result, we are losing people who in the future could make up innovative resource society. But that's not even the main thing. An unfulfilled former gifted child, who, according to the well-known expression, “has his entire future in the past,” is always an unhappy person. Ambitions have not gone away, but opportunities have already been missed.

Now there are the most different ways identifying a person's talent. The IQ test is one of the most technologically advanced. You can quickly and without special costs examine many people at once. But the results of these tests must be treated very carefully.

What is the danger?

Victoria Yurkevich: There is a norm, there is a lower limit of the norm, and there is the top five percent of results - these are the most gifted students. We measure things a little differently, but, for information, an IQ of 127 and above indicates a child’s serious abilities; more than 140 is already outstanding talent. But only high results can be taken seriously. That is, if a student has done work on high scores, this directly testifies to his talent. And if the result turns out to be very mediocre or even frighteningly low, say 80-90 points, then sometimes it doesn’t mean anything at all. The child could feel bad, be upset about something, be nervous - there are a whole lot of reasons why on this particular day he coped poorly with this particular task. Only after special diagnostics can specialists name the real reason such results.

When selecting an applicant for a vacancy, specialists conduct a whole battery of tests to understand whether this person is suitable for a particular job or not. They look at him from different angles, check all aspects and types of intelligence, his interests and motivation, and only after that they make a decision. And although no one can give an absolute guarantee, in the overwhelming majority of cases their recommendations are justified.

Even when selecting gifted students, an IQ test is just one of a series of indicators. The child’s interests, his motivation, school and extracurricular achievements - only all this together can show a professional the true level of a particular child.

too smart

It remains to be seen who poses the biggest problem for school teacher: poor student or gifted child. It would seem that if a student easily and naturally gets straight A's from the first grade, this is very good. However, there is a great danger here.

If it is too easy for a student to learn, and he does not encounter difficulties and easily completes all the teacher’s tasks, this is extremely bad for his development, warns Victoria Yurkevich. - The child gets used to grasping everything on the fly and not straining. Why, if he is quite successful even if he is relaxed? As a result, neither the child’s abilities nor his personality develop to the required extent.

Such a student will quickly drop from “A” to “C”, he will not develop his abilities, and studying will turn into hard labor for him. To prevent this from happening, the most talented students are now being identified from the very first days of school. As the best cure for boredom in class, they are given more difficult tasks and forced to honestly earn their A's.

We always believe that every gifted child will achieve a lot in the future,” continues Professor Yurkevich. - But for this, in addition to abilities, he will also need many other qualities: self-discipline, ability to set main and intermediate goals for himself. This is very easy to learn in school age. After that it’s already difficult. Gifted children who click easily school curriculum, these skills are deprived. And as a result, their talent turns out to be unrealized. Having talent and not using it in any way is always very sad. Therefore, gifted children must be identified and nurtured.
