IQ 95 what does it mean. What is the IQ of a normal person? What determines the level of IQ

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?

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 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.

There is a lot of talk about IQ tests these days, but many people still don't know what these scores really mean. What exactly is a high IQ? And the average? How many points do you need to score to be considered a genius?

IQ, or intelligence quotient, is the score obtained on a standardized test designed to measure intelligence. It is formally considered that in the early 1900s with the introduction of the Binet-Simon test, but later it was revised, and the Stanford-Binet test acquired universality.
IQ tests have proven to be very popular not only among psychologists, but also among other specialists, but there is still a lot of controversy about what exactly IQ tests measure and how accurate they are.
In order to adequately evaluate and interpret test results, psychometricians use standardization. This process involves conducting a test with a representative sample of the population. Each participant takes the test under the same conditions as all other participants in the study group. This process allows psychometricians to establish norms or standards against which individual results can be compared.
When determining the results of the test to determine the level of intelligence development, as a rule, a normal distribution function is used - a bell-shaped curve, on which most of the results are located near or around the average score. For example, the majority of scores (about 68%) on the WAIS III test are typically between 85 and 115 (with an average of 100). The remaining results are less common, and therefore the area of the curve on which they are located is directed downward. Very few people (approximately 0.2%) score more than 145 (indicating very high IQ) or less than 55 (indicating very low IQ) on the test.
Because the median score is 100, professionals can quickly evaluate individual scores by comparing them to the median and determining where those scores fall on the normal distribution scale.

More about IQ scores

In most modern IQ tests, the average score is set at 100 with a standard deviation of 15 so that the scores follow a bell curve. This means that 68% of the results fall within one standard deviation of the mean (ie, between 85 and 115 points), and 95% fall within two standard deviations (between 70 and 130 points).
A score of 70 or less is considered low. In the past, this mark was considered an indicator of mental retardation and intellectual disability, characterized by significant cognitive impairment. Today, however, only the results of the IQ test are not used to diagnose intellectual disability. The result below 70 points is received by approximately 2.2% of people.
A score over 140 is considered a high IQ. Many believe that a result of more than 160 points can speak of a person's genius.
A high IQ is certainly closely related to academic achievement, but is it related to success in life in general? Are there really more successful people than their lower IQ counterparts? Many experts believe that other factors can also have a great influence, including.
That is, the scores are interpreted as follows.

The modern world provides a person with great opportunities for self-realization, but in return puts forward high demands on him. We must be able to adequately assess the situation and make the right choice. Scientists around the world have proven that a person's abilities are affected by his IQ level. Surely you have come across this concept more than once, and most likely even passed one or another IQ test. But let's figure out what the IQ gives us, and why we need it at all.

IQ test

So, the intelligence quotient or IQ level is a quantitative assessment of the level of intellectual abilities of a person compared to the IQ of a normal person of the same age as the subject. This indicator is determined using various tests, the most famous of which are the Eysenck, Wexler, Raven, Amthauer and Cattell tests. The very concept of "intelligence quotient" was introduced by the German Wilhelm Stern in 1912. Recently, interest in determining this indicator has increased many times, employers often ask job applicants to take an IQ test, and applicants pass it when they enter a university.

In principle, IQ test questions are structured in such a way that their complexity increases, so that the test subject must use his logical and spatial thinking. As a result of passing the test, you get a quantitative assessment of your IQ. The average IQ level of an adult according to the Eysenck test is from 91 to 110 points, 25% of the world's population has such indicators. If your IQ is between 111 and 130, you can safely consider yourself a smart person. And if your score is above 131, then you are the lucky one, who is in the 3% of the world's population. People with high IQs become outstanding scientists, inventors, and researchers. There are geniuses with an IQ above 140, such as Bill Gates and Stephen Hawking, these people make up about 0.2% of humanity.

The level of intelligence is influenced by a large number of various factors, such as, for example, heredity, genes, gender and race of a person. According to recent studies, the average IQ of an African American is 85, Hispanic 89, White European 103, Asian (China, Japan, Korea) 106, and Jewish 113. It has also been found that most men have higher IQs than women. It affects the level of intelligence and the environment in which a person grew up, as well as the education of his parents and even the country of residence.

How to know your IQ

After all of the above, most likely, you will ask yourself the question: "How to find out your IQ." Today it is very easy to do, it is enough to find one of the many tests for the level of intelligence on the Internet. However, be careful, because not all of them are licensed and may contain errors in tasks and answers. Your IQ calculated in this way may not be correct. The time-honored Eysenck test can be taken at iqtest.com in English. There is no exact answer to the question: “What should IQ be” today, so if something does not suit you, just work on increasing your level of intelligence. How? We will gladly tell you about it.

How to increase IQ

Your IQ level is a quantitative measure of mental development, which is determined using tests that measure a person's ability to solve problems, perceive various mental images, as well as memory and general knowledge. We present you several ways to increase your IQ.

Method number 1 - get into the habit of playing mind games (for example, Scrabble, Sudoku, chess, and so on). These games are great brain trainers. When you learn how to play one game well, move on - master the next, because when you master the skill, your brain stops working as hard to solve the problem, the production of the hormone dopamine, which is responsible for intelligence, decreases. In addition to intellectual board games, try your hand at logic and strategy video games. Pay special attention to games aimed at making quick decisions. It is also useful to solve logic puzzles, puzzles, crosswords and sudoku. All of these activities stimulate thought processes, increasing IQ levels.

Method number 2 - constantly learn something new, whether it be a foreign language, art, architecture or, for example, cryptology.

Method number 3 - lead an active lifestyle, constantly exposing yourself to physical activity, because this is a scientifically proven way to increase the level of intelligence. Expand your horizons, set yourself a goal for life - do not stop learning, constantly learn something new. Give yourself an occasional shake, skydive, or try bungee jumping. A new experience releases the hormone dopamine, which increases the number of neurons and causes a feeling of satisfaction. And in general, the more you know and know how, the richer your life experience, the higher the level of your intellectual development!

And here are some more simple tips that will help you enjoy life and increase your level of intellectual development.

Try to enjoy everything you do, enjoy classical music, good books and socializing with people you like.
Use electronic devices less. If you need to write something down, use a notepad and pen, and instead of an email, it's better to send a handwritten letter. This stimulates visual and kinetic perception.
Learn to write with your non-dominant hand, which stimulates the opposite hemisphere of your brain.
Try to eat right and balanced, include in your diet fresh vegetables, fruits and fish, rich in omega 3, which has a positive effect on brain function.
Get enough sleep, because only during sleep the information received passes from short-term memory to long-term memory.
Work on yourself and keep learning all your life.

Everyone is familiar with the term IQ» and the abbreviation IQ. Also, many people know that the IQ is estimated using special tests.

The founder of the development of special test programs, currently known as the "IQ Test", was the French psychologist Alfred Binet. The test very quickly gained popularity in different countries. It began to be used to determine the level of IQ not only in children, but also in military personnel. More than 2 million people have been tested. Later, the level of aikyu began to be determined by students and employees of private companies.

The IQ level allows you to determine the speed of thought processes, and not the ability of a person to think. In this regard, the use of tests today has lost its relevance.

To solve problems, you need a well-developed ability to concentrate, the ability to highlight the main thing, a developed memory, a large vocabulary and fluency in spoken language, logical thinking, the ability to manipulate objects, the ability to perform mathematical operations and perseverance. As you can see, these are more psychological characteristics of the personality than mental abilities.

What is an IQ test used for?

Currently, the test is the only way to determine the level of a person's intelligence.

There are two ways to define intelligence. The first is intended for children 10-12 years old, with the help of the second, the development of children from 12 years old and adults is assessed. They differ in the level of complexity, but the principle of use is the same.

Each test has different tasks. To earn 100-120 points, which make up the average IQ, you do not need to strive to complete all the tasks. Half of the proposed tasks are sufficient. You have 30 minutes to complete the task. The most reliable result for a person is 100-130 points.

Aikyu level of a normal person - what is considered good

The level of intelligence in the range of 100-120 points, which is half of the correctly completed tasks, is considered the norm. The person who completes all tasks receives 200 points.

Also, this test helps to determine a number of psychological characteristics: attention, thinking, memory. By identifying shortcomings in abilities, one can help in their development and increase the aikyu index.

What determines the level of IQ

Psychologists are trying to establish the dependence of the level of intelligence on heredity, physiological data, gender or race. Several lines of research are being developed.

In the 19th century, scientists conducted a series of experiments to establish the dependence of the level of intelligence on physiological data and gender. They showed no connection. Other scientists have repeatedly stated that intelligence directly depends on the race of a person. These studies also found no relationship.

A number of researchers associate mental abilities with musical tastes. Music affects the emotional sphere. British scientists have found that the IQ is higher in people who prefer classical music, hard rock and metal. The minimum level of IQ, in their opinion, is among hip-hop and R'N'B fans.

What needs to be done to increase the aikyu coefficient

Increasing your IQ quotient requires constant training and brain development. Logic tasks and intellectual games, chess, crossword puzzles and poker are considered one of the effective ways. They help improve memory and increase concentration. Exact sciences develop analytical thinking. Mental development is influenced by reading fiction and learning foreign languages.

How much IQ does a normal person have

The average level of intellectual development is 100-120 points. However, scientists have long proposed to determine the level of IQ, taking into account chronological age. The test does not show the degree of erudition of the individual, but evaluates general indicators. Tests are designed to distribute results with an average score. The test indicates the direction in which a person should develop. An IQ level of 90-120 is considered good. However, it should be remembered that the results of the initial testing will be the most correct, further the data will be distorted.

Human intelligence is very difficult to define, it is almost impossible to measure. The accumulation of knowledge, abilities and skills occurs throughout a person's life.

The basis of intelligence is made up of several determining factors, genetics, environment, environment are important. Scientists have established a direct dependence of mental development on genes. The percentage of influence can range from 40 to 80 percent.

The development of the brain affects the level of intelligence and the aikyu index. The more developed a person's frontal lobes, which are responsible for thought processes, the higher the level of IQ.

Scientists pay special attention to the development of children in the first years of life and upbringing. The level of mental development was associated with the birth order of children in the family. For a long time it was believed that the first-born had a higher level of aikyu. Compared to younger children. Recent studies have shown that the birth order of children determines the developmental potential, the ability to reason and think, and as a result determine the level of development of the intellect. On average, first-born babies are age-appropriate on tests, but score a few points higher than younger siblings.

The development of mental abilities is influenced by the state of health. It is normal for a person to follow good habits and lead a healthy lifestyle. This allows you to keep your brain active. Scientists have proven that among people with a high level of intelligence, there are fewer patients with chronic diseases, their life expectancy is higher.

Aikyu scale level table by points

If the IQ test results are:

1-24 - profound mental retardation;
25-39 - severe mental retardation;
40-54 - moderate mental retardation;
55-69 - mild mental retardation;
70-84 - borderline mental retardation;
85-114 - medium;
115-129 - above average;
130-144 - moderately gifted;
145-159 - gifted;
160-179 - exceptionally gifted;
180 and above - deeply gifted.

Criticism of IQ tests

Determining the level of intelligence according to the proposed tests cannot be taken as a basis, since average indicators are taken as units of measurement, which change over time, which means they are not a standard.
Human intelligence depends on many factors, ranging from the time of day to the state of health.

Gender cannot be taken as a basis: among men and women there are people with both high and low IQ levels.
