Surely you have come across this concept more than once, and most likely, you have even taken one or another IQ test. But let's figure out what IQ gives us and why it is needed in general.

IQ test

So, intelligence quotient or IQ level is a quantitative assessment of the level of a person’s intellectual abilities compared to IQ normal person the same age as the subject. This indicator is determined using various tests, the most famous of which are the Eysenck, Wechsler, 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 applicants to take an IQ test. workplace, and applicants take it upon admission to a university.

In principle, IQ test questions are structured in such a way that their difficulty increases, so that the test taker must use his logical and spatial thinking. As a result of passing the test, you receive 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 level is from 111 to 130 points, you can safely consider yourself smart person. And if your score is above 131, then you are a lucky person who is included in 3% of the world's population. People with high IQs become outstanding scientists, inventors and explorers. There are geniuses with an IQ above 140, such as Bill Gates and Stephen Hawking, these people make up approximately 0.2% of humanity.

The level of intelligence is affected a large number of various factors, such as, for example, heredity, genes, sex and race of a person. According to recent studies, average level The IQ of an African American is 85, a Hispanic is 89, a white European is 103, an Asian (China, Japan, Korea) is 106, and a Jew is 113. It has also been found that most men have IQ scores higher than women.

The time-tested Eysenck test can be taken on the website iqtest.com at English language. There is no exact answer to the question: “What should IQ be” today, so if you are not satisfied with something, just work on increasing your level of intelligence. How? We will be happy to tell you about this.

How to increase your IQ

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

Method number 1 - get into the habit of playing intellectual games (for example, Scrabble, Sudoku, chess, and so on). These games are great exercises for the brain. When you learn to play one game well, move on - master the next one, because when you master a skill, your brain stops working as intensively to solve the problem, and 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 that focus on quick decision-making. It is also useful to solve logic puzzles, puzzles, crosswords and sudoku. All of these activities stimulate thought processes, increasing your IQ level.

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

Method number 3 - lead an active lifestyle, constantly exposing yourself physical activity, because this is a scientifically proven way to increase your intelligence level. Expand your horizons, set yourself a goal for life - not to stop learning, constantly learning something new. From time to time, give yourself a shake-up, jump with a parachute or try your hand at bungee jumping. New experiences release the hormone dopamine, which increases the number of neurons and produces a feeling of satisfaction. And in general, the more you know and can do, the richer your life experience, the higher the level of your intellectual development!

And here are a few more simple tips, which will help you enjoy life and increase your level of intellectual development.

  • Try to enjoy everything you do, enjoy classical music, good books and communicating with people you like.
  • Use electronic devices less. If you need to write something down, use a notepad and pen, and send a handwritten letter instead of an email. This stimulates visual and kinetic perception.
  • Learn to write with your non-dominant hand, which stimulates the hemisphere of your brain that is opposite to your hand.
  • Try to eat healthy 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 does the information received pass from short term memory in the long term.
  • Work on yourself and continue to learn throughout your life.

Every person is familiar with the term " IQ" and the abbreviation IQ. Many also know that IQ is assessed 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 quickly gained popularity in different countries. It began to be used to determine the IQ level not only in children, but also in military personnel. More than 2 million people have been tested. Later, IQ levels began to be determined among students and employees of private companies.

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

To solve problems you need to be good developed ability concentrate attention, ability to highlight the main thing, developed memory, great lexicon and fluency in spoken language, logical thinking, ability to manipulate objects, ability to perform mathematical operations and perseverance. As you can see, these are more psychological characteristics of the individual than mental abilities.

What is an IQ test used for?

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

There are two options for defining mental abilities. 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 includes different tasks. To earn 100-120 points, which constitute the average IQ, you do not need to strive to complete all tasks. Half of the proposed tasks are sufficient. You are given 30 minutes to complete the task. The most reliable result for a person is 100-130 points.

IQ level of a normal person - what is considered good?

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

This test also helps determine a number of psychological characteristics: attention, thinking, memory. By identifying deficiencies in abilities, you can help in their development and increase your IQ index.

What does IQ level depend on?

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

In the 19th century, scientists conducted a number 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 a person's race. These studies also found no relationship.

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

What to do to increase your IQ ratio

Increasing your IQ requires constant training and brain development. One of effective ways Logical tasks and intellectual games, chess, crosswords and poker are considered. They help improve memory and increase concentration. Studying the exact sciences develops 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 IQ level taking into account chronological age. The test does not show the degree of erudition of an individual, but evaluates general indicators. The tests are designed to distribute results around the average. The test indicates the direction in which a person should develop. Counts good level IQ 90-120 points. However, it should be remembered that the results of the initial testing will be the most accurate; further data will be distorted.

Human intelligence is very difficult to define and 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, and 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 level of intelligence and the IQ index are influenced by the development of the brain. The more developed a person’s frontal lobes, which are responsible for thought processes, the higher the IQ level.

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 order of birth of children in the family. For a long time it was believed that first-born children have a higher level of IQ. Compared to younger children. Recent studies have shown that the birth order of children determines the developmental potential, ability to reason and think, and as a result determine the level of intellectual development. On average, children born first, when taking tests, show compliance with the norm for their age, but score several points more than younger brothers and sisters.

The development of mental abilities is influenced by health status. It's normal for a person to follow good habits and lead healthy image life. This allows you to maintain brain activity in good shape. Scientists have proven that among people with a high level of intelligence, there are fewer patients with chronic diseases and 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 - average;
  • 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 using the proposed tests cannot be taken as a basis, since the units of measurement are average indicators that change over time, which means they are not a standard.
A person’s intelligence depends on many factors, ranging from the time of day to the state of health.

You can’t take gender as a basis: among men and women there are people with both high and low IQ levels.

Last update: 06/03/2017

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

IQ, or intelligence quotient, is a score obtained on a standardized test designed to measure intelligence. Formally, it is believed 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 debate 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 administering the test to 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 an intelligence test, as a rule, the normal distribution function is used - a bell-shaped curve in which most results are located near or around the average score. For example, the majority of scores (about 68%) on the WAIS III test tend to fall between 85 and 115 points (with an average of 100). The remaining results are less common, which is why the area of ​​the curve on which they are located is directed downward. Very few people (approximately 0.2%) score more than 145 (indicating a very high IQ) or less than 55 (indicating a very low IQ) on the test.
Because the average score is 100, professionals can quickly evaluate individual scores by comparing them to the mean and determining where they fall on a normal distribution scale.

More about IQ scores

In most modern IQ tests, the average score is set at 100 points with a standard deviation of 15 points - so that the scores follow a bell curve. This means that 68% of the results fall within one standard deviation from the mean (that is, between 85 and 115 points), and 95% fall within two standard deviations (between 70 and 130 points).
A score of 70 or below 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, IQ test results alone are not used to diagnose intellectual disability. Approximately 2.2% of people score below 70 points.
A score greater than 140 is considered a high IQ. Many people believe that a score of more than 160 points can indicate a person’s genius.
A high IQ is certainly closely related to academic performance, but is it related to success in life at all? Are there people truly more successful than their counterparts with lower IQs? Many experts believe that other factors may also have a big impact, including.
That is, the scores are interpreted as follows.

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

general information

The abbreviation IQ stands for what can be translated as “amount of intelligence.” In the Russian-speaking language environment, the 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 really be trusted, it is worth taking into account not only the results of the test itself. Other factors such as age and gender need to be taken into account.

Many also believe that the results of this test are more likely to indicate a person's aptitude for a particular type of task, rather than actual intellectual ability. Therefore, you can prepare for it by solving problems 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 IQ through various experiments. Scientists tried to find a pattern that would connect the processes of the central nervous system, reaction 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 relationship to social origin, age, and so on.

IQ test today

It is now generally accepted that IQ depends on many factors, mostly 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 it is motivation and perseverance. Individuality, determination and ambition also play an important role. However, 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 vocabulary exercises, today they use a wide variety of tasks. Among them are counting exercises, logical series, the ability to find the missing geometric figure, the ability to recognize a fragment, remember facts, technical drawings and identify 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 also determines other indicators; it helps to identify the way of thinking of the person who is taking it. By identifying the category in which the subject has the lowest level of ability, you can help him identify gaps in his abilities, practice with different types tasks and raise your IQ.

First tests

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

Averages

It is rightfully believed that an IQ test does not show a person’s level of erudition, but only an assessment of general indicators. They are designed specifically to produce 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 between 90 and 100 points, a quarter - below 90, and the other quarter - above 110 units. The average score for graduates of American universities is 115 points, with excellent students ranging 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 a person, but they should not be assumed to 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. The Eysenck test is most often used to determine IQ. However, do not forget that the most accurate results will be those obtained the very first time you take the test, and all subsequent attempts will only distort them.

The highest IQ level is for an Australian mathematician, the author of the Green-Tao theorem, his name is Terence Tao. Getting results above 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 and make discoveries in various professional fields. Among them are the American writer Marilyn vos Savant, astrophysicist Christopher Hirata, phenomenal reader Kim Pik, who can read a page of text in a few seconds, Briton Daniel Tammet, who memorizes thousands of numbers, Kim Ung-Yong, who already studied at the university at the age of 3, and other famous personalities with amazing abilities.

How is a person's IQ formed?

IQ level is influenced by several factors, including heredity, environment (family, school, social status person). The test result is also significantly influenced by the age of the test taker. At the age of 26, as a rule, a person’s intelligence reaches its peak, and then only declines.

It is worth noting that some people with exceptionally high IQ Everyday life were completely helpless. For example, Kim Pik could not fasten the buttons on his clothes. Moreover, not everyone had such talent from birth. Daniel Tammet gained his ability to remember huge numbers of numbers after a terrible attack of epilepsy as a child.

IQ level above 140

People with IQ scores over 140 are the owners of excellent creativity who have achieved success in various scientific fields. Famous people with IQ test scores of 140 or higher 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, creating new inventions and theories. Such people make up only 0.2% of the entire population.

IQ level from 131 to 140

Only three percent of the population has high IQ scores. Among famous people who have a similar test result are Nicole Kidman and Arnold Schwarzenegger.

People with such intelligence indicators do well in school and universities, they get jobs in middle management and other professions that do not require significant mental effort.

IQ level from 81 to 90

A tenth of the population has a below average intelligence level. Their IQ test scores range from 81 to 90. These people usually do well in school, but most often do not go on to 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
