Instructions. Before you start taking mental tests, we would like you to become familiar with the rules of self-testing:

1. The following pages contain a test that consists of 50 tasks. It measures your learning and cognitive abilities.

2. To complete all test tasks you are given a strictly defined time - 15 minutes. Therefore, when starting to complete the test tasks, turn on the stopwatch or note the time to the nearest second, or even better, ask someone to keep track of the time.

3. The test to measure intellectual ability can only be used once. Therefore, if out of curiosity you get acquainted with the content of test tasks or the correct answers, then with their help you will no longer be able to obtain an accurate assessment of your capabilities. For the same reason, when you start taking tests, don't get ahead of yourself to the correct answers. You can evaluate the correctness of your answers only by completing the entire test.

4. Start self-testing only when you are well rested and alert. Before you start taking tests, choose a comfortable place where you will not be distracted during the entire testing period. Ask your loved ones not to disturb you, turn off the phone, turn off the TV and radio. You should not discuss tasks with anyone while working and do not allow anyone to help you.

5. Work as quickly as possible. If you do not immediately find the answer to any test item, do not linger on it for too long, move on to the next one. Remember that no one person will be able to solve all the questions on this test correctly in the allotted time.

6. Your answer in each case will consist of a single number or a pair of numbers. You can choose from several suggested options or come up with the correct answer yourself.

Correct answers to the IQ test

Once you have completed this test, you can calculate your results. The table following the test contains the correct answers to all tasks. For each match between your answer and the correct one, award yourself one point. Now calculate the sum of your correct answers. The higher your score on this test, the higher your current level of intellectual development, the better your abilities for further learning and cognitive activity.

If the test score you received is 24 points or more, then the level of your intellectual abilities allows you to begin mastering a wide range of professions right now. In addition, your level of intellectual development is sufficient for you to be able to count on fairly high success in performing activities in any creative class profession.

And if your score exceeds 30 points, then you can be proud of your results. Few people reach such a high level of development of intellectual abilities.

Test scores of less than 16 points are considered low.

Firstly, a low result may not be reliable enough due to possible errors in compliance with test conditions and understanding of instructions. Therefore, a low test result on this test can in no way be a sign of psychological professional unsuitability for any specialty. Only testing using other methods that are at the disposal of psychologists can provide accurate and reliable information about psychological contraindications to certain professions.

Secondly, if you did not receive a high enough score on this intelligence test, it can be assumed that you will experience certain difficulties in the process of professional training and further practical activity in the field of creative professions. These difficulties may be caused by one or more reasons:

1) Insufficiently high level of development of the ability to concentrate attention on the tasks being solved.

2) Insufficient skills in material analysis, abstract thinking, logical reasoning, quantitative calculations, spatial imagination.

3) Insufficient amount of available knowledge, limited vocabulary, low literacy.

4) Insufficiently high tempo of mental activity and the ability for prolonged mental stress.

To successfully complete the test, a certain level of development of verbal, logical, numerical and spatial abilities is required. These qualities are very important in order to be able to learn, absorb new information, analyze complex situations and make reasonable decisions. If you do not possess these qualities to the proper extent, then it may be difficult for you to engage in complex types of intellectual activities, such as studying, problem solving, making non-standard and responsible decisions, organizing your own work and the work of others, management, planning, control, research , construction and design.

It is within your power to develop your intellectual qualities. After all, the level of development of intellectual abilities is not a person’s height or blood type, which cannot be changed. Intellectual capabilities are not only a condition of learning, but also the result of previous learning. Intelligence tests are not intended to measure the inclinations of mental development, but only the level of development of skills and abilities of cognitive activity that you have developed today.

What is this mysterious “IQ Test”?

All people are different. Therefore, it is not surprising when one person has a more developed level of intelligence compared to another. Each of us has a certain idea of ​​our capabilities. But how to measure them accurately? In this case, in most developed countries of the world, it is the IQ test, expressed in points, that comes to the rescue.

Translated from English, the abbreviation IQ means “intelligence quotient.” This indicator is a quantitative assessment of the level of intelligence of an individual in comparison with the same indicator belonging to the average person of the same age as the test subject. IQ can be determined by passing the tests presented above, which (as experts point out) may not assess an individual’s existing knowledge, but they do determine his thinking abilities. Our IQ tests are free chances to find out how developed your intelligence is!

The structure of each IQ test is a list of questions, which are both simpler and more difficult. The subject is asked to cope with tasks related to determining the quality of spatial and logical thinking in a person. There are very different variations of questions. As practice shows, the higher the experience in passing these tests, the better the results. The Eysenck test is the most famous among such IQ tests.

Scientists note that half of people have an IQ in the range of 90-110 points, the rest are either below 90 or above 110 (about 25% each). According to American researchers, the average score of this test among graduates of higher educational institutions is 105 points. For excellent students it is 130-140. It is believed that you need to work on improving your mental abilities when your IQ is below 70.

In recent years, IQ tests have gained incredible popularity among the entire population of the planet. They are used everywhere: when applying to universities and colleges, during job interviews, when passing driver's license exams, and so on. Russia also did not stand aside. The population of our country is entirely interested in knowing the level of their own intelligence, which is why many residents try to learn as much as possible about tests to determine intellectual abilities and are not averse to taking them. The big advantage of such intelligence tests is their accessibility. If you search the Internet for IQ tests, you will certainly find free ones. Moreover, not all of them will be correctly composed. The uniqueness of our site is that we give you the opportunity not just to take a free IQ test, but to try to pass a test compiled by an experienced specialist. That is, we have real IQ tests.

It is worth noting that the average IQ of the population of a particular country depends on the efficiency of the state machine and the level of gross domestic product. In addition, a study was conducted that found a relationship between the social intelligence factor and average results on the Unified State Exam (the foreign analogue of the SAT).

IQ tests: how they are constructed

There are other variations of questions. As practice shows, the more experience you have in passing these tests, the better the results. The most famous among such tasks is the Eysenck test. Good accuracy is demonstrated by tests bearing the names of their creators: D. Wexler, J. Raven, R. Amthauer and R. B. Cattell. At the same time, to date no one has yet introduced a single standard to which existing IQ tests would adhere.

All tests are divided into groups by age in order to give an accurate assessment of a person’s intellectual development, corresponding to his age. In other words, the results of IQ tests can be the same - for example, an 11-year-old child and a master's degree in mathematics. This is all because they are equally developed for their age. If we take the Eysenck test, the creator developed it to determine the level of intelligence in people over 18 years of age.

History of IQ and what influences it

Back in 1912, the German scientist Wilhelm Stern introduced the then unusual concept of “intelligence quotient” to the general public for the first time. While conducting his research, he turned his attention to the shortcomings inherent in one of the indicators of the Binet scales, namely mental age. To determine an accurate assessment of an individual's intelligence, Stern proposed dividing mental age indicators by real age (also called chronological), and taking the remainder of this operation.

The first appearance of the term IQ dates back to 1916, when it was used in the Stanford-Binet scale. But today (perhaps due to the greatly increased interest among the population in IQ indicators) there are several other scales, the validity of which has not been proven. Therefore, it is now quite difficult to compare the results shown by different tests. Therefore, psychologists often recommend turning to classical tests to determine the IQ. These are the tests we have selected for you.

Reasons affecting IQ

Naturally, one of the main reasons that has a serious impact on IQ levels is heredity. The main emphasis in the ongoing research on determining the relationship between these two indicators was on children. The results of these studies resulted in quite a wide range of readings: some scientists stated that less than half of IQ depends on existing genes; and others even cited data reporting almost one hundred percent dependence. The rest that could affect the results of IQ tests is the environment and situation, as well as all sorts of errors inherent in such measurements. That is, according to such studies, it turns out that the level of IQ largely depends on hereditary genes.

Another reason that influences IQ scores is individual genes (the brain activity of an ordinary person depends on approximately 17 thousand genes). Research shows that individual genes influence an individual's existing IQ level, but in fact their influence does not have a strong effect. This dependence, revealed during the research, turned out to be at the level of statistical error.

Currently, research has begun to look for differences in the genome in people with high and low IQ levels. If someone manages to figure out the genetic causes of “braininess,” then perhaps there will be a means to increase a person’s IQ level. States with such knowledge will quickly move forward in terms of economic and technological development.

The third reason that can affect IQ level is the environment. Of course, everything that is around a person (especially the family) influences his development. Research has identified many factors for this dependence. They included family income, the size of the house and its price, the developing relationships between all family members, and so on. This dependence is characterized by a coefficient equal to 0.25-0.35. But as a person grows older, this influence gradually decreases until it reaches zero around adulthood (these studies concerned only a full family with two parents and two children).

Improper nutrition can also affect the level of IQ development. Thus, recent studies have shown that eating fish products by a pregnant woman has a beneficial effect on the intellectual development of her unborn child.
Another study, involving about 13 thousand people, determined that breastfeeding also has a positive effect on the infant's intelligence. However, it should be noted that immediately after the publication of this study it was criticized. The reasons for the scientific “attack” were an incorrect analysis of the data obtained and a complete disregard for existing theories.

Differences in IQ across human groups

According to most experts, on average, there is no significant difference in the level of intelligence development between men and women belonging to the same age group. But it is among the male population that the most striking dispersion in this indicator is observed: that is, there are a lot of men with a high level of intelligence and also a lot of those whose IQ is quite low. In addition, this indicator is expressed slightly differently in women and men. This is especially noticeable after five years. At this age, boys begin to show superiority over the fair half of humanity in terms of spatial intelligence and manipulation. Girls demonstrate better verbal functions.
Men are also gaining leadership in the area of ​​mathematical abilities. One of the American researchers came to the conclusion that for every 13 men who have excellent abilities in mathematical operations, there is only one woman equal to them.

Racial differences

Numerous studies have been conducted to identify differences in the average IQ level among residents of the United States of America and have led to the following conclusion: among representatives of the African-American population this indicator was 85 points, among Latinos - 89, whites - 103, Asians - 106, and Jewish - 113.

At the same time, the average IQ level, if we consider data from tests half a century ago, shows some changes. So, today the IQ of the Negroid race in 1995 corresponds to the IQ of white people who lived in 1945. Therefore, it seems impossible to “blame” everything on the genetic characteristics of people.

One should not ignore such an important factor as the influence of society on the development of intelligence. This is especially noticeable in orphans. For example, in the same USA, the IQ level of children raised by representatives of the white race is approximately 10% higher than that of those who lived in a black family. And in the UK, this indicator varies even more interestingly: in boarding schools, black children have a higher IQ than their white peers.

During the research, scientists discovered a pattern in the existing difference in the average IQ level between residents of different countries. According to certain data, this indicator is influenced by the current size of GDP, the practical use of democratic principles, crime and birth rates of the population, and the percentage ratio between believers and atheists. In developing countries, in addition to the above reasons, the average IQ level and poor quality nutrition, coupled with numerous diseases, also have an impact. In this regard, we ask you to familiarize yourself with this interesting map...

Relationship between health, age and IQ

A properly composed diet, especially in the early stages of human development, has a beneficial effect on the development of intellectual abilities. An example is the factor of iodine deficiency in the body: if it is present, the average IQ score decreases by 12 points. Those who have a fairly high IQ live longer and get sick less often.

IQ acts as a measure of a person's intellectual abilities, which reach maximum values ​​at 26 years of age. Then they gradually decrease.

The IQ of an adult, to a greater extent than that of children, is determined by genetic inheritance. For the latter, this indicator is influenced by the environment. Due to certain life characteristics, some children are initially ahead of their peers in terms of intelligence, but over time their indicators level out.

Representatives of the American Psychological Association noted that children whose results on IQ tests are high are much better at mastering the material presented in school than those who receive lower scores. This correlation reaches 0.5. Tests to determine the level of intelligence make it possible to pre-select naturally gifted children in order to teach them in a separate, accelerated program.

Revenues, scrime and IQ

Some of the research devoted to the influence of IQ level on a person’s life shows that higher intelligence increases the productivity of an individual and, accordingly, his income increases. Moreover, this indicator does not depend on a person’s social environment, including his family.

The American Psychological Association noted in one of its reports that intelligence level has little to do with a person’s propensity to commit crimes. The correlation in this case is only 0.2. It is important to note here that cause-and-effect relationships are indirect. That is, poor performance at school is not always explained by a low IQ level, but it often influences the possibility of a person becoming criminal.

Arthur Jensen provides information according to which the largest percentage of crimes occurs among people with an IQ ranging from 70 to 90 points.

Scientific achievements, etc.ore activity

According to some studies, it can be concluded that success in the scientific field is largely dependent on character traits such as determination and innovative thinking. But Dr. Eysenck cites other data according to which the level of intelligence of successful scientists is lower than that of their colleagues who received the Nobel Prize. The average IQ test scores were 166. At the same time, some scientists demonstrated the highest possible level of 177 points. Spatial IQ was, according to the scientist, 137 points, although at a younger age it should have been higher. And the average mathematical IQ is 154.

Two scientists, Frank Schmidt and John Hunter, came to the conclusion that, given an equal amount of experience, the person with the higher IQ level will be more productive. As researchers note, the development of intelligence affects all types of human activity, but its level differs depending on the chosen field of activity. From this we can conclude that work that requires long-term brain work will not be available to those with a low IQ. And at the same time, the size of this coefficient will not seriously affect activities related to physical activity.

Intelligence tests have become an important part of modern life. Everyone goes through them periodically, wanting to learn as much as possible about themselves and their intellectual capabilities. Employers are interested in their results, offering available vacancies to certain applicants who meet the necessary requirements. Each online intelligence test allows you to reveal those facets of character and knowledge that until now remained “behind the scenes”, but after successful testing a person begins to use his hitherto hidden potential.

Online intelligence tests are also convenient because you don’t have to wait long for results (let alone pay for them). You can always estimate in advance the time that will be spent on testing, and also choose exactly those tests that will be useful at this particular moment.

As for the term “intelligence test” itself, it was first used in 1911 by Austrian psychologists, and much later the prefix “online” was added to it. The modern business world (especially in Europe and America) widely uses such “intelligence testing” in most psychological examinations. A series of online tests have already been developed for students of schools, universities and colleges, with the help of which teachers determine the mental and intellectual development of younger generations. Even preschool institutions can no longer imagine their activities without development tests. The first such tests for children were created by a psychologist from France A. Binet.

Each IQ test must meet certain criteria. Among them, time plays a special role: for each level a person is given a certain time limit, which absolutely cannot be exceeded. This allows us to more adequately evaluate the results obtained. Most online intelligence tests consist of arithmetic problems and examples, where you either need to create a whole figure from disparate elements, or choose the missing (extra) item using logical thinking and associative series. Such a variety of tasks allows you to assess the level of human development from all sides, giving a more complete picture.
