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 a very high IQ) or less than 55 (indicating a 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 main thing is not to blame the complexity of the test and the suboptimal state of mental abilities. Then people will respect you.

We have tested 3 173 578 Human!

Intelligence quotient (eng. IQ - intelligence quotient) - a quantitative assessment of the level of intelligence of a person: the level of intelligence relative to the level of intelligence of an average person of the same age. It is determined using special tests. IQ tests are designed to assess mental abilities, not the level of knowledge (erudition). The IQ is an attempt to measure the general intelligence factor (Wikipedia).

The IQ test lasts 30 minutes and contains 40 simple questions!

When performing the test, you can not use paper, a calculator, a pen, a cheat sheet, the Internet and friend's tips :) IQ tests are designed so that the results are described by a normal distribution with an average IQ value of 100 and such a spread that 50% of people have an IQ between 90 and 110 and 25% each below 90 and above 110. The average IQ of American university graduates is 115, excellent students - 135-140. An IQ value of less than 70 often qualifies as mentally retarded.

We have all come across the expression “IQ” (IQ) more than once. Especially often you can hear this term when it comes to the mental and intellectual development of a person. Actually, "IQ" means intelligence quotient. And today we will talk in detail about what it is, and with what, so to speak, it is “eaten”.

The term "intelligence quotient" comes from the English phrase "intelligence quotient" and is a quantitative assessment of the level of intelligence of a person, i.e. the level of his intelligence compared to the level of intelligence of an average person of the same age. Specialized tests are used to determine the IQ. But we'll talk about the tests a little later, but for now let's delve a little into the history.

Brief historical background

The term "intelligence quotient" was first introduced in 1912 by the German and philosopher Wilhelm Stern. It was he who put forward the proposal to use the results of dividing a person's mental age by chronological age as the main indicator of intellectual development. Four years later, in 1916, the IQ was used for the first time in the Stanford-Bene intelligence scale.

Over time, people's interest in IQ tests became stronger, which was the reason for the emergence of a huge number of various scales, among which there are often unsupported ones. Based on this, today it is rather problematic to compare the results of different tests. But, despite the fact that the IQ indicator itself began to lose its value, a huge number of people around the world continue to undergo all kinds of tests to determine the level of their intellectual development.

IQ Tests

Each person is able to increase the level of his intellect. The main thing is to constantly learn and not stand still. And for an additional one, you should always remember that people with a high IQ are much less susceptible to various diseases and live longer.

People have different skills and levels of intelligence: verbal, typical, spatial, conceptual, mathematical

IQ–

The concept of "intelligence quotient" was introduced by the German psychologist William Stern.. He used IQ as an acronym for Intelligenz-Quotient – intelligence quotient. IQ was a score obtained from a series of standardized tests administered by a psychologist to determine the level of intelligence.

Mind Research Pioneers

At first, psychologists doubted that the human mind could be measured, much less accurately. While interest in measuring intelligence goes back thousands of years, the first IQ test has only recently appeared.

In 1904, the French government asked the psychologist Alfred Binet to help determine which students were most likely to have difficulty in school. The need to establish the intelligence of schoolchildren arose so that they could all receive compulsory primary education.

Binet asked his colleague Theodore Simon to help him design a test that would focus on practical issues like memory, attention and problem solving, things kids don't learn in school. Some answered more difficult questions than their age group, and so, based on observational data, the now classic concept of mental age has emerged. The result of the work of psychologists - the Binet-Simon scale - became the first standardized IQ test.

By 1916, Stanford University psychologist Lewis Terman had adapted the Binet-Simon scale for use in the United States. The modified test was called the Stanford-Binet Intelligence Scale and became the standard intelligence test in the United States for several decades. Stanford - Bean uses a number known as IQ - intelligence quotient to represent an individual's score.

The intelligence quotient was originally determined by dividing the mental age of the person taking the test by their chronological age and multiplying the quotient by 100. It goes without saying that this only works (or is best suited) for children. For example, a child with a mental age of 13.2 years and a chronological age of 10 years has an IQ of 132 and is eligible to enter Mensa (13.2 ÷ 10 x 100 = 132).

During World War I, the United States Army developed several tests to select recruits for specific jobs. The Army's "Alpha" test was a written test, while the "Beta" test was given to illiterate recruits.

This and other IQ tests have also been used to test new immigrants coming to the US from Ellis Island. Their results were used to fabricate false generalizations about the "surprisingly low intelligence" of Southern European immigrants and Jews. These results in 1920 led to proposals by the "racially motivated" psychologist Goddard and others to Congress to impose restrictions on immigration. Despite the fact that the tests were conducted only in English, and the vast majority of immigrants did not understand it, the United States government deported many thousands of deserving people who were labeled as "unfit" or "undesirable." And this happened a decade before Nazi Germany started talking about eugenics.

Psychologist David Wexler was dissatisfied, in his opinion, with the limited Stanford-Binet tests. The main reason for this was the single score, its emphasis on time limits, and the fact that the test was designed specifically for children, and therefore not suitable for adults.

As a result, during the 1930s, Wexler developed a new test that was known as the Wexler Bellevue Intelligence Scale. The test was subsequently revised and became known as the Wechsler Adult Intelligence Scale, or WAIS. Instead of one overall assessment, the test created an overall picture of the subject's strengths and weaknesses. One advantage of this approach is that it also provides useful information. For example, high scores in some areas and low scores in others are indicative of a specific learning disability.

WAIS was psychologist Robert Wechsler's first test, while WISC (Wechsler's Childhood Intelligence Scale) and Wechsler's Preschool Intelligence Scale (WPPSI) were developed later. The adult version has since been revised three times: WAIS-R (1981), WAIS III (1997) and in 2008 WAIS-IV.

Unlike tests based on chronological and mental age scales and standards, as in the case of Stanford-Binet, all versions of WAIS are calculated by comparing the test person's score with that of other test subjects of the same age group.

The average IQ score (worldwide) is 100 with 2/3 of the scores in the "normal" range of 85 to 115. WAIS norms have become the standard in IQ testing and are therefore used by the Eysenck and Stanford-Binet tests, with the exception that the standard deviation is not 15, but 16. The Cattell test has a deviation of 23.8 - it often gives very flattering IQs, which can mislead uninformed people.

High IQ - high intelligence?

IQ for the gifted is determined using special tests which provide psychologists with a wealth of useful information. Many of them the average score is fixed at the level of 145-150, and the full range is between 120 and 190. Scores below 120 are not designed for the test, and scores above 190 are very difficult to interpolate, although it is possible.

Paul Kooijmans from the Netherlands is considered the founder of upper range IQ tests, and he is the creator of most of the original, and now classic, tests of this type. He also founded and administers the super-high IQ societies Glia, Giga, and Grail. Among the most famous and popular Kooijmans tests are the Genius Test, the Nemesis Test, and the Kooijmans Multiple Choice Test. Paul's presence, influence and participation is a must, it's an integral part of the spirit of ultra-high IQ tests and its communities at large. Other classic IQ test gurus are Ron Hoeflin, Robert Lato, Laurent Dubois, Mislav Predavec, and Jonathon Wye.

There are different types of thinking that manifest themselves differently at different levels.. People have different skills and intelligence levels: verbal, typical, spatial, conceptual, mathematical. But there are also different ways to manifest them - logical, lateral, convergent, linear, divergent, and even inspirational and ingenious.

Standard and Elevated IQ Tests Reveal General Intelligence Factor; but in high-level tests it is defined in different ways.

There is a lot of talk about high IQ scores being called genius IQs, but what do these numbers really mean and how do they add up? What IQ score is a sign of genius?

High IQ is any score above 140.

Genius IQ- more than 160.

great genius– the score is equal to or greater than 200 points.

High IQ is directly related to academic success, but does it have an impact on success in life in general? How much luckier are geniuses than people with lower IQs? Some experts believe that compared to other factors, including emotional intelligence, IQ is of lesser importance.

Breakdown of IQ scores

So how exactly are IQ scores interpreted? Average IQ test score is 100. 68% of IQ test results fall within the standard deviation of the mean. This means that most people have an IQ between 85 and 115.

Up to 24 points: profound dementia.

25–39 points: severe mental disability.

40–54 points: moderate dementia.

55–69 points: mild mental disability.

70–84 points: borderline mental disorder.

85–114 points: average intelligence.

115–129 points: Above average level.

130–144 points: moderate giftedness.

145–159 points: high endowment.

160–179 points c: exceptional talent.

over 179 points: deep endowment.

What does IQ mean?

When talking about intelligence tests, IQ is called "giftedness scores". What do they represent in assessing IQ? To understand this, it is important to first understand testing in general.

Today's IQ tests are mostly based on the original tests., developed in the early 1900s by a French psychologist Alfred Binet to identify students in need of additional assistance.

Based on his research, Binet developed the concept of mental age. Children in some age groups quickly answered questions that were usually answered by older children - their mental age exceeded chronological age. Binet's measurements of intelligence were based on the average abilities of children in a certain age group.

IQ tests are designed to measure a person's ability to solve problems and reason. The IQ score is a measure of fluid and crystallized intelligence. The scores indicate how well the test was done compared to other people in that age group.

Understanding IQ

The distribution of IQ scores follows the Bell curve– a bell-shaped curve, the peak of which corresponds to the largest number of test results. The bell is then lowered on each side, with scores below average on one side and above average on the other.

The mean value is equal to the mean score and is calculated by adding all the results and then dividing them by the total number of points.

Standard deviation is a measure of variability in a population. A low standard deviation means that most of the data points are very close to the same value. A high standard deviation indicates that the data points tend to be further from the mean. In IQ testing, the standard deviation is 15.

IQ increases

With each generation, IQ increases. This phenomenon is called the Flynn effect. named after explorer Jim Flynn. Since the 1930s, when standardized tests became widespread and researchers note a steady and significant increase in test scores in people around the world. Flynn suggested that this increase is due to an improvement in our ability to solve problems, think abstractly, and use logic.

According to Flynn, past generations mostly dealt with the concrete and specific problems of their immediate environment, while modern people think more about abstract and hypothetical situations. Not only that, but approaches to learning have changed dramatically over the past 75 years, and more people are, as a rule, engaged in mental work.

What do the tests measure?

IQ tests evaluate logic, spatial imagination, verbal reasoning, and visual ability. They are not intended to measure knowledge in specific subject areas, as an intelligence test is not something that can be learned in order to improve one's score. Instead, these tests assess the ability to use logic to solve problems, recognize patterns, and quickly make connections between different information.

While it is common to hear that prominent figures such as Albert Einstein and Stephen Hawking have IQs of 160 or higher, or that certain presidential candidates have specific IQs, these numbers are merely estimates. In most cases, there is no evidence that these well-known individuals ever took a standardized IQ test, let alone made the results public.

Why is the average score 100?

Psychometrists use a process known as standardization to compare and interpret IQ scores. This process is carried out by conducting a test on a representative sample and using its results to create standards or norms against which individual scores can be compared. As average score is 100, experts can quickly compare individual scores with the average to see if they fall within a normal distribution.

Grading systems can vary from one publisher to another, although many tend to follow the same grading system. For example, on the Wechsler Adult Intelligence Scale and on the Stanford-Binet test, scores in the range of 85–115 are considered "average".

What exactly do the tests measure?

IQ tests are designed to assess crystallized and fluid mental abilities.

crystallized includes knowledge and skills acquired throughout life, and mobile The ability to reason, solve problems, and make sense of abstract information.

Mobile intelligence is considered to be independent of learning and tends to decline in later life. crystallized is directly related to learning and experience and is constantly increasing over time.

The intelligence test is administered by licensed psychologists. There are various types of tests, many of which include a range of subtests designed to measure math ability, language skills, memory, reasoning skills, and processing speed. Their scores are then combined to form a total IQ score.

It is important to note that while average, low, and genius IQs are often spoken of, there is no single test for intelligence. Many different tests are used today, including the Stanford-Binet, the Wechsler Adult Intelligence Scale, the Eysenck test, and the Woodcock-Johnson cognitive tests. Each of them differs in what exactly and how it is evaluated, and how the results are interpreted.

What is considered low IQ?

An IQ equal to or below 70 is considered low. In the past, this IQ was considered the standard for mental retardation, an intellectual disability characterized by significant cognitive impairment.

Today, however, IQ by itself is not used to diagnose intellectual disability. Instead, the criterion for this diagnosis is low IQ, with evidence that these cognitive limitations existed before the age of 18 and involved two or more adaptive areas such as communication and self-help.

About 2.2% of all people have an IQ score below 70.

So what does it mean to have an average IQ?

IQ level can be a good general indicator of reasoning and problem solving ability, but many psychologists suggest that the tests do not reveal the whole truth.

Among the few things they fail to measure are practical skills and talents. A person with an average IQ may be a great musician, artist, singer, or mechanic. Psychologist Howard Gardner developed the theory of multiple intelligences to address this shortcoming.

In addition, the researchers found that IQ can change over time. A study of the intelligence of adolescents with a gap of 4 years gave results, the values ​​of which varied by 20 points.

IQ tests also do not measure curiosity and how well a person understands and owns emotions. Some experts, including writer Daniel Goleman, suggest that emotional intelligence (EQ) may be even more important than IQ. The researchers found that high IQ can really help people in many areas of life, but it does not guarantee success in life.

So there is no need to worry about the lack of genius, since the vast majority of people are not geniuses. Just as a high IQ does not guarantee success, an average or low IQ does not guarantee failure or mediocrity. Other factors such as hard work, resilience, perseverance and general attitude are important pieces of the puzzle. published
