IQ is one of those words that we use a lot, one of those words that we have changed the original meaning a little bit. Have you noticed that instead of its true meaning, which is IQ, it sometimes finds the irony of being unconscious or careless? After all, what is the true meaning of IQ? What is a normal IQ? In this article, we will talk about this coefficient and its normal value.
What is IQ?
IQ (Intelligence quotient) is an accepted measure for measuring the mental abilities of individuals. This criterion measures cognitive skills such as reasoning, logic, and problem solving.
IQ test or IQ test has little to do with your knowledge. In fact, this test examines the innate abilities of your mind. Education, learning and the environment can enhance innate mental abilities.
The IQ test should be performed in the presence of a professional. There are many tests on the Internet these days to measure intelligence, but most of them are fun. The results of such tests are not very reliable.
There is another important point about this intelligence test. An IQ test is a comparison of the average mental abilities of people with similar conditions, such as people of the same age.
What is a normal IQ?
What is a normal IQ and how much does it make you think about having good intelligence and senses? A typical IQ is between 90 and 109. Adult IQ is usually between 70 and 130.
If your IQ is more than 130, your IQ is above average. An IQ below 70 also indicates that a person’s intelligence is lower than the average adult’s intelligence. Of course, in different age groups, the normal number for IQ is different:
16 to 17 years: The average IQ is 108.
18 to 19 years: The average IQ is normally 105.
20 to 24 years: The average IQ is normal 99.
24 to 34 years old: The average IQ is slightly less than 97.
35 to 44 years: The average IQ is 101.
45 to 54 years: The average normal IQ is 106.
55 to 64 years: The average IQ is 109.
65 to 69 years: The average normal IQ is 114.
70 to 74 years: The average normal IQ is 119
What is the application of IQ test?
Assessing a person’s mental abilities to be assigned to a job position;
Assessing the academic abilities of individuals;
Diagnosis of mental disabilities;
Advancing psychological research;
Assess people’s cognitive skills such as attention span, memory status, math skills, problem solving ability and speed of action.
What is the maximum IQ?
It is not clear what the maximum IQ is, ie there is no limit to it. It is not clear who has the highest IQ in this world. Changes in IQ tests over the years prevent the results from being compared over different years.
Terence Tao is a mathematician whose IQ is said to be 220 or 230. He went to school at the age of 7, completed his bachelor’s degree at the age of 16 and his doctorate at the age of 21.
In 2017, the India Times reported the existence of an 11-year-old girl with an IQ of 162. The IQ of the late Einstein and Stephen Hawking was also 160.
How is IQ measured?
The IQ test is designed to measure crystalline intelligence and fluid intelligence. Crystallized intelligence includes abilities and skills that are acquired throughout life. Fluid intelligence also includes the mind’s ability to reason, solve problems, and understand abstract concepts and information.
The fluid type of intelligence has nothing to do with learning and decreases in adulthood. Crystallized intelligence is directly dependent on experience and learning and increases with adulthood.
Expert psychologists can conduct and analyze IQ tests. The IQ test does not have just one form and method, and the following are measured in the form of various tests:
Ability to reason;
Brain processing speed;
Linguistic abilities such as vocabulary;
The individual’s ability to process visuospatial.
Some of the IQ tests are:
Wechsler for adult intelligence assessment;
Wechsler test for children;
Kaufman children evaluation battery;
Cognitive evaluation system;
Woodcock-Johnson Cognitive Skills Tests.
Several controversial factors affecting IQ
There are several tests for measuring IQ. These tests have changed over time and will change again. Therefore, we may not be able to consider IQ as a completely reliable criterion. In the following, we will examine some of the factors that have become controversial.
Research has shown that race can affect an individual’s IQ. However, research has not shown that racial differences are more due to climate and environment or genetics. The indefinable connection between environment and genetics makes work difficult to interpret.
The average IQ of different nationalities is not the same. Research shows that literacy, socioeconomic factors, education and life expectancy all affect IQ. According to statistics and research, Hong Kong people have the highest IQ in the world. The average for them is 108. The lowest average IQ belongs to the people of Equatorial Guinea, around 59.
There are differences between men and women, but research has shown that the average IQ of the two sexes is about the same. Women are better than men in verbal skills. Men are also a little stronger in practical activities. Of course, it should not be forgotten that gender differences are also influenced by the culture, education, environment and experiences of individuals.
The fact is that we can not rely on IQ tests. To measure people’s intelligence, we must consider various and complex factors. IQ tests do not do well in this difficult task. Of course, we can not completely ignore their value, but we should not cite them completely.
The course of our lives is so complex that by measuring intelligence with IQ tests we can not make specific predictions about the future. Many people have high IQs but have not made significant gains in life. The opposite is also true.
Is it possible to increase IQ?
The brain is a complex organ. Scientists still do not know exactly what intelligence, learning and knowledge have to do with each other. A person with a high IQ may have little education or general knowledge. Some have passed all the degrees, but do not have that much intelligence.
A study conducted in 2011 showed that people’s intelligence capacity can decrease or increase during adolescence. Abilities such as concentration or memory are improved, and their improvement also has a positive effect on IQ.
With continuous learning, it will also be possible to improve these abilities:
Understanding new concepts;
Studying fiction and non-fiction books, solving puzzles, attending group discussion sessions, and learning music are ways to increase IQ.
People with higher IQs make better decisions in complex life situations. High brain capacity can be a factor in achieving many successes in personal and professional life. Even if one does not have a high IQ, one should not think that one can not succeed. A low IQ should not be a reason not to move in the right direction. There is always the opportunity for everyone to learn.
There is no specific relationship between achievement and IQ. We can not predict anything about fate and life. So regardless of criteria such as IQ, we must be constantly learning and trying to gain new experiences.
