How high is a person's IQ

IQ is IQ. Cleverness is usually called wisdom, also called cleverness. It is the ability of people to know objective things and use knowledge to solve practical problems. Intelligence includes many aspects, such as observation, memory, imagination, analysis and judgment, thinking ability, adaptability and so on. The level of intelligence is usually expressed by IQ, which is used to express the level of intellectual development.

1905, French psychologists formulated the first scale for measuring intelligence-Binet-Simon Intelligence Scale, which was introduced to China in 1922 and revised by Mr. Wu in Beijing in 1982. It has ***5 1 question, and is mainly suitable for measurement. 19 16 wexler compiled Wexler Adult Intelligence Scale (WAIS), Children Intelligence Scale (WISC) and wexler Infant Intelligence Scale (WPPSZ) for children aged 4-6.5 years. Wechsler scale was introduced into China in the middle and late 1980s, and was revised and published in Chinese, so it was widely used.

There are two kinds of IQ, one is the ratio IQ, and the age of intelligence is equal to the age of foot. If a person's intellectual age is equal to his actual age, then his IQ is 100, indicating that his intelligence is medium. The other is biased IQ, which takes the ratio of a person's test scores to the average intelligence of normal people of the same age as IQ. Nowadays, most intelligence tests use wandering IQ.

In order to accurately express a person's intelligence level, intelligence measurement experts put forward the concept of deviation IQ, that is, measuring a person's correct position in his age, that is, by calculating how many standard deviations the subjects deviate from the average, which is called deviation IQ, also known as IQ.

(2) For example, for two adults of different ages, one person's intelligence measurement score is higher than the average score of the same age group, and the other person's test score is lower than the average score of the same age group, then we can draw the conclusion that the IQ of the former is higher than that of the latter.

(3) At present, most of the intelligence measurements use biased IQ to express a person's intelligence level.

④ Distribution of population IQ.

In a typical modern intelligence test, if the average IQ of the subject population is 100, according to certain statistical principles, the IQ of half the population is between 90- 1 10, and the IQ is between 90- 100 and 165438+. 1 10- 120 accounted for 14.5%, 120- 130 accounted for 7%,130-10.

⑤ Extraordinary intelligence and low intelligence.

After the appearance of intelligence test, it becomes easier to distinguish intelligence differences. It is found that a few people have extremely high IQ (above 130) and extremely low IQ (below 70), and about 80% of the total population have average or near-average IQ (between 80- 120). Those with higher intelligence than normal are called abnormal intelligence, while those with lower intelligence are called abnormal intelligence.

We adopted the intelligence scale compiled by American psychologist wexler and revised by Gong Yaoxian of Hunan Medical University, and formulated the China norm. Now we can test children aged 6- 16 and adults aged 16. Through psychological measurement, we can understand our intelligence level and potential, identify the intellectual damage caused by traffic accidents, and provide scientific basis for giving full play to our advantages, filling in the college entrance examination volunteers scientifically and giving birth to excellent children.

The IQ test includes 1 1 items, including common sense, understanding, arithmetic, similarity, memory, words, images, building blocks, permutation, puzzles and symbols. The whole test takes about an hour, and it takes about an hour to summarize, analyze and write a test report.

IQ is IQ (short for IQ). Generally speaking, it can be understood as intelligence, specifically referring to the ability of numbers, space, logic, vocabulary, memory and so on. In a sense, IQ is like computer hardware such as CPU. A person with high IQ can do very complicated things in a short time. Just as Pentium and Centrino CPU can run large software such as Windows XP, 386 and 486 can only run small software such as DOS.

During our study at school, we will spend a lot of time on IQ training besides learning knowledge. Learn mathematics to exercise numerical calculation, spatial imagination, logical reasoning ability, and exercise vocabulary and memory ability with Chinese, English, history and geography. The college entrance examination can be said to be a great review of people's abilities in these aspects.

Because the examination is conducted in a limited time, people are required to have high memory and processing ability for complex information in a short time. Therefore, people with high IQ have a special advantage in exams. We all think that if a person has a good memory, it is something that everyone envies. Because a large part of the content of most exams is something that needs to be firmly remembered. Therefore, for candidates, a good memory is the basis of high scores. If you have a good memory, good computing skills and good language skills, you can get into a good university if you work harder.

For most people, the use of IQ ends here. Why do you say that? Because in real social life, the use of high IQ is very limited. Only a few fields need high IQ. Chess, for example, requires higher IQ. However, their demand for IQ is not insignificant. According to the test of psychology department of East China Normal University, Chang Hao, one of the best chess players in China, has an IQ of 138, while Li Changgao, who is known as the first person in the world, has an IQ of 139. Their IQ is excellent, but they don't reach the level of genius (generally speaking, they are geniuses with IQ greater than 140). It seems that even the most intelligent chess game needs enough IQ, not too high.

Another area that seems to require a high IQ is scientific research. However, I believe that the requirements for IQ in this field will not be outrageous, at least it will not exceed the IQ required by chess players. So, is there a bottom line for IQ in scientific research?

This question seems to be inconclusive, and some researchers can refer to it. Zhang Guanghou, a famous mathematician in China, was not outstanding in intelligence when he was studying in primary and middle schools. He said: "You don't need to be too smart to do math, but you can have a moderate talent, mainly perseverance and hard work." Darwin once said: "The most important reason why I can succeed in science is my love for science, my persistence in long-term exploration, my exploration of observation and my diligence in my career." Weiner, the founder of modern cybernetics and a great mathematician, said in his autobiography that three or four people who were also called prodigies in his childhood did nothing when they grew up because they were not diligent and other conditions. On the contrary, some people are ordinary when they are young, but due to their later diligence and environmental influence, they eventually become great men in the history of science and technology.

I don't know if anyone has done such a study, which is to list the IQ bottom line required by all walks of life. I think, if there is such a bottom line, the requirements of players should be the highest, and they may not be able to do it without excellent level. And what about people who do scientific research? I think the medium level will do.

So, what is the situation outside these two regions? I think most industries should have no special requirements for IQ, as long as they reach the passing level.

Let's talk about the political industry first. In America, you don't need a high IQ to be president. For example, George W. Bush is often ridiculed for his low IQ. According to a study by Austin College in Tam, Pennsylvania, his IQ is 9 1. Old Bush is only a little taller than him, 98 years old.

What are the concepts of IQ 9 1 and 98? According to a statistic made by British and Finnish scientists, the people with the highest IQ in the world are nationals of China, Singapore, South Korea and Japan, and their average IQ is as high as 105. Secondly, smart people are distributed in Europe, North America, Australia and New Zealand, with an average IQ of 100. In other words, the IQ of George W. Bush and George H. Bush are lower than that of at least half of China and at least half of Americans. It is such a person with low IQ who can still be president and get high support rate. It can be seen that in the United States, at least in the political field, there seems to be no superstition about high IQ, and people value the personal charm of politicians more.

After talking about politics, let's take a look at the economic circle. We can see that many of China's Forbes rich list are primary school graduates, and American rich people also have primary school graduates, such as Henry Ford, the founder of Ford Motor Company. Many college students have heard of Yu, the founder of New Oriental School, but his IQ is not very prominent. He was admitted to the university three times that year.

Perhaps we can have a deeper understanding of this issue by watching the dialogue of Buffett, the world's richest man. Among the 200 billionaires in the world recently published by Forbes magazine, Warren Buffett ranks third. When the reporter asked, "How did you get to this point and become a richer person than God?" Buffett replied:

How I got here is easy to say. My success is not due to my high IQ. I'm sure you'll be happy to hear that. I think the most important thing is rationality. I have always regarded wisdom and talent as the horsepower of the engine, but the output power, that is, the working efficiency of the engine, depends on rationality. So, why don't some smart people get the results they deserve? This involves habits, personality, temperament and other factors, whether your behavior is rational or not, and whether you are obstructing yourself. As I said, everyone here is fully capable of doing anything I do, even much more than me.
