What is IQ _ IQ detailed introduction

What is IQ _ IQ Introduction Previous: How to improve your IQ Next: What is IQ _ IQ Introduction What is IQ? IQ, or IQ, was invented by Binet.Alfred. Alfred, a Frenchman, includes observation, memory, imagination, analysis and judgment, thinking and adaptability. Let me tell you something about IQ.

?

First, the basic concept of IQ

IQ is IQ (abbreviation of IQ), that is, IQ, which specifically refers to the ability of numbers, space, logic, vocabulary, memory and so on. The so-called wisdom and cleverness. It is the ability of people to know objective things and use knowledge to solve practical problems. The level of intelligence is usually expressed by IQ, which is used to express the level of intellectual development.

IQ was invented by Binet.Alfred, a Frenchman. Alfred (1857-1911) and his students. According to the results of this test, the average IQ of ordinary people is set at 100, while the IQ of normal people is mostly between 85-65438.

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 window XP, 386 and 486 can only run small software such as DOS.

Second, the IQ classification

1, specific IQ

It was invented by Binet.Alfred, a Frenchman. Alfred (1857-1911) and his students, according to the results of this test, set the average IQ of ordinary people at 100, while the IQ of normal people, according to this test, is mostly between 85 and 65438.

The formula is IQ = 100? Master/master

MA = mental age

CA = physiological age

If a person's intellectual age is equal to his actual age, then his IQ is 100, indicating that his intelligence is medium.

2. Deviation IQ

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

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 the latter. At present, most intelligence measurements use biased IQ to represent a person's intelligence level.

The formula is IQ =100+15z =100+15 (x-m)/s.

Z = standard score

X = someone's actual score in the test.

M = the average score people get in the test.

S = standard deviation of the scores of this group.

If the average score of 1000 random testers in the test is 20, and the standard standard deviation of the score of the reorganized population is 4, then the IQ of a person with a score of 28 is 100+ 15? (28-20)/4= 130

Five uses of IQ

The use of IQ 1. check

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.

The use of IQ II. chinese chess

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.

The use of IQ three. scientific research

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.

The use of IQ IV. politics

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 survey by a British scientist, 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, and their average IQ is about 100. ..... and the IQ of African blacks is around 80.

However, this scientist was later exposed to racial discrimination, and the selected data was subjective, so his research may not be credible, but it can also be seen that 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.

The use of IQ and economy

After talking about politics, let's take a look at the economic circle. We 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, the founder of Ford Motor Company? Ford. 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 first. When the reporter asked, "How did you get to this point and become a richer person than God?" Buffett replied, "It's easy to say how I got here.

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. "
