『____The average IQ of each age group. What is the difference? . ?

Professor Lin En began to study the field of racial IQ in 1977. He said in the letter that in the 1970s, he noticed the rapid development of Japan. As an IQ research expert, he immediately thought, is Japan able to develop so quickly because they have a high IQ? So, he began an investigation of Japanese IQ tests. He found that the average IQ of Japanese people reached 105. After coming to this conclusion, he also wondered whether the Chinese should also have the same high IQ? The results of the survey and test showed that his idea was right, and the average IQ of the Chinese people reached 105.

China and Japan both belong to the Mongol race and are very close geographically. Therefore, Professor Lin En began to study the differences in IQ between races. After collecting and studying IQ tests from 130 countries, Professor Lin En summarized the differences in IQ rankings among races in different regions and the reasons.

East Asians (including Chinese, Japanese, and Koreans) have the highest average IQ in the world, with an average of 105. The following rankings are Europeans (100), Eskimos (91), Southeast Asians (87), Native American Indians (87), indigenous peoples of the Pacific Islands (85), South Asians and North Africans (84), Saharan Africa People (67), Australian Aboriginals (62). The areas with the lowest racial IQ are the jungle people in the desert plateau of South Africa and the pygmies in the Congo rain forest, with an average IQ of 54.

Lynn’s research has been criticized by Western society. He said that because there is a view in the West that the IQ of all races is the same, studying the differences in IQ between races is considered racial discrimination.

Through research, Linn believes that it is the harsh living environment that creates a race of highly intelligent people.

Professor Lin En also conducted research on the reasons for this conclusion. He believes that the reasons for the differences in IQ between races are the living environment and genes. Professor Lin first noticed the views of Jellison, an expert on brain evolution at the University of California: In the process of species evolution, the intelligence evolution of species has been greatly affected by the environment, and is also an important factor in natural selection. If animals want to become survivors in harsh environments, they must evolve a large enough brain capacity so that the information they sense through vision, hearing and smell can be fully analyzed in the brain.

Professor Lin En believes that this theory can also be applied to human evolution. After analyzing a lot of data, Professor Lin En concluded that the cold climate gave humans greater brain capacity. For example, the average brain capacity of East Asians is 1416cc, that of Europeans is 1367cc, and that of Saharan Africans is 1282cc. Professor Linn said that the cold climate required early humans to learn how to keep out the cold. In winter, when there is no grass growing and few animals appear, the search for food and efforts to survive have enabled humans in these areas to gain higher and higher IQs in order not to be eliminated by nature.

Since East Asians have the highest IQ, why are Westerners better than Easterners in inventions and creations?

When Professor Linn proposed his research, many people raised doubts. The first point is that although East Asians have higher IQs than Europeans and Americans, Europeans are superior to East Asians in scientific and technological research and have invented more. Professor Lin believes that this is because East Asians are more conventional in character than Europeans, so their inventions and creations have been affected to a certain extent, but this does not prove that East Asians have lower IQs than Europeans.

Professor Lin En also pointed out that smart East Asians are now spread all over the world, including Singapore, Malaysia, Hawaii, and North America. And their participation and achievements in various scientific fields are becoming more and more prominent.

The Eskimos live in a world of ice and snow, but why don’t they have the highest IQ?

Another question some European scholars have about Professor Linn’s conclusion is that since the cold climate has allowed humans to evolve the largest brain capacity and acquire high IQ, why are the Eskimos living in the ice and snow? exception.

Professor Lin used genetic mutation to explain this problem. Professor Linn said that when early African Homo erectus evolved and migrated to various parts of the world, they carried genes that could evolve high and low IQs. And this kind of gene has more chances to evolve in areas with rapid population development and large populations. In the cold season, humans with low IQs are gradually eliminated, while those with high IQs become the survivors.

The Eskimos have a sparse population, and the chance of the gene that controls IQ mutating into a high IQ is smaller than that of the Eurasians. To this day, the total population of Eskimos is only 55,000.

How do we get the high IQ value of Chinese people?

The testing and summary of racial IQ is a very complex and huge project. In Professor Lin's research, the IQ tests of people in 130 countries came from various professional IQ survey organizations. For example, regarding China's ethnic IQ test, people of different age groups in Beijing, Shanghai, Hong Kong, Tibet and other regions have received standardized intelligence test surveys. Test questions include the Children's Intelligence Scale-Revised and Raven's Standard Reasoning Test. After conducting complex table processing and calculations, the current conclusion is reached.

The data included include the Children's Intelligence Scale test conducted in Shanghai in the mid-1990s, which yielded a per capita IQ value of 107, and several other IQ test questions for adolescents aged 14 to 15 years old. has an IQ value of 103. There is also a test conducted on Chinese teenagers aged 6 to 15 through the Raven Standard Reasoning Test (non-verbal IQ test questions), with an average score of 101, an average score of 104 for 12 to 18 years old, and so on.

■Knowledge Tips What is IQ? How to test?

Although we often use the term IQ to describe how smart a person is, I am afraid that few people can accurately tell what this term means and how to test it. Therefore, our reporter also asked Professor Lin En to give us an explanation, and Professor Lin En provided us with some information.

IQ (English intelligence quotient, referred to as IQ) can be understood colloquially as intelligence, which refers to numerical, spatial, logical, vocabulary, creativity, memory and other abilities. The simplest way to measure intelligence is to give a test, and the questions in the test clearly reflect the application of the above abilities.

In 1905, French psychologist Binet and educator Simon collaborated to design the world's first intelligence test. Each of these tests has 30 questions, ranging from easy to deep, testing people's judgment, understanding and logic abilities. This test was adopted by the French government at the time to test the intelligence of school children in order to identify those with lower intelligence and provide them with special education services. This test was named the Binet-Simon Intelligence Scale, and subsequent revisions to previously designed tests were continued. After searching for other information, the reporter found that in the early 1920s and 1930s, China's Lu Zhiwei, Liao Shicheng, and Chen Heqin revised the test questions.

In 1916, psychologist Stern proposed the concept of "IQ": If a child's intellectual age is the same as his biological age, then his intelligence is average; If the mental age is higher or lower than his biological age, his intelligence is above or below the average level.
