How does a person's IQ develop?

Human intelligence is evolving, and the speed of human intelligence evolution is different in different places.

Human intelligence, if replaced by another word, is probably more appropriate to use IQ.

The evolution of biology is like this. What is needed will evolve, which is determined by natural selection. So is human evolution. What behavior is conducive to survival, what behavior evolved.

In an uncivilized society, the evolution of human intelligence is very slow and may even stagnate. Under a certain social situation, there is a limit to a certain character and evolution of human beings. That is, as long as this social situation remains unchanged, this trait of human beings will not continue to evolve. Therefore, in an uncivilized society, human intelligence will also evolve, and this evolution will also evolve with the changes of uncivilized society. The development of uncivilized society is different and changing, but the change is very slow. The change of uncivilized society is slow, so is the change of human intelligence. This intellectual change can refer to both progress and retrogression. It's just that many times, an uncivilized society is easier to make progress. Therefore, human intelligence is generally advancing in an uncivilized society.

After entering civilized society, human intelligence began to evolve rapidly. Because, when you need more brains, you need more intelligence, and intelligence naturally evolves faster. However, intelligence will also stagnate or even regress in civilized society. This mainly depends on whether a civilized society is progressing, stagnant or even retrogressive. One more function and one more burden. One more function, one more ability. One more ability, one more viability. The evolution of a function will stagnate at this time, that is, the disadvantages will be as long as the benefits. Of course, some functions can replace each other, and humans also use their limited bodies to install more functions. The evolution of mankind is to move towards the high efficiency of various functions and the best combination of various functions. Intelligence is an important function of human beings, and it must be coordinated with other functions of the human body in order to realize its due benefits. Everything has gone too far. Including intelligence. When the state of social development is certain, the intelligence needed by such a society also has a good average. Generally speaking, in such a society, it is generally most possible for intelligence to develop to this extent. However, it is difficult for the society to be stable in a certain state for a long time, and it will generally move forward. Therefore, human intelligence is constantly changing. Different places, due to different natural conditions, the social performance is bound to be different, even if the technology is similar, the social performance is also different. Therefore, natural conditions affect all human societies and, of course, human intelligence. Natural conditions vary from place to place, so the intellectual development of human beings is influenced by natural conditions in different degrees. So natural conditions also affect people's intelligence.

In a society that needs intelligence, the development of human intelligence is bound to be faster. The greater the demand, the faster the development of intelligence. Of course, in a certain social situation, intelligence will develop to a certain limit. In other words, in a society that needs intelligence, people's IQ is higher. In a society that doesn't need intelligence much, people's IQ is even lower. Therefore, according to this truth, you can judge the possible IQ of people in all parts of the world. Those are ancient, (for example, 200 years ago, or even ancient. ) In areas that have never entered a civilized society, the indigenous people in this area are non-immigrants. ) IQ is inevitably not high, and it should be the group with the lowest IQ in the world. Like African dwarfs. For example, before 100 years ago, those areas with low social civilization didn't even have local characters. Although there are also countries or political organizations. The IQ of people in these areas is also surprisingly low. I estimate that most African blacks belong to this group. Hundreds of years ago, I didn't create my own words. Pure Indians probably belong to this group. The aborigines of Southeast Asian islands also belong to this group.

The areas with relatively high IQ are those areas that once had splendid ancient civilization and had their own characters for a long time. However, in the past 1000 years, the level of civilization was relatively dim. Or, a place where civilization is stagnant. People in this place have average IQ. For example, South Asians, West Asians and North Africans. It's probably all because of religion. People's intellectual development has also stagnated or even regressed. Perhaps, thousands of years ago, the ancients here had higher IQ than the people here now.

The birthplace of modern civilization is people with high IQ. Because, in the past 500 years, their IQ has been slowly improving. There is a 500-year IQ improvement period. The IQ here was stagnant 60 years ago. Sixty years ago, it was a turning point in the stagnation of global IQ development. Sixty years ago, the IQ of the whole human race stopped moving forward.

The major ethnic groups in East Asia have a long history of civilization. Rich in culture. People's IQ is very important in ancient times, because you can be the first, so the emergence of science and technology system is of great value to the improvement of IQ of East Asians. Knowledge is very important among East Asians. Knowledge can change fate. So the IQ of people here has evolved faster. Up to now, people here have high IQs. It is the region with the highest human IQ. (In fact, the world of 300 years can greatly change the IQ of people in a certain area. )

People's work objects have a great influence on IQ. The most common modes of labor are nomadism and farming. Animal husbandry is different from nomadic industry. ) the intelligence required by nomadism is relatively low, and it is not as high as that required by farming. In agricultural areas, herding sheep is a matter for children. Therefore, the IQ of people who evolved from these two agricultural models will be very different. The IQ of people in agricultural areas is relatively higher than that in nomadic areas. In fact, nomadism and farming can still be subdivided. Nomadic in cold regions is relatively more complicated and difficult than nomadic in tropical regions. Moreover, living in cold areas also requires more knowledge, which may be more important. This requires a higher IQ. Therefore, the IQ of nomadic people in cold regions is higher than that of nomadic people in tropical regions. Then, the farming population can also be classified in this way. The IQ of temperate farming peoples is higher than that of tropical farming peoples. Because temperature agriculture is relatively more complicated, and the survival of temperate people is relatively more difficult than that of tropical people. Hard environment can improve people's IQ. Because of the high IQ requirements.

Another possible reason why people in agricultural areas have higher IQ than those in nomadic areas is that businesses in agricultural areas are relatively developed (the business population includes both businessmen and institutional goods). ) The commercial population is also larger than that in nomadic areas. This is very important. The IQ requirements for business people are relatively high. Therefore, the increase in the proportion of commercial population is conducive to the improvement of the average IQ of the whole population. This should be one reason why the IQ of people in agricultural areas is higher than that in nomadic areas.

Of course, the main reason why people in agricultural areas have higher IQ than those in nomadic areas may be the different importance of science, technology and culture. In agricultural areas, a certain proportion of people live by knowledge. And IQ is very important to have knowledge. Therefore, this phenomenon is very valuable for improving the IQ of people in rural areas.

Of course, human beings also have other industries, or survival modes. For example, those who fish may need more intelligence than nomads.

For people who live in a certain area for a long time, people will have as much intelligence as society needs, which is realized through the evolution of intelligence. Individuals are forced to adapt to this society. Otherwise it will be eliminated. Of course, people's intelligence is determined by heredity, and people with unsuitable intelligence will be gradually eliminated. For a certain social state, the higher the intelligence, the better, but the higher the comprehensive viability. Since it is a comprehensive ability, then human beings must attend to one thing and lose sight of another, and the human body is limited. The appearance of one advantage means the disappearance of another advantage. What matters is the best combination. Human evolution is moving in this direction.

However, 60 years ago, mankind entered a new era. Human evolution can be said to have completely stopped. The reason is that personal survival pressure is not great. What kind of people can survive, they can live well. Humans have lost the motivation of evolution. The average IQ, the average quality of human beings, has become meaningless. Mankind is moving in all directions of differentiation. Such as polarization. People with high IQ can live well, and people with low IQ can live well. People with developed functions can live, and human society no longer has the function of directional choice. Humans may enter an era of differentiation of various traits, although on the surface, all races in the world are more integrated. This means that human beings in the future will be more complicated.
