Why are the ethnic groups with the highest IQ in the United States Chinese?

China people mainly talk about the deviation of sample selection. Because the average educational level and IQ of China people who go abroad are higher than the domestic average, for example, they go to a good university to study undergraduate, doctoral and do advanced technical work. Then, because China's basic education is more powerful in mathematics and other sciences, it will appear to have a high IQ (think about it, Americans are confused when they look at the formula, and China will finish it in five minutes. How does it feel? )。 Therefore, among college students and white-collar workers in the United States, the impression that "China people are good at math" has been left, and these American college students and white-collar workers will be the mainstay of the future society, so China people are good at math-> The impression of higher IQ is also common in American society.

Moreover, many universities will do some psychological experiments, and the results of these experiments are often aimed at college students. Based on the above reasons, college students in China generally perform well in IQ tests that attach importance to logical and mathematical abilities, so the continuous publication of these research results also proves that "China people have high IQ" from a "scientific" perspective.

But not all China people have high IQ. Generally speaking, when Americans see handyman and hotel waiter in Chinatown, they don't get the impression of high IQ, but when they meet a China person in college, they usually get this impression. This also shows that the main area of China people's high IQ lies in the upper-middle class, not in the lower-class workers.

What Jews say is that their family culture pays more attention to education and intellectual development. They are relatively rich and have good family conditions (family economic conditions are closely related to intellectual development), so compared with ordinary Americans, people cultivated by this family culture will be more "smart" or pay more attention to "wisdom".

If you immigrate to the second generation, because the parents of the first generation pay more attention to education and intellectual education, the second generation will still have some advantages, not to mention further.

I hope to adopt O (∩ _ ∩) O. Thank you.
