Well, it is actually quite complicated. Can't write it all. Let me talk about a few simple places first. It would be nice if you could do the experiment by yourself, but I guess you don't have time.

First, under certain constraints, such as age, the more you know, the worse your creativity is. People will naturally become inert because their needs are met. The demand here is often the desire to learn or explore. For a simple example, the remote control was originally designed for the convenience of the elderly queen with mobility difficulties. After the promotion, it has had a great impact on the TV industry. At least, so far, TV in daily life has not jumped out of the circle of remote control. Imagine, on the contrary, how could TV develop without this thing at first? We will certainly have other equally convenient or more convenient devices to change channels. This is the performance of manufacturing constraints, and remote control is the reason.

Second, although the United States is also taking compulsory education, giving students a high degree of freedom of choice means that students can consciously realize the choice of elite education. So we have a lot of average time, but if we measure the time students spend studying, students in the United States are distributed in a large range of time, while students in China may be concentrated in places where they spend a lot of time studying every day.

Third, computing ability ... To be honest, after training, everyone is similar, the only difference is the time and cost of training.

I hope my nonsense will help you.
