Plus, why wasn't the original title "IQ and the Wealth of Nations" preserved over a much less representing while much more link-baiting one "China has a higher average IQ than the USA"?
So, assuming each country also has the same shape of distribution but different averages, a difference of 15 points means that an average person in the "smart" country is smarter than 83% of the people in the other country. An average IQ difference of 30 points would be more like 98%.
Which, to me, seems like a pretty extreme difference. Without knowing more about their methodology I don't know if I trust these numbers much. On the other hand, looking at the countries at the lower end, I wouldn't be surprised if a lot of the difference was due to environmental factors such as poor nutrition.
Unfortunately, IQ is a field of study that's far too politically charged for there to be much in the way of reputable research.
Chinese has this kind of amazing potential, but I don't see a good way we can we exploit it.
The other major part being a collectivist, conformist culture isn't something that breeds creativity. China's most creative people either leave for the USA or rot in China.
Creativity is important, but perhaps political, or maybe "societal", advantages (freedom of expression etc), are no less important. For example, Russia, where I am from, has had plenty of creative people, but it is still behind in many ways. What I can see is that in different societies creative people apply their talents to achieving different goals.
