I'm noting with interest the difference between Hong Kong (107) Taiwan(104) and the rest of China (100). I wonder how much of it is explained by generations of the brightest Chinese going to Hong Kong to seek their fortune in the capitalist oasis of China, as well as the Chinese middle-class fleeing communism to Taiwan?

"I wonder how much of it is explained by generations of the brightest Chinese going to Hong Kong to seek their fortune in the capitalist oasis of China, as well as the Chinese middle-class fleeing communism to Taiwan?"

Probably a good deal. But I'd also venture that much is explained by Hong Kong and Taiwan being modern, urban countries. Think how many country peasants (no offense, eh!) must be included in the mainland China numbers.

Richard Lynn, (Professor Emeritus, University of Ulster) who doesn't care what people think about his research, has said:

"In 1983 I published a paper in Nature showing that the IQ in Japan had increased over the course of the previous half century, a phenomenon now known as the Flynn Effect following the demonstration by Jim Flynn of secular increases in intelligence in number of countries. In 1989 I proposed that the increases in intelligence have been caused by improvements in nutrition. I have also published several papers showing that intelligence is associated with brain size and reaction times."
