Korean and Chinese IQ distributions were far below the American IQ distribution. They had the political will to change that. That's the point.
The idea of national mappings of "IQ distributions" are mostly fictitious. Nobody has ever run even plausibly-powered surveys to establish such a thing. Most people reading this thread have never even been offered a proctored IQ test, let alone been requested to take one to help establish an American national IQ statistic.
From what I understand, a reliable "America vs. China" IQ comparison is mostly hopeless.
