@shortstories Disagree, I don't think humanity's biggest issue is a lack of intelligence, but rather too much collectivism and weakness.
Intelligent people aren't underpopulated, but weak people are overpopulated and the two groups aren't mutually exclusive at all.
Everyone thinks they're way smarter than the average person and the world is plagued by idiocy, yet they follow the group instinctively. You can increase their brain power all you want, their instinct is hard coded.
Confucianism is a entire worldview about following other people
China is or was the largest country in the world by population
China is Confucianist
I suspect Chinese IQ test results are rigged
Maybe since they have such a high population they hand pick the subjects who take the tests to rig the results if a third party is testing the people
Maybe they just make up numbers if there is no third party
There is a cultural reason for that
In ancient China people were selected for Government positions based on how well they did on tests
This would create a culture of studying to do well on tests in China, Japan and North and South Korea
This did not create a culture of inventing new things
But of memorizing old things for social status
So it could not help them develop better weapons
Europe developed better weapons and invaded Asian countries to force trade
