It is much more complex.... like you said.
For example,... if the East Asian IQ is highest, why did the Japanese/Chinese not industrialize before the west, for example..?
Seems like an obvious assumption, right?
It's an incorrect one however.
This is referring to average IQ. When the average IQ is higher generally, production does not increase (they are all too busy thinking, , to do any work..or something..lol)
Lower IQ's can mean higher industrial output..
It is not an answer, or a panacea to the worlds ill's - it's a tool to see reality clearer.
There is certainly no 'ego IQ' battle, and there's room for everyone...Everyone has as much value as anyone else.
But to not use the closest scientific tool we have, to measure intelligence and acknowledge that differences exist in the name of political correctness is just ....well...stupid.
