Are there brain diferences between STEM people and humanities people?
It would be possible to test children preferences like a personality test so the children only studies what he's naturally talented at?
Like asian kids being trained since children to be STEM robots while hispanics become trade people and blacks become artists or sport guys.
Is this even possible?
I mean, why should we force an education over topics we're not naturally talented or don't want.
Most studies show that inteligence is largely genetic, and also that there are several kinds of "intelligences" i.e. artistic, logic, geometric, musical etc.
So, yes, what you propose could be possible and has been considered by several people when designing our education system. However, it is unlikely that it is connected directly to race
yes people from STEM are dumber as they lack the abilities of pattern recognition needed to formulate a sociological thesis
