I had an argument with a guy (over internet) where he claimed that black people are the least intelligent race compared to caucasians and asians. I of course was saying that he is just being racist and should shut the hell up and was explaining the poor condition of african nations with colonialism, racism and all that stuff. However i realized that there is actually no evidence (at least anything im aware of) proving that black people are equal with white or asian people in terms of intelligence.
Even if we humans think that everything should be fair, that's not how evolution works. There is no reason to assume that people who are geographically separated should evolve the same way intellectually. There is difference between the musculature of black and white, for example, so it's possible that also brain evolved differently because of different natural selection and/or chance.
However there is some evidence which indicates that black people are less intelligent.
We can look at african nations today and world's history. Whites came up with most, if not all, relevant modern inventions (eg. electricity, gun powder), they conquered the globe and dominated everyone else for few centuries. While african countries even today are still poor while China, for instance, which was european-dominated in the past will probably be the biggest superpower in the near future. South-Africa, which is led by whites, is one of the few developed countries in Africa (if we ignore the human-right violations).
Even the "black" areas in the rich developed countries are worse than that. Blacks also continously score lower IQ points in tests even if they were born in USA or Europe.
Im not saying that we are stupider than whites because i dont want to believe in it (yet) but is there actually any other reasonable explanation to all this? Only explanation ive found anywhere has been smth along the lines of:
"Stfu you racist ashhole everyones equal because god gave everyone the same intelligence !!!" People dont want to discuss about this rationally because there is always emotional outbursts so if anyone is willing to discuss about this try to keep it rational.
