I don’t think it’s as genetic as it is cultural.
You put someone with the same genetics in the two different cultures, and they’ll behave according to that culture.
However, it would be much easier to study a black child raised in a WASP culture than the other way around, because of the hate YT racism factor, which again, is part of the black culture.
anyway, I think this group has breeded downward....so have many whites as well....
breeding intelligence down is not what civilization is based on...we're supposed to improve not descend..
