White hegemony. It justifies discrimination against Black populations. You have to ask yourself what the intent of these IQ comparison? How does it benefit humanity to say "this "race" (race i snot even biological) is smarter than that one? Why do you think they didn't allow slaves to read at first? Even today, schools where many Black students go to are grossly underfunded, with outdated textbooks, terrible infrastructure, etc. compare to other schools in America. It is all about structural violence and it's maintenance.
