IQ is almost completely genetic. That's why is a racist hate speech and hate crime to say it out loud, because it's demoralizing to the races who don't have the IQ in their Genes, and we need them to try, so we need to maintain the illusion that effort is related to intelligence, or perhaps an alternative path, that you don't need to be intelligent in order to buoy your genes and make the nation or organism to which you are a part dominate the others who have nigger shit skins in them that are negative value in all variations of existence, which is mostly the case for monkeys that only recently became humans, rather than humans who have been humans for the most part for the last eighty thousand years..
