If you ever had a conversation with a "smart" Negro like I have you will find they have in fact studied something but they still have a different thinking process and are not at all able to add to anything which would account for why so few patents are credited to them. They are dangerous to have in charge of something because they still despite some academic success draw flawed conclusions about things and every chance they get will act against Whites. Also brainpower has to be translated into some kind of physical act of putting something into place, that is making something happen and it soon becomes apparent that Negros are not very good at doing that. It could be anything - visualizing how something needs to look or function or some kind of coordination that Negros just simply do not possess. The vast majority of Negros who are rated as being good at something actually are not if you look closely at what they do. Other races fall somewhere between Whites and Blacks and usually closer to Black performance than Whites.
