According to these studies it is very clear that human races differ not only in physical aspect but in intelligence also. It is also clear that IQ is something attributed to people by their genes and it can not be altered through culture or education. Asians and white Caucasians are the smartest human races on earth. From the following chart it is also very clear that IQ has decreased in Europe from 2002 to 2006 together with non-white immigrants into Europe, particularly Arabs and Africans.
IQ isn’t something you learn in school. You are born with it, you die with it. You can’t become Einstein or Tesla by studying. Culture and education are irrelevant to IQ. Geniuses are born geniuses, they don’t become geniuses by reading books, going to school, etc. In response to the egalitarians, there is no one stopping Africans from building schools in their own nations, nor is it the duty of the white people to build schools for them. No one ever gave anything to Europeans for free. So why Africans should ever receive something from Europeans?
