Even if that were true, that would mean their average IQ is at least 20 points above yours. All this genetic and racist content you post is total crap.
It's culture, or the lack of it. Today 70%+ of black woman give birth to a fatherless child. That is a terrible statistic. I posted this earlier. If Nigerians can do it, there is no excuse for American blacks, or any other race, for that matter. https://www.ozy.com/around-the-worl...hnic-group-in-the-u-s-may-surprise-you/86885/
Selective breeding has been proven to work, it has been used to enhance milk production in cows, increase muscle mass and make larger chickens... Also your hero Odumbo is living proof it works in Humans. A 100% regular Black would never have made it to the top job. Even Joe Biden said: "I mean, you got the first mainstream African-American who is articulate and bright and clean and a nice-looking guy. I mean, that's a storybook, man." Why did Obama have those traits that Biden said were rare amongst Blacks? So selective breeding should be voluntarily encouraged amongst humans to solve Black crime and Black unemployment levels. Of course political correctness will stop it from even being discussed let alone encouraged.
