I don't understand why you're so obsessed with showing certain races are genetically smarter than others. Honestly it seems like a thinly veiled excuse for racism. The thing is, it's really hard to show a feature such as intelligence is genetically geared a certain way. Not only because intelligence is hard to measure anyways (SAT scores are mostly reliant on education, I have no idea why they use it as a measure of intelligence, and IQ isn't really objective and kind of obsolete), but also because even if you do show that, it's really hard to demonstrate that the corelation is because of genetic factors, given all the things that contribute to intelligence and of course the fact that these statistics will only show you that there is a certain correlation on average, it doesn't show that there's a certain genetic factor tied to certain races that increases intelligence and it doesn't change the fact that individual people are very different, so I just don't see the importance of it and the need to fixate on it this much.
As for 50cent's statement, I don't even know why you thought it was necessary to post it here. So what if he thinks that?
