Perhaps the average black IQ is 150. So what? That's not your claim. Your claim is that 'white racism' / white people significantly affect the IQ of black people. This is racism. It's formally called Critical Race Theory. Further, HAVE THE PAPER RETRACTED if you think they are analyzing the wrong data set, because as of right now, the data is correct and ANYONE can go to the link I posted and datamine and find the data for themselves. As for IQ and the Flynn effect, (A) most of IQ is genetic (B) because of the repeated exposure to IQ type testing, IQ scores (not brain function) increased over the last few decades (C) all good evidence suggests that IQ is now in decline - and has been for over a decade. No, Progressive Socialism hurts PEOPLE with low IQ. People. Not colored people. People (mostly white people by the bye). I know, I know, it's really difficult to see the world without seeing it through the lens of Critical Race Theory where evil white people are lowering the IQ score of black people - which they are not. PEOPLE of ANY color who happen to be born with low IQ, end up in a lower socioeconomic bracket. What are you missing here? Even if what you propose is correct, and black people have an average IQ of 90+, so what? That is not the ONLY claim made by the authors. The authors show that regardless of ethnicity, people with high-IQ moved into the middle class. This means that once IQ is controlled for, RACE HAD NO EFFECT. Again, can you read? What are you missing? Are you able to see empirical evidence without attempting to twist it around into some half-arsed race-baiting claim about evil white people? The fact is Critical Race Theory has now been Scientifically proven to be incorrect, if you are a Scientifically minded person, you must align your thinking to the Scientific Evidence and reject Critical Race Theory. But you don't want to do that do you? Why? Because you're emotionally connected to this idea that evil White People are to blame. And, given you're a Progressive Socialist, and given Social Marxism is all the rage on the Left, you'd be giving up a lot more than just a pet theory. So you don't. The SAT suggests that high-IQ blacks move into a higher socioeconomic bracket and then their children are born with a lower IQ due to genetic luck, and move right back down. It's a regression to the mean (no scientific dispute here). The SAT scores of at least four different populations: African, European, E. Asian, Latino. Each with different average IQ scores. The adoption studies showed the SAME EFFECT for yellow, white and black adopted children. Adult IQ returns to the overall population mean. Regression to the mean is true for yellow people and the same is true of white people. The only difference is the normality curved are shifted for each population. Which makes sense given IQ is mostly genetic (not a dispute here, ALL scientists agree with this statement) and different populations of humans have different averages for their IQ scores (again, this is NOT in dispute - E. Asians have an average of 105+, that's a scientific fact). There is NO good evidence that 'white people' via 'white racism' is having ANY effect on the average brain function of black, yellow or other white people. What there is good evidence of is Governmental incompetence (and yes iceaura, GiverMint has employed people of all colors) is doing to the water supply, what it did to sound money, sound education and the environment: destroying it.
