IQ tests are biased towards white populations. Made for and by white people, testing constructs white people are familiar with. There is a small but significant difference there.
Furthermore, the IQ scores of previously oppressed cultures, such as African Americans, are growing at a much FASTER pace than white IQ scores. The gap is narrowing, and it is because the environmental influence on IQ is huge (there is genetic heritability too). So over the last decades Black Americans have been given access to forums they were previously excluded from and what happens? The IQ gap narrows.
There is PLENTY of RECENT scientific evidence that proves this. Just have Google. (Google Scholar that is)
This is absolutely not true.
I do not agree that the tests are biased towards Whites, but that is not a scientific question. I am acquaintances with some of the top IQ scholars on Earth, and they do not agree with you on that one.
Furthermore, even the IQ scholars on the Left who feel that the difference is environmental and that Blacks can make up the gap no longer believe that the tests are biased towards Whites. All reputable IQ scholars now agree that the tests are not biased against Black people. This is an old belief by people outside the field who are ignorant of recent consensus in the field.
If you refer to the Flynn Effect, all groups are going up in tandem. The Blacks are not really growing faster than the Whites. It is possible that the scores of Black adults have narrowed the gap by 2 IQ points over 30 years, but I had to do a lot of fancy stuff with statistics including throw out some tests I did not like in order to get that result.
The gap has narrowed much more for Black children who have narrowed the gap by 5.5 points over 30 years. That figure is fairly uncontroversial. However that gain tends to crash back down as Blacks move out of childhood and many of the gains of Black children are lost.
