Contrary to "The Bell Curve" findings, a new study published in the April issue of Child Development by researchers at Columbia and Northwestern Universities suggests that poverty and early learning opportunities -- not race -- account for the gap in IQ scores between blacks and whites.
Adjustments for socioeconomic conditions almost completely eliminate differences in IQ scores between black and white children, according to the study's co-investigators. They include Jeanne Brooks-Gunn and Pamela Klebanov of Columbia's Teachers College, and Greg Duncan of the Center for Urban Affairs and Policy Research at Northwestern University.
As in many other studies, the black children in the study had IQ scores a full 15 points lower than their white counterparts. Poverty alone, the researchers found, accounted for 52 percent of that difference, cutting it to 7 points. Controlling for the children's home environment reduced the difference by another 28 percent, to a statistically insignificant 3 points -- in essence, eliminating the gap altogether.
There is a controversy as to whether the US racial gap in IQ scores is diminishing. If that is the case then this may or may not be related to the Flynn effect. Rushton and Jensen argued against expecting the Flynn Effect to narrow the US black-white IQ gap, since they see that gap as mostly genetic in origin, and there is evidence from mathematical analyses that what causes the Flynn effect is different from what causes the black-white gap. Flynn has replied that he never claimed that the Flynn effect has the same causes as the black-white gap, but that it shows that environmental factors can create IQ differences of a magnitude similar to the gap.

So IQ tests are now rejected lol, SAT tests are a close relative of IQ tests and far from rejected as you well know!
Yes, IQ tests are largely rejected. They're completely meaningless.
