We care about racial differences in outcomes that are correlated to IQ, such as employment and imprisonment.
What if some of the observed racial differences were caused by a lack of vitimin D, due to darker skin photosynthesising less of it? Then we could fix the prison crisis with a pill!
If we block all research into a problem then we can’t solve it.
If you actually care about fixing a problem then we should bring all available tools to fix and solve it.

Correlation measures whether Y=mX+c holds with small error. I sometimes think that many people unknowingly assume that all dependencies are somehow straight-line ones. This is distinct however from "linear approximations" in physics, which can at least be justified sometimes.
I also suspect that correlations of 0.5 or lower are often just statistical noise.
