Whether there are meaningful genetic variations in intelligence (the subtext of these discussions is always intelligence) that break down in any scientifically valid way along "racial" lines is very much in doubt. What we have is evidence of (socioculturally-sense) racial disparities in psychometric tests in a limited number of (largely western) countries. We don't have causality, we don't have wide surveys globally, we don't even have that much certainty about the test validity. It's equally plausible that the variations we see are SES and cultural transmission effects.
Contra claims elsewhere on this thread, science on this topic isn't suppressed at all. There are multiple branches (in quantitative psychology and genetics) that study this issue actively, and if you follow it, new papers aren't rare. But directionally those papers aren't confirming the priors of the people claiming the science is suppressed, so they don't get acknowledged.
