As far as I know this argument is not about whether or not racial differences exist in different measures. Everyone agrees those differences exist. The argument is about whether there is sufficient evidence to support claims for biological causes of those differences over sociological explanations grounded in socio-economic and other environmental differences explained mostly by historical factors. It should be obvious why this argument is important to people, not just because one side of the argument is advancing essentially racist conclusions, but also because some (Murray in particular) use this data to argue against policy interventions intended to address the historical causes of racial inequality.
There is, in fact, ample evidence for the importance of environmental explanations of these differences. See for example this
2017 report on educational attainment gaps from the Stanford Center on Poverty and Inequality, as just one example among many. The amount of evidence arguing for the importance of environmental factors is overwhelming. Meanwhile, the evidence for biology is much weaker.
Even in the Bell Curve data, IQ (used as a proxy for biology, which is also somewhat problematic) differences only explain 5-10% of the variance in actual outcomes (cf.
Inequality By Design). Other research aimed at correlating socioeconomic outcomes to differences in intelligence have had similar results, with respect to explained variance. So, even in the data that is supposed to be making a strong case for a "genotocracy", what is evident is that environmental factors play a much larger role. Even if we assume that GWAS methodologies and other improvements in genetics research will lead to an increase in the %-variance explained by these studies (I think this is likely when comparing individuals), it's quite unreasonable to conclude -- in the face of so much evidence -- that somehow biology trumps environment.
