I would like to point out that within this comment you argue quite correctly that averages of groups should not be extrapolated to the entire group. However in most of your argument you propose that companies and societies will extrapolate IQ research to the group and discriminate on those bases.
Now I'm not saying anything about your personal views about the research, but I think in order to fix the cultural and societal discrimination you touch upon we should emphasize exactly the reasoning you expounded about the nuance of averages. We know that there is more differences within groups than between them and I think to deter the effects of discrimination we need to emphasize analysis on the individual level and to have a real and honest discussion about the issues and to make statistical reasoning more prevalent among the general population.
