I have been saying approximately this for decades,  although with less expansive arguments and based more on just logic than on the research at the disposal of this writer.  I thought it was wildly unlikely that the only average differences among races would turn out to be those that were obvious and undeniable.  Not that all unknown but discoverable differences would turn out to align with existing prejudices--but some probably would.  And therein lies the fragility of the dogmatic insistence on the absolute equality of groups.  As soon as research demonstrates a difference between groups that puts a bad light on one relative to the other, racists will seize upon it.  Those of good will can find in respect for individuals as thinking and feeling beings more defensible ground than in clinging to the faith that any group of humans is in all ways that matter just like any other.https://www.nytimes.com/2018/03/23/opinion/sunday/genetics-race.html?smid=fb-share
