But that's not where this article is going. There are statistical differences between groups, even though the groups are not well defined at the boundaries, and though there is no single clear way to distinguish them.
Indeed, the groups almost totally overlap. Almost any white man can find some black man he can out jump, and almost any black man can find a white man who can outjump him. The biggest strongest NBA center is a black man, and since George Mikan usually has been. But there are usually both black and white centers succeeding in the NBA at any given time.
These differences are biological and exist, with 99% overlap and no clear boundary. This article doesn't dispute that, though it does its darndest to cloud that fact. Why? What agenda is it persuing? Not one I subscribe to, of that I'm confident.
No one ever argued that the Soviet domination of Chess from 1950 - 90, was evidence of their genetically superior intellectual capacity. Soviet grandmasters agreed that it was their state funded training program that produced their success. link
Whether you call the different subsets of man "races," "classes," "genomes" or anything you like, each recognizable type' of Mankind has a complex of traits--and admittedly the incidence of those traits within any group varies, and overlaps the incidence of those same traits in other groups.
Nothing in that statement means that we can not clearly distinguish between the Bushman of the Kalahari & anyone of another race. (And if lost in a desert, you would be well to hope that the Bushman comes along to help you. That is not intended as an insult to any other group; just an acknowledgement that the Bushman has developed exceptional survival skills in that environment.)
It is no compliment to mankind, that people keep arguing against efforts to classify the variations. With every other variable subject of human interest, we seek to achieve ever more refined classifications; that the opposite has become true as to Mankind is not evidence that we do not have variations, rather of the mischief done by compulsion driven egalitarians. (See Footnote On Egalitarian Compulsion.)
Why does this matter? For just about any concern any society has!
Pretending that people are interchangeable enables demagogues to turn one group against another, over issues of faux grievances. It distracts individuals from actually developing the talents they have, to jealously embracing the politics of envy & resentment. In others, it enables the demagogues to inculcate a sense of guilt.
Of course, it also is grist for the mill of those who would impose a World Order (an internationalist tyranny) over all Mankind, denying the nations of the earth the cultural heritages that have reflected the best of each people's centuries of struggle & social development.
