US journalist John Derbyshire has published a screed comprising racist advice to his son. Among the tendentious statements contained in it is this one:
(5) As with any population of such a size, there is great variation among blacks in every human trait (except, obviously, the trait of identifying oneself as black). They come fat, thin, tall, short, dumb, smart, introverted, extroverted, honest, crooked, athletic, sedentary, fastidious, sloppy, amiable, and obnoxious. There are black geniuses and black morons. There are black saints and black psychopaths. In a population of forty million, you will find almost any human type. Only at the far, far extremes of certain traits are there absences. There are, for example, no black Fields Medal winners. While this is civilizationally consequential, it will not likely ever be important to you personally. Most people live and die without ever meeting (or wishing to meet) a Fields Medal winner.
