Race Difference in Intelligence (RDI) researchers have been trying to prove their case since World War I when psychologists administered intelligence tests to those entering the Army. It won’t surprise you to learn that one outcome of this mass testing was the blustery assurance among psychologists that at last we had definitive proof of differences in intelligence between the races. However, the case soon fell apart and RDI researchers, the honest ones at least, issued embarrassed recantations. Most famous of these was Carl Brigham who wrote in 1930:
This review has summarized some of the more recent test findings which show that comparative studies of various national and racial groups may not be made with existing tests, and which show, in particular, that one of the most pretentious of these comparative racial studies-the writer’s own-was without foundation.
Brigham was merely echoing many other researchers who realized that intelligence tests could never really prove that white people are smarter than black people and not much could be done about it. For the past century, however, a few RDI researchers always lumbered on, promising that, any day now, we are right on the brink, success is just around the corner, just fifteen more minutes!, and we will have proof that most of the racial gap in IQ owes to genetics.
The latest entry into the jam-tomorrow-never-jam-today of RDI researchers is this piece by philosopher Nathan Cofnas who assures us that “In a very short time” we will know that black people are just generally dumber than white people (I paraphrase here, but that is what he means) . It is never a good sign when an article comes with a warning label as this one did. The editors claimed their decision was “based on criteria of philosophical and scientific merit, rather than ideological conformity.” One wonders what merit the editors found in the article since it has none of these promised virtues.
