Glenn, John, and Philip K. DickPhilosopherMichael Levin has the answer to this, in his 1997 book Why Race Matters,
In the last segment of their recent bloggingheads discussion, John McWhorter told Glenn Loury he was writing a piece suggesting that discussions of an IQ gap be deemed unacceptable for public discourse1:
I don’t understand what possible benefit there could be. I think it should stay in the journals.Glenn agreed, and mentioned his famous response to the conservative welcome of The Bell Curve, in which he angrily rejected Murray’s assertions.
My first, instantaneous reaction was hey, great idea. In fact, it will save us billions. Too bad no one proposed it twenty years ago, before we wasted so much time and energy on No Child Left Behind, forcing states to report by racial demographics. Think of all the schools struggling to meet adequate yearly progress and failing because they couldn’t teach students to perform in perfectly average racial unity. Let’s be sure to tell the College Board; they’ll be happy to stop breaking out test results by race; it’ll save them so much criticism. This will put NAEP out of business of course, so….
What’s that? You don’t think McWhorter would link banning discourse on race and IQ to ending all scrutiny of race-based academic achievement?
Ya think? [More]
“The topic of racial variation is admittedly disturbing, and in an ideal world might be passed over in silence, but accusations against whites have made such discretion impossible. The right of the accused to present his case includes the right to raise issues that distress his accuser. A plaintiff demanding damages for a broken leg cannot ask at the same time that his leg not be talked about, nor take offense when the defendant presents evidence that the injury was congenital. By claiming harm he opens the question of why his leg is game. Claiming racial harm has opened the topic of race differences. “Of course, opening the topic of race differences (in response to claims of white racism) is sort of what got John Derbyshire fired from National Review, and now John McWhorter (who, I remind you, is a somewhat conservative black) has published an article saying

There isn't actually a discussion on race and IQ. In the public sphere, there's no discussion because it's banned, enforced by firings, or when the discusser has tenure, by mob violence. In scientific sphere, there's no discussion because the science is settled. [Thirty Years of Research on Black-White Differences in Cognitive Ability, by J. Philippe Rushton and Arthur R. Jensen,· June 2005 PDF]
But I reiterate, the unscientific belief that, but for racism, blacks and whites would score equally on tests is the source of a lot of grief. Oh, and the reason Education Realist's post was titled Glenn, John, and Philip K. Dick is because science fiction author (and psychedelic drug user) Dick was the author of the maxim “Reality is that which, when you stop believing in it, doesn’t go away.”
