Race and IQ

A useful nuance in the debate:

Geneticists have come up with the concept of a reaction norm to describe the range of environments in which a genetic trait might develop. Under this view, characteristics of organisms are not either innate or learned: they vary in the width of the reaction norm describing the kind of environmental inputs they require. Under this view, the race and IQ question comes down to the question of whether African IQ deficits are like dark African skin, so pervasive across all imaginable environments that calling them innate is perfectly reasonable as a first approximation, or more like African-American success in popular music, for which we require no scientific evidence to attribute to the particular combination of history, culture and sociology of the present time. We are justifiably offended by a hypotheses involving, say, an innate gift of rhythm.

What we’re discussing is a function of both genetics and environment and their interaction. I don’t think those pointing out resilient racial differences in IQ are positing anything as crude as "innate."

The Stem-Cell Debate

A Christianist predicts:

Narratives about positions on public policy are like enormous steamships: It takes a long time to turn them around. But if the news of stem-cell breakthroughs prove accurate, we may well see over the next few years a gradual reversal in news stories and editorials. Watch for it, now that abortion is out of the equation: Much less hype about all the miracle cures that stem cells will bring us, more suspicion about the cancers and genetic pollution that may result, and just about the same amount of bashing of religious believers—this time for their ignorant support of science.

Face Of The Day

Bangladeshi cyclone-affected man Khalilur Rahman, who lost 11 members of his family including his wife and his other children, cries holding his only survived daughter while waiting to get relief goods in Fokirghat, on the southern coastal area of Bangladesh, 20 November 2007. Urgently-needed supplies of food, water and medicine were nearing people in remote areas of Bangladesh where a devastating cyclone has left millions homeless and thousands dead. With roads now cleared of hundreds of trees that had blocked aid convoys, officials said relief was finally starting to get through to the most inaccessible areas four days after the colossal storm hit.

Cook on Krugman

Right, but wrong:

I think Paul’s rebuttal [to Ruth Marcus] is correct, so far as the "circumstances" are concerned. But the circumstances are of course not the only thing to have changed since he opined on this topic in the past. His modes of analysis and expression have changed too, and radically, in ways that often seem calculated to obscure the fact that he is one of the four or five most brilliant economists of his generation. This is not incompetence or inadvertence on his part; it appears to be a conscientious choice. He wants to fuel the rage of the administration’s opponents more than he wants to help people think through the arguments. He feels that this now serves the greater good. Bush and his people are too wicked for dispassionate analysis, he believes; there will be time for Seriousness later.
