The SuperFreakonomics chapter on global cooling is still being kicked from one end of the blogosphere to another, with error after tired delusionist error being pointed out. Most of the time, it’s just sloppy contrarianism of the type you might expect from people who hang around with rightwingers a lot and are in a rush to produce a controversial book. But there is one point that, coming from Steve Levitt, I find unforgivable. Before pointing it out, I’ll quote what I said about Freakonomics when it came out, in a post entitled “Getting the data to talk”
what Levitt has taken from the economics profession is not so much a body of theory to be applied, as a set of tools for empirical analysis and an unflinching willingness to look at social and policy issues without regard to social norms or received wisdom. More importantly, he’s combined all this with creative flair and an impressive capacity to see the right way of teasing compelling conclusions out of refractory data.
Looking back, I still think this judgement stands up as regards Freakonomics, which makes the tragedy of Superfreakonomics all the greater.
