Long story short, it's like the kerfuffle a while back between me and Bob Murphy about his own, um, imprecise commentary on global warming, except that the mistakes by Levitt and Dubner were much bigger, they got called on their shoddiness by a lot more people, and they continued to dig themselves much deeper that Bob ever tried to. To top it off, they deliberately misrepresented one of their experts (Ken Caldeira added the quote you see to his web page in contradiction of a position attributed to him in the book after he found out what was in it.)
(Note: this isn't about "rah rah let's cut carbon emissions" vs. "those durn whiny hippies". Regardless of your opinion on the issue, Levitt and Dubner's handling was extremely shoddy, and exactly the kind of thing that neither side should want, even and especially if you agree with their policy positions.)
With that in mind, take a look at this post on the Freakonomics blog, where Levitt complains that he's unfairly portrayed, in his university's alumni magazine, as someone not tackling the "big questions" and who's ruining economics.
Yep, this is one of those times when only Silas-grade sarcasm will do. Here's what I posted:
Well, it's a good thing you've moved on from sumo-wrestling into important issues like global warming, where you've carefully researched the issue, accurately represented expert opinion, and presented an even-handed, informative discussion of the issue that helps sustain the University of Chicago's excellent reputation.
Needless to say, the comment didn't make it through moderation.
By the way, it's my birthday today! Wish me a happy 28th if you haven't already!
