As a comment at RealClimate says with regard to Dubner and Levitt:
So, do Levitt and Dubner list Dunning and Kruger as co-authors on this chapter?I think you'll agree this comment wins the Internet. Meriwether seems to be the ideal type of a certain kind of intellectual failure mode, almost an American original - the man obsessed by the notion that his (almost always) numerical expertise makes him an all-round expert.
Nathan Myrhold is another - he even called his post-Microsoft hobby company "Intellectual Ventures", which ought to put a rough value on the degree of wankishness we're dealing with here. But, of course, they aren't intellectuals or even technocrats; they specialise in hyper-specialisation, rather than any broader culture, and by the time they reach this point they are usually many years from dealing with anything practical.
In fact, as a cultural type, they're almost Soviet figures; believers that if you can get that input-output table\Gaussian copula just right, we'll be able to achieve the new man and true communism\hedge the entire economy perfectly.
