Physicist : Climate Change :: Economist : Effect of Poverty on Schools

Krugman:

Richard Muller, the skeptic we’re talking about, seems to have had different motivations from many of the professional climate skeptics. He basically appears to have suffered from nothing more than characteristic physicist arrogance, the belief that people in lesser sciences just don’t know what they’re doing. (Economists experience this all the time, but we make up for it by being equally condescending to sociologists.) To his credit, he went and tried to do better — and is now being honest in revealing that what he got was pretty much the same as the results of previous research.
