For Thaler, every one of the biases is a reason not to trust people to make their own choices about money. It's an old routine in economics. Since 1848, one expert after another has set up shop finding "imperfections" in the market economy that Smith and Mill and Bastiat had come to understand as a pretty good system for supporting human flourishing. . . .
Like with the psychologist's list of biases, though, nowhere has anyone shown that the imperfections in the market amount to much in damaging the economy overall. People do get across the street. Income per head since 1848 has increased by a factor of 20 or 30. It is a scientifically bizarre oversight, as though a geologist offered an alternative theory of plate tectonics without showing that her ideas do a better job of explaining the shape of mountains or the alignment of the continents.
