Cass Sunstein Wants to Nudge Us

In “Nudge,” a popular book that he wrote with the influential behavioral economist Richard Thaler, Sunstein elaborated a philosophy called “libertarian paternalism.” Conservative economists have long stressed that because people are rational, the best way for government to serve the public is to guarantee a fair market and to otherwise get out of the way. But in the real world, Sunstein and Thaler argue, people are subject to all sorts of biases and quirks.
