Great NYT story on libertarian paternalism and the British "Nudge Unit." In part:
Despite such squabbles, the question in Britain no longer seems to be whether, but how, to nudge. In their book, Professor Thaler and Mr. Sunstein defined their approach as steering people toward decisions deemed superior by the government but leaving them free to choose. “Libertarian paternalism,” they called it, and while that term is not used much in Britain, there is broad agreement on the subject among the left and the right.
