Cass Sunstein has been whetting appetites for his new book, Simpler: the Future of Government (out April 9) by doling out tasty samples of its content (see e.g. here and here). One of these is an essay for Foreign Affairs, "Regulatory Moneyball". The title is borrowed from Michael Lewis' superb Moneyball: the Art of Winning in an Unfair Game, about Billy Beane's use of statistics to get the jump on baseball clubs who relied on hunches and instinct.
