In their books "Freakonomics," "SuperFreakonomics" and "Think Like a Freak", Steven D. Levitt and Stephen J. Dubner explore "the hidden side of everything," telling stories about cheating schoolteachers and eating champions while teaching us all to think a bit more creatively, rationally, and productively. The Freakonomics Radio podcast, hosted by Dubner, carries on that tradition with weekly episodes. Prepare to be enlightened, engaged, perhaps enraged, and definitely surprised.
