The New York Times bestselling Freakonomics was a worldwide sensation, selling more than 4 million copies in 35 languages, and changing the way we look at the world. Authors Steven D. Levitt and Stephen J. Dubner followed it up with SuperFreakonomics, a Freakquel that hardcore fans and newcomers alike have found to be even bolder, funnier, and more surprising than the first.

Four years in the making, SuperFreakonomics asks not only the tough questions, but the unexpected ones: What’s more dangerous, driving drunk or walking drunk? Why is chemotherapy prescribed so often if it’s so ineffective? Can a sex change boost your salary?

SuperFreakonomics challenges the way we think all over again, exploring the hidden side of everything with such questions as:

•How is a street prostitute like a department-store Santa?
•Why are doctors so bad at washing their hands?
•How much good do car seats do?
•What’s the best way to catch a terrorist?
•Did TV cause a rise in crime?
•What do hurricanes, heart attacks, and highway deaths have in common?
•Are people hardwired for altruism or selfishness?
•Can eating kangaroo save the planet?
•Who adds more value: a pimp or a realtor?
