In When to Rob a Bank, they ask a host of typically off-center questions: Why dont flight attendants get tipped? If you were a terrorist, how would you attack? And why does KFC always run out of fried chicken? Over the past decade, Steven D. Levitt and Stephen J. Dubner have published more than 8,000 blog posts on Freakonomics.com. Many of them, they freely admit, were rubbish. But now theyve gone through and picked the best of the best. Youll discover what people lie about, and why; the best way to cut gun deaths; why it might be time for a sex tax; and, yes, when to rob a bank. (Short answer: never; the ROI is terrible.) Youll also learn a great deal about Levitt and Dubners own quirks and passions, from gambling and golf to backgammon and the abolition of the penny.
