Steven D. Levitt is an economist. Stephen J. Dubner is a writer. In 2005, they co-authored Freakonomics, a book about cheating teachers, bizarre baby names, and crack-selling mama’s boys. They figured it would sell about 80 copies. Instead, it has sold 5.5 million, in roughly 40 languages. In 2009, they followed up with SuperFreakonomics, with stories about drunk walking, the economics of prostitution, and how to stop global warming. (To date, SuperFreakonomics has sold 1.5 million copies.) In 2014, Dubner and Levitt published Think Like a Freak: The Authors of Freakonomics Offer to Retrain Your Brain, which made its debut at No. 2 on the New York Times best-seller list. Their latest book, to be published in May 2015, is When to Rob a Bank: …And 131 More Warped Suggestions and Well-Intended Rants. It is a compilation of “greatest hits” from 10 years of blogging at Freakonomics.com. Along the way, a lot of other stuff has happened too. An award-winning blog. A movie. Lectures. And a No. 1-ranked podcast, with more than 5 million monthly downloads. This is the place where all that stuff continues to happen. Welcome to Freakonomics.com.
