In 2005, Freakonomics exploded like a bomb on the culture, forever changing the way we understand the way the world works, how we really make decisions, and... how we name our children. After more than two years on the New York Times bestseller list, three million copies sold, and single-handedly inventing a genre of books, University of Chicago economist Steven Levitt and New York Times writer Stephen Dubner now return with SUPERFREAKONOMICS. Based on entirely new research, it's bigger, more provocative, and ready to challenge the way we think all over again.
