The non-fiction publishing phenomenon known as Freakonomics has passed its eighth anniversary. The original book, which used ideas from statistics and economics to explore real-world problems, was an instant best-seller.
By 2013, it had sold more than five million copies worldwide, and it has sprouted a franchise, which includes a best-selling sequel,SuperFreakonomics; an occasional column in the New York Times Magazine; a popular blog; and a documentary film.
The word “freakonomics” has come to stand for a light-hearted and contrarian, yet rigorous and quantitative, way of looking at the world.
The faces of Freakonomics are Steven D. Levitt, an award-winning professor of economics at the University of Chicago, and Stephen J. Dubner, a widely published New York–based journalist. Levitt is celebrated for using data and statistics to solve an array of problems not typically associated with economics.
Dubner has perfected the formula for conveying the excitement of Levitt’s research—and of the growing body of work by his collaborators and followers. On the heels of Freakonomics, the pop-economics or pop-statistics genre has attracted a surge of interest, with more authors adopting an anecdotal, narrative style.
As the authors of statistics-themed books for general audiences, we can attest that Levitt and Dubner’s success is not easily attained. And, we recognize the challenge of creating interest in the subject without resorting to cliché-examples such as baseball averages, movie grosses and political polls.
The other side of this challenge, though, is presenting ideas in interesting ways without oversimplifying them or misleading ideas. Me and others have noted a discouraging tendency in the Freakonomics body of work to present speculative or even erroneous claims with an air of certainty. Considering such problems yields useful lessons for those who wish to popularize statistical ideas.
