Freakonomics 2.0

Just arrived in the mail is a handsome new book called Freakonomics: Revised and Expanded Edition, which should be in stores in a week or two. (Here is the Amazon link.) As the name implies, it is a little bit revised (mostly correcting errors or things that have changed in the world since the book was originally published, in April 2005) and quite a bit expanded (with about 90 new pages including a sampling of our N.Y. Times columns as well as excerpts from this very blog.) For anyone who has already read the book, there’s no likely reason to buy the expanded edition, especially since all the additional material is available online here, for free. But for new readers, the expanded edition would seem to be the better one. FWIW, here’s our preface to the new edition:

As we were writing Freakonomics, we had grave doubts that anyone would actually read it – and we certainly never envisioned the need for this revised and expanded edition. But we are very happy, and grateful, to have been wrong.

So why bother with a revised edition?

There are a few reasons. The first is that the world is a living, breathing, changing thing, whereas a book is not. Once an author finishes a manuscript, it is forced to sit, dead in the water, for nearly a year until it is made ready by the publisher for its debut. This doesn’t pose much of a problem if you have written, say, a history of the Third Punic War. But because Freakonomics explores all sorts of modern real-world issues, and because the modern world tends to change quite fast, we have gone through the book and made a number of minor updates.

Also, we made some mistakes. It was usually a reader who would bring a mistake to our attention, and we very much appreciate this input. Again, most of these changes are quite minor.

The most aggressively revised section of the book is the beginning of Chapter 2, which tells the story of one man’s crusade against the Ku Klux Klan. Several months after Freakonomics was first published, it was brought to our attention that this man’s portrayal of his crusade, and of various other Klan matters, was considerably overstated. For a fuller explanation, see an essay called “Hoodwinked,” on page 231. As unpleasant as it was to acknowledge this error, and to diminish the reputation of a man beloved in many quarters, we felt it was important to set straight the historical record.

We have also futzed a bit with the architecture of the book. In the original version, each chapter was preceded by an excerpt of The New York Times Magazine profile that one of us (Dubner) wrote about the other (Levitt), and which led to this book being written in the first place. Because some readers found these excerpts intrusive (and/or egomaniacal, and/or sycophantic), we have removed them, instead reprinting the complete Times article in the back of this edition on p. 193, in a section labeled “Bonus Material.” There, it can be easily skipped over if one so chooses, or read in isolation.

The further bonus material is what accounts for our having called this edition “expanded” in addition to “revised.” Soon after the original publication of Freakonomics, in April 2005, we began writing a monthly column for The New York Times Magazine. We have included in this edition several of these columns, on subjects ranging from voting behavior to dog poop to the economics of sexual preference.

We have also included here a variety of writings from our blog — which, like this revised edition, was not planned. In the beginning, we built a website merely to perform archival and trafficking functions. We blogged reluctantly, tentatively, infrequently. But as the months went on, and as we discovered an audience of people who had read Freakonomics and were eager to bat its ideas back and forth, we took to it more enthusiastically. A blog, as it turns out, is an author’s perfect antidote for that sickening feeling of being dead in the water once a manuscript has been completed. Particularly for a book like this one, a book of ideas, there is nothing more intoxicating than to be able to extend those ideas, to continue to refine and challenge and wrestle with them, even as the world marches on.

    I just pre-ordered the new version (I lent the original one to someone I don’t want to see again enough that I would rather just buy a new copy!)

    For some reason, I saw the revised & expanded parts. My first reaction: hey, you forget to include my favorite one from NYTM monthly column!!!
    Other than that, I believe ver. 2.0 is well worth spending another $20-30.

    How did you deal with John Lott’s work on guns and crime in the second edition?

    Science is, in the long run, self-correcting. But this process is speeded along by those who take the trouble to improve their own work.
