Last weekend I finally read Freakonomics. If you haven't read it yet, it really is just as good as it has been made out to be. And it can be read in a weekend.
There is also a lot of great stuff recently on the Freakonomics blog. Just in time for Election Day tomorrow (check your local stations) they have a post on why people vote and in a similar electoral vein, Levitt concludes that according to his research, Richard Daley actually did not steal the 1960 Presidential election for JFK.
