So this book was pretty good. Maybe without all the hype I would've given it five stars, but a couple things were holding me back. First, I loved the idea of applying economic tools to subjects besides just economics. But the book was kind of short and pithy. I really could've gone for more analysis, or at least seeing more of the data that they tout as all-telling. (I guess that's part of what makes it so readable) They also seemed, to me, to be a little too hung up on how "freaky" they were. Cut it out, dudes--none of that was freaky, just interesting.
