The book's introduction should tell you right off the bat that these two authors have strayed away from science and reasoning towards controversial statements meant to generate... well, controversy and revenue. From now on, their books should be in the fiction sections of bookstores and libraries. Advocating drunk driving in any condition borders on the side of evil. Don't tell me that the book suggests that drunk people should call a cab or hitch a ride with a friend. When someone is drunk and they're holding car keys, do you really think they're going to do anything other than drive? Shame on you Steven and Stephen. Shame.
I think that we just need to realize that these are economists writing about atypical topics. They don't consider morals because that's simply not part of thinking like an economist. I think that Levitt and Dubner are brilliant with their ideas. They make you think and question the world. You don't have to believe what they say, but their statistic do back it up. Maybe they make controversial statements, but isn't controversy good? They are writing like people who look at numbers and search for relationships. What they find may be some correlation and causation, but just take their information with that in mind. They are not out to change the world, they're out to change the way we think about the world. You don't have to believe a word they say, but believe they are voicing a side you've never looked at that might be worth looking in to.
