Yeah, part of me really admires the hell out of his creativity and approach but another part of me thinks his work can be amateurish.
I saw critique that said the second book was weaker because he was relying on research he himself did not conduct and he wasn't as skeptical of it as he should be, but he and Dubner both seem to really enjoy being contrarian for its own sake.
So I just browsed through Amazon's best books of 2012 list and got the following:
The Fault in Our Stars by John Green (thanks to irondarts)
The Thief by Fuminori Nakamura
Fooling Houdini by Alex Stone
Days of Destruction, Days of Revolt by Chris Hedges
How to be a Person: The Strangers Guide to College, Sex, Intoxicants, Tacos, and Life Itself
