Clever. I think Levitt and Dubner have a hidden agenda with this book, which really should've just been title How To Be a Better Person. It's got a lot on those lines: learn to say I Don't Know, learn to question yourself, learn to think beyond just superficially, learn to actually see other people. Learn to let some things go. Basically, a mix of Science and Compassion For Beginners. Freaking brilliant, really—if only it could make it to the right audience. (That's the snag.)

Engaging, fun, even charming. Definitely a book to pass along to those in need.
