Consider the titles of his chapters:
Don't Accept Free Drinks: Reciprocity
Leave Your Supermodel Friends at Home: Contrast Effect
If You have Nothing to Say, Say Nothing: Twaddle Tendency
Live Each Day as If It Were Your Last--but Only on Sundays: Hyperbolic Discounting
As I read the book, I found that my thinking began to become more muddled. Logic was crowded out by fallacy. I have always prided myself in rational thinking but I can see how emotions can impact decisions. I was getting worried until I read the Epilogue where the author admits that he does not live an error-free life. He sums things up in this manner: "Nature doesn't seem to mind if our decisions are perfect or not, as long as we can maneuver ourselves through life--and as long as we are ready to be rational when it comes to crunch." (p 305)
Well, that sounds good enough for me. Methinks I overthinketh.
