I am disappointed in you, John Gottman. If I didn't know better, I would think this book was published just for the sake of having another book under your belt, sir. Was all of that stuff at the beginning really necessary? Are you really a "closet mathematician?" A lot of that math and statistics seemed a little sketchy to me, especially your interpretations of the various prisoners' dilemma solutions. Also, maybe next time you should have your notes looked through, just for grammatical correctness, by one of your grad students before you sweep them up off your desk and send them off to be bound and published.
