The author is far too "intellectually?" rigid and judgemental. A properly trained psychologist never would make the broad brush sweeping statements that this author dares to spout. It's just stereotypical psychobabble meant to be a "rattling good and simplistic yarn" that sells a lot of books, and this DID sell a LOT of books, to readers whom I would not deign to categorize. If you want a really helpful book on interpersonal relationships written by a highly respected psychiatrist, researcher, and clinician who practices "cognitive therapy", then I would suggest you consider reading "Feeling Good" and "Intimate Connections" by Dr. David D. Burns. Rather than concentrating on peoples' external behavioral characteristics, Burns concentrates on the "internal dialog" of the person reading the book, and how they can recognize and change how they think internally so they can better cope with themselves, their partners, and the people around them. "It all begins at home", and "home" is internal as well as external.
