It's an incredible book, one of the most astute things I've ever read. And the patterns apply widely. I've found it very useful in diagnosing bad bosses. Once my boss's boss fired my boss and suddenly took over managing me. After my first meeting with him, where a nominal 30-minute chat turned into 90 minutes of berating, I walked out wondering what the hell happened. I grabbed my copy of "Why Does He Do That?" and quickly found him described as abuser subtype "Mr Right". It was a huge relief just to be able to put the head-spinning experience in perspective. And it let me really prepare for the rest of my (short) tenure there.
