If you're don't read books, I don't think this is a bridge you'll cross. And I'm sorry you find two respected professors, one at NYU and one at Stanford, to be of dubious authenticity. I'm not quite sure where to go from there in the conversation. There are many individuals who find Pfeffer dubious, but de Mesquita is extremely highly regarded.
I'm not going to share my background on the internet, but ex-CEO doesn't make you qualified to talk about much of anything. It depends on the organization. I've virtually never seen these sorts of dynamics at organizations below 100 people, and they don't become universal until around 1000-10,000 people. You need to reach a certain scale of competition before people start acting in ways which are game-theoretically optimal. If you have 10 people, it's easy to keep alignment on mission, vision, community, and business. If you have e.g. 10,000 people, and 1% are gunning for CEO, the only way to get to the top is to out-gun the other 99. That competition is what leads to these dynamics.
