I guess in the context for which it’s intended, it works OK. It’s a book introduction, after all. Most irrational people don’t really have much of a map of where and how they are being irrational—and in fact commonly consider themselves to be very rational persons, when it comes to it. (I strongly suspect this is like driving—most people considering themselves to be above average—where being incompetent also robs you of awareness of your lack of performance...) The common reaction would probably be to nod along, thinking how terrible it is that all these people are so irrational, and enjoy the read. For an introduction, that’s good enough.
