I see a lot of so-called software experts fall into the exact same category as the author of that book... believing themselves to be experts just because they worked in the field for a while, despite having no scientific training, or any relevant training for that matter, no serious studies backing up whatever they promote, nothing except for a lot of gut feeling and on-the-job "hands-on knowledge", exactly as the author of this book who believed himself to be an expert in communication and psychology despite lacking even a basic understanding of that. We should apply the same kind of scrutinization when it comes to the software industry IMO. Just because you wrote code for a few years and managed a team later, doesn't mean anything you learned is applicable to anyone else. Imagine doctors going around experimenting on people and "learning hands-on" what works and what doesn't. Or even electricians or plumbers... yet, here we are, and I feel like it's exactly what we're doing with software development.
