Chapter 9 | Where Models, Methods, and Tools Are Most Easily Confused
Many failures come from using a tool as a method, a slogan as a model, or a method where a deeper judgment is needed.
Core idea: Clear boundaries prevent category mistakes in thinking and action.
How to read it: treat the chapter as a working frame. Identify the situation it describes, the mistake it warns against, and the standard it asks you to build into your own system.
Static practice: Review one recent failure and identify whether the real mistake was at the model, method, or tool layer.
