To some extent, I could agree with that idea. One purpose of that process is to match the impedance between the problem, and human cognition. But that presumes problem solving inherently requires human cognition, which is false; that's just the tool that we have for problem solving. When the problem-solving method matches the cognitive strengths and weaknesses of the problem solvers, they do have a certain sensation of having an upper hand over the problem. Part of that comes from the chunking/division allowing the problem solvers to more easily talk about the problem; have conversations and narratives around it. The ability to spin coherent narratives feels like rigor.
