Friction as Training
The thesis that lower-order cognitive friction was not only a metabolic cost — it was simultaneously a daily exercise regimen for the prefrontal circuits that support general-purpose executive function across every domain.
Friction as training is the proposition that the metabolic cost of traditional cognitive friction — debugging, hypothesis generation, systematic problem-solving — was simultaneously performing a training function: daily exercise of the prefrontal circuits those operations engaged. The neuroscience of experience-dependent plasticity establishes that neural circuits are strengthened by use. Repeated engagement produces dendritic branching, increased synaptic density, more efficient neurotransmitter cycling. The strengthening is specific — the exercised circuits are strengthened — and cumulative. An engineer who spent ten years debugging has a prefrontal cortex whose error-detection, hypothesis-generation, and logical-analysis circuits have been shaped by ten years of daily exercise. These circuits are not debugging-specific; they are general-purpose executive functions deployed across every domain requiring structured thinking.

The circuits exercised by debugging support capacities that extend far beyond code. Error detection underwrites the capacity to notice flaws in arguments. Hypothesis generation underwrites the capacity to produce alternative explanations for unexpected outcomes. Logical analysis underwrites
