Controlling Complexity with Simplicity
Updated 2026-08-10
INTRODUCTION
English translation pending.
CORE DEFINITION
Controlling Complexity with Simplicity holds that complex systems are often generated by a small number of dominant rules, so understanding and managing them requires identifying those rules rather than modeling every detail. Its core proposition is that simplicity is a form of leverage: one correct high-level variable governs more than many low-level interventions. The key qualifier is that the dominant rule must actually be found, since simplifying before locating it produces a model that is merely thin.
SCAFFOLDING EFFECT
Reduce cognitive load
- Rule search: look for the few dominant rules that together generate all the observed complexity. - Variable separation: distinguish the actual driving variable from all the noise around it. - Leverage check: test whether one change at that level actually moves the whole system.
Anchor fast decisions
Attention and intervention capacity are limited, so addressing detail individually exhausts both. Dominant rules compress the system into a few controllable variables, and changing one of those propagates through everything the rule generates. Leverage therefore comes from locating the generator rather than from working harder on the surface.
