INTRODUCTION

English translation pending.

CORE DEFINITION

A hypothesis in non-equilibrium thermodynamics stating that an open system held away from equilibrium tends toward the steady state that maximizes its rate of entropy production, meaning the fastest dissipation of available gradients. The Earth's climate is sometimes cited, since atmospheric and oceanic circulation transports heat from the equator toward the poles at a rate consistent with the principle. It remains a hypothesis rather than a universal law, and its status and scope are actively debated. It should not be confused with the maximum entropy principle used in statistical inference.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Dissipation lens: ask which configuration of a system burns through its gradients fastest when predicting its direction. - Efficiency driver: expect patterns that process information or capital faster to displace slower ones. - Claim discipline: label it a hypothesis when using it, since it is not a universal law.

Anchor fast decisions

A gradient represents stored free energy, and a system far from equilibrium has many possible paths for releasing it. The principle asserts that the realized path is the one that discharges the gradient most rapidly, which selects for configurations with high throughput rather than high efficiency in the ordinary sense. The selection is not deliberate; it emerges from the stability properties of the steady states available to the system, which is why the claim is stated as a tendency rather than a mechanism with a director.

Fordism

Fordism describes an economic and social system based on industrialized and standardized mass production and mass consumption. This concept, named after Henry Ford, is widely used in sociology, economics, and management studies, particularly concerning production, working conditions, consumption, and other related phenomena in the 20th century.
