INTRODUCTION

English translation pending.

CORE DEFINITION

The idea comes from Archimedes' claim that given a place to stand he could move the earth, applied to systems: not all interventions have equal leverage, and a few nodes such as feedback loops, rules, and mental models can restructure a whole. The core claim is that in complex systems the relationship between input and effect is nonlinear, so scarce resources should be aimed at high-leverage points rather than spread evenly. The qualification is that leverage points are often delayed and invisible, which means early results are absent exactly when the temptation to abandon the intervention is greatest.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Map the structure: draw the system and list the variables open to intervention. - Rate the leverage: estimate how much system change each unit of input would produce. - Concentrate and wait: aim resources at the fulcrum and hold through the delay.

Anchor fast decisions

In a system where variables influence one another through feedback, a change at a node with many dependencies propagates through the network and can shift the whole pattern, while the same effort on a peripheral node changes only that node. This is why outcomes are nonlinear in effort. High-leverage points are frequently invisible because they sit in rules and assumptions rather than in visible activity, and their effects arrive after a delay. The delay is the main hazard, since the absence of early feedback invites abandoning the intervention too soon.

Second Law of Thermodynamics

The second law of thermodynamics is one of the four fundamental laws of thermodynamics, stating the irreversibility of thermodynamic processes—isolated systems spontaneously evolve toward thermodynamic equilibrium, the state of maximum entropy. Similarly, a perpetual motion machine of the second kind is impossible. The history of this law can be traced back to Nicolas Carnot's research on the efficiency of heat engines and his Carnot theorem proposed in 1824.
