Ratchet Effect
Updated 2026-08-08
INTRODUCTION
English translation pending.
CORE DEFINITION
The ratchet effect describes the one-way rigidity of a system in which a level, once reached, is difficult to reverse. Wages, entitlements, living standards, headcount and military spending all tend to rise easily and fall only with great difficulty. The mechanism is a combination of path dependence and asymmetric adjustment costs: commitments made at the higher level create expectations and obligations that cannot simply be withdrawn. The image is a ratchet wheel that turns forward freely and locks against reverse motion.
SCAFFOLDING EFFECT
Reduce cognitive load
- Check reversibility: ask whether a level you raise could realistically be lowered again. - Price the commitment: treat any permanent promise as a cost that outlasts the current conditions. - Keep slack: design arrangements that can flex downward instead of locking at the peak.
Anchor fast decisions
Once a level has been raised, the people who benefit treat it as the new baseline and organize around it. Lowering it imposes concentrated, visible losses on them while the gain from lowering is diffuse and delayed, so resistance is intense and support is weak. Commitments made at the higher level, such as contracts and expectations, further raise the cost of reversal. Because the asymmetry repeats at each step, the level drifts upward permanently even when conditions return to where they started.
