The Man from Zheng Buying Shoes
Updated 2026-08-09
INTRODUCTION
English translation pending.
CORE DEFINITION
From the Han Feizi, the story describes a man from Zheng who measures his foot, leaves the measure at home, and when it is missing refuses to try the shoe on, saying he would rather trust the measurement than his own foot. The tale targets rigid adherence to doctrine over direct evidence. Its proposition is that rules and metrics are instruments for testing reality, and when instrument and reality disagree it is the instrument that must yield.
SCAFFOLDING EFFECT
Reduce cognitive load
- Test against reality: when a metric conflicts with direct observation, go back and look at the object itself. - Question inherited rules: ask whether a standing procedure still fits the case in front of you. - Prefer the ground truth: treat first-hand evidence as the final arbiter rather than the report.
Anchor fast decisions
A proxy measure is created to represent a real object, then gradually acquires authority over it. Once the proxy is treated as the thing itself, evidence from the object can be rejected as noise, and decisions drift away from the conditions they were meant to track. Restoring the object as the final test breaks that inversion.
