Three Cobblers Outshine Zhuge Liang
Updated 2026-08-10
INTRODUCTION
English translation pending.
CORE DEFINITION
A Chinese proverb stating that three cobblers together match the strategist Zhuge Liang. Its core proposition, aligned with the wisdom-of-crowds literature, is that aggregating independent and diverse judgments cancels individual errors and outperforms even a strong single expert. The qualifier is strict: aggregation works only when judgments are formed independently and participants bring different information, so conformity or shared background destroys the advantage.
SCAFFOLDING EFFECT
Reduce cognitive load
- Diversity first: recruit people whose backgrounds and information sources actually differ from yours. - Independent round: collect each person's estimate before any group discussion begins. - Aggregation rule: combine the independent estimates by averaging or structured debate rather than consensus talk.
Anchor fast decisions
Individual judgments each carry idiosyncratic error, and when those errors are uncorrelated they cancel as estimates are pooled, leaving the shared signal. This requires independence at the moment of judgment, because discussion transmits the same bias through every participant, so the errors become correlated and no longer cancel.
