INTRODUCTION

English translation pending.

CORE DEFINITION

However wise, a person deliberating a thousand times will err once; however foolish, will be right once. The model attacks both the worship of experts and the contempt for novices: since even the finest judgment carries a necessary failure rate, any critical system must build in redundancy and fault tolerance rather than relying on the infallibility of its single best mind.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Breaks expert worship: even the finest mind carries a genuinely nonzero error rate - Requires redundancy: systems are designed around the expert's certain future mistake - Welcomes the outsider: the novice's one right answer is also structurally expected

anchor

Anchor fast decisions

Bias and incomplete information are irreducible within any single reasoner, so a deterministic failure rate survives every increase in diligence. Only external redundancy changes the odds: an independent second opinion catches errors that additional thought by the same mind cannot, which is exactly why engineering and medicine institutionalize the practice.
