INTRODUCTION

English translation pending.

CORE DEFINITION

The inductive turkey is a parable used to illustrate the problem of induction. A turkey observes that it is fed every morning at nine o'clock, treats the regularity as a law, and is proved wrong on the morning of Thanksgiving, when the same regularity delivers it to slaughter. The core proposition is that accumulating confirming instances raises confidence without bounding the risk of a structural break, so a long unbroken record can be least informative just before it ends. The key qualification is that induction remains indispensable in stable domains, so the parable warns against treating regularity as certainty rather than against generalizing at all.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Count The Breaks: ask what structural change could end the pattern you are relying on. - Monitor The Assumption: track the conditions the pattern depends on, not only its past record. - Weight The Tail: treat rare catastrophic outcomes as material even when they have never occurred.

Anchor fast decisions

Each confirming observation raises the apparent reliability of a regularity, and the confidence curve flattens as the record lengthens, so the model feels safest immediately before a break. Nothing in the observations reveals the conditions that sustain the pattern, so a change in those conditions arrives with no warning in the data. Because the worst outcome is unobserved by construction, its probability cannot be estimated from the record itself.

MINIMUM ACTION

In progress 0/1

Practice this model in one real situation:

State the regularity you are relying on and the decisions that depend on it. 2. Ask which structural condition keeps that regularity true. 3. Look for evidence about that condition rather than more confirming cases. 4. Identify the worst outcome the pattern permits and its cost. 5. Set a trigger that would tell you the structure has changed.
