INTRODUCTION

English translation pending.

CORE DEFINITION

From Gregory Chaitin's work on algorithmic information theory in the 1960s, building on Kolmogorov complexity. The claim is that for most strings the shortest program producing them is no shorter than the string itself, so they are algorithmically random. The result applies to most objects rather than to all: some facts do compress, and those are the ones that carry explanations.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Randomness acceptance: Stop searching for a cause behind events that carry no compressible pattern. - Overfitting check: Treat a story that fits every data point as a sign of fitting noise. - Narrative discipline: Drop the question of why this happened to me when no mechanism exists.

Anchor fast decisions

Compression works by finding regularities, and regularity is rare among all possible objects. Counting shows that the overwhelming majority of strings cannot be produced by any description shorter than themselves. A search for a simpler theory therefore has no guarantee of success, and inventing one anyway fits the observer's noise rather than the world's structure.
