INTRODUCTION

English translation pending.

CORE DEFINITION

Drawn from Jorge Luis Borges's one-paragraph story 'On Exactitude in Science', which describes an empire whose cartographers produce a map the size of the empire itself. The claim is that representation works by subtraction, so a one-to-one copy forfeits the guidance a map provides. The condition is that the map must serve a decision; a model with no purpose has no standard for what to omit.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Lossy by design: Treat deliberate omission of detail as the core design act, not a failure. - Decision anchor: Choose what to keep by asking which decision the model must support. - Coverage release: Drop the guilt about being partial, since full coverage equals no model.

anchor

Anchor fast decisions

A model earns its value by compressing the territory into a structure small enough to hold in mind. Each detail retained adds fidelity but also adds the cost of the territory itself. Past the point where the model is as complex as what it describes, it can no longer guide action, because consulting it is as hard as consulting reality.
