INTRODUCTION

English translation pending.

CORE DEFINITION

The parable appears in Su Shi's Essay on the Sun. A blind man asks what the sun is like; someone says it resembles a copper plate, and when he later hears a bell he thinks it is the sun; someone else says it resembles a candle, and after feeling a flute he mistakes that for the sun. The core proposition is that analogy is the fastest tool for learning something new and also the most dangerous one, because a match on a surface property such as shape or sound can be mistaken for a match on essence. The key qualification is that the failure lies not in using analogy but in failing to test which level the analogy holds at.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Name The Layer: state whether your analogy matches structure or only surface appearance. - List The Mismatches: write what the analogy does not transfer before relying on it. - Return To Essence: the moment a comparison misfires, restate the thing in its own terms.

Anchor fast decisions

Analogical transfer works by copying a structure from a known domain into an unfamiliar one, which is enormously efficient. It fails when the features that matched are superficial, because the mind cannot tell a structural match from a perceptual one until the prediction is tested. The blind man transfers the wrong property twice, sound and then touch, because each analogy carried only a single surface feature of the sun. Testing the analogy against the thing itself, rather than against other analogies, is what distinguishes a heuristic from a delusion.

MINIMUM ACTION

In progress 0/1

Practice this model in one real situation:

State the analogy you are using and what exactly it is meant to explain. 2. Mark whether the match is structural or merely on some surface property. 3. List at least two ways the analogy does not carry across. 4. When a prediction fails, drop the analogy and restate the thing directly. 5. Cross-check with a second analogy from a different angle rather than trusting a single one.
