INTRODUCTION

English translation pending.

CORE DEFINITION

The curse of knowledge is a cognitive bias in which better-informed people systematically fail to model the mental state of less-informed people. The term comes from economics research on bargaining and was popularized for teaching and communication by Chip and Dan Heath in Made to Stick. Its core proposition is that knowledge is not additive but restructuring: it changes which steps feel obvious, so experts omit exactly the bridging steps novices lack. The key qualifier is that the bias is a side effect of competence rather than a knowledge deficit, and it cannot be corrected by trying harder to imagine a novice.

SCAFFOLDING EFFECT

Reduce cognitive load

- Teaching reset: Ask what a listener must already believe for your first sentence to make sense. - Test design: Have a real beginner use your material instead of imagining how they would react. - Analogy first: Build the bridge with an everyday comparison before introducing technical vocabulary.

Anchor fast decisions

Once a concept is learned, its representation is activated as a whole, so intermediate inferential steps are no longer re-derived and stop feeling like steps at all. The expert's fluency is then read as evidence that the material is simple, which justifies compressing the explanation further. Because the missing steps are invisible from inside the expert's own model, introspection cannot detect the gap, and only an external novice can surface it.

MINIMUM ACTION

In progress 0/1

Practice this model in one real situation:

Write the explanation, then delete every term a beginner would not know. 2. Replace each removed term with an everyday analogy or a concrete example. 3. Hand the material to a genuine beginner and watch where they stop. 4. Ask them to explain it back and note every gap they fill in wrongly. 5. Rewrite only the steps that the test exposed as missing.
