INTRODUCTION

English translation pending.

CORE DEFINITION

A category mistake assigns a property or object to a logical type it does not belong to, as when the mind is treated as an object of the same type as the brain. The result is a statement that is not merely false but fails to make sense, because the predicate does not apply to that type. The remedy is to restate the claim with its objects in the right category.

SCAFFOLDING EFFECT

Reduce cognitive load

- Type tagging: mark each object in the claim with its logical type. - Predicate check: ask whether the predicate actually applies to that type. - Reassign: restate the claim so its objects sit in the right category.

Anchor fast decisions

Comparing or predicating across types produces nonsense rather than falsehood, because the framework of comparison has no place for the object. Locating the mismatch shows that the appearance of a deep puzzle comes from putting things at the wrong level.

MINIMUM ACTION

In progress 0/1

Practice this model in one real situation:

Mark the objects in the proposition and their logical types. 2. Check whether the predicate applies to that type. 3. Point out the mistake when a term is used across levels or classes. 4. Restate the claim in the correct category. 5. Check whether the whole argument rests on this mismatch.
