INTRODUCTION

English translation pending.

CORE DEFINITION

A reasoning method that draws conclusions about an unfamiliar situation by mapping the relational structure of a better-understood source domain onto it. The core proposition is that the mapping must be structural rather than superficial: what transfers is the pattern of relations, such as the way the parts interact, not the appearance or vocabulary of the source. The key qualification is that every analogy has a boundary, so the reasoning must include an explicit test of where the mapping breaks down, since an analogy applied past its limits produces confident conclusions with no support.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Source selection: choose a familiar domain whose internal structure resembles the problem. - Structure mapping: transfer the relations between the parts, not the surface features. - Boundary test: identify exactly where the analogy stops predicting and treat that as its limit.

Anchor fast decisions

A structure with the same pattern of relations behaves the same way under the same operations, so conclusions derived in the source domain hold in the target as long as the structure is preserved. Mapping relations rather than features is what makes the inference valid, because surface similarity carries no guarantee about behavior. The mechanism also explains the failure: when the mapping silently drops a relation that mattered in the source, the conclusion transfers but the conditions that supported it do not.
