INTRODUCTION

English translation pending.

CORE DEFINITION

A logical fallacy, also called the argument to moderation, in which the midpoint between two opposing positions is assumed to be true simply because it sits between them. Its core proposition is that truth does not shift with the distribution of opinions, so if one side is clearly right or both sides are wrong, the compromise remains wrong, and on questions of fact the conclusion must follow the evidence rather than symmetry. The qualifier is that the fallacy applies to factual claims, since value trade-offs may legitimately be split.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Evidence test: examine the evidence that stands behind each of the two opposing claims. - Midpoint check: ask whether the middle position has independent support of its own. - Type sorting: separate factual questions, which cannot be split, from value trade-offs about preferences.

The fallacy treats the position of a claim as if it carried information about its truth, so symmetry between two speakers substitutes for evidence about the world. Since the strength of a claim depends on what supports it and not on where it sits on a spectrum, a compromise between a well-supported claim and an unsupported one inherits the weakness of the weaker side.
