CORE DEFINITION

Alder’s razor, discussed by Mike Alder and also called Newton’s flaming laser sword, requires empirical propositions in a dispute to connect through logic or mathematics to observable consequences. It distinguishes empirically testable issues from merely verbal disputes.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

Examine the empirical parts of philosophical or everyday claims through their observable consequences, while distinguishing value judgments and currently untestable aspects. Lack of an immediate experiment does not justify dismissing all philosophy.

anchor

Anchor fast decisions

Demanding a derivational link between propositions and observations makes parties specify what evidence would change their judgments. It clarifies empirical content rather than automatically deciding every truth or value question.
