Commensurability Method

INTRODUCTION
English translation pending.
CORE DEFINITION
Commensurability concerns whether two frameworks share enough common measure to be compared term by term. Thomas Kuhn used incommensurability to argue that successive scientific paradigms embed different concepts, standards, and problems, so their terms cannot simply be mapped onto one another. The method turns this into a practical check: before comparing options, ask whether a conversion exists between their units of value. The qualification is that incommensurability is a matter of degree, and translation is often possible even when direct conversion is not.
SCAFFOLDING EFFECT
Reduce cognitive load
- Comparability test: ask whether the two options share a unit before you rank them. - Translation step: build an explicit exchange rate when only a partial common measure exists. - Decision guard: refuse a ranking that silently assumes two incommensurable values sit on one scale.
Anchor fast decisions
Comparison requires a common dimension, so two items can be ordered only if each maps onto the same measurable scale. When frameworks differ in their units and standards, any direct ranking smuggles in an exchange rate that was never justified. Making the conversion explicit either produces a defensible scale or exposes that none exists, which is why the check precedes the comparison rather than following it.
