Bright-line Rule
Version 1.0.0 · Updated 2026-07-30
CORE DEFINITION
A clear, objective rule that leaves no room for interpretation (e.g., "no alcohol under 18"), as opposed to a vague standard (e.g., "drink in moderation").
SCAFFOLDING EFFECT
Reduce cognitive load
Saves willpower. For bad habits you want to break, don't set vague rules like "eat less sugar" (which is a willpower black hole); set clear boundaries like "no snacks with wrappers."
Anchor fast decisions
Using clear, written boundaries to delineate responsibilities, scope, and acceptable behavior, reducing friction and overstepping caused by ambiguity; it is the foundation of collaboration and governance.
