INTRODUCTION

CORE DEFINITION

Non-Overlapping Magisteria, or NOMA, is a principle proposed by Stephen Jay Gould in Rocks of Ages. Science holds authority over the empirical realm, what the world is made of and how it works, while religion holds authority over value and meaning, what we ought to do. Neither should legislate inside the other's domain. In organizations the same split separates factual judgment from value judgment, so data settles what is, and purpose settles what should be.

SCAFFOLDING EFFECT

Reduce cognitive load

- Domain Boundary Mapping: sort a disputed question into fact, value, or a mix before arguing. - Single Owner Rule: assign each decision to exactly one accountable authority to prevent overlap. - Value Conflict Handling: keep vision out of data debates and evidence out of purpose debates.

Overlapping authority produces blame-shifting and unresolvable disputes, because two bodies can each claim final say. Assigning each class of question to a single authority makes decisions attributable, so disputes resolve by domain rather than by power and accountability has a clear owner.

Single Threaded Leader

For important projects, a leader must be assigned who is responsible for nothing else (single-threaded), fully owns the success or failure of the project, and has the authority to mobilize resources, rather than relying on cross-departmental collaboration (which is often inefficient).
