Invest in preventing error-producing conditions rather…

Why This Is a Principle

This principle derives from Directed Attention as Depletable Resource (finite cognitive resources), The behavior of a system arises from its structure… (system behavior arises from structure), and Every system is perfectly designed to get the results… (systems are designed to get their results). It prescribes a strategic allocation: reduce error rate at source rather than increasing correction efficiency. This follows from multiple axioms about costs and system design but is itself a design principle, not a base truth.
