Principlev1
Evaluate behaviors based on their worst-case performance,
Evaluate behaviors based on their worst-case performance, not their best-case or average performance, to distinguish genuine automation from condition-dependent reliability.
Why This Is a Principle
Derives from Directed Attention as Depletable Resource (cognitive resources deplete under stress) and Human memory under stress and cognitive load is unreliable (memory under stress is unreliable). The principle prescribes a diagnostic method: test automation under adverse conditions since that reveals structural robustness versus environmental dependency.
