Signal detection involves independent dimensions of
Signal detection involves independent dimensions of sensitivity and specificity.
Why This Is an Axiom
This is signal detection theory (Green & Swets, 1966) — a theoretical framework the curriculum adopts wholesale. The claim that hits/misses and false alarms/correct rejections represent orthogonal performance dimensions is foundational and not derivable from other axioms. It's the framework through which reliability is understood.
Source Lessons
L-0545
Agent reliability metrics
Track how often each agent fires when it should and does not fire when it should not.
L-0431
Missed triggers
When you fail to notice a trigger you need to make it more salient.
L-0548
False positive rate
An agent that fires when it shouldn't wastes your attention and erodes trust.
L-0555
Alert thresholds
Define clear thresholds that distinguish normal operation from problems requiring your attention.
L-0423
Reliable triggers are specific and observable
A trigger must be something you can detect consistently.
