Every filter fails in two directions
Every filter makes two kinds of mistake: it passes noise (a false positive) or it blocks signal (a false negative). Signal detection theory proves you cannot minimize both with one filter — tightening against one failure loosens the other. Filtering skill is not building a perfect filter; it is choosing, per filter, which failure is cheap and which is catastrophic, and tuning toward the cheap one.
False positive triggers
When a trigger fires in the wrong context you need to add qualifying conditions.
A gate that cries wolf becomes noise
Validation gates are themselves signal sources — and a gate with a high false-alarm rate becomes a noise source that trains you to ignore it. Aviation and intensive care call the result alarm fatigue, and it kills. A self-healing filter network therefore needs a meta-gate: every gate's alarms get logged, its false-positive rate reviewed, and chronic criers retuned or removed. The system must audit not just its contents but its own filters.
Emotional false positives
Sometimes your emotional system fires when there is no real threat — evaluate before acting.
