Set detection thresholds based on the relative costs of false positives versus false negatives rather than maximizing either sensitivity or specificity alone.
Why This Is a Principle
This derives directly from Signal detection involves independent dimensions… (signal detection has independent dimensions of sensitivity and specificity) and Every detection system faces a fundamental tradeoff between… (the fundamental tradeoff between catching real signals and false alarms). It provides actionable guidance for calibrating any detection system—not just information filters but any decision threshold. It's prescriptive and derived, not foundational.
