Push for precision when acting on a wrong flag causes direct damage. A spam filter that buries a real invoice loses the user money. Auto-removing content or auto-blocking an account has the same shape: the false alarm is visible, immediate and hard to undo.
Recall wins when a miss is the expensive outcome and a false alarm is cheap to check. Disease screening is the classic case; a flagged patient gets a second test, but a missed tumor keeps growing. Security alerting and safety recalls follow the same logic.
The test that decides it is simple. Ask what happens after a positive prediction. If a human or a cheap second stage reviews every flag, push recall and accept noise. If the prediction acts on its own, protect precision, because nobody catches the mistake.
