  - In life-threatening screening, missing a true positive (a real cancer case) is far more costly than a false alarm that gets investigated further. Therefore the model should be tuned for high recall (also called sensitivity) — finding all true positives, even at the cost of more false positives. Spam filters or fraud alerts that should not bother users typically tune for high precision instead.
