An AI model's ability to predict risk is only part of the equation; the crucial step of deciding when to act based on those predictions is a human responsibility. Even a model with strong performance metrics like an AUROC of 0.84 and good calibration can lead to poor outcomes if the decision threshold is set inappropriately. The author demonstrates that a default threshold of 0.5 missed a significant portion of actual cases, highlighting the need for careful consideration of consequences when translating AI-generated probabilities into actionable decisions. AI
