A model’s most likely prediction is not automatically the best decision. The costs of errors and the available alternatives matter.

• Separate evidence, prediction, and action policy.
• Evaluate the consequences of both error types.
• Keep responsibility and correction procedures explicit.

Separate the stages of the decision. Identify what is observed, what the model estimates, what rule turns that estimate into an action, and who is accountable for the result. This makes it possible to challenge the evidence or policy independently of the model. Evaluate both error directions and the option to defer. A false alarm may create review work; a missed event may leave a problem unresolved. The appropriate threshold depends on those consequences, capacity, and the reliability of the score. Consider how the action changes later data. If a system only records outcomes for cases it selects, future training data can reflect its own past choices. Apparent improvement may result from changed measurement rather than better decisions. For consequential decisions, retain appropriate expert oversight, explanations grounded in actual evidence, and a way to correct mistakes. A generic model confidence statement is not a substitute for an applicable policy or a person’s right to question an outcome. Test the complete workflow under the conditions where it will be used.

1. In an illustrative equipment-monitoring task, an unnecessary inspection costs 10 units, while missing a failure costs 1,000 units.
2. A threshold selected only to maximize accuracy ignores this asymmetry. Compare expected consequences using validated probabilities and representative outcomes.
3. Include the cost and feasibility of inspection, plus uncertainty about those estimates, before choosing a policy.

This invented example explains why a decision needs more than the most likely class.
