Diagnostic reasoning is a structured inferential practice that identifies causes or conditions from observed evidence. Parameters: (1) symptom/data set — the observations to be explained; (2) differential — the set of candidate causes or conditions; (3) decision criterion — the standard for selecting the best explanation (most likely, most actionable, most parsimonious); (4) feedback loop — validation against outcomes to refine future diagnostic accuracy. Persistence mechanism: institutionalized training in medical and technical education, standardized diagnostic manuals (ICD, DSM), and algorithmic decision-support systems.
