The Diagnosis is Not Wrong. The Map Is.

The persistent instability of psychiatric diagnosis — high comorbidity, within-category heterogeneity, endless DSM revision — reflects not empirical failure but a structural mismatch between the DSM's Aristotelian classification model and the ontological character of psychological suffering. Drawing on S.R. Ranganathan's faceted classification theory, phenomenological philosophy, and Bowker & Star's analysis of classification as social infrastructure, this essay argues for a faceted diagnostic framework as the operational logic that dimensional reform efforts like HiTOP and RDoC have been missing.
