The Epistemic Floor: Institutional Conditions for Genuine Inclusion in Psychiatric Classification

Abstract The American Psychiatric Association is now designing the process that will produce the next iteration of the Diagnostic and Statistical Manual of Mental Disorders (DSM). Recent work on epistemic injustice in psychiatry converges on a shared diagnosis. The exclusion of psychopathologized perspectives undermines the social objectivity of psychiatric classification, and the literature leaves open how psychiatric science can engage with alternative interpretations of its domain without reducing them to the dominant framework. I propose four institutional conditions that inclusion must satisfy if it is to produce epistemic engagement and avoid tokenism. They are constitutive participation in agenda-setting and evidence evaluation, structural reproduction of participatory mechanisms across revision cycles, procedurally differentiated translation interfaces that preserve the critical content of non-standard perspectives, and bidirectional uptake with epistemic attitude and documented accountability. The conditions operate on the epistemic process that produces diagnostic categories without modifying the operational form those categories take, and are compatible with the functional requirements of the DSM and with the professional identity of psychiatry. They are designed to make inclusion structurally reproducible, where it has so far been contingently achievable, and they supply evaluative criteria for the design decisions the revision now confronts.
