The Modular Governance Model : Agency, Architecture, and the Three Regimes of the Self

The self that narrates a life is not always its author. This paper argues that coherent agency does not require psychological unity but governance, and its gravest failure is not always fragmentation but capture. The Modular Governance Model (MGM) holds that the mind is organized as functionally distinct modules — individuated by the register of their normative logic rather than by domain — operating under a regime that is Sovereign, Unstable, or Colonized. A Library of Introjects, assemblages installed through developmental and cultural imprinting, can serve authentic governance or seize it. In the Colonized Regime the affective core — the one module that cannot be rewritten — is gated out of governance, and an installed False Self occupies the cleared executive position, producing the first-person perspective with the full phenomenology of authenticity while the exiled module remains physiologically intact. Malignant narcissism is the paradigm case, and the architecture explains what symptom- and trait-based accounts do not: the systematic failure and 63–64% dropout of standard therapy, together with the narrow conditions under which change is nonetheless possible. MGM is continuous with computational psychiatry at the level of mechanism — colonization is the capture of precision-weighting — but adds a configurational claim that mechanism alone cannot express: that a learned structure can author the self from within. It reframes agency, authenticity, and therapeutic change as phenomena of governance rather than of diagnosis. It is a theoretical-architecture contribution: its predictions (§9) are stated to be falsifiable, but their empirical adjudication is future work.
