PhronesisWe apply the Displacement Framework to Dissociative Identity Disorder (DID), formalizing it as landscape fragmentation — a trauma-induced split of the unified identity landscape into multiple disconnected basins rather than a single wrong attractor. The unified identity ground state S°_self is defined across five axes: narrative continuity, integrated memory and affect access, single locus of agency, unified threat response, and stable bodily ownership.
Severe chronic childhood abuse before age 9 fractures this landscape through van der Hart's structural dissociation cascade (primary → secondary → tertiary splitting), with amnestic barriers formalized as energy barriers between basins. Each alter state is a wrong attractor W_i with its own identity, affect, trauma memory access, and documented physiological signature. Nine formal propositions are derived covering: S°_self as unified basin (P1), basin-splitting as fragmentation rather than displacement (P2), the protective function of fragmentation (Φ distributed across n alters, each bearing Φ_i = Φ_total/n · k_i rather than full cumulative load) (P3), the adaptive-to-pathological transition under post-trauma conditions (P4), alter states as parallel wrong attractors with amnestic barriers as inter-basin energy walls (P5), cumulative Φ_system across functional amnesia, internal conflict, relational discontinuity, and occupational impairment (P6), ISSTD three-phase treatment as sequential basin merging toward re-unified landscape (P7), the integration-vs-elimination distinction (P8), and the dissociative spectrum placement of DID as most severe structural fragmentation (P9).
The paper formally distinguishes DID from BPD (topology vs. depth), from C-PTSD, and comprehensively rebuts malingering claims through the DF architecture.
