Transgenerational Trauma as Inherited Displacement Basin: Epigenetic Encoding, Cultural Transmission, and the Return Path Through Witnessed Repair

Transgenerational trauma — the transmission of trauma sequelae across generations through epigenetic, psychological, and cultural channels — is here formally reconceptualized as an inherited displacement basin. The original traumatic generation accumulates Phi that is not fully discharged; this residual displacement is transmitted to subsequent generations as elevated baseline displacement cost, a lowered return threshold, and specific wrong attractor geometries.

Nine formal propositions characterize epigenetic inheritance (Yehuda's cortisol dysregulation findings), psychological transmission through attachment disruption and parenting patterns (Fraiberg's ghosts in the nursery), cultural transmission through silence and narrative (Danieli's conspiracy of silence), collective trauma in Indigenous communities and descendants of slavery, second-generation phenomenology, and return paths through witnessed repair, intergenerational therapy, and cultural healing practices.
