We apply the Displacement Framework to Body Dysmorphic Disorder (BDD), formalizing it as W_BDD — a wrong attractor organized around the perceived defect belief, a fixed self-reinforcing preoccupation with a specific body feature (absent or minimal to objective observers) that generates repetitive compulsive behaviors which paradoxically deepen rather than resolve the preoccupation.
The body self-perception ground state S⁰_body is defined as proportionate, roughly accurate body image without disproportionate distress or compulsive behavioral response. W_BDD is maintained by three interlocking mechanisms: the perceived defect core belief (P_defect), the compulsive checking loop (mirror checking, camouflaging, reassurance seeking, skin picking — each providing momentary D(ξ) relief followed by amplified preoccupation), and camouflage/avoidance preventing disconfirmatory social feedback.
Nine formal propositions cover: S⁰_body definition (P1), W_BDD architecture with OCD-spectrum structural identity (P2), the compulsive checking loop as wrong attractor maintenance (P3), the insight spectrum as basin depth marker — good insight (overvalued idea) permits ERP access while poor/absent insight approaches delusional basin depth (P4), camouflage and avoidance as basin reinforcers (P5), cumulative Φ_BDD across social, occupational, and relationship domains (P6), suicide risk as maximum D(ξ) endpoint — BDD has ~45% lifetime suicidal ideation and among the highest suicide rates of any psychiatric condition (P7), CBT with ERP as primary return path with SSRI augmentation (P8), and the cosmetic surgery contraindication — surgery deepens W_BDD through symptom transfer in ~80% of cases (P9).
Muscle dysmorphia is formalized as BDD variant; social media amplification of BDD is analyzed.
