The concept of the addictive personality occupies contested terrain within the depth-psychology corpus. No consensus obtains: the term functions variously as a clinical heuristic, a stigmatizing social construction, and a phenomenological marker pointing toward deeper structural deficits of the self. Gabor Maté, whose clinical immersion in Vancouver’s Downtown Eastside shapes his account most powerfully, dissolves the addictive personality into a set of developmental failures — impaired self-regulation, deficient differentiation, a chronic inner emptiness — while simultaneously warning that what we name ‘personality’ may itself be a defensive fiction papering over the loss of authentic selfhood. Philip Flores, working from psychodynamic and object-relations ground, places the addictive personality within a larger architecture of self-defect and narcissistic disturbance, arguing that apparent personality pathology in active addiction is often secondary to substance effects rather than primary character structure. Stella Dennett mounts the most direct critique, dismissing the concept as a socially constructed ideology rooted in the DSM’s early and now-abandoned classification of addiction under personality disorders. Marc Lewis, from a neurobiological constructivist standpoint, reframes what clinicians call addictive personality traits — impulsivity, delay discounting, now-appeal — as developmental trajectories rather than fixed types. The Jungian thread, visible in Schoen and Dennett alike, recasts personality transformation in addiction through the lens of shadow, the Dr. Jekyll/Mr. Hyde polarity, and the persona’s collapse under the pressure of unconscious forces.
