In this video, Dr. Ettensohn examines the growing claim that Narcissistic Personality Disorder (NPD) is almost entirely genetic, offering a critical, clinically grounded reflection on what the current science actually supports—and where it falls short. He discusses how genetic contributions to personality traits are often misunderstood, and why claims of “hardwired narcissism” oversimplify a profoundly complex developmental process.
Drawing from empirical research, neurodevelopmental theory, and clinical observation, Dr. Ettensohn explores how narcissistic pathology emerges not simply from temperament, but from early relational experiences—especially chronic emotional neglect, inconsistent attunement, and conditional regard. He addresses how brain plasticity, diagnostic controversies, and the misunderstood vulnerable core of NPD further complicate the genetic narrative.
This video offers a nuanced perspective for anyone seeking to understand NPD beyond reductive models, emphasizing the importance of relational context, developmental history, and psychological depth.
