NAPD - The Dark Tetrad: A forensic neuroscience and neurocriminological perspective


Time: February 9, 2026 - 1-2pm
Location: Webinar

The Dark Tetrad is a constellation of four interrelated personality traits: narcissism, psychopathy, Machiavellianism, and sadism. These four traits are typified by grandiosity, manipulativeness, lack of empathy, and indifference to the well-being of others. The Dark Tetrad is linked to a diverse array of negative outcomes, including poor social relationships, career instability, and problematic or criminal behaviors. Research suggests that these traits are influenced, at least in part, by prenatal and postnatal neurobiopsychosocial factors. As such, neurocriminology provides a critical pathway for understanding the role of brain structure, brain function, and biochemical and genetic factors in the etiology of the Dark Tetrad. Further, forensic neuroscience can apply these neurocriminological findings to evaluate key psycholegal concepts and processes. Designed for criminal justice, forensic mental health, and legal professionals, this training explores the characteristics and causes of each Dark Tetrad trait through the lenses of forensic neuroscience and neurocriminology. Attendees will learn how these approaches can help enhance understanding, prevention, screening and assessment, interventions, and management of these traits. Cutting-edge research findings and compelling case studies will be presented throughout to illustrate key topics.
