The widespread popularity of true crime media has generated substantial scholarly interest regarding its psychological and cultural underpinnings. Although audiences from diverse demographic backgrounds consume true crime content, evidence suggests that individuals with Cluster B personality traits—narcissistic, borderline, histrionic, and antisocial—display a particularly pronounced attraction. This article investigates the relationship between Cluster B pathology and true crime fascination by synthesizing existing psychological theory, clinical research, and media studies. We argue that this affinity is underpinned by heightened emotional intensity, identification with both victims and perpetrators, reinforcement of maladaptive worldviews, and opportunities for self-regulation through mediated exposure to danger. In examining these processes, the paper highlights how true crime functions simultaneously as a mirror of pathological dynamics and a cultural tool for negotiating fear, identity, and control.
