Abstract Through centuries and across continents, the singular condition which brings afflicted individuals in conflict with society is what might be broadly regarded as psychopathic disorder. Within the considerable body of knowledge amassed, the investigator who has indisputably made the most substantial contribution is Robert Hare, whose conceptualization of psychopathy is measurable as a superarching dimension and with subdimensions or factors and their facets. The instrument for identifying and measuring psychopathy, the Psychopathy Checklist-Revised (PCL-R), commonly regarded as the gold standard for psychopathy research (Westen & Weinberger, 2004), is widely used internationally for psychopathy research. Authors from four international domains – Germanic, Italian, Nordic and English – briefly describe the development of concepts of the psychopathic disorder, the influence of psychopathy as defined by Hare, as well as research and practical applications of PCL-R psychopathy and/or specific contributions concerning psychopathy within each of the domains. From the richness and diversity of investigative productivity within each of these domains, one can readily appreciate the impact of Hare’s work both within and between these major domains.
