The majority of empirical research on psychopathy involves forensic populations; however, researchers have recently turned their atention to the nature and implications of psychopathic features in the workplace, hence shedding light on the notion of "workplace psychopaths." Nowadays, many studies deal with successful people having a psychopathic outlook in a work environment. This is a contemporary phenomenon, originated during the 1990s. In this period, changing nature of work and business has created a general state of confusion due to increasing instability and competitiveness. In this social context, psychopathic personality aspects, such as the appearance of calm, conidence and other psychopathic tendencies, are mistaken for "leadership qualities."This contemporary phenomenon is dangerous and connected to psychosocial risks: the social and environmental contexts are afected by this dynamic, which can for instance lead to increasing anxiety in the co-workers and lack of motivation. This afects not only workers, but also companies: results of recent researches show the signiicant inluence of psychopaths on organizational commitment. These dynamics stimulated the interest of researchers in a variety of disciplines: psychiatry, as well as psychology, criminology, and sociology. This chapter aims at reviewing the current knowledge on this phenomenon, and to promote prevention and diagnosis.
