Robert Hare is best known for developing the Hare Psychopathy Checklist-Revised (PCL-R), the most widely used and scientifically validated instrument for assessing psychopathy[reference:7][reference:8]. He is also the author of the influential book 'Without Conscience: The Disturbing World of the Psychopaths Among Us' (1993)[reference:9]. His research on the nature and assessment of psychopathy has established him as the foremost authority in the field[reference:10].

The Hare Psychopathy Checklist-Revised (PCL-R) is a 20-item clinical rating scale used to assess psychopathy in forensic and clinical settings[reference:11]. Items are scored on a 3-point scale and cover interpersonal, affective, and behavioral features such as manipulativeness, lack of empathy, impulsivity, and criminal versatility[reference:12]. It is considered the gold standard for psychopathy assessment and is a strong predictor of violent recidivism[reference:13].

Published in 1993, 'Without Conscience' is Robert Hare's landmark book that examines the disturbing world of psychopaths[reference:14]. Drawing on decades of scientific research, it profiles individuals who charm, manipulate, and exploit others without remorse[reference:15]. The book provides insights into the characteristics of psychopathy and offers guidance for understanding, evaluating, and dealing with these dangerous individuals[reference:16]. It has become a classic in forensic psychology.

Robert Hare's contributions to forensic psychology are foundational. He developed the PCL-R, the definitive tool for assessing psychopathy, which is used in risk assessment, sentencing, and parole decisions[reference:17]. His research has deepened understanding of the relationship between psychopathy and violent crime[reference:18]. He has also extended the study of psychopathy to corporate settings with the B-Scan-360[reference:19] and has advised law enforcement agencies including the FBI[reference:20].

Robert Hare has received numerous prestigious awards, including the Order of Canada (2011)[reference:21], the Canadian Psychological Association Gold Medal Award (2015)[reference:22], and the Isaac Ray Award from the American Psychiatric Association[reference:23]. He has also received the American Academy of Forensic Psychology Award for Distinguished Applications and a Lifetime Achievement Award from the Society for the Scientific Study of Psychopathy[reference:24].

Robert Hare was born in Calgary, Alberta, in 1934[reference:25]. He earned his BA and MA from the University of Alberta and his PhD in experimental psychology from the University of Western Ontario[reference:26]. He is Professor Emeritus of Psychology at the University of British Columbia, where he taught and conducted research for more than four decades[reference:27]. He is also President of Darkstone Research Group, a forensic research and consulting firm[reference:28].

Robert Hare has a long-standing advisory relationship with the FBI. He advises the FBI's Child Abduction and Serial Murder Investigative Resources Center (CASMIRC)[reference:29] and is a member of the FBI Serial Murder Working Group[reference:30]. He has consulted with the FBI and the RCMP on cases involving psychopathic offenders[reference:31], applying his research to assist in criminal investigations and profiling.

The B-Scan-360 is a 360-degree assessment instrument developed by Robert Hare and Paul Babiak to screen for psychopathic traits and behaviors in the corporate and business world[reference:32]. It is designed to help organizations identify individuals who may pose a risk due to manipulative, deceitful, or exploitative behaviors. This work extends Hare's research on psychopathy from criminal populations to the workplace, as explored in their book 'Snakes in Suits: When Psychopaths Go to Work'[reference:33].
