Pathological lying has rarely appeared on the psychiatric radar screen in recent years, remaining a poorly understood concept with serious ramifications, particularly for forensic psychiatrists.Ĭharles Dike, M.D., a forensic psychiatrist and clinical instructor in psychiatry at Yale University School of Medicine, maintains that psychiatrists need to pay attention to pathological lying so they are able to inform the legal system about whether pathological liars should be held responsible for their behavior.
