Course Overview

  • Charles Manson gained notoriety for orchestrating the “Tate–LaBianca” murders of seven individuals in August 1969, for which he received the death penalty in 1971. The death penalty was invalidated in 1972 by the U.S. Supreme Court. He served out his life sentence in the California Department of Corrections until his death in 2017 at the age of 83. During the course of his confinement, Manson was evaluated many times by psychiatrists and psychologists. His diagnoses ranged from various personality disorders to schizophrenia, undifferentiated type. In August 1997, Manson was transferred to Pelican Bay State Prison to serve a Secure Housing Unit term for a serious rule infraction. A comprehensive psychological evaluation was conducted using the Rorschach, the MMPI-2, WAIS-R Similarities and Vocabulary subtests, WRAT-R, TONI-2, and PCL-R. This 1997 evaluation and test results became publicly available after Manson’s death in 2017, the first known existence of psychological test data from Charles Manson. The main focus of this first article on which Dr. Mihura was a co-author was assessing Manson for schizophrenia.

    Dr. Mihura, discusses the blind rescoring of Manson’s Rorschach protocol using R-PAS—that was originally using the Comprehensive System—and the implications related to Manson’s diagnosis of schizophrenia. She also compares the CS interpretation to the R-PAS interpretation in regard to the implications for diagnosing psychotic disorders, schizophrenia in particular. The presenter discusses the findings presented in “The Last Psychological Evaluation of Charles Manson: Implications for Personality, Psychopathology, and Ideology” by Roy, Mihura, Friedman, Nichols, and Meloy (2022) as well as an interview with Diane Sawyer and its implications for thought disorder. Attendees are not required to have expertise in assessing psychosis nor R-PAS.
