Abstract
Source of nomination (prosecution, defense, judge) was varied in a fictional not guilty by reason of insanity (NGRI) case distributed to 180 community forensic evaluators in a state employing theM'Naghten rule. Differences among examiners by appointment for the final NGRI judgment was not significant; interrater reliability for psychopathological symptomatology was .73. Discriminant analysis revealed significant differences in the decision-making process between evaluators recommending sanity and those endorsing insanity, as well as between psychiatrists and psychologists.
