Abstract

Based on 95 years of data involving 320,051 patients, prisoners, students, and workers across 212 studies, there is a “7-point violence profile” (violence, deception, depression, antisocial behavior, paranoid or schizophrenic thinking, and addiction-alcoholism) on equations (Ask Standard Predictor of Violence Potential) and internet computer-scored tests (Minnesota Multiphasic Personality Inventory [MMPI-2/A]) that is similar for male or female, adult, or teen, violence prone or suicidal. Using conventional methods, traditional decision-makers believe that their 39% success rate in finding violence-prone individuals is better than the 97% hit rate of equations and computer tests. Given the $3,834,988.08 cost of 1 killer (2021 US$), lawyers can lead in broadening the liability net to include all who should predict or prevent violence-prone events to save US yearly $13,000,000,000 and 471,000 victims. When a critical mass of attorneys and victims collect payouts resulting in higher insurance and taxes, decision-makers will enthusiastically embrace equations and computer tests.
