Scholarcy highlights

  • A robust literature has emerged on the Dark Triad of personality—Machiavellianism, psychopathy, and narcissism
  • In Studies 1 and 2, DT scores were examined in relation to a variety of external criteria, including self- and informant ratings of personality, adverse developmental experiences, and psychopathological symptoms/behaviors
  • MACH and psychopathy manifested nearly identical empirical profiles and both were significantly related to disinhibitory traits thought to be antithetical to MACH
  • Measures of psychopathy and MACH appear to be measuring the same construct, and MACH assessments fail to capture the construct as articulated in theoretical descriptions
