A study published in the International Journal of Psychology suggests that dark personality traits and flawed cognitive styles are separate risk factors for antisocial behavior. Although both were associated with rule-breaking, the researchers found no evidence that one pathway leads to the other.
The study examined the Dark Tetrad, a group of traits comprising psychopathy, narcissism, Machiavellianism, and sadism. Psychopathy involves low empathy and impulsivity, narcissism is associated with grandiosity and entitlement, Machiavellianism with manipulation and deceit, and sadism with deriving pleasure from others’ suffering.
Researchers led by Janko Mededović of the Institute of Criminological and Sociological Research in Belgrade surveyed 514 people, most of them university students, through online psychological assessments. Participants completed measures of Dark Tetrad traits, cognitive reflection, overconfidence, dichotomous thinking and self-reported antisocial behavior.
The cognitive reflection test used logic and math problems designed to prompt an intuitive but incorrect answer. Participants also estimated their performance on the test and rated themselves against the average person in areas including appearance, intellectual ability, emotional maturity and moral quality.
Sadism, psychopathy and Machiavellianism were associated with higher levels of reported rule-breaking, while narcissism was not a significant predictor in this sample. Participants who answered more logic problems incorrectly also reported more antisocial behavior.
Overconfidence showed a mixed pattern. Greater confidence in intellectual ability, physical appearance and performance on the logic test was linked to more rule-breaking. By contrast, participants who were more confident in their moral quality reported less antisocial behavior.
All four dark traits were associated with dichotomous thinking and overconfidence about physical appearance. Narcissism alone was linked to overconfidence in intellectual ability and social maturity. Meanwhile, people with higher levels of psychopathy, Machiavellianism and sadism showed less confidence in their moral quality, which the researchers said could reflect awareness that their values differ from conventional social standards.
The researchers then tested whether cognitive styles mediated the relationship between dark personality traits and antisocial behavior. The analysis found no mediation effect. The cognitive characteristics associated with dark traits were largely distinct from those associated with rule-breaking, indicating two independent psychological pathways.
The findings suggest that interventions aimed at improving logical reasoning and realistic self-assessment could be relevant when antisocial behavior is linked to poor decision-making habits. Such approaches may be less effective when behavior is primarily associated with dark personality traits.
The authors cautioned that the study’s participants were mainly university students, who generally report low levels of serious antisocial behavior. Its cross-sectional design cannot establish causation, and self-reported misconduct may be underreported or exaggerated. The researchers also noted that short assessment scales may have missed subtler effects. Future research could use official criminal records or experimental behavioral tasks to provide more objective measures.
