The present study investigates in an adult sample (N = 220) whether the relationships between the Five-Factor Model personality dimensions and punitive attitudes (i.e., deterrence, desert, moral balance, incapacitation, and rehabilitation) are mediated by right-wing attitudes (i.e., Right-Wing Authoritarianism and Social Dominance Orientation). Three important results were obtained. First, the specific punitive attitudes referred to three higher order dimensions:Harsh Punishment, Social-Constructive treatment and Moral balance. Second, Harsh Punishment was largely driven by right-wing attitudes and broadband personality traits.Furthermore, RWA fully mediated the effect of Neuroticism, while the effects of Openness to Experience and Extraversion were only partially mediated. Third, Social-Constructiveness and Moral balance were only poorly related to broadband personality and right-wing attitudes.Strengths and limitations are discussed, as well as implications for punitive policies.
