Exploring the differential contribution of boldness, meanness, and disinhibition to explain externalising and internalising behaviours across genders

Psychopathic personality traits are positively associated with externalising behaviours, and negatively associated with internalising behaviours. However, the contribution of different facets of psychopathy (boldness, meanness, disinhibition) in explaining externalising and internalising behaviours across genders are inconsistent. In this study, we explored gender differences in the assessment of, and relationships between, psychopathic personality traits, trait anxiety, social anxiety, depression, mental health, and aggressive behaviour in 822 students from a German University (586 women, 236 men; Mage = 22.27). Using a structural equation model, we found a positive relationship between aggressive behaviour and all three facets of psychopathy, a positive relationship between internalising behaviours and disinhibition, and a significant negative relationship between internalising behaviours and boldness. Despite gender differences in absolute levels of these variables, the overall pattern of the relationships between variables was consistent across genders. This indicates that symptom level differences across gender cannot be accounted for by variation in early developing personality traits like psychopathy

Aspects of psychopathic personality relate to lower subjective and objective professional success

Which aspects of psychopathic personality, if any, contribute to professional success? Previous research suggests that fearless dominance does so. Yet, it also suggests that self-centered impulsivity impairs professional success. Here, we address this differential pattern in a preregistered, multi-wave study involving a large, nationally representative sample (N = 2969 New Zealanders). We test the (a) replicability of prior findings using a new objective measure of professional success, and (b) stability of our findings across two annual assessments from 2011 and 2012. Fearless dominance is positively associated, but self-centered impulsivity is negatively associated, with subjective professional success. Controlling for age, gender, education level, and time in the current job does not alter these associations. Further, self-centered impulsivity and coldheartedness are negatively related with objective professional success. However, only the effect of coldheartedness remains after considering demographic variables. These relations hold for predicting subjective and objective professional success one year later. Together, aspects of psychopathic personality are linked negatively to objective professional success, a finding that challenges popular beliefs about the functional benefits of psychopathy in the workplace
