Both traits represent key correlates of life outcomes, predicting everything from occupational and economic success, to various indicators of prosocial and antisocial behaviour. The findings to date regarding the association of the two traits, however, have been somewhat inconsistent. Moreover, there has been a tendency to confuse psychopathy with other clinically significant disorders, which also predict antisocial behaviour. Thus, there remains a need for a more systematic investigation of the extant empirical literature. The current study represents a meta-analysis conducted to evaluate the direction and overall effect size between these traits: intelligence, psychopathy, and antisocial or conduct-related disorders. In a pooled sample of 27,094 participants from 105 correlations, our analyses revealed a small, statistically significant, relationship between intelligence and psychopathy (r = -.07, p = .001). Furthermore, we analysed the relationship between intelligence and antisocial disorders, finding a modest, inverse relationship for Antisocial Personality Disorder (r = -.13, p = .001; n = 2,151; k = 14) and Conduct Disorder (r = -.11; n = 23,171; k = 23), but a small, positive association for Oppositional Defiant Disorder (r = .06, p = .001; n = 10,362; k = 3).}, URL = {https://www.biorxiv.org/content/early/2018/01/16/100693}, eprint = {https://www.biorxiv.org/content/early/2018/01/16/100693.full.pdf}, journal = {bioRxiv} }
