Correct answer: E — Higher psychopathy scores are associated with increased risk of violent or dangerous outcomes, but do not determine whether an individual will be violent

Explanation lettering: E = shown as A · A = shown as B · D = shown as C · C = shown as D · B = shown as E

B is correct. Meta-analytic evidence demonstrates a meaningful positive association between psychopathy and dangerous outcomes, including violence and violent recidivism. However, the pooled relationship is imperfect and heterogeneous, so a high psychopathy score cannot establish that a particular person will become violent. It should contribute to a broader, individualised risk formulation rather than be interpreted deterministically. A and C contradict the observed positive association. D is incorrect because the relationship is not wholly attributable to substance misuse. E is also incorrect: although psychopathy components show differing associations across studies, meta-analysis indicates that antisocial-lifestyle or social-deviance features are generally more predictive of violence than the interpersonal-affective features alone.
