Abstract Several studies have investigated the relations between cognitive ability and Big Five personality constructs. The present study extended previous research by (a) examining these relationships in large samples (total N = 120,014), (b) including several measures of cognitive ability and personality, (c) examining both domain and facet‐level personality scores, (d) expanding the personality domains studied to include Machiavellianism, and (e) correcting the observed correlations for range restriction and reliability to provide a better statistical estimate of the relations between the cognitive and personality scores and constructs. Results were consistent with prior research showing a positive relationship between cognitive ability and Openness and negative relationships between cognitive ability and Neuroticism and Conscientiousness. Negative relations between cognitive ability and Extraversion and Agreeableness also were observed. Machiavellianism, not part of the Big Five was found to have a positive correlation with cognitive ability. Of particular interest was the finding that the relations between cognitive ability and personality were affected by the specific content of the cognitive and personality measures. Cognitive measures with verbal content were more strongly correlated with personality than were cognitive measures with math or nonverbal content for all of the samples. Also, there was considerable variability in the cognitive‐personality correlations for the facets underlying each personality domain. The variability in correlations at the facet‐level implies that cognitive‐personality relationships at the domain‐level will vary as a function of the specific content of the cognitive and personality measures. Overall, the results provide support for cognitive‐personality association at the measurement level.
