This study provides a comprehensive assessment of the associations of personality and intelligence. It presents a meta-analysis (N = 162,636, k = 272) of domain, facet, and item-level correlations between personality and intelligence (general, fluid, and crystallized) for the major Big Five and HEXACO hierarchical frameworks of personality: NEO Personality Inventory–Revised, Big Five Aspect Scales, Big Five Inventory–2, and HEXACO Personality Inventory–Revised. It provides the first meta-analysis of personality and intelligence to comprehensively examine (a) facet-level correlations for these hierarchical frameworks of personality, (b) item-level correlations, (c) domain- and facet-level predictive models. Age and sex differences in personality and intelligence, and study-level moderators, are also examined. The study was complemented by four of our own unpublished data sets (N = 26,813) which were used to assess the ability of item-level models to provide generalizable prediction. Results showed that openness (ρ = .20) and neuroticism (ρ = −.09) were the strongest Big Five correlates of intelligence and that openness correlated more with crystallized than fluid intelligence. At the facet level, traits related to intellectual engagement and unconventionality were more strongly related to intelligence than other openness facets, and sociability and orderliness were negatively correlated with intelligence. Facets of gregariousness and excitement seeking had stronger negative correlations, and openness to aesthetics, feelings, and values had stronger positive correlations with crystallized than fluid intelligence. Facets explained more than twice the variance of domains. Overall, the results provide the most nuanced and robust evidence to date of the relationship between personality and intelligence.

人格与智力：荟萃分析。

这项研究对人格和智力的关联进行了全面评估。它对主要的 Big Five 和 HEXACO 人格层次框架：NEO人格量表 - 修订版、大五方面量表、大五量表 - 2 和 HEXACO 人格量表 - 修订版。它提供了第一个关于人格和智力的元分析，以全面检查（a）这些人格层次框架的方面级相关性，（b）项目级相关性，（c）领域和方面级预测模型。还检查了人格和智力的年龄和性别差异，以及研究水平的调节者。该研究得到了我们自己的四个未发表的数据集 (N = 26,813) 的补充，这些数据集用于评估项目级模型提供可概括预测的能力。结果表明，开放性 (ρ = .20) 和神经质 (ρ = -.09) 是最强的大五智力相关因素，并且开放性与结晶智力的相关性高于流体智力。在方面层面，与智力投入和非常规相关的特征与智力的相关性比其他开放方面更强烈，社交能力和秩序与智力呈负相关。合群性和寻求兴奋的方面具有更强的负相关性，而对审美、情感和价值观的开放性与结晶智力比流体智力具有更强的正相关性。方面解释了域方差的两倍以上。总体而言，这些结果为人格与智力之间的关系提供了迄今为止最细微和最有力的证据。
