Nuanced HEXACO: A Meta-Analysis of HEXACO CrossRater Agreement, Heritability, and Rank-Order Stability

We replicated a meta-analysis showing that individual NEO-PI-R items – and their residuals after controlling for higher-order facets and domains – demonstrate sine qua non empirical properties of personality traits, hence representing personality nuances. Using the HEXACO-PI-R, we meta-analysed single-item cross-rater agreement, heritability, rank-order stability, and associations with age and sex in six countries (N = 9, 226), also correcting the estimates for short-term test-retest reliability. Median cross-rater agreement, heritability, and stability were, respectively, 0.30, 0.30, and 0.57 for raw item scores and 0.10 and 0.16, and 0.43 for their residuals ; these estimates increased to levels similar to domains after correction for measurement error. Moreover, 63% and 72% of raw items and 39% and 50% of their residuals, respectively, were significantly associated with age and sex. These findings were strikingly similar to those found in the previous meta-analysis, and provide further evidence that items index a unique level of the personality hierarchy.
