ObjectiveThe extensive use of two diverging personality taxonomies (the Big Five and HEXACO models) in contemporary research creates a need for understanding how traits connect to each other across taxonomies. Previous research has approached this at both a highly general (domain‐) level as well as at a highly specific (facet‐) level. The present report is the first to use the intermediate (aspect‐) level of the Big Five Aspect Scales (BFAS) to understand the connections between the two models.MethodWe explored these associations in a meta‐analysis of four samples drawn from three countries (total N = 1,586).ResultsWe observed that each HEXACO domain correlated ≥|0.51| with one or more BFAS aspects. Half of the aspects were more strongly associated with HEXACO facets than with HEXACO domains, sometimes markedly so.ConclusionAlthough many domains, aspects, and facets are similarly represented across the two models, this was not always the case. Researchers seeking to use one model to extend findings built primarily off the other should carefully consider how well represented their traits of interest are in the other assessment. Psychology instructors are encouraged to use the BFAS to illustrate the subtler distinctions between the Big Five and HEXACO models.

Using the HEXACO Model of Personality, we explored two kinds of ideal partner preferences regarding personality traits, namely, to what extent people prefer partners similar to themselves (similarity preference) and to what extent people prefer partners with more desirable trait levels than themselves (aspirational assortative preference). We conducted five studies (overall N > 900) across four countries (China, Denmark, Germany, and the USA), looking at both HEXACO factors and facets, using both self‐report questionnaires and real‐life data (personal profiles from a dating website), and comprising both student and more heterogeneous samples. The results provided support for both kinds of ideal partner preferences, with important differences across traits. Specifically, similarity preference was supported by all studies concerning all HEXACO traits, and aspirational assortative preference was supported by all four self‐report studies (though not the dating website study) concerning all HEXACO traits except for Openness to Experience. Concerning differences in preferences among the HEXACO traits, similarity preference was particularly pronounced for Honesty–Humility and Openness to Experience, moderate for Agreeableness and Conscientiousness, and less pronounced for Emotionality and Extraversion. Aspirational assortative preference, by contrast, was particularly pronounced for Emotionality, Extraversion, and Agreeableness, moderate for Honesty–Humility, and inconsistent for Conscientiousness. © 2018 European Association of Personality Psychology

Abstract. In this study, we investigated the interaction effects between honesty-humility and two contextual perception variables (perceptions of organizational politics and perceptions of interactional justice) on two dimensions of job performance (task performance and organizational citizenship behavior). In a multiple rater design, we dissociated the assessments of the contextual perception variables (rated by target employees), personality traits (rated by colleagues), and job performance (rated by supervisors) from each other. We expected employees lower in honesty-humility to adapt their behavior according to the perceived context, whereas employees higher in honesty-humility were expected to perform equally well irrespective of the perceived environment. Results supported the hypothesized interactions in general.
