Divergent Thinking (DT) is an important constituent of creativity that captures aspects of fluency and originality. The literature lacks multivariate studies that report the relations between DT and its aspects with important covariates, such as cognitive abilities, personality traits (e.g., openness), and insight. In two multivariate studies (N = 152 and N = 298), we evaluate competing measurement models for a variety of DT tests and examine the relation between DT and established cognitive abilities, personality traits, and insight. A bifactor model with a general DT and a nested originality factor best described the data. In Study 1, DT and originality were moderately related with working memory, fluid intelligence, crystallized intelligence, and mental speed. In Study 2, we replicate these results and add insight, openness, extraversion, and honesty-humility as covariates. DT was associated with insight, extraversion, and honesty-humility, whereas crystallized intelligence mediated the relationship between openness and DT. In contrast, originality was neither related to personality traits nor to cognitive abilities. In sum, the nested originality factor had low variance and was not meaningfully related with any other constructs in the nomological net. We highlight avenues for future research by discussing issues of measurement and scoring.
