Third NCA study replicates the finding that intelligence is necessary for creativity

A third study that uses NCA to test the hypothesis that intelligence is necessary for creativity was published in the journal Intelligence. The abstract says: " This paper explores longitudinal links between intelligence measured at age 11 (N = 1594) and 13 (N = 255) and creative achievement as tested forty years later (at age 52). Using a dataset from the most recent (fifth: 2015) follow-up to the Warsaw Study (Firkowska et al., 1978), we examined the hypothesis that intelligence forms a necessary-yet-not-sufficient condition for creative achievement. Although the links between intelligence and creativity as estimated with the use of linear (correlations) and nonlinear (segmented regression) analytical methods were generally ambiguous, the recently developed Necessary Condition Analysis (NCA, Dul, 2016a) presented a much clearer pattern demonstrating that high creative middle-age achievement was unlikely with low intelligence in childhood. The strength of the NCA effect size was moderated by the domain of creativity, being higher for cognitively demanding domains (science, inventions, humor, architecture, or writing) than for artistic or everyday domains (cooking, dance, music, visual arts or theatre).
