The relationship between intelligence and creativity remains controversial. The present research explored this issue by studying the role of fluid intelligence (Gf) in the generation of creative metaphors. Participants (n = 132 young adults) completed six nonverbal tests of Gf (primarily tests of inductive reasoning) and were then asked to create metaphors that described a past emotional experience. The metaphors were rated for creative quality. Latent variable models found that Gf explained approximately 24% of the variance in metaphor quality (standardized beta = .49), consistent with the view that creative ideation engages executive processes and abilities. The effect of Gf remained substantial after including personality (the Big Five factors) in the model. The discussion considers implications for the debate over intelligence and creativity as well as for the cognitive abilities involved in metaphor production. Are intelligent people more creative, or are intelligence and creativity independent abilities? This question is one of the enduring controversies in the psychology of creativity (Kaufman, 2009 andWallach andKogan, 1965). In the present work, we take a new slant on this problem by examining the role of fluid intelligence (Gf) in the production of creative metaphors. This work extends studies of creative cognition to a new domain, provides further support for our view that intelligence is central to creative thought (Nusbaum & Silvia, 2011a), and contributes to the emerging literature on how people make metaphors (Chiappe & Chiappe, 2007).
