How are intelligence and creativity related? Given the dynamic and complex nature of both constructs, this question is a nuanced one. This chapter first discusses how creativity is represented in intelligence theories (such as Guilford’s Structure of Intellect, CHC, and successful intelligence, and how intelligence is represented in creativity theories (such as systems and componential theories, domain-based theories, and cognitive theories). Next, empirical studies are reviewed. The threshold theory, which proposes that intelligence and creativity are related but only up to about an IQ of 120, has received mixed support. More recent studies using sophisticated statistical analyses have found more evidence. A reliance on measures of divergent thinking and g as the sole tests of creativity and intelligence may also limit much existing research.
