The relationship between creativity and general cognitive ability ( g ) has long been debated. This study investigates the genetic basis of creative achievement and its overlap with intelligence, expanding the traditional scope of creativity beyond art and science to include enterprising domains (business, military, and politics). Using a twin study design, we analyzed data from 2,141 twins who completed an extended Creative Achievement Questionnaire (CAQ) and three tests of cognitive ability. Enterprising Creativity – strategic manipulating of human systems and resources – emerged as a valuable extension to the CAQ. Structural equation modeling evaluated competing hypotheses of genetic independence, complete overlap, or partial overlap between the constructs. Creative achievement was found to be heritable (h² = .56), with shared environmental influences estimated at zero. A latent creativity factor independent of general cognitive ability (rg = 0) loaded on artistic, scientific, and enterprising domains; residual genetic paths from g to the observed creativity measures were small (.29) or non-significant (–.08 for art). The study thus supports creativity as an independent latent trait, as well as the value of g , especially in science and enterprising creativity on specific achievement.
