Several genetic analyses of creativity have recently been reported. A key finding is that dopamine might be related to ideational fluency (Runco, Noble, Reiter-Palmon, Acar, Ritchie, & Yurkovich, 2011) or even to creativity per se (Reuter, Roth, Holve, & Hennig, 2006). Previous analyses have ignored an important part of genetic theory, however, namely the likelihood of polygenetic contributions. Many human characteristics are polygenetic.
