A factor analysis of creativity in fraternal and identical twins

The relationship between intelligence and creativity and their factorial structure have been extensively discussed, with little empirical evidence and less agreement as to the meaning. A study of 117 pairs of like sexed fraternal and identical twins was undertaken, with each twin participating in an extensive battery of creativity tests.A factor analysis indicated three factors for the fraternal twins and two for the identical twins, the results supporting both (a) the notion that the common variance of creativity measures may be accounted for by a general intelligence factor, and (b) the division of creativity into a verbal and a figural domain.
