Creativity and flexiblity

Herrmann ties creativity to all four quadrants.

A study published in the peer reviewed Creativity Research Journal in 2005 by J. Meneely and M. Portillo agreed that creativity is not localized into a particular thinking style, such as a right-brain dominance resulting in more creativity. They did however find correlation between creativity in design students based on how flexible they were using all four thinking styles equally as measured by the HBDI. When students were less entrenched in a specific style of thinking they measured higher creativity using Domino’s Creativity Scale (ACL-Cr). Therefore, they found training thinking styles associated by Herrmann as right hemisphere did not necessarily improve creativity, but training in thinking styles that measured less strongly in the instrument would produce greater creativity.
