Divergent thinking (DT) is the driver of the creative process. This study examined how DT was affected by the intensity level of the Creative Code, which consists of shared values held by people in creative departments of marketing communication agencies, about what represents excellence in advertising. A preliminary set of interviews with art directors, copywriters, and creative directors established a context and understanding of the importance of divergence, its role in the creative process, and methods that promote it. A national cross-sectional survey found a significant relationship between the Creative Code and divergence, which implied that divergent ideas could be fostered by more open communication among peers and with creative directors.
