When groups are asked to think creatively the reason they frequently fail is because implicit norms constrain them in the most explicit ways. This is clearly demonstrated in a recent study carried out by Adarves-Yorno et al. (2006). They asked two groups of participants to create posters and subtly gave each group a norm about either using more words on the poster or more images.
Afterwards when they judged each others’ work, participants equated creativity with following the group norm; the ‘words’ group rated posters with more words as more creative and the ‘images’ group rated posters with more images as more creative. The unwritten rules of the group, therefore, determined what its members considered creative. In effect groups had redefined creativity as conformity.
