"The expression distributed creativity refers to the diffusion of creative behaviours in the society. It is based on very different phenomena: form the diffusion of ‘creative professions’, to the one of diffused innovators , to the one creative communities . More in general, this kind of diffused creativity can be seen as an expression of the “normal" condition of individuals in the present society where, to face their daily life choices, they have to develop specific entrepreneurial and design capabilities (cfr. Giddens and Beck)."
