Science popularisation as diffusion of knowledge?

Abstract

This article offers an in-depth analysis of the diffusion model of science popularisation. It reviews criticisms against the model and shows that they do not warrant its rejection. It argues that the diffusion model has elements, hitherto neglected, which can facilitate a better understanding of popularisation. Viewing popularisation as the diffusion of knowledge is beneficial because it enables us to: (1) pinpoint the origins of popularisation and trace its historical continuity; (2) explain why science requires continuous popularisation; (3) understand why the values that popularisers promote are not arbitrary; and (4) define more precisely the role of popularisers.
