This paper investigates the dissemination of scientific concepts and ideas through a focus on extra-scientific factors. While scientific progress is usually evaluated in terms of intellectual achievement of the individual researcher, we tend to forget about the external factors that tacitly yet critically contribute to knowledge production. While these externalities are well-documented in the natural sciences, social sciences have not yet seen comparable scrutiny. Using Torsten Hägerstrand’s rise to prominence as a concrete example, we explore this perspective in a social-science case – human geography. Applying an STS (Science and Technology Studies) approach, we depart from a model of science as socially-materially contingent, with special focus being put on three extra-scientific factors: community norms, materiality and the political climate. Echoing Annemarie Mol, we conclude it is these types of conditions that in practice escape the relativism of representation.
