While the sociology of journalism has traditionally granted epistemic privilege to the mainstream news media, professional elites and their dominant meta-discourse, there is a recent trend to research journalism from other points of view. Researchers have investigated alternative and community media, journalists with low visibility or legitimacy in the workplace, as well as heterodox conceptions of professional excellence. These studies shed new light on little studied sub-groups and practices. How can we integrate them into a sustained scientific dialogue between researchers? This paper presents a methodologically original attempt to do so by dialogically re-interrogating material from studies of three situations where journalism absorbs precarious and politicised agents in the field (media activists), new practices and tasks that need doing (online discussion administration) and unusual kinds of professional attributes (experiencing emotionality in crisis reporting). In each case journalism’s pursuit of professional autonomy is at stake, since conditions of production clash with established professional myths and practices or generate incompatibilities with institutionalised expectations. Our three-way exchange using the bridging/sensitising concept of edge focuses on the conversion or convertibility of external forms of capital (legitimacies, resources and experiences) into forms redeemable and tradeable in a professional field. It exhibits how forces external to the journalistic profession are (made) present in each case but refracted differently in each local configuration. We call for a more systematic and relational study of these kinds of localised refractions.
