Argumentation
Influence as an object of research in social sciences and in communication (Mucchielli, 2009) mobilizes numerous definitions and approaches, putting at their center both the media (Maigret, 2015) and social interactions (Katz and Lazarsfeld, 1955). Through a more instrumental prism, we could say that exerting influence consists in getting others to freely do something that they would not have done spontaneously without a given intervention (Massé et al., 2006). Influence can also translate into the status quo, when the objective is, for example, to avoid mobilization (Gendron, 2014)
Influence can be conceived as the result of an act of communication on an audience’s behavior or social representations (Jodelet, 2003), as the result of a process of circulating ideas and opinions (Heath, 2006), or as a set of practices and strategies aimed at persuasion (Breton, 2008).
