 Argumentation can be defined as the communicative activity of producing and exchanging reasons in order to support claims or defend/challenge positions, especially in situations of doubt or disagreement (Lewiński &amp; Mohammed 2016). It is arguably best conceived as a kind of dialogue, even if one can also “argue” with oneself, in long speeches or in writing (in articles or books) for an intended but silent audience, or in groups rather than in dyads (Lewiński &amp; Aakhus 2014). But argumentation is a special kind of dialogue: indeed, most of the dialogues we engage in are not instances of argumentation, for example when asking someone if they know what time it is, or when someone shares details about their vacation. Argumentation only occurs when, upon making a claim, someone receives a request for further support for the claim in the form of reasons, or estimates herself that further justification is required (Jackson &amp; Jacobs 1980; Jackson, 2019). In such cases, dialogues of “giving and asking for reasons” ensue (Brandom, 1994; Bermejo Luque 2011). Since most of what we know we learn from others, argumentation seems to be an important mechanism to filter the information we receive, instead of accepting what others tell us uncritically (Sperber, Clément, et al. 2010).
