Abstract: Argumentation is often contrasted with testimony in that in cases of testimony, an epistemic agent (presumably) primarily evaluates the trustworthiness of the source of information (the informant), whereas in argumentation there is (presumably) primarily engagement with the content communicated. I have argued however (Dutilh Novaes 2020) that trust and trustworthiness in fact play an important role in argumentation too. From this analysis emerged a three-tiered model of epistemic exchange, inspired by the framework of social exchange theory (an influential framework in sociology and social psychology). According to this model, there are three stages for an instance of epistemic exchange to take place: 1- a relation of attention is established between the parties; 2- a relation of sufficient trust is established between the parties; 3- the parties can finally engage in fruitful epistemic exchange. This model generalizes beyond argumentation, and sheds new light on a number of phenomena that have attracted the interest of social epistemologists such as epistemic bubbles and epistemic injustice, among others. In this talk, I present the model in detail and discuss some of its applications.
