Argumentation is important for sharing knowledge and infor-mation. Given that the receiver of an argument purportedly engages first and foremost with its content, one might expect trust to play a negligible epistemic role, as opposed to its crucial role in testimony. I argue on the con-trary that trust plays a fundamental role in argumentative engagement. I pre-sent a realistic social epistemological account of argumentation inspired by social exchange theory. Here, argu-mentation is a form of epistemic ex-change. I illustrate my argument with two real-life examples: vaccination hesitancy, and the undermining of the credibility of traditional sources of in-formation by authoritarian politicians.

信任在争论中的作用

争论对于分享知识和信息很重要。鉴于据称一个论点的接受者首先要参与其内容，人们可能会期望信任扮演一个可以忽略不计的认知角色，而不是它在证词中的关键角色。相反，我认为信任在辩论参与中起着根本性的作用。我提出了一个受社会交换理论启发的关于论证的现实社会认识论解释。在这里，论证是一种认识交换的形式。我用两个现实生活中的例子来说明我的论点：疫苗接种的犹豫，以及威权政客对传统信息来源可信度的破坏。
