Does Lexical Coordination Affect Epistemic and Practical Trust? The Role of Conceptual Pacts

Abstract

AbstractThe present study investigated whether humans are more likely to trust people who are coordinated with them. We examined a well‐known type of linguistic coordination, lexical entrainment, typically involving the elaboration of “conceptual pacts,” or partner‐specific agreements on how to conceptualize objects. In two experiments, we manipulated lexical entrainment in a referential communication task and measured the effect of this manipulation on epistemic and practical trust. Our results showed that participants were more likely to trust a coordinated partner than an uncoordinated one, but only when the latter broke previously established conceptual pacts.
