 The prima facie element of the account means that the typical properties on the speaker and hearer side are only default properties associated with surface features of the utterance: the declarative sentence type, a typical intonation pattern, etc. There are many possible reasons why a speaker may utter such a sentence without believing the proposition, and why a hearer may not adjust their credence in the typical manner. For example, the speaker may be lying, the hearer may distrust the speaker, or may already have given the proposition a very high credence before the utterance. On Pagin’s picture, it is the cognitive patterns associated with surface features, on the production and comprehension sides, that characterize assertion. This way of dividing the account between speaker and hearer is somewhat controversial.
