 Finally, the way that some theories model presuppositions can give rise to new types of related inferences. For example, Chemla (2008) notes that the sentence in (54a) strongly suggests that the speaker does not have a sister. According to Heim (1991), this inference arises from the fact that the speaker did not utter the alternative in (54b), which strongly presupposes that the speaker does have a sister. This prediction follows from Heim’s Maximize Presupposition! principle, that a speaker will use the felicitous sentence with the strongest presupposition among a set of alternatives. These types of inferences have been referred to in the literature as ’anti-presuppositions,’ a term originating with Percus (2006).
