 Although Graff Fara defends an epistemic solution to the paradox, she proposes a dynamical contextualist explanation of the intuitive appeal of the conditional premise(s). On her view, vague predicates express properties that are interest-relative in the sense that their extensions are determined by what counts as significant for a speaker at a time. The premises of the paradox seem true because a speaker performing a forced march has a “standing interest in efficiency that causes [him] to avoid making discriminations that are too costly” (Fara 2008: 327-8). For example, for any pair of neighboring, incrementally different heights in a sorites series for ‘tall’: when the speaker is actively considering the pair, so that the similarity between the two heights is salient, the cost of discriminating between them outweighs the benefits:
