 There are no doubt many other sorts of constraints which a modal fictionalist may appeal to in order to narrow down the class of fictions about possible worlds which are acceptable for her purposes. Even after all of these constraints are in place, however, there may still be the theoretical possibility that more than one fiction about possible worlds (complete or incomplete) satisfies them equally well. A fictionalist facing a choice between equally deserving fictions would need to address the issue of what attitude to take to other modal fictionalists who choose differently. (Should they be judged incorrect? Correct, because judgements about the content of the modal fiction are relative to which (acceptable) fiction is adopted? Or should they be judged to be talking about something else?). Or perhaps the fictionalist could find some way to avoid making the choice of one single fiction. Woodward 2011 explores one way to avoid making this choice: he suggests modifying the fictionalist biconditional to relate modal claims to a range of acceptable fictions, allowing for some truth-value gaps when the acceptable fictions diverge from each other.
