Epistemic bias anti-lincenses NPIs in polar questions

There is general agreement that the distribution of any is unrestricted in polar questions. I argue that this is not the case: in contexts where there is epistemic bias in favor of the prejacent of a polar question, the question exhibits the same behavior as a declarative with respect to the licensing of any. I provide an account for this observation in terms of intervention: epistemic bias forces polar questions to be parsed as having a silent modal E which intervenes between any and the question operator whether that otherwise licenses any.
