It is often thought that the phenomenon of rational inquiry for the sake of confirmation poses a challenge for Friedman’s “Don’t Believe and Inquire” norm (DBI). It is also often thought that, insofar as that phenomenon really does pose this challenge, it also challenges the claim that inquiry is essentially question-directed and driven by interrogative attitudes. This paper develops a new argument against DBI grounded in the phenomenon of confirmation-driven inquiry. This argument can presuppose that interrogative attitudes are essential to inquiry.

Recent epistemological literature features compelling and novel arguments for thinking that an agent can rationally believe each member of a set of propositions while knowing that one of the members is false. Perhaps more provocatively, these proponents of "Rational Inconsistency," as it were, claim that it’s also possible to know each true member of the set while knowing that one of the members is false. Call this "Knowledgeable Inconsistency." In this article, I explain why, if Knowledgeable Inconsistency is true, then, on pain of an absurd implication about how confirmation works, we should reject non-skeptical Infallibilism about knowledge. For that same reason, the recent proponents of Rational Inconsistency should also reject non-skeptical Infallibilism.

In this paper, I argue that the following claims are jointly inconsistent: (1) that an agent’s justification for belief, if it’s constituted by evidence, depends on the profile of her background beliefs, (2) that whether or not a group believes a proposition is solely dependent on whether the proposition is jointly accepted by its members, and (3) that prototypical group beliefs are justified. I also raise objections to attempts to resolve the tension by retaining (2) and (3). The upshot is a novel objection to the Joint Acceptance Account of group belief since it seems to be accompanied by a kind of skepticism.
