Disagreement, Credences, and Outright Belief

Abstract

This paper addresses a largely neglected question in ongoing debates over disagreement: what is the relation, if any, between disagreements involving credences (call them credal disagreements) and disagreements involving outright beliefs (call them full disagreements)? The first part of the paper offers some desiderata for an adequate account of credal and full disagreement. The second part of the paper argues that both phenomena can be subsumed under a schematic definition which goes as follows: A and B disagree if and only if the accuracy conditions of A's doxastic attitude are such that, if they were fulfilled, this would ipso facto make B's doxastic attitude inaccurate, or vice‐versa.
