Misinformation and Epistemic Harm

Abstract

Standard accounts of misinformation require that it is either false or misleading, in the sense that it leads people to false beliefs. But many examples of misinformation involve true information that leads people to true beliefs. So, I propose a new theory of misinformation: misinformation is information that is epistemically harmful in the sense that it is disposed to reduce the overall quality of a subject’s epistemic position. This includes not only causing the subject to form a false belief, but also causing the subject to form beliefs that are otherwise epistemically deficient or to abandon or reduce confidence in epistemically good beliefs.This account improves on standard accounts in two ways. First, it more closely matches intuitive judgments about what counts as misinformation, including cases of failed deception and information that is spread without regard for its truth. Second, it provides a natural account of what is wrong with spreading misinformation: it contributes to an epistemically hostile environment in which we are more likely to become epistemically worse off when we gather more information.
