What’s Going On? Disinformation, Understanding, and Ignorance

Abstract Disinformation is a growing epistemic threat, yet its connection to understanding remains underexplored. In this paper, I argue that understanding – specifically, understanding how things work and why they work the way they do – can, all else being equal, shield individuals from disinformation campaigns. Conversely, a lack of such understanding makes one particularly vulnerable. Drawing on Simion’s (2023) characterization of disinformation as content that has a disposition to generate or increase ignorance, I propose that disinformation frequently exploits a preexisting lack of understanding. I consider an important objection – that since understanding is typically difficult to acquire, we might rely on deferring to experts. However, I argue that in epistemically polluted environments, where expertise is systematically mimicked, deference alone provides no reliable safeguard. I conclude by briefly reflecting on strategies for addressing these challenges, emphasizing both the need for promoting understanding and for cleaning up the epistemic environment.
