 Metaepistemological realists at the very least accept that there are epistemic facts, and that these facts are not (non-trivially) mind-dependent. Thus, this means that, for the realist, when you say that you know that Paris is the capital of France, there is a fact of the matter—either you do or you do not know this—and further, the obtaining of this fact is not simply down to, e.g., cultural consensus, approval, or what you think about what you know. Thus, for the realist, when two people disagree about who knows what, this disagreement is genuine; both parties cannot be right (cf., Kölbel 2004; MacFarlane 2011); likewise, for the realist, there will be cases where you believe you know something, and you are mistaken.
