 One benefit claimed for this basic approach is that it provides an intuitive account of why knowledge is inconsistent with luck of a certain sort. For instance, some begin with the intuitive thought that you don’t know something if it is “largely a matter of luck” that you believe it (Riggs 2007). But why does knowledge preclude luck in this way? In the first detailed attempt to answer this question, Wayne Riggs says that the opposition between knowledge and luck is best explained by the hypothesis that knowledge is “an achievement for which the knower deserves credit” (Riggs 2009: 341). And knowers deserve credit because they believe the truth because of their virtue (Greco 2003). In response, some have argued that luck and virtue are orthogonal dimensions of epistemic evaluation (Pritchard 2012), and that knowledge must be due to virtue more than luck, as opposed to virtue rather than luck (Carter 2014).
