 Some epistemologists argue that our first-order beliefs should line up somehow with our beliefs about rationality. (See Smithies 2019 and Titelbaum 2015, 2019, for example.) Others argue that our first-order beliefs should line up somehow with our beliefs about reliability. And still others incorporate elements of both. Some literature discusses both notions together and other literature distinguishes explicitly between the two. (See Christensen 2016b, Sliwa &amp; Horowitz 2015, and Schoenfield 2015a for a few examples of more explicit discussions. See also Dorst [forthcoming] for a comprehensive overview of some of the principles proposed in the literature and the relationship between them, and the entry on  epistemic self-doubt  for discussion of some other level-bridging principles in greater detail.)
