Elements in Epistemology Higher Order Evidence and Calibrationism

The higher-order evidence debate concerns how higher-order evidence affects the rationality of our first-order beliefs. This Element has two parts. The first part (Sections 1 and 2) provides a critical overview of the literature, aiming to explain why the higher-order evidence debate is interesting and important. The second part (Sections 3 to 6) defends calibrationism, the view that we should respond to higher-order evidence by aligning our credences to our reliability degree. The author first discusses the traditional version of calibrationism and explains its main difficulties, before proposing a new version of calibrationism called 'Evidence-Discounting Calibrationism.' The Element argues that this new version is independently plausible and that it can avoid the difficulties faced by the traditional version.
