 There are a couple of different ideas that epistemologists sympathetic to higher-order evidence typically aim to capture. One is the thought that higher-order evidence requires us to “bracket” or set aside some of our first-order evidence and reasoning. This is often called “Independence”. The second is the thought that, in accommodating one’s higher-order evidence, one should somehow adjust one’s first-order belief to match what one has learned from the higher-order evidence: either to match what one believes or has reason to believe would be rational, to match one’s expected level of reliability, or some variation on one of these. Principles dictating how one should calibrate one’s first-order beliefs in light of higher-order evidence are often called “level-bridging principles” or “calibration principles”.
