Has there been discussion of Jack Good's principle of nondogmatism? (see Good Thinking, page 30).
The principle, stated simply in my bastardized version, is to believe no thing with probability 1. It seems to underlie Good's type 2 rationality (to maximize expected utility, within reason).
This is (almost) in accord with Lindley's concept of Cromwell's rule (see Lindley's Understanding Uncertainty or https://en.wikipedia.org/wiki/Cromwell%27s_rule). And seems to be closely related to Jaynes' mind projection fallacy.
There have been discussions on this topic, although perhaps not framed as nondogmatism. If you have not read 0 and 1 are not probabilities and infinite certainty, you might find them and related articles interesting.
