It must be consistent with itself, and with the things we know about reality.I disagree that a claim must be consistent with what we know about reality.
First, this statement is ambiguous, particularly "we" and "know."
Second, as I understand those terms, this criterion is not generally applied to claims. For example, we knew that time proceeded at a constant rate everywhere. By your criteria, we wouldn't have bothered listening to Einstein, because we knew that his claim was not consistent with reality.
