  This suggests that the notion of evidence in play in statements such as ‘evidence tends to justify belief’ and ‘rational thinkers respect their evidence’ cannot simply be identified with evidence in the sense of reliable indicator.  Let's call evidence in the former sense normative evidence, and evidence in the latter sense indicator evidence.  Although the normative notion of evidence cannot simply be identified with the indicator notion, we would expect the two to be closely linked, inasmuch as one's possession of normative evidence frequently depends upon one's awareness that one thing is indicator evidence of something else.
