Anecdotal Evidence

[Mister Agenda]

Ok... can you define the specific circumstances, and justify the reasoning behind the difference?

I'd say at the point where different religions provide contradictory anecdotes, it's over as far as anecdotes go. If two witnesses not in cahoots report the same thing, it may suggest there's something to try to find. If they contradict each other, you've got no particular reason to think either is right, unless there is other information to support one over the other (e.g., one says they saw a reflection, the other says they saw a ghost; well, we at least know reflections are real).
