I don't have good thoughts about that. There may be something about sheep and goats, as a general rule but certainly not a universal law. It is possible that some are more cosmically interesting than others for some reason (perhaps a matter of their circumstances and not their character), but it seems unwise to ever think that about oneself; breaking the fourth wall is always a bold move, and the gods would seem to know their tropes. I wouldn't go that route too far without expectation of a Wrong Genre Savvy incident. Or, y'know, delusionally narcissistic schizophrenia. Ah, the power of the identity of indiscernibles. Anyhow, it is possible such evidence is not so rare, especially among sheep whose beliefs are easily explained away by other plausible causes.
