Been burned by that a few times by blindly trusting some statements from some respected people only for it to blow up in production because they were wrong :).

Yes, now generalize the theorem to any human to make it usable on a daily basis.
That is, strangely, until those humans turn to a topic I know something about. Then their reliability drops like a hot potato. At least they get everything else right!
