Honestly? These kinds of stories should enforce the general idea. Trust has to be seen as a long term game, though. And requires well run checks to keep things trustworthy.

So, if you view trust as only a short term, "the answer is always right," then that will fail. But you should not have a sole source here.

And this style of system is no different from authority anywhere else. You should be able to trust your local religious/community leader. But you should also not have one that is absolute authority on their own authority.
