Perhaps we could tackle this "problem" from a different direction. Head them off at the pass so to speak, by limiting the possibility of erroneous replies.

Add a new button to the consideration nodelet that is only presented to those monks that have never posted an incorrect answer.

All new nodes would be locked, and no one would be able to post a reply until that select band of Uber-monks have "signed the post off", by clicking the above button, indicating that they either do not know the answer, or cannot be bothered to post one.

Only once all Uber-monks have so signed a post off, would that post become unlocked. and so become open to the rest of us mere mortals to post our thoughts, half-remembered plagerisms and wild-arsed guesses.

I was half way into coming up with an elaborate scheme for determining who should be afforded the privaledge of Uber-monk; by analysing their XP/posts ratios, probably limited to first child replies or similar; a cross-authorisation scheme; and a few other frills; when it struck me.

Most of them seem to already know who they are, so maybe we should just let them "sign up" for Uber-monk status via a button on their preferences?
