[Avodah] Heseibah, Halachah and Science

[Sholom Simon]

His teshuva seems to fit a meta-halachic theory I've heard from a teacher
that many times Chazal knew the mesorah/law/torah she'bal'peh, but didn't
necessarily know the reason and they (to put it bluntly) guessed at the
reason.  I've heard the kashrus status of bee honey described in that way
-- i.e., nobody disputed that bee honey was kosher, but they were incorrect
when they ascribed a scientific reason for it.

How might that apply to other situations?  (Killing lice on shabbos?).  It
is a general meta-halachic rule?  If not, when is it applied and when not?
Or is this a post-hoc justification?  I have no idea...

Another teshuvah by R' Asher Weiss. I'm sharing it for the metahalakhah
> implications. Must heseibah be on the left even now that we know there
