Yes, that's it exactly! "There's a 'poster brand equity' built up
which you can challenge or not, depending on how your BS detector
is working on a particular issue", if I may paraphrase.

But your apt description applies to all, not just to those who you
think of as "authorities".

Here's where we still differ: I do not "attribute levels of authority"
as a step in my thinking. (Your idea of asking a trusted third party---
whose advice you evidently hold in esteem---about a post is of course a
good idea.) Rather, I investigate the qualifications of the speaker only
after---if at all---hearing what he or she has to say. I myself don't
have time to investigate the credentials of each evidently knowledgeable
poster, unless, as you put it, my bullshit detector goes off. Keeping
one's Bogosity Meter well-tuned is indeed the ticket.

But more importantly, I think that you still have here in mind
the cases where the poster is attempting to be merely informative,
and is not putting forth his own slants, interpretations, conjectures,
arguments, or refutations. I described these latter before: they slide
into controversial areas, often tinged with political or philosophical
ideology, and are usually more "self contained" (than, say, someone's
description of medical symptoms or physics). In these controversial
cases, Eliezer's dictum, "trust content, not speakers" fully applies.

In these cases where refutations and controversy, or conjectures
and refutation are present, it is inappropriate to refer to one's
own or anyone else's qualifications to speak, as it becomes
tantamount to arguing from authority. It even has the baleful
effect of inhibiting contributions, as the recent joiner implied
who spoke of his own hesitancy.

Yes. Perhaps we entirely agree; after all, were I suffering from MS
and read that post, doubtless I'd examine the credentials of the
person dispensing medical advice before *or* after reading it.

Yes, and we must avoid the temptation to think that it will ever
be different: it's not really possible for any three people to
see something in *exactly* the same way.
