@ETpro “When debaters dismiss solid epistemological statement by simply saying “You seem to be thinking in absolutes which do not exist in this reality.” then they either have conceded and don’t wish to admit it, or aren’t very expert in epistemology. :-)”
Actually, his response made perfect sense. He made the point that relying on expert authority gives a probabilistic conclusion. It is only fallacious if one claims that an authority is necessarily true—which is not what he claimed.
That experts are more likely to know what they’re talking about is completely uncontroversial, and that various people on here are trying to argue against what appears to a truism, serves only to reinforce @plexial‘s argument. (There are some very rare instances where going against expert consensus can be justified.)
@plexial‘s question did amuse me, because it really just seems to be a restating of the Dunning-Kruger effect, but framed in a rather accusatory manner, and with a hint of personal hubris. Instead of people lucidly interpreting the underlying sentiment, the responses have been to “take him down”, and to show that he himself is somehow lacking expertise, or to take the predictable sarcastic route of saying that they’re not expert enough to answer him—all which gained many mutually congratulatory GAs.
A Q&A site like Fluther is likely a self-selecting sample of people who like giving their opinions on all sorts of matters, and these will invariably include lots of bad, non-authoritative answers from people who really do overestimate their intellectual worth and competence.
Just to take the focus away from Fluther, I think there really is a problem with people wilfully refusing to recognise expert authority on all sorts of important matters. Yes, ideally one would not simply accept the views of experts just because they’re experts—we’d also be able to assess their arguments astutely and come to agree with a particular expert consensus mostly from our own intellectual endeavour and scrutiny. This is generally not practical or feasible even for the brightest and most diligent of us.
As for the unwashed masses, they are often incredulous in the face of expertise, and sometimes even contemptuous and hostile. I have seen instances of thoughtful, intelligent experts, diligent and vastly experienced with a wealth of knowledge at their disposal, dismissed as “just having an opinion”.
That’s just my opinion.
