Far more frustrating and annoying is when people like that say things that are blatantly and provably wrong with complete certainty to an expert in the field and then actively refuse to hear any explanation or proof of the reality of the situation.

[detrites]

Far more annoying, is when an expert is so mired in their professions dogma they lead those trusting them astray. The label "expert" is itself a counter to the skepticism and humility required to reliably maintain a grasp on reality.

Unless that's being assessed by a "skeptic" who literally can't do the math required to fully understand the topic they're being skeptical about.

Tautologies are correct by definition, experts are not.

Based on my observations they seem to be usually perceived as correct by definition, but that [culturally trained and regularly reinforced] perception, and the methodology that produces it, is technically incorrect.

[empyrrhicist]

Not sure what tautology you're referring to, but nobody is claiming experts are infallible - that's silly.

I made my comment based on having seen lots of HN commenters confidently dismissing various widely accepted (read: current best) physical theories based on appeals to intuition and specious or incomplete reasoning.

This:

"Unless that's being assessed by a "skeptic" who literally can't do the math required to fully understand the topic they're being skeptical about."

The subset of skeptics who "literally can't do the math required to fully understand the topic they're being skeptical about" (or in other words: aren't smart enough to form a non-incorrect opinion) are necessarily ("by definition") going to be incorrect.

While this sort of rhetorical, heuristic-exploiting language can be persuasive (because it exploits heuristics), it is often misinformative.

This can be easy to notice by replacing "skeptic" with various other categorizations (such as based on race, gender, religion (but often only certain ones)) - if one is to do that, the accompanying logic typically changes, &/or the person will take object level offence at the content of the analogy, causing them to be unable to appreciate that the modification to the topic has caused the logic to change.

> but nobody is claiming experts are infallible - that's silly.

I agree, hence I made no such accusation.

I'm curious why you brought this up - were you under the impression that I had done that, or were you maybe framing the conversation to make it appear that I had done that (which could cause 3rd party readers to have a negative opinion on my other words)?

> I made my comment based on having seen lots of HN commenters confidently dismissing various widely accepted (read: current best) physical theories based on appeals to intuition and specious or incomplete reasoning.

Well sure: skeptics, being humans, are often incorrect. But similarly, I've also seen lots of HN commenters who identify as ~"scientific thinkers" confidently dismissing various widely accepted theories (and various other cognitive errors) based on appeals to intuition and specious or incomplete reasoning. Consequently, I am "not a fan" of these sorts of people - however, the degree to which* various subgroups of people are guilty of various crimes is a very easy thing to get an inaccurate read on, since perceptions seem to necessarily rely upon substantial heuristic thinking (which makes sense if you think about it).

This is getting a bit hair-splitty for me, but in case it helps, I think you're misunderstanding the thread, or at least interpreting it entirely differently than I am. Here's my take on where we are in case you find it helpful or interesting.

> The subset of skeptics who "literally can't do the math required to fully understand the topic they're being skeptical about" (or in other words: aren't smart enough to form a non-incorrect opinion) are necessarily ("by definition") going to be incorrect.

My post was intended to highlight my perception of the prevalence of a certain type of argument made in this context, and you're objecting to my description as if it was a logical argument. You are responding as if I am somehow logically comparing "experts" and "skeptics", as if one or the other category implies correctness. I didn't intend to make any such comparison, so I am left struggling a bit as to how to respond.

I intended to say, essentially: "In this context there are people working from incorrect assumptions and with insufficient knowledge, and it annoys me." You responded, essentially: "If people work from incorrect assumptions they are necessarily wrong, so that's a tautology." I don't believe that reasoning is either correct or helpful.

You are correct that I am using a number of heuristics, because that's how people generally communicate. In this case, I've seen a large number of discussions adjacent to the parent thread, and so I necessarily posses a heuristic to identify commonalities. The comment I replied to is not incorrect:

"Far more annoying, is when an expert is so mired in their professions dogma they lead those trusting them astray. The label "expert" is itself a counter to the skepticism and humility required to reliably maintain a grasp on reality."

That describes a real phenomenon, and I agree with the poster that it is annoying. I also see this sentiment overused and applied by people matching the heuristic I described, thus the comment. Ultimately, the discussion was a subjective comparison of the perceived relative prevalence of certain types of claims in online forums like this, and the attitudes of the posters about them.

To continue, you said:

> I agree, hence I made no such accusation. I'm curious why you brought this up - were you under the impression that I had done that, or were you maybe framing the conversation to make it appear that I had done that (which could cause 3rd party readers to have a negative opinion on my other words)

I'm certainly not trying to put words in your mouth, but I felt that you were trying to force me into a comparison I was not intending to make. The perception of experts as "correct by definition", to me, is orthogonal to the discussion which was going on. Sure, that happens and it's not correct. Nevertheless, working to develop reasonable heuristics about when to trust expertise is a rational thing to do.

> the degree to which* various subgroups of people are guilty of various crimes is a very easy thing to get an inaccurate read on, since perceptions seem to necessarily rely upon substantial heuristic thinking (which makes sense if you think about it).

I agree with that, and perhaps my attitude has also been unhelpful. To be clear, I don't have any sort of general opinion about how often "experts" and "skeptics" are correct, because those terms are vague and get used differently in different contexts, and because "being correct" is also pretty squishy if you drill down to any particular area. To make matters more confusing, I find that the most vocal anti-expertise skeptics are usually experts in something other than what they're skeptical about.

I'm not sure where that leaves this conversation, except that I think we differ somewhat in how useful we think heuristics are when reasoning under uncertainty and imperfect knowledge. This is also more abstract than I think is probably useful.
