There are plenty of authoritative reference books full of errors. Teachers in every subject can be wrong, convincingly.
I look for citations and footnotes. In many cases, accuracy isn't something that I worry about, as bad info becomes apparent, almost immediately. In cases where it matters, though, I may try a couple of verifications.
One problem with humans, is that we can be quite insecure, and will fight to the death to defend a provably wrong position, because we can't bear to be seen as in error.
Can you elaborate on this? I suspect that you’re thinking mostly of cases in which you already have a fair bit of domain expertise. But in the general case, this seems to be very untrue. Which is why it’s so pernicious that LLMs can generate such quantities of syntactically-plausible-but-factually-untrue text.
Can’t really put it into precise terminology, but I get a “gut feeling,” that something is/is not plausible, and it happens pretty quickly; usually when I start some implementation. I tend to learn by do[0] (note the “sample playground,” in each essay), so the “reality filter” gets applied fairly rapidly.
In any case, I have been dealing with misinformation (sometimes, deliberate), for a long time, and I’m still working fairly effectively, so I guess it works.
Can’t argue with results.
But (not speaking about your use specifically here) many people (most, I'd wager) use LLMs for many things beyond their own expertise. And it's there that they're most likely to be ensnared without even knowing it.
I definitely agree with your notion that learning-by-doing is a helpful salve for LLM falsehoods. It's no panacea (working != correct (an incorrect solution can appear correct over a given interval)), but it's a good way of working in general that helps keep LLMs in check. And it's very natural to code or other things that can be immediately applied.
But learning-by-doing of course doesn't work with topics that aren't immediately applied. Which includes lots of topics that people use LLMs for (Wikipedia too, for that matter).
The set of unfamiliar-or-unapplied is practically a lot larger than the set of familiar-or-applied.
I don't think it would be a good idea for me to suddenly decide that I want to get rich, selling antivenin.
On the contrary, I believe most people use them precisely to find out more about topics of which they know vanishingly little, much as they'd have used Google before LLMs.
