It's complicated by the fact that the world has a history of vilifying new ideas -- that are later validated and become part of accepted science -- and dismissing their authors as crack pots. My standard go-to example of this is Semmelweis, though he's hardly the only one.

Despite various publications of results where hand washing reduced mortality to below 1%, Semmelweis's observations conflicted with the established scientific and medical opinions of the time and his ideas were rejected by the medical community. He could offer no acceptable scientific explanation for his findings, and some doctors were offended at the suggestion that they should wash their hands and mocked him for it. In 1865, the increasingly outspoken Semmelweis supposedly suffered a nervous breakdown and was committed to an asylum by his colleagues. He died 14 days later after being beaten by the guards, from a gangrenous wound on his right hand which might have been caused by the beating. Semmelweis's practice earned widespread acceptance only years after his death, when Louis Pasteur confirmed the germ theory, and Joseph Lister, acting on the French microbiologist's research, practised and operated using hygienic methods, with great success.

Galileo would be a more famous example of this phenomenon.

HN comments are locked to further replies after 2 weeks. That doesn't exactly help.

Sometimes, figuring out what considered discourse looks like in a certain area is an unbounded process.

Sometimes it hinges on drive-by enlightenment by someone who happens to have exactly the right resource and a willingness to necropost it.

Yeah, I appreciate HN not having a notification system for replies unlike Reddit, but even so there's some pressure to reply quickly more than deeply. I'd be very interested in seeing a discussion forum that's intentionally much slower, e.g., having replies only show up at the next hour or half-hour.

One thing you'd want to be careful about is letting people say "This is obviously wrong" and having something to that effect show up quickly, so you don't waste a bunch of people's time replying with the same thing.

It is on heck of a problem. We need two things to solve it. We desperately need networks of trusted institutions or experts to which we can offload some of the fact checking and individually we need to become much more skeptical about the information we consume. In fact we should be teaching our kids that most of the information they are likely to come across, outside a few trusted sources, is false, and often malicious.

it certainly feels as if people have become markedly stupider due to this phenomenon and the internet. has anyone attempted to quantify this? some measure of falsely held beliefs over time? level of conspiratorial thinking over time?

I don't think people are stupider in the sense of less knowledge (or less g, for sure), but there is a phenomenon where people are expected to know more and know it quickly. Before the internet, if you were a working scientist and you wanted to know about something that wasn't in your field, it was a fairly involved process to figure it out, not 10 seconds reading Wikipedia. Analogously, if you weren't a scientist at all, you'd have to ask a scientist, you couldn't spend 10 seconds reading and potentially misreading Wikipedia, you'd just say "I don't know."

I think this has consequences in other fields besides science too. The general public now has the ability to have well-formed opinions about government policy and its effects, for instance. That may in practice be making people more confident in their ill-formed opinions, where they would have previously deferred to experts. (Of course, it also is a great potential benefit if we use it right, because those experts will generally have their own biases and agendas.)

It ‘seems’ that way for sure, but i have a feeling its because these people who were always this way now have a platform to speak on, or that validates their existing thinking and solidifies it. Its a good point though - how do we test a theory on this? It would be interesting to see if people are doing scientific tests in this space
