I am genuinely surprised at the comments in this thread. This article starts "That said, I do not think there is much evidence that misinformation has become more widespread, that this increase in misinformation is due to technological change, or that it is at the root of the political trends liberals are most angry about", which is immediately making this a partisan issue.
Secondly: "The internet makes me better informed". This is his perspective. Many people are not actively looking for information outside of their own biases. Thirdly: "Cranks often know a lot"... Should be titled "Cranks often think they know a lot". Just because someone can state a fact does not mean they are sufficiently educated to analyze that fact. Saying that there are "vaccine side-effects" (stated in the article) does not mean that Joe Rogan is able to weight the information in totality with other information from the studies. After this, the article got into a bunch of "whataboutism" and doesn't really compel me to believe that misinformation is not a problem. I agree with polarization getting worse, but could that be a symptom/signal of misinformation, is there a cause/effect relationship?
My thoughts:
There are multiple categories of false information spreading on the internet right now. I honestly believe that there is manipulation of the public happening on all sides of this problem, the thing that is still unclear is whether there is a coordinated source of this manipulation or if it is organic.
I disagree pretty strongly with the "misinformation problem" being misinformation. Anecdotally (yes, I know it's not scientific but it is the same information the author is giving) the amount of things shared on social media that are demonstrably wrong has increased over the past couple of years. There are people who truly believe that Trump was going to rally the military on January 20th or whatever date to "take back the white house". This got shared to numerous social media sites and was reposted that the "true president" was coming back. This is one explicit example, but similar things have been popping up for the past couple of years and spreading like wildfire. 5G vaccines, QAnon, flat earth, and many other fringe movements exist and ARE misinformation, the questions is how broad these movements are.
If you claim that misinformation is just "information that is partisan" or "wrongthink" I would urge you to dig further into some real, damaging examples. I think there are times when the term is weaponized, but there is a serious increase in how easy it is to spread words in this day and age. The internet, social media upvotes and shares, and other technological tooling has made the problem worse by letting people feel validated by opinions and "likeableness" of something versus things based in facts.
Real people are dying because of perpetuated information on social media and "news" outlets. Yes I understand that "individualism" should let them decide whether to make that choice, but there is a public health issue here when people are basing that choice off of Facebook memes and shared content that has no basis and gets 100k shares because it sounds cool.
