The Internet is a double-edged sword. The good news is we now have true freedom of the press, where anyone can disseminate news without fear of censorship. The bad news is we now have true freedom of the "press", where anyone can disseminate "news" without fear of censorship. Unfortunately, too many people cannot or will not recognize the difference between news and "news". There is a reason legitimate news source value journalistic ethics and competent editors.
I'm not sure how comfortable I am with this suggestion, but in the light of "something really does need to happen," I'd make a suggestion:
--An entity that advertises itself as a news source, that puts up "articles" that they choose to pass off as journalism, real or not, needs some sort of "licensing" that may or may not be attributed to something like peer review that (while certainly not always perfect), works pretty well in governing science publications.
--Any online "news agency" would need to meet certain standards from a 3rd party, bi-partisan board of reviewers (this would probably be huge, international, and quite possibly burdensome) that establishes guidelines that govern standards and practices for online publications. Organizations that meet and pass these standards carry a seal on their main page, advertising them as a legitimate journalistic site (you know, something like a DOCG that legitimizes a Chianti which meets the exacting standards of the Tuscany region). Heh, maybe even those that do not meet this standard receive a warning label on their website: "Warning, the content contained on these pages can not be guaranteed as true or not. Consume at your own risk. Assume that you are digesting lies." Or you know, something less abrasive...
Now, I tend to find a suggestion like that distasteful because it rejects the spirit and primary MO of the internet, but we can't continue to ignore the inherent risk in the internet model. It's high time we just accept that old standards in news organizations--personal accountability and individual orgs guided by their own ethical standards--is simply outdated and was never designed for the world we currently live in.
We still have great organizations out there, even if many of them aren't perfect, you can still pretty much trust that you aren't being explicitly lied to every time a mouth is open or text is plopped onto a webpage. But there is just far too much chaff, and it is obvious and clear that large numbers of people are either unwilling to do the work to sift through this or, much worse--simply do not care (a few decades of conditioning to accept confirmation bias as honest reporting)
And this is a bi-partisan issue and a bi-partisan problem. Yes, liberals do have their own sort of bubble and if that wasn't obvious after the results of this election, then I'm not sure how else to make that more explicit. I think a lot of this has to do with ignoring the "Revolutionary" wave of Obama's first campaign--against what became the new liberal elite--becoming complacent with this as he became more and more of an establishmentarian--and falling back into the trap of accepting that high-minded, pseudo-academic-but-really-corporatist solutioneering that the Clintons really brought to the table. Dems ignored the similar wave of populism from the classic liberal base was thoroughly behind Bernie, pretty much as they were behind Obama, and then further ignored how Trump caught a lot of that same sentiment (Revolution--end of elitism), whether or not the sides were simply different. ...OK, that is a bit off topic of the beginning of my post, but while I don't want to fall into the "both sides do it" FE, it should be clear enough to anyone that politics and social division in this country isn't going to be getting any better until citizens return to a place where they can actually admit that they trust their information streams--and of course by that I mean legitimate information streams.
You can scream all you want about ignorance and blaming the ignorant for distrusting legitimate news and opting for fake nonsense, but that isn't going to change their attitude. It will remain the exact same problem after you are done screaming at such people. What, then, is the actual solution for bringing the intractable back into the world of honest discourse?
