We should be careful not to fall into action bias. E.g. the thought that we need to do something, anything, since that can lead to counterproductive solutions.
I've begun to look at information problems like this not too differently than viruses of thought. Right now these viruses are running rampant because we've never had to deal with anything like them before on such a wide scale. It seems perfectly possible to me that over time we will develop social standards that immunize us from these viruses. More and more people will begin to disregard clickbait, outrage-inducing headlines, etc. They will simply become less salient the more and more we experience them.
Reframing the question at hand around this metaphor: What would an effective vaccine look like for these thought viruses? I'm not at all sure, but I can't imagine any kind of partisan response that would work, since these viruses infect left and right alike, and many people will bend over backwards to argue otherwise. Until we can face that fact honestly, I don't see how we could even begin to have a productive conversation about a solution.
