I do think there would be some utility to isolating and elevating this particular issue. It seems to be pretty uniform as a phenomenon. Conspiracy theorists can't remember the past.

I also think there's a kind of fascinating meta question about how the nature of conspiracy theorizing itself response to challenges. I think fact checking is a perfectly legitimate institutional response to it and in a healthy culture it would be appreciated and valued and utilized and would play a role. But the conspiracy ecosystem writ large has had to think of a systematic response to the phenomenon of fact checking and like evolve its way out of vulnerability to it.

One is to dismiss correction for any number of reasons, another is to kind of cultivate a mindset and attitude of frenzied emotional subject shifting that kind of exists and sustains itself in a way that's detached from the habit of factual investigation. But I also think there are such things as like experimenting with principled philosophical stances like relativism or disputing baseline concepts like burden of proof or especially fascinating in the flat Earth corner of the internet are philosophical positions about the relativity of knowledge and extreme subjective and skeptical orientations towards the world and the possibility of data and knowledge.

So even though I actually personally believe in the importance and significance of isolating out and emphasizing specific clear and short criticisms such as conspiracy theorists can't remember the past. I do think they have processes to metabolize and respond to those criticisms and I'm fascinated to learn to what extent they might try to articulate a principle in defense of not remembering the past. Because surely some will give it the college try.
