Which means you must beat them over the head with knowledge and then discourage the information gathering phase in order to keep being the anointed one

You could also just overload them with information until they just cannot keep up with the constantly flowing happenings and then rewriting of those happenings.

Which seems to be how this is going. People don't have the time or energy to keep up in all the battlefields going on in this culture war, so they outsource the flow to who they consider "trustable" sources. And because the human mind loves consensus, "trustable" usually ends up as "says what I want to hear." Which then creates an echo chamber for yourself where you discount all information that doesn't fit as lies or psyops and overload yourself with confirmation bias. And then it just spirals from there until they feel strongly enough to be shouting down other people who try to dissent.

A new query becomes how do you end this war state of the mind?

I don't think we can truly. Humans will always create problems to overcome, its just in our nature. The best solution we have is to fractalize into tinier communities, where you have face to face interaction with all parties and the world is a lot smaller, thereby giving you full access to all information directly.

This isn't possible more than likely, and is probably communism in a way, so the best we can hope for is to mitigate the negative effects the best we can. What the best way to do that is, is hard to say.

I won't pretend to have all the answers, I'm just an aging coonass, but I at least try to avoid some of the common pitfalls to keep myself from falling into the same mindsets.
