Fully agree. I've been thinking this a lot lately, and I've believe this is partly a reason why it's personally harder to slip into nihilism or some kind of nonsense, if you're grounded in reality one way or another. Though not always very convenient, genuine and constructive red teaming is invaluable even in one's thinking and worldview let alone everything else. And without philosophy we'd be just chimps who somehow figured out how to make nuclear weapons.
@SGE Right? It's a clear pattern with disinfo to silo people into small cultish bubbles - for example, "Everybody else is lying, except for flat earthers all around the globe!"
Get people attached to a siloed message instead of open reality, and they become incredibly manipulable, and incapable of maintaining a just democracy.
