The vast majority are complete airheads that essentially go through life on autopilot. They've never head an original thought. All conflict in their life in either superficial interpersonal nonsense, or performatively questioning why people don't think the same things they do using the lines they've seen and heard from the various hosts of current year. They potentially could think for themselves but have never gotten anywhere close to having or wanting a reason to. The easiest way to snap people out of it is to show how completely uninformed and often seemingly intentionally incorrect msm is regarding some topic the person is actually knowledgeable in, but this obviously requires that the person isn't a pure npc with only generic liberal arts knowledge.
