People have been analyzing this psychology for years. It's basic dictator stuff. Stalin believed firmly in the notion that uniting the people under your ideology means inve ting facts to u ite them under. It's part of why they had the famine and how it got worse, because Stalin elevated scientists who made up things to support the state and executed anyone who said things Stalin didn't want to hear.
When you have a movement that intentionally isolates itself from information because information is supposedly only offered by the devil, you wind up with a bunch of rubes who will do or believe anything for you.
Beyond that, a lot of the "pipeline" stuff is supported by Russian cyber agents who take advantage of social media's irresponsible hate-click economy to drive hate and weaken western politics. Before the internet they used to promote this kind of rhetoric in their satellites so they could exert their influence easily due to nobody in the nation knowing what's fucking true.
