Specific to what you're talking about there is a bifurcation (really a series of them) when the system detects the invalid data and re-calibrates. Often this takes the form of a "conversion experience", and some people build specific rituals (initiations) to try to engineer them artificially.
He once described society as "open warfare between competing gangs of magicians" or something like that. By "magicians" he meant people who deliberately program the "reality tunnels" (his jargon) of others.
What you're talking about, in the context of RAW's models, is a kind of transcendent goal: allegiance to truth itself. (And critical thinking, evidence-based data collection, etc. All that good stuff.) You're part of the great anti-conspiracy.

Now that I think about it I seem to recall that RAW had a piece where he talks about experienceing the Santa Claus disillusionment. I think George Carlin does in his autobiography.
This conditioning spreads, children are literally meme machines. Bit by bit faulty pieces of information get lodged in gullible little brains. By the time you reach the age where critical thinking skills become important the whole world around you has become infested with lies and half truths, and the bits stored in your head are full of logic holes and trash.
So then, at the ripe old age of 25, a person with no scientific background receives from a number of directions at once something that is not supported by facts. By default, they are going to do what they've always done: accept it as though it is true. And they will spread it around, a click here, a retweet there, a like over here. Then, once they are invested in it, just like with Santa Clause there are always going to be some individuals that refuse to give up the lie. They persist in believing it because that's easier than to give it up.
It's how cults are formed and how people end up with false beliefs that cause them to do really bad things. Like kill others. The 5G Virus Conspiracy is falling into very fertile soil. Against a backdrop of low level continuous distrust of the authorities, the vast gap between poor and rich and the number of absolutely outrageous things that we have told people to accept as fact this is not all that surprising.
If we want to change this we will have to start by ensuring that what we tell people from a very early age is the truth, and that lying and spreading a falsehood as such would be - again - seen as something dishonorable.
This of course is entirely not acceptable to large fractions of society. So we will have to live with the fact that some people become so gullible that they will believe anything that they are being told by some guy in a frock, a labcoat or who they happen to resonate with. Critical thinking skills are like other skills: you have to learn, and then you have to practice them the rest of your life to make sure you retain them.
Until then you will see these conspiracy efforts have great success and this should not surprise us at all.
