Does this apply to you and any of your theories?
"The madman's explanation of a thing is always complete, and often in a purely rational sense satisfactory. Or, so to speak, the insane explanation, if not conclusive, is at least unanswerable; this may be observed in the two or three commonest types of madness. If a man says (for instance) that men have a conspiracy against him, you cannot dispute it except by saying that all the men deny that they are conspirators; which is exactly what conspirators would do. His explanation covers the facts as much as yours. Or if a man says he is the rightful king of England, it is no complete answer to say that the existing authorities call him mad; for if he were the king of England that might be the wisest thing for the existing authorities to do."

Nevertheless he is wrong. But if we attempt to trace his error in exact terms, we shall not find it quite so easy as we had supposed. Perhaps the nearest we can get to expressing it is to say this; that his mind moves in a perfect but narrow circle….in the same way the insane explanation is quite as complete as the sane one, but is not so large.”
-GK Chesterton (Orthodoxy)
TLDR – Stupid conspiracy theories can have perfect internal logic, but fall apart when presented with outside facts.
There is a larger context into which this fits, one which involves the true nature of human consciousness. Most people--I would estimate around 80%--are NPCs. Their thought processes are fundamentally different than what is assumed.
Starting with an understanding of that thought process, we can derive what Chesterton points out. NPCs do exist in a state of what could crudely be called madness, and less crudely described as psychosis. The fundamental nature of psychosis is a detachment from reality.
You can see demonstrations of this daily. NPCs will create "facts: quite freely, and bat away other facts as if they were annoying flies. What this points towards is that NPCs are not interested in exercising their rational faculties to ascertain objective reality.
Rather, their subconscious seeks psychological stability and comfort, and freedom from anxiety and stress. When they are presented with situations that tend to disturb these states, their subconscious rejects them. At the far end of the process is rationalization and, as Chesterton terms it, "insane explanations".
