Naive, wishful thinking is a real killer, but in most cases not in a totally rigged, temporary system like we have had these decades...
The next problem is that most have very little experience in building up, assessing and utilizing mental models, especially in concert when they might be mutually exclusive.
While even some of the wildest theories out might be good tautologies that explain everything within their purview very well they might still not fit in well with others, and will certainly lack the flexibility to merge into an even larger picture that explains even more.
Mental universes like this particular one of course can't even withstand the simplest probing and scrutiny, and they end up ballooning with even more fanciful explanations of any aspect that does not make sense at all when viewed from the outside.
Flat earth is really the prime example, but very easy to disprove of course. Hell, I've seen the bloody curvature crossing an ocean solo myself! That does not stop them, of course... ;-)
When it comes to the whole Q thing and basically anything in politics and especially hidden actions it all becomes way harder to handle because it is not about simple physics and logics, normally it belongs in the domain of human behaviour and psychology, which of course is far more complex and prone to exceptions, uncharted territory and outdated models because of tech.
What I do find fascinating is that so many relatively wild theories match and overlap very well these days, and often they are driven by people who seemingly has a lot to lose and not much to gain by sharing what the know or have experienced!
