I have both forms. The inner monologue voice is a common learned way of thinking. For me it’s a way of testing how things sound, before using it in public. It also formalises ideas for memory.
Below that, I have my mindstream. It’s the active amalgamation of ideas, images and concepts that forms my intellect. It’s difficult to map to language, since it’s not bound by language.
The inner monologue is useful, but not required for intellectual thought. In fact, it can be a detriment. It’s hard to process things, when you don’t have the language for it. It is, however quite useful for presenting ideas. An inner monologue lets you practice what you will say, and how you will explain things to someone else. I’m autistic, so I often need to preprocess what I am about to say. My inner monologue lets me test if it’s “socially inappropriate” (aka batshit insane) before it comes out my mouth.
Conspiracies need to be small and self contained. The more people involved, and the longer it needs to hold, the less likely it is.
E.g. 9-11 being a government conspiracy with 1000s involved in the cover up? Likely false. George Bush getting info about an imminent attack, then having the info buried, since it would be useful? Far more plausible.
In this case, the elite standing in lockstep to cover their own arses is quite plausible. It also fits that the group is already too large to keep the conspiracy contained, and so information is leaking like a sieve.
