Re: Predictive Coding/FEP if a simulation or a thought construct is unfalsifiable, then the brain essentially ruminates on it trying to verify it by completing the (Markov) chain of thought. This causes entrenchment and leads to undue weight, thus allowing these unprovable concepts to often exceed the weight of other constructs with proper signaling.

If this is so, then please consider that the brain will begin “hyper-evaluation” (anxiety), reflecting upon many potential scenarios often times quite generally, in an attempt to resolve the perceived danger. This is likely compounded for those labelled as highly "creative" or "intelligent" (if we consider rate-of-simulation to be considered in the evaluation of either label.

If it's true that otherwise "smart" and/or highly creative people may come to believe seemingly unbelievable or even irrational things.

First post & have to say I can't get over the sublimity of our betwixt. I developed synesthesia recently and ever since have been really, really into theories—manifold, category, control, group—differential geometry, neuroscience(Friston & Penrose) and morphemic and sub-morphemic linguistics. I prefer to only discuss falsifiable claims. Much to say, just glad to be here!
