There’s an important difference between brain damage and brain mis-development that you’re neglecting. The various parts of the brain learn what to expect from each other, and to trust each other, as it develops. Certain parts of the brain get to bypass critical thinking, but that’s only because they were completely reliable while the critical thinking parts of the brain were growing. The issue is not that part of the brain is outputting garbage, but rather, that it suddenly starts outputting garbage after a lifetime of being trustworthy. If part of the brain was unreliable or broken from birth, then its wiring would be forced to go through more sanity checks.
This is exactly what happened to my father over the past few years. His emotional responses have increased dramatically, after fifty years of regular behaviour, and he seems unable to adapt to these changes, leading to some very inappropriate actions. For example, he seems unable to separate “I feel extremely angry” from “There is good reason for me to be upset.”
Attempts to reason with him don’t generate ansognosiac-level absurdities, as he mostly understands that something unusual is going on, but it’s still a surreal experience.
In all seriousness though, I agree with you to an extent. Suggestions such as ‘all humans have tails’ or ‘some people who you think are dead are not, you just can’t see them’ - while surprising and creepy—would be extremely unlikely. I can see direct and obvious disadvantages to a person or species lacking such faculties. In fact, the disadvantages to those two would be so drastic that it would most likely lead to extinction.
And yet… I could still imagine us being blind to certain things. The first sort of blindness would be due to Darwinian irrelevance: for instance, many flowers have beautiful patterns visible in the UV spectrum, but there’s no reason for us to see them. That might seem mundane nowadays, but five hundred years ago it would have freaked people out (maybe). I wouldn’t be surprised that there are cognitive capabilities we’ve never suspected to exist.
The second sort of blindness is where it gets weird. True, our brains only allow trustworthy algorythms to bypass the logic circuits… or do they? The brain is not optimal. While I doubt we have invisible tails, that doesn’t mean that there isn’t some other phenomenon that we’re simply incapable of noticing even when it’s staring us right in the face.
This, applies more generally than to anosognosia alone, and was very illuminating, thank you !
So, provided that as we grow, some parts of our brain, mind, change, then this upsets the balance of our mind as a whole.
Let’s say someone relied on his intuition for years, and consistently observed it correlated well with reality. That person would have had a very good reason to more and more rely on that intuition, and uses its output unquestioningly, automatically to fuel other parts of his mind.
In such a person’s mind, one of the central gears would be that intuition. The whole machine would eventually depend upon it, and to remove intuition would mean, at best, that years of training and fine-tuning that rational machine would be lost; and a new way of thinking would have to be reached, trained again; most people wouldn’t even realize that, let alone be bold enough to admit it and start back from scratch.
And so some years later, the black-boxed process of intuition starts to deviate from correctly predicting reality for that person. And the whole rational machine carries on using it, because that gear just became too well established, and the whole machine lost its fluidity as it specialized in exploiting that easily available mental ressource.
Substitute emotions, drives for intuition, and that may work in the same way too. And so from being a well calibrated rationalist, you start deviating, slowly losing your mind, getting it wrong more and more often when you get an idea, or try to predict an action, or decide what would be to your best advantage, never realizing that one of the once dependable gears in your mind had slowly been worn away.

Oooooh! You’re no fun anymore!

Just in case anyone is curious about this:

I would really like this to be true. But is there evidence for it?
