Introspection doesn't yield any scientific results. In most cases what's
happening under the hood is profoundly counterintuitive. I seem to recall
one study where a motoric reaction was already determined well before the
subject was aware of it.
I guess current consensus at a highly trivial level says the "I" is just a
surfer over miles of murky depths of down below. The majority of what's
happening is unaccessible to self, in a certain sense the self is a
signature of deeply buried activity.

This question is meaningless. Whether we are FSMs, or quantum systems,
pseudorandom is fundamentallx indistinguishable from true random. We just
can't tell. It doesn't make one iota of difference from the user front

QM is not just a good idea, it's the law.

Again, you are trying to gain knowledge from introspection. It's futile.

Such a trait does not appear to be meaningful in evolutionary context.
For what's this worth, one could probably make memories kinetically
inaccessible by autosuggestion. Not that I tried. What does the
