Unconscious Incompetence
The individual does not understand or know how to do something and does not necessarily recognize the deficit. They may deny the usefulness of the skill. The individual must recognise their own incompetence, and the value of the new skill, before moving on to the next stage. The length of time an individual spends in this stage depends on the strength of the stimulus to learn
It's entirely possible to live your entire life (and a lot of people do) without ever realising there could possibly be anything deficient with your own reasoning capability, even though it may be dismal. It's one of those "you won't know it until you know it" things. I'm sure there are many things that I could be doing better, or am entirely ignorant of without even knowing there's something to be ignorant about. If the deficit is not made clear to me in unambiguous terms by someone who DOES know, or a pure fluke of reading, I'll never be the wiser.
It helps to read a lot and research as I am one to do. But a lot of people just don't spend their lives absorbing lots and lots of weird facts and bits about the world, so the chances of them running into the information by chance is greatly reduced.
I'm not saying this is great, nor am I saying someone shouldn't point at them and go "oy! Learn to reason!". But I mean that's kinda insulting, "Like what? I can't reason?! I'm WRONG about my whole worldview!? Screw YOU!".... the very problem of not appreciating objective reason can defeat a chance of actually obtaining an appreciation for it.
