A tale about Testing and Ignorance
He who knows not and knows not that he knows not, is a fool. Shun him!
He who knows not and knows that he knows not, is unlearned. Teach him!
He who knows and knows not that he knows, is asleep. Awaken him!
He who knows and knows that he knows, is enlightened. Follow him!
An Arab Proverb quoted by Isabel Lady Burton (1831-1896) in
"The Life of Captain Sir Richard F. Burton"

I don't know something, but I have a well formed question.
2OI = Lack of Awareness
I don't know that I don't know something. I have no idea what the right question is.
3OI = Lack of Process
I don't know a suitably way to find out I don't know that I don't know something.
I have no clue how to find the right idea's to search for the right question.
4OI = Meta-ignorance
I don't know about the Five Orders of Ignorance.
