Somewhere on any given topic:
- I don't know that I don't know (ignorance)
- I know that I don't know (awareness of the existence of knowledge)
- I know that I know (active obtained knowledge)
- I don't know that I know (knowledge now part of the unconscious toolbox)
If I give you a crumb, realize that I may just be in a rush or don't know how to answer it properly.
