I prefer Slavoj Zizek classification into knowns and unknowns.
- Known-Knowns: things we know that we know
- Known-Unknowns: things that we know we don’t know
- Unkown-Unknowns: things we don’t know we don’t know
- Unknown-Knowns: “The things we don’t know that we know-which is precisely, the Freudian unconscious, the “knowledge which doesn’t know itself,” as Lacan used to say. “. This is better known as culture.
