There are five types of known.
The Rumsfeld three:
- Known knowns: Things you do know you know;
- Known unknowns: Things you do know you don’t know;
- Unknown unknowns: Things you don’t know you don’t know;
And the Jolly Contrarian two:
- Unknown knowns: Things you don’t know you do know.
- Not officially known: Things that you do know but the general public can’t prove.
