Known Knowns and False Truths

The "unknown unknowns" concept (long predating its popularly attributed source) can be extended by looking at the ground-truth and believed-truth status of information

This gives a total of 16 states:

KKTT KKTF KKFT KKFF
KUTT KUTF KUFT KUFF
UKTT UKTF UKFT UKFF
UUTT UUTF UUFT UUFF

I'm not entirely certain how useful this is, though it seems useful to think about information, knowledge, truth, and falsity.
