known unknown

Something that one knows they don't know.

There are known unknowns, that is to say that there are things that we know we don't know. (whiskey tango foxtrot, Donald?)

Unknown knowns

Donald Rumsfeld pithy description of an old southern saying.

Rumsfeld says 'unknown knowns', down here we say, 'He's so fucking stupid, not only doesn't he know nothin', he don't even suspect it.'
