hi ... re "It's not what you don't know that worries me; it's what you think you know."

then there's Donald Rumsfeld ...

"There are known knowns.
These are things we know that we know.
There are known unknowns.
That is to say, there are things that we now know we don’t know.
But there are also unknown unknowns.
These are things we do not know we don’t know."
