There are known unknowns; that is to say, there are things that we know we don’t know.
But there are also unknown unknowns; things we do not know we don’t know.”
– former Secretary of State Donald Rumsfeld
I read these words of Donald Rumsfeld, and the words make me wonder: Why’d you leave out the unknown knowns, Don? The things that we do not know that we know?
That’s what this blog post is all about. Unknown knowns.
