What do we know

Known knowns
What you know you know. Verified facts. Very little conflicting information.

Known unknowns
What you know about, but you don’t really know. Rumors, finger pointing, things that need to be investigated.

Unknown unknowns
What you have no idea about. Just because you don’t have the information doesn’t mean it doesn't exist. This is not just there to acknowledge the completion of the statement. It is a legitimate means of telling the level of information about a subject.

The furor over this statement revealed more about the people covering the story than the subject of the story. I remember one of the BBC commentators saying “This makes perfect sense.” and many of the other people working with him saying it was insane and made no sense at all. This is a left brained statement. The commentator who got it was a person whom I thought got a lot of things.

Another situation that this reminds me of is  in the movie “District 9” There is a scene where a group of engineers and scientists are diagnosing the man’s condition. They try several different things as they figure out what does and does not work with the man converting into an alien and the alien technology that up to this point they have been baffled by. It made perfect sense to anyone who had ever diagnosed anything in their lives.
