Plain English Campaign: Annual Awards

Reports that say that something hasn’t happened are always interesting to me, because as we know, there are known knowns; there are things we know we know. We also know there are known unknowns; that is to say we know there are some things we do not know. But there are also unknown unknowns — the ones we don’t know we don’t know.

This kind of obfuscated gibberish is more common than we realize. At the startup I worked at 2000, the VP of engineering referred to “unk unks” or unknown unknowns. That was my first exposure to that, but I’m guessing it’s not uncommon in the defense/aerospace establishment (that fellow was a Boeing alumnus).
