on "John", the article said "The problem with John was not just that he was misinformed, but that he was misinformed and highly motivated."

I'm reminded of this quote:

"I divide officers into four classes -- the clever, the lazy, the stupid and the industrious. Each officer possesses at least two of these qualities. Those who are clever and industrious are fitted for the high staff appointments. Use can be made of those who are stupid and lazy. The man who is clever and lazy is fit for the very highest commands. He has the temperament and the requisite nerves to deal with all situations. But whoever is stupid and industrious must be removed immediately." - General Baron Kurt von Hammerstein-Equord
