I think every person sometimes behaves just like IYI. IYIs are just a good illustration of human ignorance. Remember Robert Sheckley's Ask a Foolish Question book? Two clever scientists challenged The Answerer with their questions. This machine knew everything about the world, but failed to give any answer, because their questions were wrong. Anyone can read a clever book and think he/she knows something without really knowing it at all.
