I share your sentiment that DK being a statistical phenomenon actually makes the effect more interesting. I also, however, think that you are being too semantically liberal when you insist that this proves the effect exists. The DK effect is a _psychological_ effect, with a whole lot of psychological theories around it's causes. If the cause is statistical, the psychological effect can no longer be said to exist. The stasticial phenomenon exists, surely - but I think it will be very confusing for everyone to re-use the same name.
