The point about communication is particularly important. Just "knowing" the situation is never enough. If you cannot explain it, you might as well not know it.
Take a look at Tufte's review of the graphics explaining the effect of temperature (cold) on shuttle o-rings at the run-up to the Challenger launch. The engineers "knew" what the problem was, but it was not communicated. The graphics actually hid the information (or at least obscured it). Richard Feynman's on-camera demo (not experiment - he knew what was going to happen) finally got it across. (Read his account of this in his autobiography, it shows how hard it is to communicate even the desire for a glass of cold water to some people.) Feynman at this point was the educator/communicator we needed.
