Dunn's Law of Information

  • "What you don't know, you don't know - and you can't make it up".

This law is attributed to former Raytheon vice president Bruce Dunn. Although Bruce used it in the context of evaluation of evidence for scripture, it is highly applicable in the case of cluster failure where all that is observed is inability to communicate.

Because in this case, one knows very little - except that we can't communicate with the given node. Nevertheless, the temptation is great to pretend to greater knowledge.
