more sources needed

Regarding your edit to Murphy's Law. I googled the Human Factors version "if the system enables the users to fail, eventually they will". It is only featured in one of your papers, I can't find anyone else using it. Thus, I can't endorse this addition, and I have reversed it. --Enric Naval (talk) 10:46, 31 December 2012 (UTC)
