Alternatively there are many people who dont know every rule, and see some insignificant behaviour as normal. and so are not following suit, like a lemming, just behaving in a way they always have.
Like at work, I see processes and procedures as a guide, not a rule book. (Not talking health and safety here for the pedants)
Processess and procedures if followed to the letter, make any chance of lateral thinking impossible.
Are these the sort of rules you are talking about?
