Chesterton's fence: don't remove what you don't understand.
In 1929, G. K. Chesterton described a fence in the middle of a field. The modern reformer says: 'I don't see the use of this, let's clear it away.' The wiser one replies: 'If you don't see the use, go and find out why it's there first.' Many old rules, rituals and buildings solved problems that reappear once they're gone.
Useful: Before you scrap an old rule in your team, ask someone who was there when it was made.
