A lot of us throughout our lifetime have been in situations where we were expected to act as the decision makers, judging what the right course of action in moral, civil or logistical matters would be. This happens often for example, if you’re a parent, a police officer, a priest, a choir conductor, a business manager, etc, but it can also happen if two of your friends are in a dispute and you’re the third party expected to play the role of arbiter. It is easy to see how this necessary role would almost naturally be a vital element to keep any society running in an orderly fashion.
