We have understood basic playground rules since childhood: (1) don’t hit other people, and (2) don’t steal their stuff. As adults, we strive to adhere to these rules, even though we’ve moved beyond the playground and into a bigger, more complex world.
But what happens when we break those rules? Are there principles working as we interact that make playground rules the backbone of personal relationships and a civil society? Everyone knows how gravity works, but do the actions of individuals have similar cause-and-effect relationships that are just as predictable?
