When you think about it, the very foundations of daily life rest on trust. Every time we get in the car, we trust that most drivers will operate vehicles safely and according to traffic laws. We trust that our physicians will do their best to provide us with good medical care. We trust that the police officer who pulls us over for speeding will treat us with fairness and respect. We trust that the check-out clerk at the supermarket will not cheat us. In short, in order to move through the world most effectively, we must trust that most people are acting on good faith and doing the best they can.
