Let’s say you are a mayor of a city. You have the power to change anything. An extremely critical situation has occurred in your city. You are very worried. You have two options to choose and you decided to chose one. Before going to announce it publicly you saw on the television that some people(around 10%) from your city are protesting against the decision you are going to tell them. It is given that majority of your population do not bother with your decision.
The question is how do you measure the correctness of your decision at this point?
