Evaluating an Objective
Imagine the following scenario:
You and your team have been given balloons and are given the objective to keep AS MANY BALLOONS AS YOU CAN in the air for one minute. You cannot hold the balloons and you are permitted to help each other. Once a balloon drops to the ground, it is out.
You are competing against another team, whose goal is to keep ALL BALLOONS in the air for 1 minute. They cannot hold the balloons and they are permitted to help each other. Once one of their balloons drops to the ground, it is out.
Your team drops more balloons than the other team, yet you are rewarded with praise, while the other team is scolded for not achieving their goal.
