The respected leader Winston Churchill was also famous for leading his subordinates well. To the person whom he wanted to proceed with a task quickly, he said, “You seem to be quick to make a decision,” and to the person whom he wanted to get things done perfectly, “You look scrupulous.” Instead of telling directly what he wanted, he said as if the person had such a tendency.
If you say to the other person, “You are like this person,” the person will behave as you expected. In psychology, this is called “label effect” or “letter effect.”
Even an unfriendly person tries to be kind if he is told, “You look kind.” On the other hand, when a person is told, “You are useless” or “You are a very selfish person,” even the normal person becomes useless and selfish.
Depending on what you say, the other person may change in action. If you want to lead people around you and your family to a positive change, please put a good label on them first.
