Punishment guarantees a push-back response.
When a parent resorts to punishment both the parent and the child begin to pay attention to the punishment and its fairness and being sure that it enforced. This allows the child to stop thinking about the decision process that brought about the negative behavior in the first place. Next, the child is not engaged in the process of creating a thought process that will bring about better outcomes next time. When we resort to punishment it gives children someone to be mad at. And, when they are mad they do not have to face their own behavior because anger takes over and interrupts responsible thought.
