Principles in this wiki are categorized by evidence or level of acceptance. The principle is marked questioned if and only if someone has expressed reasonable arguments against it. It doesn't matter who questioned the principle but there has to be some understandable reason. Furthermore the principle itself needs to be questioned. It is not sufficient that keeping the rule may inevitably also have some negative effects expressed by another principle. This is normal due to the nature of the principle definition used here. A principle is questioned if the positive effect it claims is questioned.
