Act utilitarianism Individual Relativism General utilitarianism Virtue Ethics Rule utilitarianism Preference Utilitarianism Custom Ethics Truth Ethics Ethical relativism Kantian ethics Match the ethical theory with the duty to tell the truth: An ethical theory holds that we should always tell the truth. An ethical theory holds that society determines if we have a duty to tell the truth. The consequences determine if we have a duty to tell the truth. If the consequences are good, we should tell the truth. If not, we should not tell the truth. If society benefits from our having a duty to tell the truth, we should always tell the truth, even if it is sometimes counter-productive. To find out if we have a duty to tell the truth an ethical theory holds that we should ask the question: What would happen if everybody else considered not to tell the truth?
