The Ethical Use of Unethical Human Research Medical research is conducted to aid and support the development of knowledge in the field of medicine. It provides us the opportunity to answer the unanswered questions in order to improve human health. Indeed, in order to make a progress in human health it is essential to conduct research with human subjects. Properly controlled studies with human subjects are essential to verify any conclusions about normal physiology, mechanisms of disease, effectiveness of treatment, learning, or behavior.
