The thing about ethics is....

Ethical judgement limits the methods available in the production of knowledge in both the arts and the natural sciences. Discuss.
Say what you want, unethical research is responsible for a lot of valuable scientific findings. Unethical research has led to great understandings. As disgustingly vile as it was, the Nazi medical experiments in the concentration camps provided anatomical findings that the United States would come to use later on. The "Baby Albert" experiment, which was conducted on orphans, conditioned infants and toddlers to fear anything fluffy and white by pounding a gong every time a white lab rat was shown to the test subjects. Clearly unethical, this research provided a lot of introspection on the field of psychology and assisted in validating the behaviorist perspective. Ethics limit production but are necessary to retain humanity in science.
