We have finite time and money for pursuing research, and the wisdom of research programs is a very valid question in research ethics. It is possible to give a short answer to all of these questions. Everyone involved in science should be taught the responsible conduct of science in every course, in every setting possible, and at every level of education by every responsible teacher of science. Yes, because the responsible conduct of science is vitally important. Science touches everyone s life nowadays, and the responsible conduct of research concerns everyone.
Public money funds most research.
No one is too young or too old to learn something about research ethics. Any time research techniques are taught, the responsible use of those techniques should be taught. Then again, I am not completely serious about this that research ethics should be taught everywhere by everyone because I know it is not practical. Let me, then, sketch out a few more limited and practical ideas. Undergraduate students can be taught research ethics.
