ABSTRACT
A key ethical notion in environmental research is that participation in a study must be completely voluntary. One of the things that made the various Nazi experiments so ethically heinous is that the subjects of the experiments were given no choice but to participate. The history of research is littered with examples of research projects where ethically questionable decisions were made. In some cases, they involved violating norms of basic decency regarding the proper way to treat other people. This chapter considers a few notorious examples of research that have raised various ethical issues. The examples are Milgram obedience experiment, The Stanford prison experiment, India driver's license study, Facebook mood contagion study. The Milgram obedience experiment, the Stanford prison experiment, the India driver's license study, and the Facebook mood manipulation study all illustrate some potential ethical pitfalls of conducting research.
