That is a further complication. Statisticians often must work on interdisciplinary teams. They face problems when all colleagues are subject to ethical codes or guidelines, but these may be somewhat different for each participant. Ethical issues are frequently intertwined with issues of law and politics. We hope not, but as you will see, it is hard to avoid an inadvertent misuse and we are as fallible as any other statistician.
Some statisticians argue for a separation of ethics and competence.
Well, honest disagreement about methods is ethical, of course, but we sometimes see abuses which exceed reasonable tolerance. Because of the full complexity of ethical issues in a large, diverse universe of contrasting environments, applications, and collaborative structures, some feel that the only tractable problem is deciding how to teach statistical ethics to students. After all, this cannot be expected to deal with all possible issues. Some new issues arise in teaching, as opposed to defining, statistical ethics. First, some insist that no student can truly understand ethics, as opposed to memorizing enough words to pass a test, without a grounding in some philosophical theory of ethics.
