This document outlines an introduction to research ethics. It discusses the objectives of understanding ethics and the difference between covert and overt research. Covert research has benefits like understanding internal issues but risks the researcher's safety, while overt research has benefits of honesty but risks people hiding sensitive issues. Both have pros and cons, but overt research should generally be preferred. The document also covers ethical principles of autonomy, beneficence and justice. It discusses codes of ethics involving informed consent, privacy, confidentiality and avoiding deception. The goal is for researchers to treat participants with honesty and respect.
