Ethical principles in research refer to the set of guidelines and norms that govern the conduct of research and protect the rights and welfare of research participants. These principles include respect for autonomy, beneficence, justice, and honesty. Researchers are expected to obtain informed consent from participants, ensure participant confidentiality, avoid causing harm or deception, and fairly distribute the benefits and burdens of research. Adhering to ethical principles in research is essential to maintain the integrity and credibility of scientific inquiry and protect the rights of individuals involved in research studies.
