Ethical considerations in cultural anthropology include obtaining informed consent from research participants, ensuring confidentiality, and respecting the autonomy and dignity of the people being studied. Anthropologists must avoid causing harm and strive to represent their subjects accurately and fairly. They also need to be aware of power dynamics in the research relationship and consider the potential impacts of their work on the communities involved. Ethical guidelines and codes of conduct, such as those provided by professional associations, help guide anthropologists in navigating these challenges.
