The Belmont Report outlines three fundamental ethical principles that guide research involving human subjects: respect for persons, beneficence, and justice.

Respect for persons emphasizes the importance of recognizing the autonomy of individuals and protecting those with diminished autonomy, ensuring that participants are treated as autonomous agents capable of making their own decisions about their involvement in research. This principle also necessitates obtaining informed consent from participants, allowing them to make informed choices about their participation.

Beneficence refers to the obligation to minimize harm and maximize possible benefits to the participants involved in research. This principle underlines the importance of ensuring the welfare of participants and highlights the moral imperative to conduct research that contributes positively to society while safeguarding participants' well-being.
