Which of the following is an ethical principle that guides research involving human subjects?

Beneficence is a fundamental ethical principle guiding research involving human subjects. This principle emphasizes the obligation of researchers to prioritize the welfare and rights of participants. In practice, beneficence involves taking measures to minimize any potential risks and harm that could arise from participation in research, while maximizing potential benefits. It reflects a commitment to ensuring that the research contributes positively to the well-being of participants and society at large.

By focusing on reducing risks and avoiding harm, beneficence aligns with the broader ethical mandate to treat participants with respect and dignity. This principle is critical in fields like medical and psychological research, where the stakes of participant safety are particularly high. Therefore, adherence to beneficence helps to foster trust in the research process and upholds the integrity of scientific inquiry.

The other choices do not align closely with the ethical standards expected in research involving human subjects. For instance, utilitarianism, while it does consider the outcomes of research, can be problematic if it prioritizes outcomes over individual rights and welfare. Neutrality may not necessarily involve the active prioritization of participant well-being, and maintaining distance might inhibit the ethical obligation to foster a supportive research environment. Lastly, authoritarianism contradicts the principle of informed consent, which is a core aspect of ethical
