Name a principle from the Declaration of Helsinki applicable to research ethics.

A principle from the Declaration of Helsinki that is applicable to research ethics stresses that research involving human subjects must be based on a thorough understanding of the literature. This principle emphasizes the importance of grounding research work in existing knowledge to ensure that studies are relevant, scientifically sound, and ethical.

By ensuring that researchers are well-informed about previous studies, they can identify gaps in knowledge, avoid duplicating past research unnecessarily, and build on established findings, which contributes to the advancement of knowledge in a responsible manner. This foundational understanding is critical for conducting ethically responsible research that respects the dignity, rights, and welfare of participants.

The other options presented violate or misinterpret fundamental ethical principles outlined in the Declaration. Consent from participants is a cornerstone of ethical research practices, and both financial gain for researchers and altering findings for publication compromise the integrity of research and violate ethical standards.
