Research is unethical if it fails to ensure the privacy and anonymity of the respondent.

Trying to prove a particular point is a bias concern, not the core ethical breach here.

Protecting identity and personal information is a central duty in research ethics.

Informed consent and confidentiality together safeguard participants from harm.
