Which ethical requirement is essential in research involving human participants?

• A. Randomization
• B. Informed consent
• C. Deception allowed
• D. Anonymity

Answer: (B)

Informed consent is the essential requirement in research involving human participants. It protects autonomy by ensuring people understand what the study involves—the purpose, procedures, potential risks and benefits, and any alternatives—before agreeing to participate. It also makes participation voluntary and allows individuals to withdraw at any time without penalty. This ongoing, voluntary agreement is foundational for ethical research and is typically supported by IRB oversight and clear, accessible information. While the study design may involve methods like randomization or considerations around anonymity or confidentiality, those elements are not the fundamental ethical gatekeeper. Deception, though sometimes used under strict controls, is not universally required and must be carefully justified and disclosed to participants, often with debriefing afterward. Anonymity is desirable but not always feasible or required in every study. The core ethical standard that enables participation and protects individuals is obtaining informed consent.
