Which of the Following Statements Most Clearly Illustrates the Principle of Beneficence?

The answer

The correct choice is the statement that focuses on weighing benefits against harms — such as "the researcher assesses whether the potential benefits of the study justify the risks to participants" or "the study is designed to maximize benefits and minimize possible harms." That is the essence of beneficence.

Beneficence is one of the three principles of the Belmont Report (1979), the foundational U.S. ethics document behind CITI training and the Common Rule. Beneficence obligates researchers to (1) do no harm and (2) maximize possible benefits and minimize possible harms. In practice it is operationalized through risk-benefit analysis by researchers and Institutional Review Boards (IRBs).

The three Belmont principles side by side

The reason this question is tricky is that the distractors describe the other two Belmont principles, which sound ethical but illustrate something different:

• Respect for persons — treating individuals as autonomous agents and protecting those with diminished autonomy. It is illustrated by statements about informed consent, voluntariness, and safeguarding vulnerable populations. A choice mentioning "obtaining voluntary informed consent" is respect for persons, not beneficence.
• Beneficence — the systematic assessment of risks and benefits; "do no harm" and "maximize benefit, minimize harm." This is the answer.
• Justice — the fair distribution of the burdens and benefits of research; who bears the risks and who reaps the rewards. A choice about "selecting participants equitably" or "not exploiting a vulnerable group to benefit others" illustrates justice, not beneficence.

Why the distractors are wrong

A statement about getting participants' informed consent illustrates respect for persons — it concerns autonomy and decision-making, not the balancing of harm and benefit. A statement about fairly choosing who is enrolled or ensuring one group isn't unfairly burdened illustrates justice — it concerns equitable distribution. A statement about simply following the law or protecting confidentiality may be good practice but does not map onto the specific benefit-versus-harm calculus that defines beneficence.

Only the statement that explicitly frames the decision as are the benefits worth the risks? captures beneficence.

Beneficence vs. nonmaleficence

Students sometimes ask how beneficence differs from nonmaleficence ("do no harm"). In classical biomedical ethics these are two separate principles, but the Belmont Report folds "do no harm" into beneficence as its first component, then adds the affirmative duty to maximize benefits. So on a CITI/Belmont exam, both "avoid harm" and "weigh benefits against risks" fall under beneficence.
