Which statement best describes the means by which benefits are evaluated in the risk-benefit assessment?

• A. Benefits must be guaranteed to occur.
• B. Benefits may include societal or participant advantages and should be meaningful.
• C. Risks must be minimized, but benefits do not need to be meaningful if risk is low.
• D. Benefits should exceed all possible harms by a large margin.

Answer: (C)

In risk-benefit assessment, the focus is on whether the potential benefits are real and valuable, not merely hoped for. Benefits may include advantages for participants and broader societal gains, and they should be meaningful rather than vague or purely hypothetical. This framing fits ethical guidance that risks must be minimized and that research should offer plausible, worthwhile benefits, even if those benefits aren’t guaranteed to occur. It’s not required that benefits far exceed harms by a large margin or that they be guaranteed; rather, the assessment looks for meaningful, credible benefits in relation to the risks involved. The idea that benefits need not be meaningful if the risk is low conflicts with the expectation that meaningful benefits are expected to justify the research, even when risks are small.
