Harm-benefit, also termed harm-benefit analysis or harms-benefit assessment, is a decision-making framework used to evaluate actions, policies, or interventions by weighing their potential harms against their potential benefits. It is employed across disciplines such as medicine, public policy, law, and environmental management to support ethical justification and resource allocation. Unlike risk-benefit analysis, which emphasizes probabilities of adverse outcomes, harm-benefit analysis foregrounds the moral or practical significance of harms and benefits, including their severity, likelihood, and distribution.

Methodology typically involves identifying relevant harms and benefits for affected parties, estimating their magnitude and probability, and comparing net effects. The assessment may incorporate qualitative judgments, quantitative estimates, or both, and often considers uncertainties, opportunity costs, and distributional impacts across groups. Ethical frameworks—such as utilitarian calculations, deontological constraints, or principles of beneficence and non-maleficence—may guide how harms are weighed and what thresholds determine acceptability. In research ethics, harm-benefit assessment is used by review boards to balance participant risks against potential social value or scientific knowledge.

Applications include clinical trials, public health interventions, environmental regulation, and technology deployment. For example, a clinical trial may be approved when the expected benefits to participants or society outweigh potential risks, whereas a policy proposal might be judged by net improvements in well-being and risk reduction.

Critics note that the framework can be subjective, difficult to quantify, and sensitive to value assumptions, discounting, and distributional considerations. Critics also warn against allowing aggregate benefits to obscure harms to minority or vulnerable groups, or to justify harmful practices under the banner of overall gain.

While widely used, harm-benefit analysis remains contested and is often complemented by other ethical and legal safeguards to ensure due process and equity.
