AI Insight
This review article examines how people judge whether risks are acceptable, finding that such judgments depend not only on probability calculations but also on psychological factors including risk perception, trust in those managing the risk, and perceptions of fairness. The authors propose a framework distinguishing between self-controlled risks, risks controlled by others, and collectively mandated risks, arguing that each configuration differently weights perceived threat, institutional credibility, and legitimacy. This explains why technically similar risks receive different levels of public acceptance depending on social and institutional context.
Why it matters
Understanding the psychological basis of acceptable-risk judgments has important implications for risk communication, public policy, and regulatory decision-making. The framework can help explain public resistance to certain technologies or policies and guide more effective stakeholder engagement when hazards must be managed collectively.
Understand the Science
Acceptable risk is often defined in technical, regulatory, or ethical terms. Yet people do not decide that a risk is acceptable simply by estimating probabilities or expected harms. Judgments of acceptability are also shaped by how a hazard is perceived, whether those responsible for managing it are trusted, and whether exposure is regarded as fair. This mini review brings together research on risk perception, trust, and fairness to show how acceptable-risk judgments are formed within interpersonal configurations of exposure, control, and justification. The framework distinguishes primarily self-regarding risks, other-controlled risks, and collectively governed or mandated risks, arguing that these configurations affect the relative salience of perceived threat, institutional credibility, and legitimacy. This perspective helps explain why technically similar risks may be tolerated, contested, or rejected across settings. It also identifies implications for future research on risk communication, public judgment, and the psychology of legitimacy.
