Social neuroscience, grounded in social psychological theory, provides policy-relevant insights by identifying mechanisms through which social factors influence the human brain, physiology, and behavior. Neural mechanisms illuminate social problems and potential interventions relevant to public policy; for example, social neuroscience has provided insights into inequality and intergroup bias, loneliness, and trust. Social neuroscience research on perceived social threat, reward, and theory of mind clarifies how social inequities, social isolation, and discrimination produce enduring consequences for health outcomes and social decisions (e.g., employment, judicial, or educational). Neural insights also reveal flexibility in responses through diverse contact, social connection, and procedural justice. Emphasizing methodological and theoretical rigor, the translation of social neuroscience research informs potential policy applications. For example, structural reforms can reduce stressors, programs can cultivate connection, and institutional practices can increase transparency and fairness. Ethical guardrails, such as avoiding neuro-determinism, protecting neural data, and ensuring representativeness, are essential for responsible use. Policy recommendations can accelerate and strengthen psychologically anchored social neuroscience, informing evidence-based, humane governance through sustained funding, shared infrastructure, accessible education, and effective communication channels between researchers and policymakers.
