The Bell Tolls for Folk Psychology: Are Societies Ready for a Public Health Quarantine Model of Criminal Justice?

Criminal laws and their deserts-based punishments, particularly in Anglo-American systems, remain grounded in folk psychology assumptions about free will, willpower, and agency. Yet advances in neuropsychiatry, neuromicrobiology, behavioral genetics, multi-omics, and exposome sciences, are revealing how here-and-now decisions are profoundly shaped by antecedent factors. This transdisciplinary evidence increasingly undermines the folk psychology model: some argue it leaves “not a single crack of daylight to shoehorn in free will”, while others suggest the evidence at least reveals far greater constraints on agency than currently acknowledged. Historically, courts and corrections have marginalized brain and behavior sciences, often invoking prescientific notions of monsters and wickedness to explain harmful behavior—encouraging anti-science sentiment and protecting normative assumptions. Earlier disciplinary silos, such as isolated neuroscience or single-gene claims, did little to challenge the system. But today’s integrated sciences—from microbiology and toxicology to nutrition and traumatology, powered by omics and machine learning—pose a threat to the folk psychology fulcrum. Resistance to change is well known in criminal justice, but the accelerating pace of biopsychosocial science makes it unlikely that traditional assumptions will endure. In response to modern science, emergent concepts of reform have been presented. Here, we review the public health quarantine model, an emergent concept that aligns criminal justice with public health principles. The model recognizes human behavior as emergent from complex biological, social, and environmental determinants. It turns away from retribution, while seeking accountability in a way that supports healing and prevention.
