Trying juveniles as adults produces modest safety effects at high cost
Prosecution of juveniles as adults produces modest crime reduction but with high human and fiscal costs. Alternative approaches may achieve similar safety benefits more efficiently.
Transfer to adult courts does not deter youth crime more effectively than juvenile court. Longitudinal studies show transferred youth have equal or higher recidivism than comparable youth retained in juvenile court. Transfer undermines rehabilitation, increases adult criminalization, and produces worse life outcomes. The mechanism of deterrence assumes juveniles make rational cost-benefit calculations; developmental neuroscience shows adolescent brains are still developing judgment capacity.

Premise Assessment
Is the claim as stated true? Four dimensions, each 0–25, sum to 100. The verdict label is derived from this score. Full rubric →
Quality and quantity of direct evidence for or against the claim — RCTs, systematic reviews, natural experiments, large cohort studies.
Evidence strongly contradicts deterrence claim: Hahn et al.'s (2007) CDC Task Force review and Bishop & Frazier's Florida studies find transferred youth reoffend more, not less.
Whether the proposed mechanism is valid and established — does the how make sense, or are there fundamental flaws in the causal logic?
Deterrence logic assumes rational cost-benefit calculation; adolescent development research shows juveniles discount future consequences heavily, undercutting the mechanism.
Degree of agreement among domain experts and relevant scientific or policy bodies — depth and quality of consensus, not just majority opinion.
Developmental and criminology experts broadly agree transfer increases harm and reduces rehabilitation prospects relative to juvenile-system retention.
Whether findings hold across independent studies, populations, and contexts — resistance to p-hacking and publication bias.
Consistent findings across jurisdictions (Florida, NY/NJ border comparison) show increased recidivism post-transfer; no jurisdiction studied shows a safety improvement.
Individual vs. Structural
How much of the outcome is explained by structural forces versus individual agency? Four dimensions, each 0–25. Higher scores indicate stronger structural causation. Full rubric →
