The study challenges assumptions that teenage behavior is too entrenched to change, showing that low-cost, evidence-based psychological interventions can disrupt cycles of violence. Because violence naturally declines with age, even short-term reductions during peak years can meaningfully lower lifetime criminal involvement.", "key_takeaways": ["A brief, low-cost CBT program reduced violent-crime arrests by 44% among high-risk Chicago teens during the intervention year.", "Traditional mentoring and job programs costing $15,000 per student showed no measurable impact on
