Neurodivergence is showing up across legal systems with measurable effects on outcomes. In the UK, 1 in 3 people in contact with the police has a neurodivergent condition, but only 20% of neurodivergent defendants receive appropriate courtroom adjustments due to limited training. The same lack of support ripples into safety and equal treatment beyond the courtroom.
Key Takeaways

- Autistic people are 7 times more likely to have contact with the police than the general population

- JPMorgan Chase reported that neurodivergent employees were 90% to 140% more productive than other employees after training
