Law, Order & Algorithms: A Computational Approach to Criminal Justice
Sharad Goel, Stanford University
Statistical and algorithmic methods are increasingly used throughout the criminal justice system, from predictive policing to sentencing. I'll discuss two recent applications of this approach: (1) real-time risk assessments for stop-and-frisk and for bail decisions; (2) tests for discrimination in traffic stops. For the former, I'll argue that simple, statistically informed heuristics can outperform expert human decision makers in both efficiency and equity. For the latter, I'll show that popular tests for racial bias suffer from subtle flaws, and will propose a new method for measuring discrimination.
