In an age of rapidly evolving AI, we are *just* starting to learn how we can properly regulate these powerful new technologies. While many new regulations will be well-intended, we won't know what really works until we try many different approaches.

.@counciloncj.org just released a comprehensive guide to help justice agencies make the right decision about whether and how to adopt AI. This guide reflects many productive discussions we've had on the Task Force for AI over the last year—kudos to CCJ for distilling this into a practical guide!

As criminal justice agencies and practitioners face urgent questions about how to effectively and safely adopt AI tools, CCJ's Task Force on AI released a new decision guide to help stakeholders evaluate, implement, and oversee AI in the justice system. counciloncj.org/assessing-ai...

Have you ever forgotten an important date—like a birthday for a loved one? Now imagine if forgetting meant ending up in jail. Two years ago, we ran a randomized experiment that found that text message reminders reduce jail stays for missed court dates by over 20%.

Yes to evaluating the *outcomes* of these systems rather than as a standalone algorithm! This is something that's been bothering me for a while about ML assisted decisions

NEW in Management Science! My coauthors and I came up with a new consequentialist approach to designing equitable algorithms. Instead of imposing fairness criteria on an algorithm (like equal false negative rates), we aim for good outcomes. More in the 🧵 below! (1/)

The use of race in clinical risk models is heavily debated. While race-aware models can be more accurate, some are concerned about reinforcing racialized views of medicine. In our paper, we offer a new perspective on this debate. 🧵👇https://annals.org/aim/article/doi/10.7326/M23-3166

In AI research, more and more of the action seems to be taking place above the foundation model layer and is closer to applications / people / societal impact. This kind of research strongly benefits from interdisciplinary thinking (though not all AI researchers have recognized the shift yet!)

🔬 Major new findings on STEM gender gaps: Looking across institutions over time, physics, engineering & computer science (PECS) show stark divides—gaps are closing at selective colleges but widening elsewhere. w/ @joalkhafajiking.bsky.social [<--🌟 on the job market 😉] www.science.org/doi/10.1126/...

The Stanford Report just featured our research on using automated reminders to reduce pretrial incarceration — alongside two other terrific Stanford Impact Labs funded efforts thinking about how to achieve both research impact and social impact!

We are working on two new experiments at the Santa Clara Public Defender Office. Check out this piece from Stanford Impact Labs to learn more! I'm so glad my colleague Sarah at the public defender was included to explain why this research is important to her. impact.stanford.edu/article/can-...
