🚨 New publication! ✅ Most risk tools use simple points systems--1 point per item, summed into a risk score ➡️ Millions of individuals can share the same score with completely different risk profiles ✅ We show how this leads to misclassification and propose a simple fix

It was a pleasure talking with Jen about my paper (and other cool research in this space). Thanks for having me!
A big challenge w CBT programs is finding a version that replicates at scale & is still effective. One reason this paper is important is that it measures the impact of a clearly-defined program that’s active in all prisons in Quebec. For inmates on the margin of participating, it reduces recidivism! Check out my interview w @williamarbour for more.
