I just added up the number of years Americans have spent in prison 1979-2021: 48.5 million. In the figure below, each square represents a million years spent in prison, an unfathomable number. 1/4

New paper in PNAS: Your homicide risk follows you around the country. If you’re born in the historically violent Wild West, Appalachian Highlands, or Deep South, a higher risk of violent death trails you wherever you go. 🧵1/13

6 Princeton faculty propose to “refrain from any form of academic or cultural association with Israeli institutions and businesses.”
No talks at Israeli unis? No collabs w Israeli scholars? That’s not a protest of a government’s policy. It’s a call to ostracize a people.
No.

I find this letter by Jewish students at Columbia to clearly describe a lot of my experience as a Jewish and Israeli student at Princeton for the past months. I urge members of the Princeton community to read it, even if only to better understand another aspect of the protests

For the Global City Crime Benchmarking project, a team of multi-lingual colleagues and I compared crime in 20 of the largest cities in the developed world. I’ll do a thread next week on the results.

We need this to be an ongoing, routine standard practice, not a one-off.
Honestly, this is closer to what peer review should actually be like.
Our first meta paper is out!! This paper combines our first 110 completed reproductions/replications. This is joint work with 350+ amazing coauthors.
We summarize our findings below.

Banning the purchase of sex 🚨DOES NOT🚨increase cases of reported rape.
A re-analysis of Ciacci (2024) shows that the paper's headline result comes from an erroneous use of Stata's regression command.

This, not sentencing reform by progressive DAs, is the real story of criminal justice policy in the US in the 2020s. Police can hold any local political system hostage.

It's insane how in multiple US cities the police got so mad they faced any sort of criticism or accountability they completely stopped working

In the criminal justice system, the people are represented by two separate groups: The district attorneys, who are elected by voters and prosecute the offenders, and the police, who do whatever they want.
