As more departments and companies began experimenting with predictive policing, government-funded research cast doubts on its efficacy, and independent academics found it can have a disparate impact on poor communities of color. A 2016 study reverse-engineered PredPol’s algorithm and found that it replicated “systemic bias” against over-policed communities of color and that historical crime data did not accurately predict future criminal activity. One of the researchers, a Michigan State PhD candidate named William Isaac, had not previously heard of New Orleans’ partnership with Palantir, but he recognized the data-mapping model at the heart of the program. “I think the data they’re using, there are serious questions about its predictive power. We’ve seen very little about its ability to forecast violent crime,” Isaac said.
