Palantir Has Secretly Been Using New Orleans to Test Its Predictive Policing Technology
One of the researchers, a Michigan State PhD candidate named William Isaac, had not previously heard of New Orleansâ partnership with Palantir, but he recognized the data-mapping model at the heart of the program. âI think the data theyâre using, there are serious questions about its predictive power. Weâve seen very little about its ability to forecast violent crime,â Isaac said.
Rise of the racist robots â how AI is learning all our worst impulses
âIf youâre not careful, you risk automating the exact same biases these programs are supposed to eliminate,â says Kristian Lum, the lead statistician at the San Francisco-based, non-profit Human Rights Data Analysis Group (HRDAG). Last year, Lum and a co-author showed that PredPol, a program for police departments that predicts hotspots where future crime might occur, could potentially get stuck in a feedback loop of over-policing majority black and brown neighbourhoods. The program was âlearningâ from previous crime reports. For Samuel Sinyangwe, a justice activist and policy researcher, this kind of approach is âespecially nefariousâ because police can say: âWeâre not being biased, weâre just doing what the math tells us.â And the public perception might be that the algorithms are impartial.
Can âpredictive policingâ prevent crime before it happens?
HRDAG analyst William Isaac is quoted in this article about so-called crime prediction. “They’re not predicting the future. What they’re actually predicting is where the next recorded police observations are going to occur.”
5 Questions for Kristian Lum
Kristian Lum discusses the challenges of getting accurate data from conflict zones, as well as her concerns about predictive policing if law enforcement gets it wrong.
Quantifying Injustice
“In 2016, two researchers, the statistician Kristian Lum and the political scientist William Isaac, set out to measure the bias in predictive policing algorithms. They chose as their example a program called PredPol. … Lum and Isaac faced a conundrum: if official data on crimes is biased, how can you test a crime prediction model? To solve this technique, they turned to a technique used in statistics and machine learning called the synthetic population.”
A Data Double Take: Police Shootings
“In a recent article, social scientist Patrick Ball revisited his and Kristian Lumâs 2015 study, which made a compelling argument for the underreporting of lethal police shootings by the Bureau of Justice Statistics (BJS). Lum and Ballâs study may be old, but it bears revisiting amid debates over the American police system â debates that have featured plenty of data on the excessive use of police force. It is a useful reminder that many of the facts and figures we rely on require further verification.”
The True Dangers of AI are Closer Than We Think
William Isaac is quoted.
Data-driven crime prediction fails to erase human bias
Work by HRDAG researchers Kristian Lum and William Isaac is cited in this article about the Policing Project: “While this bias knows no color or socioeconomic class, Lum and her HRDAG colleague William Isaac demonstrate that it can lead to policing that unfairly targets minorities and those living in poorer neighborhoods.”
What happens when you look at crime by the numbers
Kristian Lum’s work on the HRDAG Policing Project is referred to here: “In fact, Lum argues, itâs not clear how well this model worked at depicting the situation in Oakland. Those data on drug crimes were biased, she now reports. The problem was not deliberate, she says. Rather, data collectors just missed some criminals and crime sites. So data on them never made it into her model.”

The Washington Post’s Paul Schemm recognized HRDAG’s work in Syria, in the category of research and activism. “HRDAG gained renown at the start of the war, when it was one of the few organizations that tried to put a number on the warâs enormous toll in Syrian lives.”
