Cory Doctorow - Pluralistic: Daily links from Cory Doctorow - 4 August, 2026

Obviously, the non-American world has a digital sovereignty problem – Trump has means, motive and opportunity to order his tech companies to shut down any public official, large corporation, or individual who displeases him. In a world dominated by tech monopolies, duopolies and cartels, there’s every reason in the world to seek protection and insulation from these companies that are “too big to care” – and yet, the very same dominance that makes these companies such a danger also makes them indispensable.

“They’re one of the most important NGOs that no one’s ever heard of. … What they do is very rigorous statistical extrapolations of information that’s not in the record, about wars, civil wars, coups, oppressive states, and they’re used for truth and reconciliation, human rights tribunals, war crimes trials. … They’ve worked on every high-profile war crimes trial in the century.”

“You look at all the huge problems in the world, and you are trying to find ways to plug in. And it turns out—whether it is cooking a meal for somebody who’s hungry or cleaning some data so that you can do analysis on the things that we actually need to do to advance our work to make the world a little bit better— the main thing they require is somebody to care enough to do it.”

“In January, Invisible Institute released the data on a tool called the National Police Index, which houses data from over two dozen of POST’s peer agencies around the country. Developed by Invisible Institute, Human Rights Data Analysis Group, and Innocence & Justice Louisiana, the NPI seeks employment history data from state POST agencies to track, among other questions, the issue of so-called “wandering cops” who move from department to department after committing misconduct.”

Eric Sears, a director at the MacArthur Foundation who leads the grantmaker’s Technology in the Public Interest program, worked at Human Rights First and Amnesty International before joining MacArthur, and has been following HRDAG’s work for years. … One of HRDAG’s strengths is the long relationships it maintains with partners around the globe. “HRDAG is notable in that it really develops deep relationships and partnerships and trust with organizations and actors in different parts of the world,” Sears said. “I think they’re unique in the sense that they don’t parachute into a situation and do a project and leave. They tend to stick with organizations and with issues over the long term, and continually help build cases around evidence and documentation to ensure that when the day comes, when accountability is possible, the facts and the evidence are there.”

Patrick Ball, director of research at the Human Rights Data Analysis Group, and a statistician who has conducted similar estimates of violent deaths in conflicts in other regions, said the study was strong and well reasoned. But he cautioned that the authors may have underestimated the amount of uncertainty caused by the ongoing conflict.

The authors used different variations of mathematical models in their calculations, but Dr. Ball said that rather than presenting a single figure — 64,260 deaths — as the estimate, it may have been more appropriate to present the number of deaths as a range from 47,457 to 88,332 deaths, a span that encompasses all of the estimates produced by modeling the overlap among the three lists.

“It’s really hard to do this kind of thing in the middle of a conflict,” Dr. Ball said. “It takes time, and it takes access. I think you could say the range is larger, and that would be plausible.”

“Patrick Ball, a statistician at the US-based Human Rights Data Analysis Group not involved in the research, has used capture-recapture methods to estimate death tolls for conflicts in Guatemala, Kosovo, Peru and Colombia.

Ball told AFP the well-tested technique had been used for centuries and that the researchers had reached “a good estimate” for Gaza.”

“Led by the nonprofit Human Rights Data Analysis Group (HRDAG), the process began with creating a merged dataset of “fully identified victims” to avoid double counting. Only casualties whose complete details were listed — such as their full name, date of death and the governorate they had been killed in — were included on this initial list, explained Megan Price, executive director at HRDAG. If details were missing, the victim could not be confidently cross-checked across the eight organizations’ lists, and so was excluded. This provided HRDAG and the U.N. with a minimum count of individuals whose deaths were fully documented by at least one of the different organizations. … “
