New Report Raises Questions Over CPD’s Approach to Missing Persons Cases

In this video, Trina Reynolds-Tyler of Invisible Institute talks about her work with HRDAG on the missing persons project in Chicago and Beneath the Surface.


One Better

The University of Michigan College of Literature, Science and the Arts profiled Patrick Ball in its fall 2016 issue of the alumni magazine. Here’s an excerpt:

Ball believes doing this laborious, difficult work makes the world a more just place because it leads to accountability.

“My part is a specific, narrow piece, which just happens to fit with the skills I have,” he says. “I don’t think that what we do is in any way the best or most important part of human rights activism. Sometimes, we are just a footnote—but we are a really good footnote.”


Data-driven development needs both social and computer scientists

Excerpt:

Data scientists are programmers who ignore probability but like pretty graphs, said Patrick Ball, a statistician and human rights advocate who cofounded the Human Rights Data Analysis Group.

“Data is broken,” Ball said. “Anyone who thinks they’re going to use big data to solve a problem is already on the path to fantasy land.”

Humanitarian Statistics

In late 2006, a statistical study of deaths that occurred after the invasion of Iraq ignited a storm of controversy. This Lancet study estimated that more than 650,000 additional Iraqis died during the invasion than would have at pre-invasion death rates, a vastly higher estimate than any previous. But in January, a World Health Organization study placed the number at about 150,000.

Experts Greet Kosovo Memory Book

On Wednesday, February 4, in Pristina, international experts praised the Humanitarian Law Centre's database on victims of the Kosovo conflict, the Kosovo Memory Book. HRDAG executive director Patrick Ball is quoted in the article that appeared in Balkan Transitional Justice. HLC’s work won praise from Patrick Ball, from Human Rights Data Analysis Group and from Michael Spagat, professor of economics at Royal Holloway, University of London, who have examined and analysed the database. Ball, with 24 years of experience in databases and statistics of human rights, said that the HLC’s database had enormous quality and marked it out as among the ...

Colombia (eng)

Text in English Assessing Claims of Declining Lethal Violence In March 2007, HRDAG published a study entitled "Assessing Claims of Declining Lethal Violence in Colombia." The authors of this report evaluated assertions that violence in Colombia declined after the demobilization of paramilitaries. They showed that these claims rest both on the overinterpretation of unadjusted data and on unsound causal inferences. The authors concluded that multiple data sources are needed to estimate the true rates of violence in Colombia after demobilization and they suggest avenues for further research. This research paper is also available in Spanish at ...

Syria’s status, the migrant crisis and talking to ISIS

In this week’s “Top Picks,” IRIN interviews HRDAG executive director Patrick Ball about giant data sets and whether we can trust them. “No matter how big it is, data on violence is always partial,” he says.


Gaza death toll 40% higher than official number, Lancet study finds

“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.”


Covid-19 Research and Resources

HRDAG is identifying and interpreting the best science we can find to shed light on the global crisis brought on by the novel coronavirus, about which we still know so little. Right now, most of the data on the virus SARS-CoV-2 and Covid-19, the condition caused by the virus, are incomplete and unrepresentative, which means that there is a great deal of uncertainty. But making sense of imperfect datasets is what we do. HRDAG is contributing to a better understanding with explainers, essays, and original research, and we are highlighting trustworthy resources for those who want to dig deeper.
