Invisible Institute

Invisible Institute, a Chicago grassroots organization, works closely with HRDAG and relies upon a team of community organizers, human rights experts, and other community members. HRDAG trains the team to read and code extracted allegation descriptions from police misconduct documents in order to give visibility to allegations that would otherwise be lost.

Data science and police accountability

Human bias is baked into criminal justice data, from who gets arrested, to what charges they are booked on, to what happens after they are in custody. HRDAG investigates how these data inform the artificial intelligence that underpins tools used by police and judges. Read more.

Statistics and Covid-19

Most of the available data on the coronavirus pandemic are incomplete and unrepresentative, which creates uncertainty. But HRDAG excels at making sense of imperfect data sets. We identify and interpret the best science, and we provide guidance through original publications. Read more.

Finding Mexico’s hidden graves

For more than ten years, Mexican authorities have been discovering hidden graves. HRDAG creates models to predict the probability of finding a grave in each county, which helps families of the disappeared develop search strategies. Read more.

We are statisticians for human rights
When we partner with human rights defenders, from truth commissions to UN missions to local activists, we help them understand how data science can be used to answer questions about human rights violations. Three directives guide our work:  

Apply science to create new knowledge

Through our publications, statistical analyses, and expert testimony in war crimes trials, we help to establish a rigorously and accurate historical record of human rights abuses.   

Conduct basic research and development

We invent and extend scientific methods so that we can better understand patterns of mass violence, relying on our core concepts to guide us.  

Educate and train the next generation

We help those working in the human rights community to better understand the role and power of statistical data and reasoning. We do this by: training HRDAG interns and fellows in our methods; working closely with partners to teach them data science principles and methods; and through speaking engagements and training sessions for potential partners.   

Inaccurate statistics can damage the credibility of human rights claims—that’s why statistics about human rights violations must be as scientifically accurate as possible.

Working with Partners
