Symptoms of Violence

How technology can help spot civil unrest and even war before they start.

In looking for potential geopolitical hot spots, researchers also watch out for many of the broken‑window signals that play a role in neighborhood predictive policing, but on a global scale. The number of cars in hospital parking lots in a major city can suggest an emerging health crisis, as can a sudden jump in school absences. Even brush clearing or road building can predict an event of geopolitical consequence.

Spend enough time on Google Maps and you can even spot a war in the making.

Between January and April 2011, a group of Harvard researchers with the George Clooney–funded Satellite Sentinel Project (SSP) used publicly available satellite images to effectively predict that the Sudanese Armed Forces (SAF) were going to stage a military invasion of the disputed area of Abyei within the coming months. The giveaway wasn’t tank or troop buildup on the border. Sudan began building wider, less flood‑prone roads toward the target, the kind you would use to transport big equipment such as oil tankers. But there was no oil near where the SAF was working. “These roads indicated the intent to deploy armored units and other heavy vehicles south towards Abyei during the rainy season,” SSP researchers wrote in their final report on the incident. True to their prediction, the SAF began burning border villages in March and initiated a formal invasion on May 19 of that year.


Correctly forecasting a military invasion in Africa used to be the sort of thing only a superpower could do; now it’s a semester project for Harvard students.

Much of this data is hiding in plain sight, in reports already written and filed. In 2012 a group of British researchers applied a statistical model to the diaries and dispatches of soldiers in Afghanistan, obtained through the WikiLeaks project. They created a formula to predict future violence levels based on how troops described their firefights in their diaries. The model correctly (though retroactively) predicted an uptick in violence in 2010.


Simple news reports when observed on a massive scale can reveal information that isn’t explicit in any single news item. As I originally wrote for the Futurist magazine, a researcher named Kalev Leetaru was able to retroactively pinpoint the location of Osama Bin Laden within a 124-mile radius of Abbottabad, Pakistan, where the terrorist leader was eventually found. He found that almost half of the news reports mentioning Bin Laden included the words “Islamabad” and “Peshawar,” two key cities in northern Pakistan. While only one news report mentioned Abbottabad (in the context of a terrorist player who had been captured there), Abbottabad is located easily within 124 miles of the two key cities. In a separate attempt to predict geopolitical events from news reports, Leetaru also used a 30‑year archive of global news put through a learning algorithm to detect “tone” in the news stories (the number of negatively charged words versus positively charged words) along 1,500 dimensions and ran the model on Nautilus, a large shared‑memory supercomputer capable of running more than 8.2 trillion floating-point operations per second. Leetaru’s model also retroactively predicted the social uprisings in Egypt, Tunisia, and Libya.

News reports, tweets, and media tone are correlated with violence. Predicting the actual cause of violence is more difficult. Yet researchers are making progress here as well. In Libya, Tunisia, and Egypt, the price of food, as measured by the food price index of the Food and Agriculture Organization of the United Nations, clearly plays a critical role in civil unrest, according to a 2011 paper by Marco Lagi, Karla Z. Bertrand and Yaneer Bar-Yam of the New England Complex Systems Institute. In 2008 an advance in this index of more than 60 base points easily preceded a number of low intensity “food riots.” Prices collapsed and then bounced back just before the 2011 Arab Spring events in Tunisia, Libya, and Egypt. Today, that same rapid inflation in food prices is playing a key role in uprisings in Ukraine and especially Venezuela, where inflation was 56 percent last year.

If you’re a humanitarian nongovernmental organization, knowing where and when civil unrest is going to strike can help you position relief resources and staff in advance. If you’re a company, you can pull your business interests out of a country where the shit’s about to hit the fan. But to law enforcement, predicting the time and place of an event of significance is less important than knowing who will be involved.

Unlike predicting an invasion, piecing together a model of what a particular individual will do involves a lot more variables. Not only is it more challenging technically, it’s also more costly. Researchers can’t just run lab experiments on who will or won’t commit a crime, so research has to take place in the real world. But experimentation here runs up against privacy concerns. In recent years researchers have found a clever way around these thorny issues by looking toward captive audiences, individuals in situations who have effectively relinquished any expectation of privacy.
