Rice University researchers find that tracking social media can predict violent events

Every grade school teacher knows that student conduct can get out of hand, fast, when a group of kids eggs on one individual. Time-outs are a testimony to the power of isolating one 10-year-old from a choir of buddies.

Social media plays a role similar to a gang of hyped-up grade schoolers, providing a community that can express collective disapproval of people or events. When this disapproval has a moral cast ⁠— for example, after a police shooting or the removal of a statue ⁠— the social network's particular characteristics are key predictors about whether that disapproval will turn violent.

There is a word for the way group support of a belief system makes it seem worth fighting for: moralization. Tracking social network activity now makes it possible to measure the chances for an individual belief to become moralized by a group ⁠— a phenomenon known as moral convergence.

In a recent study in Nature, Rice Business professor Marlon Mooijman, then at the Kellogg School of Management, joined a team that analyzed when and how violence erupts in protests. In a series of observation and behavior experiments that mixed psychology, organizational theory and computer science, they accurately predicted how violence is influenced by group discussion of moral views on social media.

The researchers started by studying the number and content of tweets linked to the Baltimore riots in 2015, after the death of Freddie Gray in police custody. The researchers then compared these tweets with the number of arrests in a given time frame, using a methodology developed by Marlon Mooijman and Joe Hoover from the Brain and Creativity Institute at the University of Southern California.

To analyze the tweets responding to Gray's death, they first separated them into two sets: Those with moral commentary and those without moral judgments.

Next, the researchers tracked whether tweets with moral content increased on days with violent protests. Violence was measured using the number of police arrests, which the researchers compared with the specific time frames of moral tweets.

There was no major difference in the overall tweet traffic discussing Freddie Gray's death on days with violent protests and on peaceful days. The number of moralizing tweets, however, clearly correlated with episodes of violent protests, rising to nearly double the moralizing tweets on days with no violence.

This raised a provocative question. Were morally ⁠— based tweets a response to the events of the day ⁠— or were they somehow driving the violence?

To find out, Mooijman and Hoover worked with computer scientists Ying Lin and Jeng Ji of Rensselaer Polytechnic Institute and Morteza Dehghani of the University of Southern California to develop algorithms that could establish mathematical probabilities for the results.

For every single-unit increase in moral tweets over a 4-hour period, the researchers found, there was a .25 corresponding increase in arrests.

The researchers then tried to measure the effect similar moral views ⁠— such as a social media page with self-selected members of a similar political affiliation ⁠— had on violence during protests.

To do so, they set up a second study, which measured participant reactions to the protestors of a far-right rally in Charlottesville, Virginia in 2017. Participants ranked their level of agreement over the morality of protesting the rally.

There was a direct relationship between believing a protest action was moral, the researchers found, and finding violence at that protest acceptable. This relationship held true throughout the study, regardless of political orientation.

The researchers' next goal was to identify the impact of exposure to people of like beliefs. To do this, participants rated their feelings when they were told that most people in the U.S. shared their views. While the intensity of participants' moral views created the potential for violence, the researchers found, violence resulted when only actively validated by others with similar views.

Having one's moral outrage supported by others on social media, the professors concluded, may explain the spike in violence in recent protests.

While respect for privacy remains critical, governments and law enforcement can use the social media trend to pinpoint the moments when moral outrage can turn deadly. Perhaps most importantly, however, the research also suggests practical tactics for calming violent tendencies before they get out of control. To reduce real-life protest violence, they wrote, it's critical that social media sites include a variety of voices. It's another reason, if any were needed, that a bit of judicious exposure to other views is healthy for everyone.

Building Houston

The country's largest climatetech startup incubator has made a strategic new hire.

Lara Cottingham is the new chief of staff for Greentown Labs, a Boston-area company that opened in Houston earlier this year. Cottingham previously served as the city of Houston's chief sustainability officer and the chief of staff for the city's Administration and Regulatory Affairs Department for the past seven years. In her new role, Cottingham will oversee the day-to-day operations and communications for Greentown's CEO Emily Reichert, along with key stakeholder engagements and strategic initiatives for the incubator.

"Lara brings a tremendous wealth of knowledge and experience to our team from her dynamic leadership role at the City of Houston," says Reichert in a news release. "Her breadth of knowledge in sustainability, climate, and the energy transition, and her expertise in regulatory and stakeholder aspects of the energy industry, will be incredibly valuable to our team and community."

Under her leadership at the city of Houston, Cottingham was the chief author of Houston's Climate Action Plan, an initiative aimed at reducing greenhouse gas emissions in Houston, and getting the city to a point where it meets the Paris Agreement goal of carbon neutrality by 2050. Cottingham helped the city move to 100 percent renewable electricity, according to the release, and helped turn a 240-acre landfill into the nation's largest urban solar farm.

"In leading the Climate Action Plan, Lara helped spark Houston's leadership in what has become a global energy transition and was a passionate advocate for climate action in Houston," says Houston Mayor Sylvester Turner in the release. "While she will be missed, this new role will only strengthen our partnership with Greentown. I look forward to working with Emily, Lara, and the Greentown team to meet our climate goals and make Houston the energy capital of the future."

Before her work at the city, Cottingham worked at Hill+Knowlton Strategies' Houston office range of clients across the energy sector. Earlier in her career, she served as communications director for two congressmen in the U.S. House of Representatives. She began her work with the city in 2014.

"In working with Mayor Turner and Climate Mayors across the U.S., I saw how important partnerships are to helping cities decarbonize," says Cottingham in the release. "There is no better partner or place for climate action at work than Greentown Labs. Greentown is 100 percent committed to attracting and nurturing the energy companies of the future and making Houston the energy transition capital of the world. I'm excited to join the team and see how climatetech can help cities reach their climate goals."

Greentown Labs first announced its entrance into the Houston market last summer. The new 40,000-square-foot facility in Midtown across the street from The Ion opened its prototyping and wet lab space, offices, and community gathering areas for about 50 startup companies opened in April. Greentown was founded in 2011 in Somerville, Massachusetts, and has supported more than 400 startups, which have raised more than $1.5 billion in funding.
