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.

Rice University research shows the importance of coworker and leadership trust within businesses

Houston Voices

While U.S. soldiers battled in Vietnam, inside the White House, President Lyndon Johnson grew increasingly suspicious of those closest to him. The legendary political dealmaker now believed that any opposition to the war was part of a conspiracy against him; aides who questioned his policy might be part of it. According to research using newly available interviews and telephone transcripts, Johnson's distrust may have been triggered by the very experience of being in power.

But how, exactly? In a recent paper, Rice Business professor Marlon Mooijman and a team of colleagues delve deeply into the interaction of power and trust, seeking answers about when and why wielding power degrades leaders' belief in those around them.

The question has deep implications not only in politics, but also in business. "Managers must trust employees' willingness to comply with instructions and keep the company's best interest in mind," Mooijman notes. Without that trust, past research shows, workplace productivity, reciprocity and cooperation break down. Leaders who successfully craft trusting bonds with their coworkers and employees, on the other hand, are more effective than those who don't.

To learn why leaders might abandon that trust, Mooijman's team set up four studies. First, though, they had to establish a working definition of trust. Trust, they proposed, is the willingness to be vulnerable to another party's actions, based on the expectation that the other party will perform a specific action important to the truster — even without the truster's ability to monitor or control the activity. Essential to a trusting relationship: the expectation of the other party's goodwill, and the willingness to expose themselves to possible exploitation if that goodwill fails.

Whether you work in an indie coffee shop or a giant software company, most workers can name a leader who lacks that kind of trust. Many also have had the good luck of a leader who isn't lacking in that department. The difference between such managers, Mooijman's team found, may be the stability of their power.

There are plenty of reasons for wanting to keep power, obviously. In relationships, power holders are able to disregard others' wishes and pursue their own. Within the individual, power boosts self-esteem and encourages behaviors such as expressing amusement and happiness. Less obvious, however, is the effect of fearing a loss of power. Leaders whose power feels unstable experience this physically, with changes in heart rate and blood pressure. They have a heightened awareness of colleagues they perceive as threats, and are more prone to divide coworkers and disrupt their alliances.

When power holders or leaders perceive their power to be unstable, it's that prospect of power loss that erodes their trust in those around them, even helpful and often unsuspecting colleagues. So strong is this effect that it occurs even when the loss of power comes with an economic benefit, Mooijman notes. "Unstable power decreases trust," the team found, "regardless of whether we provided participants with a justification of their unstable position."

To reach their conclusions, Mooijman's team first surveyed 206 participants assembled through Amazon's Mechanical Turk software. Each participant was randomly assigned a power ranking (high or low) and asked to imagine being a VP of sales at a mid-sized firm. Some were told that as part of a productivity initiative they would be reassigned to other divisions. The participants were then asked to rank their perception of their power at their firm and their perception of their job stability there. Regardless of whether their job reassignment was explained or not, the researchers found, the participants who perceived their jobs — that is, their power — to be unstable showed more mistrust of their coworkers.

A final study, a field experiment with real life managers and subordinates, reinforced these findings. Managers in positions of relatively high power who perceived their jobs were unstable were more prone to voice distrust about their subordinates.

While instability is built into political careers, Mooijman's findings have practical implications in other industries. For example, the common practice of moving workers between departments, meant to build insight and productivity, may backfire. Instead of strengthening team spirit, the strategy will likely foment distrust. Similarly, at high levels of power, emphasizing job instability with tactics such as high-stakes, winner-take-all performance metrics might be counterproductive.

Power doesn't always erode trust, the researchers found. Leaders who felt their power was secure didn't show the same level of suspicion as those who felt their roles were insecure. But when power seems fragile, the research revealed, even the most seasoned leaders are prone to abandon trust in their colleagues and see work as a battlefield.

Houston founders launch edtech startup, pilot to pinpoint why students are struggling

learning gaps

Early detection. It sounds simple enough: identify a problem before it has the chance to become a bigger one.

But in practice, early detection is much more difficult to navigate, especially in education, when it comes to identifying the reasons behind a student's academic struggles.

That’s why co-founders Alapati “Al” Ware and Estela Montanez launched Progress Report, a Houston-built K-12 learning-intelligence platform designed to go beyond identifying that a student is struggling.

The platform recently began its pilot program with 35 educators and more than 200 students in Texas and Arizona.

“It’s a micro-learning school that works with children with disabilities, primarily dyslexia and nonverbal students,” Ware tells InnovationMap.

The platform is also being used by homeschool parents, home teachers and Houston educators, including those at SWPS College & Career Preparatory Academy, a Houston charter school.

Ware says Progress Report was designed to fill a gap he and Montanez saw in existing edtech. Some platforms cater almost entirely to students, leaving teachers with little insight into if and how a child is learning. Others focus heavily on district data, where “the student is just a number,” leaving teachers to navigate disconnected tools.

“Our goal was [to] focus purely on the teacher because the teacher is the backbone,” Ware says.

Progress Report traces student performance to learning gaps and prerequisite skills, helping educators understand not only where a student is struggling, but what may be causing it.

The platform then helps teachers build individualized instruction for general education students, students with special education and Individualized Education Program (IEP) needs, and Spanish-speaking learners—all within one educator-controlled system.

The goal is to reduce the guesswork and hours of manual work educators can spend developing individualized lesson plans.

For Ware and Montanez, the mission is also personal.

The concept dates back to around 2023, when the co-founders first had to navigate and address their children’s educational needs.

Ware, Progress Report’s CEO and CTO with a background in edtech, built the platform end-to-end after watching his daughter, who had an IEP related to speech, struggle to get the support she needed.

Montanez, the company’s COO, brought another perspective. Her son is on the autism spectrum. She now leads Progress Report’s operations, partnerships and pilot execution while helping carry its focus on bilingual families from Puerto Rico to Houston.

Together, they began researching ways to personalize their children’s learning and help them progress academically. Montanez’s son went on to become an AP student and high school athlete, while Ware’s daughter began reading more than two grade levels above her grade, they tell InnovationMap.

But Progress Report isn’t designed simply to give a struggling student more work.

Take a student who appears to have difficulty with math.

The problem may not actually be math, the founders share. The student could understand the calculations but struggle to comprehend complex words used in a math problem.

Progress Report is designed to trace those performance patterns back to learning gaps, prerequisite skills or other instructional barriers. From there, it can recommend a next instructional step while leaving the educator in control.

The same concept applies to accommodations.

The system can read IEPs, 504 Plans, Present Levels of Academic Achievement and Functional Performance (PLAAFPs), evaluations and other special education records. Approved IEP goals can then be mapped into the student’s learning graph, while accommodations can carry over into lesson planning and question delivery.

The founders say that approach separates Progress Report from simply adding another artificial intelligence chatbot to a classroom. And still, they believe teachers have to remain at the center.

Teachers, in fact, helped build Progress Report.

The founders began meeting with Houston-area educators months before the pilot. Their feedback helped shape the platform before testing began.

“We’ve been building alongside these educators,” Ware says.

Parents are another piece.

Progress Report can give parents access to their child’s learning record so they can see learning gaps as they develop. Teachers can also see information on work being completed at home when the parent and educator are working together.

After the pilot wraps, Ware and Montanez plan to introduce a $29.99 monthly subscription for homeschool parents, teachers and other educators. They say the price was intentionally kept relatively low to help make the tools more accessible.

They are also exploring ways to work with organizations that could help families who can’t afford the platform.

Moving forward, the goal is considerably bigger.

Over the next five years, Ware and Montanez want Progress Report to become what they describe as a “gold standard” in every state. They know getting there will require building relationships with educators, technology leaders, policymakers and school board members.

For now, they’re starting with a few hundred students and a question that sounds simple but can be remarkably difficult to answer: Why is this student struggling?

If Progress Report works the way its founders envision, teachers and parents will have a clearer answer.

Pioneering cohousing development opens in Houston's historic 2nd Ward

Housing in Hou

An experimental, multi-generational building in the East End is now open and accepting residents. Only 10 of the 33 units remain available at East End Commons, the first project from CoHousing Houston.

Located at 115 Lenox, East End Commons was first conceived in 2017 and is designed to combine the security of home ownership with the community aspect of apartment life, essentially a condominium but with added focus on bringing neighbors together.

Units range from 900-2,000 square feet, offering ample private home space, but with a large Common House area and central courtyard for gatherings, working, and interaction. Large front porches encourage people to spend time outside where they can meet their neighbors, as do extensive foot paths for casual meetings.

"At East End Commons, you know your neighbors before you move in — so you have a network of people and spaces that are immediately there for you," said founding resident Kelli Soika. "We designed for larger shared spaces versus larger personal spaces in order to foster the breakdown of the barriers that lead to loneliness."

Combating loneliness and isolation is certainly necessary. A 2025 survey conducted by the American Psychological Association shows that most Americans feel a sense of societal division and lonely. A loss of "third spaces," where people gather outside the home or work, is a prime factor. East End Commons aims to alleviate some of that disconnectedness.

"I wanted to live in a neighborhood that is imbued with a sense of community above the individual, like we have all experienced in Houston during times of disaster recovery," said Lynn Morstead, one of East End Commons‘ founding residents. "In those instances, such as Hurricane Harvey, we surface from our separateness and come together in new and unexpected ways. With East End Commons, the goal is to translate that notion beyond a set period of time and make it a fixture of everyday life. I call it 'disaster-free neighborliness.'"

East End Commons was designed by Kathleen English of English + Associates. Sustainability is part of the project's design, with amenities such as geothermal heating and cooling exchange HVAC, pre-heated water systems, low-energy use air conditioning and heating, and native landscaping.

Prices for units range from $300,000 to the $900,000s, which can be more than double the home price in the rapidly gentrifying East End. HOA fees not only help maintain communal areas, they also cover shared internet, water, and other communal expenses. Similarly, government of the building is handled democratically via a community board that aims to make decisions by building consensus.

MD Anderson president to retire after nine years, interim successor named

retirement plan

An era is ending at The University of Texas MD Anderson Cancer Center.

On Aug. 26, Dr. Peter WT Pisters announced his plans to retire from his role as president of the comprehensive cancer center. He will work on a smooth transition of leadership with interim president Dr. Jeffrey E. Lee throughout September.

“I first arrived at UT MD Anderson 32 years ago with a passion for doing everything I could to advance our mission to end cancer. Serving as the only faculty member to become president, and now marking nine years in the role, I can say with great pride and gratitude that there is no better place than UT MD Anderson to turn hope into healing for patients and families everywhere,” Pisters said in a news release. “With a timeless strategy, a strong leadership team, unprecedented levels of financial health, and a priceless culture anchored in our deeply held Core Values, now is the right time for me to transition to other opportunities. UT MD Anderson has never been stronger, and its future has never been brighter.”

Pisters assumed the presidency in 2017 and helped launch some of the most cutting-edge new clinics in MD Anderson history. One of those was the James P. Allison Institute, named for the Nobel Laureate scientist who discovered a way to suppress immune response on tumors so that immune cells would attack cancer cells instead. As head of his titular clinic, Allison pioneered several new immunotherapies against cancer.

Pisters also oversaw the creation of the Institute for Data Science in Oncology in 2024, an innovative consortium of scientists dedicated to enhancing single-cell imaging to improve precision in cancer treatments. The institute also brought together teams to use data-driven analytics regarding safety, quality and access.

The UT System Board of Regents praised the leadership and work of Pisters in a statement, wishing him well in the next phase of his career.

“The Board of Regents and I are profoundly grateful to Dr. Pisters for his exceptional presidency over the past nine years and for thoughtfully concluding his service when UT MD Anderson is thriving at its best position of peak performance, strength and impact. We wish him our very best with his retirement and in his next chapter,” Kevin P. Eltife, chairman of the UT System Board of Regents, added in the release.
