Why Negative Campaign Ads Work: David Schweidel on the Psychology Driving This Election Cycle featured image

Why Negative Campaign Ads Work: David Schweidel on the Psychology Driving This Election Cycle

As the 2026 Senate races heat up, negative campaign ads are once again dominating the airwaves. David Schweidel, Professor of Marketing and the Roberto C. Goizueta Professor in Business Technology at Emory's Goizueta Business School, has researched political advertising for years and is currently tracking the 2026 Senate races. Asked why negative campaigns tend to outperform positive ones, Schweidel points to what sticks with voters: "It's those negative messages. It's those attack messages," often fear- or anger-based, that he says are "more arousing to us" and "tends to move the needle more so than positive advertising." Where an ad comes from matters too. Schweidel's research looks at whether messaging originates from the candidate directly or from third parties like PACs or political parties, and he's found that candidate-sourced messaging tends to be more believable, "coming from a human brand," in his words, rather than an unfamiliar political organization. His current research pushes this further, into how political advertising shapes what AI chatbots tell voters. Schweidel notes that where news coverage and social media once drove poll movement, more voters are now turning to AI chatbots for candidate information. Using Maine Senate candidate Graham Platner as an example, he explains that recent news coverage and online conversation about a candidate gets absorbed by these chatbots, ultimately shaping what's presented to a voter asking about that candidate. For campaigns and advertisers, Schweidel frames this as a new channel to understand, similar to how companies already monitor social media conversation, and predicts political campaigns will start actively tracking how their candidates are portrayed in AI responses, the same way many companies now treat AI presence the way they once treated search engine optimization: "What a lot of companies are trying to come up with now is what is the playbook to do the same thing for AI." Dr. Schweidel is an expert in marketing technology, AI, social media, political marketing, and customer analytics. He holds a PhD in Marketing from the Wharton School of the University of Pennsylvania and is the author of Social Media Intelligence and Profiting from the Data Economy. His research has appeared in the Journal of Marketing, Journal of Marketing Research, Marketing Science, and Management Science, and he has been recognized as a Marketing Science Institute Young Scholar and named to Poets & Quants' "Top 40 Under 40." Dr. Schweidel is available to discuss: Why are negative campaign ads more effective than positive ads? Why do negative emotions drive people to vote, donate, and campaign, more than positive emotions?

Augusta University's Simon Medcalfe on the Real Economics of Hosting the World Cup

With the World Cup underway across the U.S., Canada, and Mexico, Dr. Simon Medcalfe, economist at Augusta University's Hull College of Business, wrote for Augusta Business Daily about why FIFA's headline economic projections for the tournament don't hold up. His piece breaks down why most of the spending tied to hosting the event isn't new activity but rather it's money that would have been spent elsewhere regardless. As Medcalfe put it: "New spending is not created; it is just moved around." Read his full column in Augusta Business Daily :  Dr. Medcalfe is a Professor of Economics and Finance at Augusta University, with research spanning sports economics, community and economic development, and social determinants of health. He holds a PhD in Business/Managerial Economics from Lehigh University. If you're covering the economics of hosting major sporting events, public subsidies for host cities, or the gap between projected and actual tourism impact, Dr. Medcalfe is available for comment.

Expert Insights on the Manhattan High-Rise Structural Concerns featured image

Expert Insights on the Manhattan High-Rise Structural Concerns

The unfolding structural emergency at the former Pfizer headquarters on East 42nd Street in Midtown Manhattan raises urgent questions issues such as load limits, weight redistribution, structural steel, emergency shoring and in general the challenges of converting older office towers into residential buildings. As officials and engineers continue to investigate what happened, the incident points to a larger issue facing many major cities: how safely can older commercial buildings be adapted for new uses, especially when vertical additions, new floor loads and major structural modifications are involved? ExpertFile has a range of structural engineering experts available to help journalists and audiences understand the engineering issues behind this story. Featured Experts Edward Sippel, P.E., Ph.D. Assistant Professor, Milwaukee School of Engineering Edward Sippel is an expert in structural engineering at the Milwaukee School of Engineering with a focus on steel structures, stability and structural analysis. His expertise in structural steel, finite element analysis and nonlinear analysis makes him especially relevant to questions about column buckling, steel-frame behavior, temporary reinforcement and how engineers assess whether a damaged steel structure can be stabilized or repaired. David O. Prevatt Professor, University of Florida David O. Prevatt is a structural engineer at the University of Florida whose areas of expertise include structural load paths, structural engineering and resilient building performance. His expertise is especially relevant to explaining how loads move through a building, what happens when weight is added or redistributed, and why engineers must understand the full path that gravity loads take from upper floors down to the foundation. Key Questions Experts Can Address How do added floors or major renovations change the way weight moves through an existing building? What causes a steel column to buckle, and how is that different from other types of structural failure? Why do transition points between older and newer parts of a structure require special attention? How do engineers use temporary shoring, jacks and steel reinforcement to stop movement during an emergency? What should cities, developers and regulators consider as office-to-residential conversions become more common? Additional Structural Engineering Experts Available Beyond load paths and steel mechanics, this story also raises broader questions about structural health monitoring, building inspections, retrofits, aging infrastructure, concrete systems, structural dynamics and resilient design. ExpertFile includes additional experts who can speak to these related issues, including: For journalists covering the Manhattan high-rise situation, office-to-residential conversions, emergency building stabilization or the future of urban infrastructure, these experts offer relevant structural engineering expertise that may help add context, clarity and perspective to your reporting.

The Final Whistle: What Ronaldo’s World Cup
Exit Reveals About Letting Go featured image

The Final Whistle: What Ronaldo’s World Cup Exit Reveals About Letting Go

While the fans watched the final moments of Cristiano Ronaldo’s World Cup career, they were also witnessing something much deeper than the end of a match. They were seeing the psychological transition that every athlete eventually faces. Elite athletes spend decades developing an identity centered around training, competing, and performing at the highest level. When that chapter comes to an end, the challenge is no longer physical — it becomes psychological. It isn’t about walking away from the sport. It’s about redefining who they are without the game that has shaped so much of their life, and answering the question: who am I without sport? From a sport psychology perspective, successful retirement is defined by how well an athlete adapts to life after sport. Research shows that retirement is healthier when it is done proactively. Ideally, the athlete begins to develop interests outside of sport, builds a strong support system, and recognizes that their value extends beyond athletic performance. The goal is not to replace the identity of the “athlete” but to expand it. The skills that made them successful — discipline, leadership, and resilience — become the foundation for the next chapter. Retirement from elite sport is a process, not a single moment. For someone like Ronaldo, what makes this transition especially unique is that it happened on the world’s biggest stage. Elite athletes transition as millions watch, analyze every reaction, and say goodbye alongside them. It’s completely normal for athletes to experience mixed emotions— pride, gratitude, sadness, uncertainty, and even relief — all at the same time, as they reflect on the reality of closing a chapter that has defined much of their life. The end of an athlete’s elite career isn’t just about leaving competition. It’s about navigating a new sense of identity, discovering purpose beyond sport, and embracing a legacy that has impacted the sport and inspired generations.

North Atlantic Sargassum Bloom Hits Record Levels – and Florida is Feeling the Surge, One Expert Says featured image

North Atlantic Sargassum Bloom Hits Record Levels – and Florida is Feeling the Surge, One Expert Says

Dr. Brian LaPointe, Research Professor at Florida Atlantic University’s Harbor Branch Oceanographic Institute, is one of the nation’s most recognized experts on marine ecosystems. His work spans algal physiology, biochemistry, biodiversity, and coastal conservation — with more than a decade of dedicated research focused on the rise and impact of sargassum blooms across the Atlantic. LaPointe confirmed that sargassum levels in the North Atlantic have hit a new biomass record — and much of it is now washing ashore across South Florida’s coastlines. The scale of this bloom, he says, could have lasting consequences for marine ecosystems, tourism, and public health. LaPointe recently spoke to CNN about why this record bloom is raising alarm bells: “Sargassum goes from being a very beneficial resource of the North Atlantic to becoming what we refer to as… a harmful algal bloom when it comes ashore in excessive biomass.” Ammonia is another problem emitted by the decaying seaweed, LaPointe noted. The chemical compound “strips the oxygen out of the waters along our coastal ecosystems like mangroves, coral reefs, seagrass beds,” he said. The scale of the bloom is staggering. According to University of South Florida estimates cited by LaPointe, over 31 million tons of sargassum have been detected this year — a 40% increase over the previous record.

Can Music Legends Rewrite Their Legacy? featured image

Can Music Legends Rewrite Their Legacy?

The Stones didn’t need another hit. With six decades of chart-topping albums, sold-out tours, and songs woven into popular culture, their place in rock history has long been secure. Yet the band’s scheduled release of another studio album, “Foreign Tongues,” on July 10, raises questions about how late-stage work can impact the legacy of the Stones and other enduring musical acts. For John Covach, director of the Institute of Popular Music at the Univeristy of Rochester and a leading scholar of rock music, that’s where the real story is.  “Every late-career album asks us two questions,” Covach says. “What does it say about where the artist is now? And does it change how we hear everything that came before?” It’s a question that could be applied to artists from Bob Dylan and Paul McCartney to Bruce Springsteen and Neil Young. Sometimes late work reflects an unexpected creative renaissance. Sometimes it simply reinforces an artist’s legacy. Sometimes it challenges audiences to rethink musicians they thought they already understood. Sometimes it becomes a footnote to their career. “An artist's latest act can in many ways be as revealing as their first,” Covach says. Covach, who co-edited The Cambridge Companion to the Rolling Stones (Cambridge University Press 2019) and whose online course on the music of the Rolling Stones has enrolled thousands of students worldwide, says reporters covering the Stones’ new album have an opportunity to explore broader issues that resonate across popular culture: • Can new work meaningfully change an artist’s historical legacy? • Why do some musicians continue creating well into their seventies and eighties while others stop? • Can a new release introduce younger listeners to artists whose biggest hits predate them by decades? • How do critics — and fans — judge new music from legendary performers differently than music by younger artists? • What determines whether late-career work becomes an essential part of an artist's catalog — or a historical footnote? Covach has spent decades studying the evolution of popular music, and his books and scholarship have helped shape how the genre is taught. He is also a frequent media commentator on the cultural significance of major artists and musical milestones. Click on his profile to connect with him.

The Biological Clock Nobody Talks About featured image

The Biological Clock Nobody Talks About

Biology is ageist. There. I said it. Young people have a biological clock that ticks toward new life. It is loud and urgent, and it comes with its own well-funded industry of apps, doctors, and anxious dinner-party conversations. Ours ticks too, but more quietly. Less “the nursery won’t paint itself” and more “the knees are filing a formal complaint.” Same clock. Wildly different countdown. Young people race toward a beginning. We are racing toward… what, exactly? That is the part nobody warned us about in the brochure. I have been thinking about this clock a great deal lately, not in the abstract, philosophical, this-would-make-a-good-dinner-party-topic way. In the personal, slightly unsettling, why-am-I-like-this way. Because somewhere between turning seventy and watching my brother nearly run out of time entirely, I started to suspect that the clock is not just ticking quietly in the background of my life. It may be driving much of my behaviour, and not always in directions I am proud of. At seventy, I have become mildly obsessed with squeezing every drop out of life. Partly because of the birthday. Partly because 33-year-old entrepreneur Steven Bartlett recently declared that a couple of glasses of wine can derail several days of optimal living, causing poor sleep, missed workouts, reduced productivity, and full-scale biological chaos. The internet, predictably, exploded. One side applauded his discipline. The other suggested he put down the smartwatch and pick up a personality (Bartlett, 2025). Then broadcaster Greg James offered a counterpoint worth sitting with maybe measuring every step, calorie, and heartbeat is not making us happier. Maybe it is making us anxious (James, 2025). Let that idea marinate. It hit me harder than I expected. If I call balls and strikes here, I may have become a card-carrying member of Team Optimize. I teach fitness classes. I went back to school. I write books. I hike mountains. I track protein. I have voluntarily reached the age when discussing fibre intake is considered a contribution to the dinner conversation. Normal retirement behaviour, said no one ever. Apparently, I have a track record with this sort of thing. I have written before about my addiction to home improvement, the kind that finds a project the house did not actually need. Self-improvement, I am beginning to suspect, is the same compulsion wearing a different outfit. What I am exploring here is whether I am actually growing, or, as I am increasingly suspecting, just optimizing out of panic. So, I started asking myself an uncomfortable question, one that keeps circling back to that same clock. Am I pursuing excellence, or am I negotiating with my biological clock? Researchers studying aging have found something fascinating about how that clock changes us. As people become increasingly aware that time is finite, their priorities shift: less interested in accumulating and more interested in meaning, less interested in status and more interested in relationships, and less interested in “someday” and more interested in today. Psychologist Laura Carstensen’s landmark work on socioemotional selectivity theory suggests that it is not age itself that changes us. Rather, it is our perception of the time we have remaining (Carstensen, 2006; Carstensen et al., 1999). I am not sure I have made that shift. Not fully. If I am honest, I wonder whether all the doing, the relentless forward motion, is less about passion and more about outrunning something. Maybe I think that if I keep running, Father Time will not catch me. I can smell a fool’s errand a mile away, and yet here I am, lacing up my shoes … possibly while listening to a podcast on slowing down. I have a theory about this. I call it FORO, the Fear of Running Out. Most people assume it means Fear of Running Out of money, and money is certainly part of it. But lately I think money is just the socially acceptable thing we admit to worrying about. The less acceptable version is the fear of running out of time, energy, relevance, and chances to matter. FORO does not always show up as worry. Sometimes it shows up as motion. Another course. Another project. A new certification nobody asked for. A calendar so full it functions less as a planning tool and more as an alibi. If I cannot stop the running out, I can at least look busy while it happens. That is not ambition. That is panic, wearing a blazer and carrying a planner. Then something happened that stopped the clock cold … or at least kept me from ignoring it. Recently, one of my brothers suffered a massive heart attack. One moment, life was proceeding as planned. Next, he was in intensive care fighting for his life. Thankfully, he survived a quadruple bypass and is now on the long road to recovery. I am still processing it. Watching someone you love close to the edge clarifies things faster than any amount of journaling ever has. Suddenly, nobody is talking about productivity hacks or sleep scores. The conversation gets very simple. More time. More laughter. More family dinners. More life. His clock nearly ran out. Mine, presumably, has not. The question is what I plan to do with the difference. And I sat with that, quietly, for a while. Because his heart attack did not just scare me. It held up a mirror. If the people who matter most to me were sitting across the table right now, would they say I have been present, or would they say I have been busy? I am not sure I want to hear the answer. But I think I already know it, because my wife Bonnie and my dog Dottie have been telling me for a while now, in their own ways. Bonnie has not complained, not really, though I have noticed the particular quiet of someone who has learned not to wait up and has become quite good at saving me half a plate of dinner without asking what kept me. That quiet has nothing to do with her and everything to do with me. Dottie has taken a more direct approach. She has started leaving passive-aggressive stuffed toys outside my office door, which I choose to interpret as a formal grievance filed by a ten-pound dog with excellent comic timing. Both have been waiting for me while I try to sort this out. But patience, like biology, has its limits. Here is where I have landed, at least for now. Retirement, at its best, should be a contact sport: full-bodied, fully engaged, leaning into life with both hands. But there is a trade-off in the pursuit of optimization that no one puts on the inspirational poster. By filling every available hour with the next worthy initiative, I risk alienating the very people for whom “more life” was supposed to be. That is not ambition. That is a quietly self-sabotaging way of running out the clock on the wrong things. I do not have a tidy resolution. Maybe it means resisting the urge to add more simply because I can. What I keep coming back to is this: presence, being genuinely and unhurriedly present with the people I love, might be the optimization I have been overlooking all along. Not because it is hard to measure, but because it is hard to schedule, and even harder to admit I have been avoiding it. What I want, at the end of the day, is to be as present as humanly possible. Not present in the mindfulness app, remember-to-breathe sense. Actually present. Available. Unhurried. With Bonnie. With Dottie. With the people who have been waiting for me to look up. I am not going to pretend I have made this shift. I have not. But I have started doing something that feels different from doing nothing while thinking deeply about it, and I will take the small win. I dropped one school course this term. I have started leaving my phone in another room during dinner, which Dottie has not noticed, but Bonnie absolutely has. I am trying to ask myself, before I say yes to the next worthy thing, whether I want it or whether some part of me is still trying to outrun a clock that cannot be outrun. Some days I catch myself in time. Other days I sign up for the nine-week certificate anyway and figure it out later. Progress, not perfection. If you are reading this and recognize yourself, or someone you love, the invitation is not to overhaul your entire life by Tuesday, or to ask them to. It is to ask the same question I am still learning to ask. The next time your calendar fills with another worthy thing, pause and ask who benefits from that time. If the honest answer is mostly you, and mostly in a way that keeps you safely too busy to sit still with the people who love you, that might be worth a second look. Not guilt. Just a look. Which brings me back to the clock, because it always does. The biological clock of aging is not warning us that time is running out. It is reminding us that time is valuable, and that the people keeping time with us deserve more of it than the leftovers. Young people hear the clock and ask, “When should I start?” Older people hear the clock and ask, “What am I waiting for?” I think I finally know the answer. It is not another course. It is not another goal. It is them. Turns out the clock was never my enemy. It has been my alarm, going off for months while I kept hitting snooze and signing up for another nine-week certificate instead. The good news is I have finally found a project worth finishing. The bad news is it does not come with a certificate of completion, only my loved ones and whatever time the clock decides to give me to enjoy them. Biology may be ageist, but it is also, infuriatingly, right. Sue Don’t Retire…ReWire!
