There's a lot of concern about how bots and algorithms shape our experiences, both online and off. Increasingly, those concerns are focused on our politics. Can bots fuel political polarization? Can algorithms shape political narratives? A recent study seeks to understand the agenda-building capabilities of social bots in a political context, and that is a focus of this episode of Stats and Stories, with Phillip Arceneaux and Josh Anderson. Phillip Arceneaux is an assistant professor of strategic communication in Miami University’s Department of Media, Journalism & Film, where he specializes in political communication, public diplomacy, and public relations. Arceneaux also leads the Diplomacy Lab at Miami University and has consulted on public relations and marketing for organizations such as the Department of State, Naval Academy, and Central Intelligence Agency. Josh Anderson is an assistant professor in the School of Journalism at the University of Arizona, where his work focuses on studying science communication from an ecological perspective. Anderson’s research is situated within agenda-building and social identity scholarship. He’s a mixed-methods researcher who uses survey and experimental methods, interview-based qualitative methods, and computational methods to answer his research questions. Phil and Josh are two of the authors on a paper out with the Journal of Public Relations Research that focuses on the role social bots played in shaping campaign communication during the 2022 Ohio midterms.

During the 2010s, the United States netted just under one million new immigrants each year; between 2022 and 2024, that number was closer to three million. But since the election of Donald Trump, immigration to the U.S. has taken a nosedive, and potentially so has the economic growth of the country. The economic impact of the rise and fall of immigration to the U.S. is a focus of this episode of Stats and Stories, with Tara Watson. Tara Watson is the Director of the Center for Economic Security and Opportunity at the Brookings Institution, where she’s also the John C. and Nancy D. Whitehead Chair of Economic Studies. She is also a research associate of the National Bureau of Economic Research. Watson’s an economist whose work focuses on U.S. social policy, with interests in the safety net, health, and immigration. In 2015, she served as deputy assistant secretary for microeconomic analysis in the U.S. Treasury Department’s Office of Economic Policy. In 2021, she published the book ”The Border Within: The Economics of Immigration in an Age of Fear,” co-authored with journalist Kalee Thompson. Earlier this year, Watson published a report with Brookings on the economic impact of immigrants on the U.S. economy.

When reporters cover mass shootings news outlets often struggle to find ways to cover the event that won’t inspire others to do the same thing. Something similar follows in the wake of a suicide. Journalists don’t always cover suicides in their communities but when they do one of the concerns is whether that coverage might lead to a spike in suicides after the story is out. The media’s influence on the actions of individuals is a chronic concern for researchers in a number of fields and is a focus of this episode of Stats and Stories with guest Joel Greenhouse Joel B. Greenhouse, Ph.D., is Professor of Statistics at Carnegie Mellon University, and Adjunct Professor of Psychiatry and Epidemiology at the University of Pittsburgh. He is an elected Fellow of the American Statistical Association, the American Association for the Advancement of Science, and an elected Member of the International Statistical Institute.

When you think about science’s contribution to society, do you think first about new inventions with an immediate economic benefit? What about scientific advances that deliver enormous societal or environmental benefits—but whose economic value may not be immediate or easily measured? How can these latter advances be evaluated? What is the role of governments in recognizing and promoting these advances? On “Stats + Stories,” co-hosts John Bailer and Rosemary Pennington welcome Baroness Alexandra Freeman, a crossbench member of the United Kingdom House of Lords and principal of Hertford College, Oxford (Oxford University), to discuss how science policy might better reflect the full range of impacts science provides—and the important role science communication plays in making those impacts understood. @RoyalStatisticalSociety

Research suggests that more than half of Americans could benefit from taking a GLP-1 RA medication. The drugs were originally designed to help manage type two diabetes, but in 2024, the Food and Drug Administration approved one GLP-1, Semaglutide, for weight loss. With that approval came a spike in prescriptions for the drugs, and a spike in calls related to GLP-1s to poison control centers. That's the focus of this episode of Stats and Stories with guests Jordan and Robert Miller. Jordan Miller is a post-baccalaureate student, double majoring in statistics and data science and mathematics at UT San Antonio. Robert Miller is a specialist in poison information with the South Texas Poison Center at UT San Antonio.

An entire industry has grown up around nutrition and health. People pushing everything from shakes, to meal kits, to special diets. While some of the claims surrounding such products can be questionable at best, the field of nutrition science is growing. Filled with researchers who are working to truly understand the science of food that is a focus of this episode of Stats and Stories with guest Michelle Cardel. Dr. Cardel is an obesity and nutrition scientist, registered dietitian, the Director of Global Clinical Research & Nutrition at WW International, Inc.

Women regularly hold leadership roles in stats departments at universities and in major statistical organizations, but it wasn't so long ago that women had to fight to be included. At one point, women faculty had to climb through the windows of the faculty club at Berkeley to attend meetings there; the stories of the struggles of women to be accepted in the profession aren't always visible. But one scholar is working to ensure those stories aren't forgotten. That's the focus of this episode of Stats and Stories with guest Amanda Golbeck.  Amanda Golbeck is the Associate Dean for Academic Affairs in the College of Public Health at the University of Arkansas for Medical Sciences, where she's also a professor of biostatistics. Golbeck's known for her work on health numeracy, demography, and human intervention trials, but she's also known for her work on statistical narrative and for the biographies she's written. In 2025, Golbeck published Florence Nightingale David: A Passionate Probabilist, Statistician, Historian, and Leader, and in 2017, Equivalence: Elizabeth L. Scott at Berkeley. In 2016, Golbeck received the Elizabeth L. Scott Award from the Committee of Presidents of Statistical Societies for her outstanding efforts in enhancing the status of women and minorities, fostering new leadership opportunities for women and men, promoting diversity at all levels, and advocating for a more inclusive, open, and supportive atmosphere in the statistical sciences.

Last academic year colleges and universities across the US struggled with whether to mandate COVID vaccinations for their students. While colleges often require vaccines, the political controversy surrounding the COVID shots made adopting a vaccine policy a complicated undertaking. But according to one study, it had a profound impact on the national COVID death toll last fall. That's the focus of this episode of Stats and Stories with guest Riley Acton. Riley Acton is an Assistant Professor of Economics at Miami University, as well as a Research Affiliate at the Institute of Labor Economics (IZA) and the College Crisis Initiative (C2i). She is an applied microeconomist who specializes in labor economics and the economics of education.

Taylor Swift is an entertainment juggernaut. She's become one of the best-selling musical artists of all time, with her Eras tour grossing more than $2 billion. During that tour, Swift surprised her audience each night with costume changes to mark different eras of her career. Now, a couple of researchers have figured out how to predict what costumes Swift would wear, when, and if these outfit colors were related to the sentiment of songs being performed. Predicting the colors of Swift's Eras tour is the focus of this episode of Stats and Stories with guests Marina Ferrari de Aquino Klemm and Charlotte M. Jones-Todd. Marina Ferrari de Aquino Klemm is an associate curator at the Auckland War Memorial Museum. She can be found listening to Taylor Swift while she's on marine expeditions throughout the South Pacific, cataloging museum specimens, or analyzing all sorts of biodiversity data.

It can take decades for an urban community to develop, but a fraction of that time for it to be torn apart. Each year, urban residents are forced out of their homes and out of their communities to make way for gentrification or other kinds of urban development. When these individuals are forced to leave their homes, they're also forced to leave behind their histories and cultures. These changes often rob communities of support systems, which is a focus of this episode of Stats and Stories with guest Dr. Tim Thomas. Dr. Tim Thomas is a professional researcher at the University of California, Berkeley, where he served as research director of the Urban Displacement Project. He also founded and serves as the director of the Eviction Research Network. He recently served as the chief research and data officer at the King County Regional Homeless Authority, where he led efforts to use data-driven strategies to address homelessness. Thomas's research focuses on neighborhood change, housing disparity, and urban displacement. His works informed tenant protection laws across the country, as well as the eviction moratorium during the COVID pandemic.

The World Health Organization defines health equity as a public health concept describing equity of access to health resources for genetic, socio-environmental, and economic determinants of health, varying according to individuals, families, and social or societal groups. Concerns about data equity have surfaced, which may result in many populations, including those in rural areas with disabilities, experiencing homelessness or living in low and middle-income regions of the world, being underrepresented in health data sets. This can lead to biased findings and suboptimal health outcomes for certain subgroups, which is the focus of this episode of Stats+Stories with guest Bhramar Mukherjee. Dr. Bhramar Mukherjee is the inaugural Senior Associate Dean of Public Health Data Science and Data Equity and the Anna M. R. Lauder Professor of Biostatistics, as well as Professor of Epidemiology and of Statistics and Data Science at Yale University. Among her many honors, she was elected to the US National Academy of Medicine in 2022.

A 2010 statistic reports that, on average, there are 29,000 personal bankruptcy filings per week in the US, while another states that, on average, 50,000 pieces of floating plastic per square mile are observed in the Pacific Ocean. How might art be used to convey the magnitude of these statistics, suppose 29,000 credit card images of them were arranged to compose a larger image of a full moon, or 50,000 plastic bag images were used as elements to produce an image of a whale? Would you find yourself drawn to the art, and then deeper into the story that inspired the art? Our episode today considers how art might be used to convey and engage people in considering human impact on the world, or the human experience in it, with guest Chris Jordan. Chris Jordan creates photographic digital images of jarring statistics related to American consumption. Each large-scale image gives visual life to incomprehensible statistics like 320,000 light bulbs, equal to the number of kilowatt hours of electricity wasted in the United States every minute from inefficient residential electricity usage, and 28,000 42-gallon barrels, the amount of oil consumed in the United States every two minutes. Jordan graduated from the University of Texas School of Law and, while interested in art, made his living as a corporate attorney in Seattle.

As you reach the end of a long day with an excess of stress how do you recharge? Have you found that a long stroll in the sun or through the woods can provide this renewal?
