Bold, unfiltered, and uncompromisingly honest, Why Should I Trust You? is a weekly podcast that looks at the breakdown in trust for science and public health. It drops every Thursday, with occasional additional special episodes sprinkled in.
Hosted by Brinda Adhikari, the former executive producer of “The Problem with Jon Stewart” and a former TV news journalist; Tom Johnson, the former executive producer of “The Circus,” and also a former TV news journalist; Dr. Maggie Bartlett, a virologist and assistant research professor at Johns Hopkins Bloomberg School of Public Health; and Dr. Mark Abdelmalek a skin cancer surgeon, a medical journalist and a dermatologist practicing in Philadelphia - each week we try to figure out what is behind this staggering collapse in trust and see if we can rebuild towards trust again.

If a new pandemic struck tomorrow and scientists developed a vaccine in record time, would you take it? In this episode, we hear from a group of friends of the show and newcomers who describe themselves as vaccine-hesitant. Once broadly supportive of vaccines, they explain how their experiences during the pandemic changed their views. From concerns about mRNA technology and the speed of development to public health messaging and mandates, we explore how and why their perspectives changed, and trust was lost. While a large body of scientific research holds that the COVID vaccines were safe and significantly reduced severe illness and death, we examine why that evidence remains unpersuasive to them today, just as it was during the pandemic. Finally, we tackle what that means for their trust in the broader medical and public health community today.Hosts:Brinda AdhikariTom JohnsonMaggie BartlettDr. Mark AbdelmalekGuests:Aaron Everitt, Ft.

Dr. Robert Malone and Dr. Craig Spencer are two influential voices on health in America today, reaching very different audiences. And it's no secret that on many critical issues, they fundamentally disagree. Yet as a deadly Ebola outbreak unfolds in Central Africa, they find themselves agreeing on more than you (or they) might expect. In this episode, the two physicians discuss what allowed the outbreak to spiral, the geopolitical priorities that shape the world's response to outbreaks (too often reacting to crises rather than investing in preparedness), whether the dismantling of parts of America's global health infrastructure played a role, and what America's role should be in supporting global public health going forward. Dr. Malone also opens up about his break with the MAHA movement and its leadership, and where he disagrees with the administration's approach to global public health.Hosts:Brinda AdhikariTom JohnsonDr. Mark AbdelmalekMaggie Bartlett (producer)Guests:Dr. Robert Malone, physician, vaccine researcher.

One year ago, the Trump administration dismantled USAID, America's largest foreign aid agency. The administration argued the agency had become wasteful, ideological, and ineffective. Critics warned the consequences would be measured in lives lost.A year later, what actually happened?We speak with two individuals who know the agency and aid landscape, inside and out: Andrew Natsios, who served as USAID administrator under President George W. Bush, and Jeremy Konyndyk, a senior USAID official under the Obama and Biden administrations.Did the warnings about the human cost of cutting aid come true? What reforms did USAID need but never receive? How much authority should a president have to reshape America's foreign aid? And what does the dismantling of USAID mean for America's role in the world?This is a conversation about the future of U.S. foreign aid, one year after one of the most consequential changes to American foreign policy in generations.Hosts:Brinda AdhikariTom JohnsonMaggie Bartlett (producer)Dr. Mark Abdelmalek (off)Guests:Andrew Natsios, former head of USAID under George W. Bush 2001-2006; author of Guns Are Not Enough: Foreign Aid in the National Interest; teaches at the Bush School of Government at Texas A and M UniversityJeremy Konyndyk, president of Refugees International and a former senior USAID official who served in both the Obama and Biden administrations, leading its response to everything from Ebola to Covid-19.

On the very day the Supreme Court handed a major legal victory to Bayer Monsanto, a ruling backed by the Trump administration but viewed by many in the MAHA movement as a betrayal, two regenerative farmers were invited to the Oval Office.They expected to witness President Trump sign an executive order promoting the kind of farming they've spent decades championing: bringing the natural ecosystem back to the farm, and thus restoring soil health and reducing reliance on pesticides.Instead, they found themselves in the middle of a last-minute policy debate involving President Trump, HHS Secretary Robert F. Kennedy Jr., USDA Secretary Brooke Rollins, and Farm Bureau President Zippy Duvall.What did that moment reveal about the competing pressures on the administration? More broadly, can regenerative agriculture move beyond a niche movement? And how do its advocates respond to critics who argue that today's farming methods work, are proven safe, and that transitioning away from them is impractical?This week, we're joined by regenerative farming pioneers Will Harris and Dr. Jonathan Lundgren to discuss what they witnessed in the Oval Office and whether we are moving closer to a regenerative farming future. Hosts:Brinda AdhikariTom JohnsonMaggie BartlettDr. Mark Abdelmalek (off)Guests:Will Harris, fourth-generation cattleman and the owner of White Oak Pastures in Bluffton, Georgia, He has served as President of the Board of Georgia Organics and as Beef Director for the American Grassfed Association.Dr. Jonathan Lundgren, agro-ecologist and the founder of the Ecdysis Foundation and Blue Dasher Farm in Estelline, South Dakota.

It’s almost Independence Day, and we’re exploring one of the most influential political philosophies in America: libertarianism.In the age of medical freedom and MAHA, libertarian ideas are helping shape debates over vaccines, public health, food regulation, and the role of government. But what exactly is libertarianism? Why has it become so persuasive to so many Americans? And where does today's movement depart from its roots?Our guest is Katherine Mangu-Ward, Editor-in-Chief of Reason magazine, the country's leading libertarian publication.We trace the history of modern libertarianism and its influence on today's politics from marijuana legalization and same-sex marriage to debates over tariffs, war, immigration enforcement, and executive power. We also examine where libertarian principles intersect with, and sometimes clash with, MAHA, asking whether a philosophy centered on individual liberty can support vaccine requirements, pesticide bans, or greater government regulation of the food industry.Hosts:Brinda AdhikariTom JohnsonMaggie Bartlett (off)Dr. Mark Abdelmalek (off)Guest:Katherine Mangu-Ward, editor-in-chief, Reason magazine, widely considered the nation's most famous publication dedicated to libertarian ideas.

Democratic Senator Cory Booker, Representative Chellie Pingree of Maine, MAHA leaders Zen Honeycutt and Kelly Ryerson, and former Congressman Tim Ryan join us to react to one of the Supreme Court's big decisions of the year as the High Court sides with Monsanto regarding glyphosate liability. Our panel today represents a powerful, impassioned, and yes, unusual alliance, given MAHA's union with the Republican Party and President Trump. Today, we hear their reactions to this major ruling.With the Court ruling 7–2 that federal law gives the EPA the final say over pesticide warning labels, thousands of pending lawsuits against Bayer-Monsanto will be impacted, marking a win for the company and the Trump administration, which took its side, as well as a significant moment in the ongoing debate over glyphosate.What does the decision mean for this bipartisan coalition united in support of the legal fight against glyphosate and for a future in which American farms transition away from its use? With MAHA and the Trump administration finding themselves on opposite sides in this case, where does the ruling leave that partnership? And finally, we hear about the formation of a new game plan for the movement opposing this ruling. Hosts:Brinda AdhikariTom JohnsonMaggie Bartlett (producer)Dr. Mark Abdelmalek (off)Guests:Sen. Cory Booker (D-NJ)Zen Honeycutt, MAHA activist, Moms Across AmericaRep. Chellie Pingree (D-ME)Kelly Ryerson, MAHA Activist, Glyphosate Girlformer Rep. Tim Ryan (D-OH)Thanks for listening!

Fighting misinformation is seen as one of the defining challenges of our time. The term itself can be polarizing. And what if we're thinking about it all wrong?In this episode, we speak with researchers Michael Simeone and Kristy Roschke, who recently published a peer-reviewed article in a journal in the Nature portfolio, proposing a new framework for understanding why misinformation spreads. Their central argument is a surprising one: misinformation doesn't spread simply because people are uninformed, uneducated, or unable to distinguish fact from fiction. It spreads because it provides value--a coherent explanation amidst uncertainty and conflicting facts, reinforces identities, strengthens communities, and satisfies emotional and social needs. They also factor in the value misinformation might have for a broader community, a commercial platform, or AI. Rather than asking, "How did people fall for this?", they encourage us to ask a different question: "What is this information doing for them?"The conversation challenges common assumptions about health literacy, fact-checking, and who is susceptible to misinformation (answer: all of us). In an era of algorithms, AI, and increasingly personalized realities, Simeone and Roschke argue that understanding misinformation requires us to look beyond individual biases to examine the broader social and technological systems we all help create.Hosts:Brinda AdhikariTom JohnsonMaggie BartlettDr. Mark AbdelmalekGuests:Michael Simeone, co-lead of the Information Competition Lab at Arizona State University’s School for Complex Adaptive Systems and serves on the senior leadership team for the Global Futures Laboratory’s Decision TheaterKristy Roschke, Associate Research Professor of Communication of Science and Technology; Executive Director of the McGee Applied Research Center for Narrative Studies Vanderbilt UniversitySource:Value and Vulnerability: A Framework for Understanding the Complexity of Misinformation Usehttps://www.nature.com/articles/s44260-026-00079-xThanks for listening!

Dr. Mehmet Oz, the head of the Centers for Medicare & Medicaid Services, is our guest today.He oversees the government programs that provide health coverage to nearly half of all Americans and account for roughly a quarter of federal spending.At this moment of enormous change, what does Dr. Oz see as his mission?Alongside Vice President JD Vance, he has been tasked with rooting out fraud. He argues this effort, along with changes to Medicaid in the One Big Beautiful Act, will strengthen thesafety net and preserve it for the Americans it was intended to serve.However, an official nonpartisan government estimate finds that compared with the previous law, the new law will result in hundreds of billions fewer federal dollars going to Medicaid over the next decade and millions more Americans becoming uninsured. Dr. Oz insists America will spend more on Medicaid, not less. We ask him about that.We'll also dig into a larger question at the heart of this debate: Was the ACA's expansion of Medicaid—which has covered roughly 20 million additional Americans—ultimately a good thing? And finally, we ask Dr. Oz, a renowned heart surgeon whose career was built on medical expertise, what he makes of this moment in America, where trust in experts is falling. Is growing skepticism a healthy correction, or is it taking us somewhere more troubling?Hosts:Brinda AdhikariTom JohnsonDr. Mark AbdelmalekMaggie Bartlett (producer)Khushi Patel (research)Isabella Didie (research)**Recorded at Switch & Board Studios in Washington, DC.Guest: Dr. Mehmet Oz, Administrator for the Centers for Medicare and Medicaid ServicesThanks for listening!

Senator Cory Booker joins us for a conversation about our dire chronic health crisis, the corrosive effects of corporate money in our politics, the power of making healthy food affordable, and our taxpayer-subsidized systems that fuel our chronic disease epidemic. These are issues he's been sounding the alarm on for years. Today, the New Jersey Democrat has a new message for his own party: rather than resist the supporters of MAHA, it's time to stand with them.Long before MAHA, Booker was raising the very concerns now at the heart of the movement. But while much of his party has greeted MAHA with suspicion and hostility, Booker is making a different argument: Democrats should find common ground wherever possible.So where, exactly, does he see common ground with MAHA? Can Democrats work with the movement while fiercely disagreeing on vaccines and other critical issues? And how does he answer critics in his own party who see MAHA not as a health movement but as an extension of MAGA?Today, as he pitches a new coalition: why should MAHA trust him? And why should his own party?Hosts:Brinda AdhikariTom JohnsonMaggie Bartlett (producer)Dr. Mark AbdelmalekGuest:Senator Cory Booker, D-NJNew to us? Check out these three episodes to get a taste!

Today, we're widening our lens to take on AI and trust because just like public health, science, and medicine, AI is becoming a trust minefield. As trust in institutions, experts, and Big Tech continues to erode, AI is arriving with enormous promises and profound uncertainties. (And don't worry—we're not taking our foot off the gas on trust and health. We're just doing more!)AI now has us confronting fundamental questions about winners and losers, promises of medical breakthroughs versus warnings of widespread job displacement, and whether the new technology encourages us to offload difficult thinking or frees us to think more deeply. And right in the middle of all these questions is the generation coming of age at the same time as AI.So, today, we've gathered Gen Zers, high school students, college students, recent graduates, young professionals, and people entering the trades. We discuss the issues surrounding AI, especially its impact on education and work, which are already shaping their lives.How do they see the opportunities and risks of AI? What excites them? What worries them? Ultimately, what kind of future do they want to build and what kind of lives do they want to lead?Hosts:Brinda AdhikariTom JohnsonMaggie BartlettDr. Mark AbdelmalekGuests:Elizabeth FrostKhushi PatelSawyer EverittBryson CravenRotimi KukoyiMatt GeistlerKeren Michelle-AsareRohan LichtMichael D.
