466: Jacob Mchangama | The Free Speech Recession: A Global Decline in Expression

[https://www.armenshirvanian.com/podcast/wp-content/uploads/2026/04/Jacob-Mchangama-1024x1024.webp] In this episode, Armen speaks with legal scholar and free speech advocate Jacob Mchangama about the shifting global landscape of expression. Drawing on his new book The Future of Free Speech, Mchangama outlines a central claim: we are in the middle of a “free speech recession,” where both democratic and authoritarian systems are increasingly restricting speech—often for different reasons, but with converging effects. The conversation traces how early optimism about the internet as a tool for openness has given way to a more controlled and centralized environment. Governments now exert pressure on digital platforms, while large tech companies function as de facto gatekeepers of public discourse. At the same time, authoritarian regimes have adapted technology to strengthen censorship and surveillance, creating a more coordinated global push against open expression. Mchangama highlights the historical foundations of free speech, including post–World War II debates over misinformation and the evolution of U.S. First Amendment doctrine through controversial cases. These examples show how strong protections were often built by defending unpopular speech, with long-term implications for minority rights and democratic resilience. The discussion also explores modern tensions: misinformation vs. overreach, public platforms vs. private control, and the psychological pull toward restricting speech during moments of crisis. Mchangama argues that top-down control—whether through governments or platforms—often produces second-order effects, including suppression of dissent and erosion of trust. Possible paths forward include anti-SLAPP laws to protect critics, decentralized platform models, radical transparency, and emerging tools like crowdsourced fact-checking. Underlying all of these is a broader claim: legal protections depend on a culture that values open expression, even when it is uncomfortable. The episode frames free speech not as an abstract ideal, but as an evolving system shaped by incentives, institutions, and human behavior—one that requires active maintenance to preserve its benefits. Jacob Jomo Danstrøm Mchangama is a Danish lawyer, purported human-rights advocate, and public commentator. He is the founder and director of Justitia, a Copenhagen-based think tank focusing on human rights, freedom of speech, and the rule of law. For six years, he served as chief legal counsel at CEPOS.

465: Michael Gurven | The Seven-Decade Human Lifespan

[https://www.armenshirvanian.com/podcast/wp-content/uploads/2026/04/Michael-Gurven-2-681x1024.jpeg] A conversation with Professor Michael Gurven of UC Santa Barbara on the evolutionary structure of human lifespan and the misconceptions surrounding aging. The central claim of Gurven’s work is that humans were not “designed” for short lives that modern medicine has recently extended. Rather, the capacity to live roughly seven decades has long been part of our species’ biological design, conditional on surviving early-life risks. This reframing shifts the discussion from “why are we living so long now?” to “what has always been possible, and under what conditions?” The discussion develops across three layers: 1. Lifespan vs. Life Expectancy Average life expectancy in the past was low primarily due to early mortality. Once individuals reached adulthood, living into later decades was common, not exceptional. 2. Why Aging Exists Aging is not an adaptive trait but a byproduct of evolutionary tradeoffs: * Early-life advantages outweigh late-life costs * Natural selection weakens with age * Resources are allocated to reproduction over indefinite repair This produces aging as a structural outcome rather than a correctable flaw. 3. Limits of Modern Longevity Thinking Efforts to “cure aging” often focus on individual mechanisms (genes, cells, diseases), but aging operates across integrated biological systems. Eliminating specific diseases does not remove the underlying aging process—only shifts its expression. 4. Function vs. Chronological Age Across cultures, aging is not primarily defined by number of years but by functional decline, based on what one can no longer do. This provides a more grounded model of aging than numerical age categories. 5. Cooperation and Longevity Human lifespan is inseparable from social structure. Cooperation, food sharing, and interdependence are not peripheral, but they are foundational to reaching older ages in the first place. — This episode integrates evolutionary theory, anthropology, and modern health discourse into a single model: aging is not a recent problem to solve, but a long-standing feature of human design with identifiable constraints and tradeoffs. [https://www.armenshirvanian.com/podcast/wp-content/uploads/2026/04/Michael-Gurven-Seven-Decades-687x1024.avif] Professor Michael Gurven is an evolutionary anthropologist whose research connects human lifespan, health, and behavior to our species’ cooperative social structure. He has conducted over two decades of fieldwork with indigenous populations in South America and co-directs the Tsimane’ Health and Life History Project, which examines how environment and lifestyle shape health and aging in subsistence societies. His work applies an evolutionary perspective to modern diseases and focuses on how social and environmental factors, including acculturation and market integration, affect development, aging, and chronic disease risk across the lifespan.

464: Carey Gillam | How Industry Manipulates Science and Regulation

[https://www.armenshirvanian.com/podcast/wp-content/uploads/2026/03/Carey-Gillam-1024x1024.jpg] In this returning conversation, investigative journalist Carey Gillam examines how scientific evidence, corporate incentives, and regulatory systems interact in the modern agrochemical landscape. Drawing on more than three decades of reporting, she traces the evolution of glyphosate from a widely adopted agricultural tool to a focal point of global health debate. The discussion centers on a recurring pattern: how safety narratives are constructed, contested, and institutionalized. Internal documents, litigation discovery, and independent research create parallel streams of evidence, often leading to different conclusions about risk. Gillam describes how companies respond when unfavorable findings emerge, including strategies such as shaping research pipelines, coordinating third-party validators, and managing public perception. A key structural tension emerges between independence and funding. Much of the research required for regulatory approval is financed by the companies themselves, creating inherent incentives that complicate interpretation. Attempts to solve this through independent funding models remain limited, leaving regulators to adjudicate between conflicting bodies of evidence. The conversation extends beyond glyphosate to newer cases such as paraquat and Parkinson’s disease, where similar dynamics appear: early internal awareness, external scientific signals, and legal processes that ultimately surface information not easily accessible through regulatory channels. Courts, rather than agencies, often become the primary mechanism through which internal company records enter public view. More broadly, this episode examines: * How a chemical moves from controversial to “officially safe” * Why industry-linked studies and independent research diverge * The role of regulatory capture and institutional constraints * The emergence of a “playbook” for managing scientific doubt * The declining capacity of media systems to cover complex scientific disputes At a higher level, the discussion is about epistemic structure: how societies decide what counts as reliable knowledge when incentives are misaligned. The result is not a single conclusion, but a framework for evaluating claims, sources, and the systems that produce them. Gillam closes with a practical emphasis: sustained attention, critical thinking, and engagement remain necessary conditions for navigating environments where information is abundant but not uniformly trustworthy.

462: Caleb Scharf | The Biological Imperative of Space Exploration In “The Giant Leap”

[https://www.armenshirvanian.com/podcast/wp-content/uploads/2026/02/Caleb-Scharf.webp] In this episode, Dr. Caleb Scharf returns to the show, where we discuss his book The Giant Leap: Why Space Is the Next Frontier in the Evolution of Life, exploring the intersection of biology, technology, and space exploration. He argues that space travel is not merely a technological endeavor but a biological phenomenon that reflects the evolution of life on Earth. The conversation delves into thermodynamics, the role of abstract thought in enabling space exploration, and the ethical considerations of human expansion into space. Scharf emphasizes the importance of understanding our place in the cosmos and the potential for life to evolve beyond Earth. CONVERSATION MAP Introduction to space exploration and astrobiology The discussion begins with how astrobiology reframes space exploration: not as engineering expansion, but as a biological question about where life can exist and how we would recognize it. The biological perspective on space travel Spaceflight is reconsidered from the standpoint of organisms rather than rockets – what environments bodies require, what constraints biology imposes, and why most of the difficulty of space travel is physiological rather than mechanical. Thermodynamics and the nature of life Living systems are examined as thermodynamic processes: organized structures sustained by continuous energy flow rather than static objects. Entropy and life’s counterforces Life does not violate entropy; it locally resists disorder by exporting it outward. This provides a framework for detecting life elsewhere by identifying energy gradients being actively exploited. The evolution of technology and intelligence Technology is treated as a continuation of evolution – an externalized adaptation system allowing intelligence to modify environments instead of adapting bodies. The role of abstract thought in space exploration Abstract reasoning enables long-horizon planning, making space exploration possible before it is practical. The idea precedes the capability. The challenges of becoming a multi-planet species Colonization is not mainly a transportation problem but a systems problem involving ecosystems, radiation exposure, reproduction, and long-term viability. The future of robotic exploration Robots may be the natural first explorers because machines tolerate environments that biological organisms cannot, changing what “exploration” means. The possibility of machine life on Mars A speculative scenario: self-replicating or adaptive machines could become a new evolutionary lineage, blurring the distinction between biological and technological life. Changing perspectives on exploration Space exploration shifts from heroic travel narratives to questions about information gathering, sensing, and remote presence. Contamination and Earth’s microbial legacy Sending probes risks exporting terrestrial microbes, complicating the search for indigenous life and potentially altering extraterrestrial ecosystems. Ethics of colonization Whether humans should settle other worlds depends on how we value non-Earth life and whether preservation or expansion takes priority. Human society in space Long-term habitation raises social and political questions: governance, isolation, cooperation, and cultural evolution in constrained environments. Technological vs. Darwinian evolution Biological evolution operates slowly through selection, while technological evolution changes environments rapidly; the interaction between the two shapes humanity’s future. Effects of space exploration on Earth Exploration feeds back into terrestrial life through technology, perspective shifts, and changes in how humanity understands its place in the universe. Agriculture vs. rocketry Historically, agriculture transformed civilization more than transportation technologies. The conversation closes by comparing foundational innovations to question whether spaceflight will be similarly transformative.
