Matrix Podcast

Recorded on March 18, 2025, this video features a talk by Alexander F. Roehrkasse, Assistant Professor of Sociology and Criminology at Butler University. Roehrkasse's research focuses on inequality, victimization, punishment, families and children, and quantitative and historical methods. His work has been published in the American Sociological Review, Demography, Proceedings of the National Academy of Sciences, Science Advances, Social Forces, and other leading journals. He received his Ph.D. in Sociology from UC Berkeley. This talk is part of a symposium series presented by the UC Berkeley Computational Research for Equity in the Legal System Training Program (CRELS), which trains doctoral students representing a variety of degree programs and expertise areas in the social sciences, computer science and statistics. Co-sponsored by the Berkeley Institute of Data Sciences (BIDS). Abstract The dynamics of inequality in mass incarceration are rapidly changing and poorly understood. In this talk, I present new evidence of declining Black–White inequality and skyrocketing educational inequality in U.S. prison admissions. I qualify these findings by documenting vast racial disparities in indirect contact with the carceral system through families and neighborhoods. I conclude by discussing possible causes of recent inequality trends and potential research strategies for identifying them.

Psychedelics are steadily moving from the fringes of counterculture to the heart of mainstream society, driven by a growing body of research and shifting public perception. Once relegated to underground movements, substances like psilocybin, LSD, and MDMA are now being explored for their potential in treating mental health conditions such as depression, PTSD, and anxiety. High-profile studies at institutions like Johns Hopkins and Stanford have highlighted their therapeutic benefits, while cities like Denver and Oakland have decriminalized their use. In addition, psychedelic retreats, wellness practices, and even art and tech industries are embracing these substances as tools for creativity, self-discovery, and healing. As psychedelics shed their stigma, they are catalyzing a broader conversation about mental health, spirituality, and the boundaries of human consciousness. Recorded on March 6, 2025, this panel featured Diana Negrin, Lecturer of Geography at UC Berkeley; David Presti, Professor of Neuroscience at UC Berkeley; Charles Hirschkind, Professor of Anthropology at UC Berkeley; and Graham Pechenik, a patent attorney and founder of Calyx Law. Poulomi Saha, Associate Professor of English and Co-director of the Program in Critical Theory at UC Berkeley, moderated. Matrix On Point is a discussion series promoting focused, cross-disciplinary conversations on today's most pressing issues. Offering opportunities for scholarly exchange and interaction, each Matrix On Point features the perspectives of leading scholars and specialists from different disciplines, followed by an open conversation. This event was co-sponsored by the UC Berkeley Department of Geography, the Program in Critical Theory, Center for Interdisciplinary Critical Inquiry, the Center for Research on Social Change, the UC Berkeley Department of English, and the UC Berkeley Center for the Science of Psychedelics.

One measure of the fragile state of many democracies is the way in which public universities have come under attack around the world. A new podcast series, produced as part of the Global Democracy Commons project, seeks to address the myriad forces seeking to foreclose public universities as spaces of critique and democratic protest across the globe. The series explores diverse trends such as related to the defunding of higher education; its redefinition as a private not a public good; the increasing authoritarian nature of university management; the use of culture wars and discourses of civility to police classrooms; the waves of layoffs and closures of departments and programs; and the attempts to delimit academic freedom, free speech, and rights of assembly and protest. We hope our conversations with those who work in higher education around the world will allow us to consider the degree to which the university has become the canary in the coal mine for the fate of democracy. Episode 3 As universities across England and Wales continue to announce redundancies, close departments and programs we talk to political theorist Lorna Finlayson about the nature of the crisis, why academics are relatively restrained in their responses to it, and how students offer some hope for alternative visions of higher education.

Recorded on February 10, 2025, this "Authors Meet Critics" panel centered on the book Society Despite the State: Reimagining Geographies of Order, by Gerónimo Barrera de la Torre, Assistant Professor of Geography at UC Berkeley, and Anthony Ince, Senior Lecturer (Associate Professor) in Human Geography at Cardiff University and British Academy Mid-Career Fellow. Professor Barrera de la Torre was joined in-person to introduce the book, and Professor Ince presented remotely. The authors were joined in conversation by Dylan John Riley, Professor of Sociology at UC Berkeley, and Anna Stilz, Professor of Political Science at UC Berkeley. Jake Kosek, Associate Professor of Geography at UC Berkeley, moderated. The Social Science Matrix Authors Meet Critics book series features lively discussions about recently published books authored by social scientists at UC Berkeley. For each event, the author discusses the key arguments of their book with fellow scholars. These events are free and open to the public. The panel was co-sponsored by the UC Berkeley Department of Geography, the Charles and Louise Travers Department of Political Science, the UC Berkeley Department of Sociology, and the Center for Interdisciplinary Critical Inquiry. About the Book The logic of the state has come to define social and spatial relations, embedding itself into our understandings of the world and our place in it. Anthony Ince and Gerónimo Barrera de la Torre challenge this logic as the central pivot around which knowledge and life orbit, by exposing its vulnerabilities, contradictions and, crucially, alternatives. "Society Despite the State" disrupts the dominance of state-centred ways of thinking by presenting a radical political geography approach inspired by anarchist thought and practice. The book draws on a broad range of voices that have affinities with Western anarchism but also exceed it. This book challenges radicals and scholars to confront and understand the state through a way of seeing and a set of intellectual tools that the authors call 'post-statism' In de-centring the state's logics and ways of operating, the authors incorporate a variety of threads to identify alternative ways to understand and challenge statism's effects on our political imaginations.

Julia Sizek is a writer and anthropologist who studies the California desert and rural land management more broadly. Her work focuses on the politics of land in the California desert, including: the cultural politics of conservation acquisition in the railroad checkerboard, the rhetoric of environmental impact reporting, and the legal geographies of off-highway vehicle use. In addition to this work, Julia has also led the qualitative portion of the 30-year social and economic monitoring for the Northwest Forest Plan. Previously, Julia was a postdoctoral scholar at Berkeley's Social Science Matrix, running programs, planning events, and interviewing social scientists about their research. Julia also hosted the Matrix Podcast. In this interview, recorded in Spring 2024, Sizek talked with Marion Fourcade, Director of Social Science Matrix, about her paper "Impossible evidence: The legal dismal cycle of regulating off-roading in the California desert," published in Geoforum. The paper traces a 40-year battle over off-road vehicle use in the California desert through the concept of "impossible evidence," evidence that is legally demanded but cannot or does not exist. In a forthcoming summer 2025 article in Environmental History, Julia builds on this story by detailing the rise of the "Bureau of Livestock and Motorcycles" in California.

Fringe politics today is highly diverse and dynamic, reflecting the rapid social, technological, and economic changes of the 21st century. While the term "fringe" suggests ideas or movements outside the political mainstream, many fringe ideologies have increasingly influenced, or even reshaped, national and global political landscapes. Recorded on February 4, 2025, this panel brought together a group of UC Berkeley graduate students from the fields of geography, anthropology, and sociology for a discussion on politics on the fringe through the lens of such topics as QAnon, religious studies, and California secessionism. The panel featured Josefina Valdes Lanas, PhD candidate in Anthropology at UC Berkeley; Alexis Wood, PhD student in Geography at UC Berkeley; and Peter Forberg, PhD student in Sociology at UC Berkeley. Paul Pierson, Professor of Political Science at UC Berkeley, moderated. The event was co-sponsored by the UC Berkeley Department of Geography, the Department of Sociology, the Charles and Louise Travers Department of Political Science at UC Berkeley, the Berkeley Economy and Society Initiative (BESI), and the Berkeley Center for Right-Wing Studies.
