November 20, 2025 How porn f*cked our minds | Louise Perry
Expert Louise Perry discusses the idea of sexual disenchantment, the commodification of sex, and the impact of the online porn industry on society.
Should we treat “big porn” in the same way we treat industries like “big tobacco”? Journalist Louise Perry thinks so. In her book, The Case Against the Sexual Revolution, Perry discusses the idea of sexual disenchantment, the commodification of sex, and the impact of the online porn industry on society.
She argues that the multibillion-dollar global industry is qualitatively different from past exposure to porn, as it normalizes extreme content and affects the sexual culture of an entire generation. Perry likens porn to "super stimuli" that tap into the natural drive for reproduction but exaggerate it in a maladaptive way, similar to fast food. She also critiques platforms like OnlyFans, noting that while it may appear to cut out the middleman, the platform itself still profits from sexual exploitation.
Perry expresses concern that despite many people having a robust critique of capitalism in other industries like gambling or junk food, they hesitate to apply the same scrutiny to the porn industry. But that may be changing.

November 20, 2025 The friendship recession | Richard Reeves
Why friendships are becoming rarer in America, explained by author Richard Reeves.
Richard Reeves, a senior fellow at the Brookings Institution, discusses the importance of friendships and the potential “friendship recession.” He notes that loneliness can be as harmful as smoking 15 cigarettes per day, but measuring and quantifying friendships is difficult. According to Reeves, an ideal number of close friends is around three or four.
But alarmingly, 15% of young men today report having no close friends, compared to 3% in the 1990s. The COVID pandemic has further tested friendship networks, with women being the most affected due to their friendships' reliance on physical contact. Other factors likely have contributed to the decline in friendships in the 21st-century U.S., including geographical mobility, parenting demands, workism, and relationship breakdowns.
Reeves emphasizes the importance of acknowledging and nurturing friendships as they don't form spontaneously. Admitting the desire for friends requires vulnerability and openness, which may be difficult for some individuals.

November 19, 2025 How theoretical and experimental physicists clash, fight, and make physics better | Janna Levin
Physicist Janna Levin discusses the boundaries of reality and experimentation.
Theoretical cosmologist Janna Levin discusses the dynamic interplay between theoretical and experimental physics. She highlights how physicists navigate the tension between imaginative theorizing and strict adherence to observed reality — leading to both confining approaches within known laws, and explosive creativity that has transformed our understanding of the Universe.
Levin explores questions about the nature of the cosmos, such as the possibility of multiple universes and the enigma of dark matter. She acknowledges the criticism that theoretical work on unobservable phenomena like the multiverse might not fit traditional scientific criteria, but argues that nature may not conform to human definitions.
Levin emphasizes the significance of experimental discoveries, like dark matter’s indirect detection through gravitational effects, in shaping our understanding. Ultimately, she asserts that scientific exploration challenges societal limitations, reshaping values and perspectives while underscoring the profound impact of gazing into the cosmos.

November 19, 2025 Expand your perception. Change your life. | Dr. Jill Bolte Taylor
Neuroanatomist Dr. Jill Bolte Taylor explains the 4 key ”characters” of the brain, and how understanding each can expand your perception of yourself, and the world, forever.
At age 37, neuroanatomist Dr. Jill Bolte Taylor suffered a stroke that would take her eight years to fully recover from. This is how it changed her understanding of the brain.
In this interview, Dr. Jill draws a map of the human brain, explaining how it is comprised of four distinct modules, each serving a unique role in function and personality. This combination of cognitive and emotional components gives rise to the multidimensional characters within each of us.
Are you looking to be more rational, more creative, more forgiving, or perhaps less rigid in your thinking? Dr. Jill suggests that by becoming aware of the four modules of our brains, we can consciously choose to engage specific parts. This awareness allows us to harness the true power of our brains and shape who we want to become, ultimately fostering less anxiety, more inner peace, and a vastly more purposeful life.
--------------------------
About Dr. Jill Bolte Taylor:
Dr. Jill Bolte Taylor is a Harvard-trained and published neuroscientist. In 1996 she experienced a severe hemorrhage (AVM) in the left hemisphere of her brain causing her to lose the ability to walk, talk, read, write, or recall any of her life. Her memoir, My Stroke of Insight, documenting her experience with stroke and eight-year recovery, spent 63 weeks on the New York Times nonfiction bestseller list and is still routinely the #1 book in the category Stroke in the Amazon marketplace.
Dr. Jill is a dynamic teacher and public speaker who loves educating all age groups, academic levels, as well as corporations and not-for-profit organizations about the beauty of our human brain. She focuses on how we can activate the power of our neuroplasticity to not only recover from neurological trauma, but how we can purposely choose to live a more flexible, resilient, and satisfying life.
In 2008 Dr. Jill gave the first TED talk that ever went viral on the Internet, which now has well over 27.5 million views. Also in 2008, Dr. Jill was chosen as one of Time magazine’s “100 Most Influential People in the World” and was the premiere guest on Oprah Winfrey’s “Soul Series” webcast. Her new book, Whole Brain Living – the Anatomy of Choice and the Four Characters That Drive Our Life is a #1 release on Amazon in categories ranging from Neuroscience to Nervous System Diseases and Stroke.

November 19, 2025 When science becomes ideology | Agustín Fuentes
In today’s information saturated digital landscape, discerning the truth has become an increasingly complex challenge. While many assert that science holds the factual truth, the line between science as a methodology and scientism — which asserts that scientific knowledge is more reliable and valuable than all other forms of knowledge — often blurs. When scientists exceed the boundaries of testable hypotheses, personal belief systems intermingle with empirical evidence, complicating our understanding of truth.
Anthropologist Agustín Fuentes contends that human experiences are inherently messy and influenced by factors like racism, sexism, and historical contexts. He argues that a comprehensive understanding of human biology, history, culture, and evolution demands grappling with these complexities, the intricate dynamics of which often extend beyond the assertions of science.
Fuentes’ vision for the future of scientific practice centers around diversifying voices, experiences, and methodologies. A more diverse group of individuals contributes to a richer understanding of the world, offering different perspectives and insights; no one scientist is the same. Embracing the complexity and messiness of the human experience fosters collaboration, creativity, and a holistic approach to knowledge. After all, science is conducted by humans — complex beings inextricably intertwined with their own biases and cultural narratives.
0:00 Scientism as another belief system
1:23 The problem with reductive science
3:19 More diversity, more complexity

About Agustín Fuentes:
Agustín Fuentes, a Professor of Anthropology at Princeton University, focuses on the biosocial, delving into the entanglement of biological systems with the social and cultural lives of humans, our ancestors, and a few of the other animals with whom humanity shares close relations. Earning his BA/BS in Anthropology and Zoology and his MA and PhD in Anthropology from UC Berkeley, he has conducted research across four continents, multiple species, and two-million years of human history. His current projects include exploring cooperation, creativity, and belief in human evolution, multispecies anthropologies, evolutionary theory and processes, and engaging race and racism. Fuentes’ books include Race, Monogamy, and other lies they told you: busting myths about human nature (U of California), The Creative Spark: how imagination made humans exceptional (Dutton), and Why We Believe: evolution and the human way of being (Yale).
