Robinson's Podcast

Brian Little, a renowned personality psychologist from Cambridge University, dives into the captivating world of the Big Five personality traits. They explore how these traits—openness, conscientiousness, extroversion, agreeableness, and neuroticism—impact our lives and relationships. Brian discusses the measurement of personality, the interplay between genetics and environment, and the concept of personal projects that shape our identities. Listeners will discover how understanding personality can lead to meaningful change and enhance well-being.

Robert Plomin is MRC Research Professor of Behavioral Genetics at King’s College London. He has published over 800 papers, is among the hundred most cited psychologists of the twentieth century, and was appointed Commander of the Order of the British Empire for his research, the best known of which is on twin studies and behavioral genetics. In this episode, Robinson and Robert discuss the distinction between molecular and quantitative genetics, how one researches the question of nature vs nurture, the extent to which genetics determines human behavior, the controversies about these lines of research, and what to expect in the next ten years of behavioral genetics. Robert’s most recent book is Blueprint: How DNA Makes Us Who We Are (MIT, 2018).

Rebecca Goldstein, a philosopher and novelist, discusses atheism, Spinoza, and the meaning of life without God. Topics include her novel, transitioning from Judaism to atheism, arguments against God's existence, and the relevance of Spinoza's philosophy. The conversation touches on morality, physics, consciousness, panpsychism, and the quest for significance in a vast universe.

Ken Olum is Research Professor in the Department of Physics and Astronomy at Tufts University, where he works on exotic physics and topics in cosmology like cosmic strings, gravitational waves, anthropic reasoning, and inflation. In this episode, Robinson and Ken talk all about cosmic strings, which are spindly, hypothesized astronomical objects of intense mass and energy that may have been created in the earliest periods of the universe.

Joseph LeDoux is Henry and Lucy Moses Professor of Science, University Professor, Professor of Neural Science, Professor of Psychiatry, and Professor of Child and Adolescent Psychiatry at New York University, where he works in neuroscience and related areas. Though his career is expansive, one major focus of his research has been emotions in humans and other animals. He is also the frontman of The Amygdaloids. Joseph’s most recent book is The Four Realms of Existence: A New Theory of Being Human (Harvard, 2023). In this episode, Joseph and Robinson discuss psychoanalysis, the nature of biological life, how nervous systems evolved, and the relationship between consciousness and cognition.

Richard Haier, Professor Emeritus in the School of Medicine at the University of California, Irvine, discusses controversies surrounding human intelligence, the origin and value of IQ tests, the relationship between intelligence and brain structure, the accuracy and potential biases of IQ tests, predicting career success with IQ tests, the parieto-frontal integration theory of intelligence, debunking myths about intelligence, the controversy surrounding standardized tests, and group differences in intelligence research.

Sheldon Goldstein is Distinguished Professor of Mathematics at Rutgers University, where he researches mathematical physics, the foundations of quantum mechanics, and Bohmian Mechanics. He is also Board Member of the John Bell Institute for the Foundations of Physics, founded by fellow Robinson’s Podcast multiverse denizen, Tim Maudlin. In this episode, Robinson and Shelly discuss all things Bohmian mechanics, from the origins of pilot wave theory with de Broglie to its chief theoretical innovations and its relationship to philosophy, including some of the main objections to—and strengths of—the theory. Check out Shelly’s book on the subject, Bohmian Mechanics and Quantum Theory: An Appraisal (Springer, 1996).

Michael Graziano, a professor at Princeton University, dives into the intriguing world of consciousness. He discusses his Attention Schema Theory, revealing how our brains model attention to craft our conscious experience. The conversation explores the philosophical versus scientific approaches to understanding consciousness, and Graziano addresses the meta-problem surrounding it. They also touch on AI's relationship with consciousness and the fascinating links between creative expression in science, music, and literature, highlighting how emotions shape these disciplines.

Una Stojnić is an assistant professor in the Department of Philosophy at Princeton University, where she works in the philosophy of language, formal semantics and pragmatics of natural language, and philosophical logic. In this episode, Robinson and Una discuss three of her projects. First, they talk about linguistic conventions, and how language consists of more than just the words we might find in a dictionary. Second, they talk abut slurs and pejoratives, and how philosophers have attempted to determine just what it is that makes them offensive. Finally they talk about a problem with word individuation—just how much can our spelling or pronunciation of a word vary from its canonical spelling or pronunciation and still be that same word? Una’s latest book is Context and Coherence: The Logic and Grammar of Prominence (Oxford, 2021).

David Wallace is Mellon Professor in the Department of History and Philosophy of Science at the University of Pittsburgh. Before that, he obtained PhDs in both physics and philosophy at Oxford. David works mainly in the philosophy of physics, and is best known for his development and defense of the Everett—or Many-Worlds—interpretation of quantum mechanics. In this episode, Robinson and David talk all about Many-Worlds, including its history, how it relates to the broader question of realism in the philosophy of science, its strong points, and some potential problems, such as how to account for probability in the multiverse. David’s book on the subject is The Emergent Multiverse (Oxford, 2014).
