  • #27 — Is Willpower Like Muscle Power? with Roy F. Baumeister

    #27 — Is Willpower Like Muscle Power? with Roy F. Baumeister
    Mar 27 2023

    How do we regulate our impulsive emotions, resist temptation, break bad habits, and come up to our best potential - and why do we sometimes run short? Is willpower anything like muscle power?

    In this episode, we welcome prominent social psychologist Roy F. Baumeister, who has published some 700 scientific works, including 40 books. A recipient of many awards, in 2013 Roy received the highest award given by the Association for Psychological Science, the William James Fellow award, in recognition of his lifetime achievements.

    Roy has studied major aspects of the self, the pros and cons of self-esteem, and why it is so hard to do mentally effortful tasks, like studying long hours for a math exam. He is especially known for his work on willpower, self-control, ego depletion, and the dark side of self esteem — how these factors relate to human morality and life success, and can even trigger interpersonal violence.

  • #26 — Smell, Taste & Consciousness with Dr. Stuart Firestein

    #26 — Smell, Taste & Consciousness with Dr. Stuart Firestein
    Feb 2 2023

    Neurobiologist Stuart Firestein, one of the world's leading experts on olfaction, joins Bernard Baars to discuss the similarities and surprising differences of smell and taste in relation to vision, hearing and somatosensory systems, like touch. The olfactory system presents us with alternative views of how sensory stimuli are parsed in the brain and how we integrate those into some sort of conscious worldview.

    Dr. Stuart Firestein specializes in the olfactory system ⎯ why and how our brains and noses sense smell. Stuart is the former chair of Columbia University's Department of Biological Sciences and a neurobiology professor, where his laboratory studies the vertebrate olfactory system, possibly the best chemical detector on the face of the planet.

    Stuart is devoted to the history, evolution, and future of science. Author of "Ignorance: How it Drives Science" and "Failure: Why Science is so Successful” (OUP), his books cast science as an unending quest to illuminate ignorance and failure as an essential component in that process.

  • #25 — Human Consciousness and AI: What Does the Future Hold? with Susan Schneider and Rachel St. Clair

    #25 — Human Consciousness and AI: What Does the Future Hold? with Susan Schneider and Rachel St. Clair
    Jan 2 2023
    In this episode, we examine Human Consciousness and AI, and particularly the popular idea that AI will become conscious at some point. Because conscious brains are the product of enormous periods of evolution and environmental conditions that keep changing in basic ways, the popular idea that machine consciousness is just around the corner is questioned by Bernard Baars. But very important ethical and practical questions are already emerging today. Social media has trouble distinguishing between human messages and bots, and we are already seeing AI being used in armed drones in a major European war in the Ukraine. All kinds of important ethical and practical questions are already facing the world. In some ways, this is like the early days of nuclear weapons - people around the world are wondering what the new technologies will bring. What does the future hold? AI technology is developing faster than most of us expected. The worldwide web has triggered a great information explosion that continues in wave after wave. Historically, information explosions are often very disruptive, as in the rise of the printing press, of radio and television, and now the spread of intelligent computers. Human beings need time to adjust to fast changes. So today, we will discuss the future of Artificial Intelligence in relation to human consciousness, including major ethical questions raised by philosophers and others. We also discuss some of the latest promising, and positive, scientific advances in AI. Our special guest is Dr. Susan Schneider, Founding Director of the Center for the Future Mind at Florida Atlantic University, where she also holds the William F. Dietrich Distinguished Professorship. She is co-director of the MPCR Lab at FAU’s new Gruber Sandbox, a large facility which builds AI systems drawing from neuroscience research and philosophical developments. Susan recently completed a three year project with NASA on the future of intelligence. She now works with the United States Congress on AI policy. Susan is also an author, and her current book “Artificial You'' discusses the philosophical implications of AI, and, in particular, the enterprise of “mind design.” Also joining us today is postdoctoral fellow Rachel St. Clair, the founder and CEO of Simuli Inc., whose passion and goal is to help build beneficial AGI.
