Carl Bergstrom, a researcher studying information and disinformation in biology, joins the podcast to discuss the prevalence of bullshit in our world. He explores the flow of information in social networks, especially during the COVID-19 pandemic. They explore topics such as the challenges of misinformation on social media, the impact of data on persuasive arguments, and the divisive response to the pandemic. Bergstrom also discusses the importance of media literacy and regulating social media algorithms.

Despite occasional and important disagreements, most people are in rough agreement about what it means to be moral, to do the right thing. There’s much less agreement about why we should be moral, or even what kind of answer to that question could be convincing. Philosopher Russ Shafer-Landau is one of the leading proponents of moral realism — the view that objective moral truths exist independently of human choices. That’s not my own view, but ethics and meta-ethics are areas in which I think it’s wise to keep an open mind and listen to smart people who disagree. This conversation offers food for thought for people on either side of this debate.Support Mindscape on Patreon.Russ Shafer-Landau received his Ph.D. in philosophy from the University of Arizona. He is currently Professor of Philosophy at the University of Wisconsin-Madison.

Astrobiologist Stuart Bartlett discusses a new framework for defining life based on dissipation, autocatalysis, homeostasis, and learning. The importance of defining life for scientific understanding, complexity saturation in artificial life, overcoming cooperation barriers, and the role of auto-catalysis in regulating multicellular organisms are also explored.

We gather empirical evidence about the nature of the world through our senses, and use that evidence to construct an image of the world in our minds. But not all senses are created equal; in practice, we tend to privilege vision, with hearing perhaps a close second. Ann-Sophie Barwich wants to argue that we should take smell more seriously, and that doing so will give us new insights into how the brain works. As a working philosopher and neuroscientist, she shares a wealth of fascinating information about how smell works, how it shapes the way we think, and what it all means for questions of free will and rationality.Support Mindscape on Patreon.Ann-Sophie Barwich received her Ph.D. in Philosophy at the Centre for the Study of the Life Sciences, University of Exeter.

Creativity is one of those things that we all admire but struggle to define or make concrete. Music provides a useful laboratory in which to examine what creativity is all about — how do people become creative, what is happening in their brains during the creative process, and what kinds of creativity does the audience actually enjoy? David Rosen and Scott Miles are both neuroscientists and musicians who have been investigating this question from the perspective of both listeners and performers. They have been performing neuroscientific experiments to understand how the brain becomes creative, and founded Secret Chord Laboratories to develop software that will predict what kinds of music people will like.Support Mindscape on Patreon.David S. Rosen received his Ph.D. in cognitive psychology from Drexel University. He is currently a co-founder and the chief operations officer at Secret Chord Laboratories, a music-tech startup company. His interdisciplinary research program covers an array of topics: creative cognition, peak experiences, the neuroscience of music production and perception, psychedelics and STEAM education. David began playing the piano at the age of 8 and bass at age 15. He is the co-creator and bassist of sci-fi transmedia band, Chronicles of Sound, and instrumental progressive rock band, NAKAMA.Scott Miles received his Ph.D. in neuroscience from Georgetown University. He is currently the CEO and innovation leader of Secret Chord Laboratories. He has been performing and producing music since the age of 10. In his doctoral work he investigated how music preference is formed in the brain. He secured funding through the National Science Foundation Graduate Research Fellowship to support this work. With David Rosen, Ph.D., he found support for two hypotheses about how the structure of music leads to purchase decisions. Miles then coded an algorithm to generate new music, and in a behavioral experiment, music featuring these properties was indeed preferred. He formed and has overseen the development of Secret Chord laboratories since it was incorporated in June 2018.Secret Chord LaboratoriesPaper on Surprise and MusicSee Privacy Policy at https://art19.com/privacy and California Privacy Notice at https://art19.com/privacy#do-not-sell-my-info.

Cooking is art, but it’s also very much science — mostly chemistry, but with important contributions from physics and biology. (Almost like a well-balanced recipe…) And I can’t think of anyone better to talk to about the intersection of these fields than Kenji López-Alt: professional chef and restauranteur, MIT graduate, and author of The Food Lab. We discuss how modern scientific ideas can improve your cooking, and more importantly, how to bring a scientific approach to cooking anything at all. Then we also get into the cultural and personal resonance of food, and offer a few practical tips.Support Mindscape on Patreon.James Kenji López-Alt received a bachelor’s degree in architecture from MIT. After working at several restaurants, he began writing the Food Lab column for Serious Eats, where he is now Chief Culinary Consultant.

The best chess and Go players in the world aren’t human beings any more; they’re artificially-intelligent computer programs. But the best poker players are still humans. Poker is a laboratory for understanding how rationality works in real-world situations: it features stochastic events, incomplete information, Bayesian updating, game theory, reading other people, a battle between emotions and reason, and real-world stakes. Maria Konnikova started in psychology, turned to writing, and then took up professional-level poker, and has learned a lot along the way about the challenges of being rational. We talk about what games like poker can teach us about thinking and human psychology.Support Mindscape on Patreon.Maria Konnikova received her Ph.D. in psychology from Columbia University.

I recently saw an estimate that if you took all the novel coronaviruses in the world (the actual viruses, not patients), you could fit them into a bucket no more than a couple of liters in volume. A huge impact has been wrought by a very small amount of stuff. The world of viruses is vast and complicated, and we’re still learning some of its basic features. Today’s guest David Baltimore won the Nobel Prize in Physiology or Medicine for the discovery that genetic information in viruses could flow from RNA to DNA, establishing an exception to the Central Dogma of Biology. He is the author of the Baltimore Classification scheme for viruses, and has done important research in the role of viruses in diseases from AIDS to cancer. We talk about what viruses are, how they work, and the status of the novel coronavirus we are currently battling. David also has some strong opinions about public health and how we should be preparing for future outbreaks.Support Mindscape on Patreon.David Baltimore received his Ph.D. in molecular biology from the Rockefeller Institute. He is currently the Robert Andrews Millikan Professor of Biology at Caltech. At age 37 he was awarded the Nobel Prize, which he shared with Howard Temin and Renato Dulbecco.

The podcast reflects on the meaning of life, exploring concepts of life as a process, homeostasis, meaning vs. purpose, emergence of goals and purposes in living beings, creation of rules, and finding meaning in challenging times.

There are some problems for which it’s very hard to find the answer, but very easy to check the answer if someone gives it to you. At least, we think there are such problems; whether or not they really exist is the famous P vs NP problem, and actually proving it will win you a million dollars. This kind of question falls under the rubric of “computational complexity theory,” which formalizes how hard it is to computationally attack a well-posed problem. Scott Aaronson is one of the world’s leading thinkers in computational complexity, especially the wrinkles that enter once we consider quantum computers as well as classical ones. We talk about how we quantify complexity, and how that relates to ideas as disparate as creativity, knowledge vs. proof, and what all this has to do with black holes and quantum gravity.Support Mindscape on Patreon.Scott Aaronson received his Ph.D. in computer science from the University of California, Berkeley.
