Welcome to the May 2023 Ask Me Anything episode of Mindscape! These monthly excursions are funded by Patreon supporters (who are also the ones asking the questions). We take questions asked by Patreons, whittle them down to a more manageable number — based primarily on whether I have anything interesting to say about them, not whether the questions themselves are good — and sometimes group them together if they are about a similar topic. Enjoy! Support Mindscape on Patreon . Se...
May 08, 2023•3 hr 8 min•Transcript available on Metacast What is the mind, and what does it try to do? An overly simplified materialist view might be that the mind emerges from physical processes in the brain. But you can be a materialist and still recognize that there is more to the mind than just the brain: the rest of our bodies play a role, and arguably we should count physical artifacts that contribute to our memory and cognition as part of "the mind." Or so argues today's guest, philosopher/cognitive scientist Andy Clark. As to what the mind doe...
May 01, 2023•1 hr 22 min•Ep 235•Transcript available on Metacast Eukaryotic cells manage to pull off a number of remarkable feats. One is packing quite a long DNA molecule, with potentially billions of base pairs, into a tiny central nucleus. A key role is played by histones , proteins that provide scaffolding for DNA to wrap around. Histones also appear in archaea (one of the other domains of life), but until recently there wasn't evidence for them in bacteria (the final of the three domains). Todays guest, Tobias Warnecke, is an author on a rece...
Apr 24, 2023•1 hr 7 min•Ep 234•Transcript available on Metacast Here at the Mindscape Podcast, we are firmly pro-reason. But what does that mean, fundamentally and in practice? How did humanity come into the idea of not just doing things, but doing things for reasons? In this episode we talk with cognitive scientist Hugo Mercier about these issues. He is the co-author (with Dan Sperber) of The Enigma of Reason , about how the notion of reason came to be, and more recently author of Not Born Yesterday , about who we trust and what we believe. He a...
Apr 17, 2023•1 hr 13 min•Ep 233•Transcript available on Metacast If you knew exactly when every person was going to die, or require medical care, you could make a killing buying and selling insurance. Nobody knows these things, of course -- the future is hard to predict -- but some people know something about the future that other people don't. This sets up adverse selection: the ability of one party to leverage information another party doesn't have, in order to gain an economic advantage. Economist Amy Finkelstein is an expert in this phenomenon, as well as...

Apr 03, 2023•4 hr 4 min•Transcript available on Metacast Human beings are small compared to the universe, but we're very important to ourselves. Humanism can be thought of as the idea that human beings are themselves the source of meaningfulness and mattering in our lives, rather than those being granted to us by some higher power. In today's episode, Sarah Bakewell discusses the origin and evolution of this dramatic idea. Humanism turns out to be a complex thing; there are religious humanists and atheistic anti-humanists. Her new book is Humanl...
Mar 27, 2023•1 hr 21 min•Ep 231•Transcript available on Metacast Welcome to another episode of Sean Carroll's Mindscape. Today, we're joined by Raphaël Millière, a philosopher and cognitive scientist at Columbia University. We'll be exploring the fascinating topic of how artificial intelligence thinks and processes information. As AI becomes increasingly prevalent in our daily lives, it's important to understand the mechanisms behind its decision-making processes. What are the algorithms and models that underpin AI, and how do they differ from human thought p...
Mar 20, 2023•2 hr 58 min•Ep 230•Transcript available on Metacast Every time our brain does some thinking, there are associated physical processes. In particular, electric currents and charged particles jump between neurons, creating associated electromagnetic fields. These fields can in principle be detected with proper technology, opening the possibility for reading your mind. That technology is currently primitive, but rapidly advancing, and it's not too early to start thinking about legal and ethical consequences when governments and corporations have acce...

Mar 06, 2023•3 hr 1 min•Transcript available on Metacast God is dead, as Nietzsche’s madman memorably reminded us. So what are we going to do about it? If there is no powerful force out there to guide us and give meaning to our lives, how are we supposed to live? Do we have to come up with meaning and purpose ourselves ? Apparently so, and how to pull it off was a major question addressed by the existentialist movement. Skye Cleary turns to Simone de Beauvoir, in particular, for thoughts on how to construct an authentic life. Her recent book is&...
Feb 27, 2023•1 hr 17 min•Ep 228•Transcript available on Metacast Most of us strive to be good, moral people. When we are doing that striving, what is happening in our brains? Some of our moral inclinations seem pretty automatic and subconscious. Other times we have to sit down and deploy our full cognitive faculties to reason through a tricky moral dilemma. I talk with psychologist Molly Crockett about where our moral intuitions come from, how they can sometimes serve as cover for bad behaviors, and how morality shapes our self-image.

Feb 20, 2023•1 hr 12 min•Ep 227•Transcript available on Metacast Cities are incredibly important to modern life, and their importance is only growing. As Geoffrey West points out, the world is adding urban areas equivalent to the population of San Francisco once every four days. How those areas get designed and structured is a complicated interplay between top-down planning and the collective choices of millions of inhabitants. As the world is changing and urbanization increases, it will be crucial to imagine how cities might serve our needs even ...

Feb 06, 2023•3 hr 8 min•Transcript available on Metacast Human beings have developed wondrous capacities to take in information about the world, mull it over, think about a suite of future implications, and decide on a course of action based on those deliberations. These abilities developed over evolutionary history for a variety of reasons and under a number of different pressures. But one crucially important aspect of their development is their social function. According to Michael Tomasello, we developed agency and cognition and even mo...
Jan 30, 2023•1 hr 22 min•Ep 225•Transcript available on Metacast So you have some information — how are you going to share it with and present it to the rest of the world? There has been a long history of organizing and displaying information without putting too much thought into it, but Edward Tufte has done an enormous amount to change that. Beginning with The Visual Display of Quantitative Information , and continuing to his new book Seeing With Fresh Eyes: Meaning, Space, Data, Truth , Tufte’s works have shaped how we think about charts, graphs, and...
Jan 23, 2023•1 hr 16 min•Ep 224•Transcript available on Metacast There are few human impulses more primal than the desire for explanations. We have expectations concerning what happens, and when what we experience differs from those expectations, we want to know the reason why. There are obvious philosophy questions here: What is an explanation? Do explanations bottom out, or go forever? But there are also psychology questions: What precisely is it that we seek when we demand an explanation? What makes us satisfied with one? Tania Lombrozo is a psychologist w...
Jan 16, 2023•1 hr 11 min•Ep 223•Transcript available on Metacast Quantum gravity research is inspired by experiment — all of the experimental data that supports quantum mechanics, and supports general relativity — but it’s only inspiration, not detailed guidance. So it’s easy to “do research on quantum gravity” and get lost in a world of toy models and mathematical abstraction. Today’s guest, Andrew Strominger, is a leading researcher in string theory and quantum gravity, and one who has always kept his eyes on the prize: connecting to the real world. We talk...
Jan 09, 2023•1 hr 25 min•Ep 222•Transcript available on Metacast One of the most powerful of all human capacities is the ability to imagine ourselves in hypothetical situations at different times. We can remember the past, but also conjure up possible futures that haven’t yet happened. This simple ability underlies our capability to organize socially and make contracts with other people. Today’s guest, psychologist Adam Bulley, argues that it’s the primary feature that makes us recognizably human, as he argues in the new book The Invention of Tomorrow: ...
Jan 02, 2023•1 hr 21 min•Ep 221•Transcript available on Metacast Welcome to that beloved Mindscape annual tradition, the Holiday Message. An opportunity for a quicker and less-well-thought-out solo episode to round off another year. Ironically, this year the theme is the importance of slowing down and thinking things out really well! Illustrated by two things that have been on my mind: a couple of internet/tech kerfuffles (Elon Musk buying Twitter, Sam Bankman-Fried and the collapse of FTX), and the distinction between foundations of physics and “regular” phy...
Dec 19, 2022•48 min•Transcript available on Metacast Life is rich with moments of uncertainty, where we’re not exactly sure what’s going to happen next. We often find ourselves in situations where we have to choose between different kinds of uncertainty; maybe one option is very likely to have a “pretty good” outcome, while another has some probability for “great” and some for “truly awful.” In such circumstances, what’s the rational way to choose? Is it rational to go to great lengths to avoid choices where the worst outcome is very bad? Lara Buc...

Dec 05, 2022•3 hr 16 min•Transcript available on Metacast It’s easy enough to proclaim that we are curious creatures, but what does that really mean? What kinds of curiosity are there? And how does curiosity arise in our brains? Perry Zurn and Dani Bassett are a philosopher and neuroscientist, respectively (as well as twins), whose new book Curious Minds: The Power of Connection explores these questions through an interdisciplinary lens. We break down the different ways that curiosity can manifest — collecting and creating loose knowledge n...
Nov 28, 2022•1 hr 3 min•Ep 219•Transcript available on Metacast Stephen Hawking’s discoveries of black hole radiation, entropy, and the information-loss problem have both taught us an enormous amount about the relationship between quantum mechanics and gravity, and also left us with some knotty puzzles. One major insight is the holographic principle: the information describing a black hole can be thought of as living on the event horizon (the two-dimensional boundary of the hole), rather than distributed throughout its volume, as normal physics would lead us...
Nov 21, 2022•1 hr 22 min•Ep 218•Transcript available on Metacast Why do people voluntarily hand over authority to a government? Under what conditions should they do so? These questions are both timeless and extremely timely, as modern democratic governments struggle with stability and legitimacy. They also bring questions from moral and political philosophy into conversations with empirically-minded social science. Margaret Levi is a leading political scientist who has focused on political economy and the nature of trust in government and other in...

Nov 07, 2022•3 hr•Transcript available on Metacast People have a complicated relationship to mathematics. We all use it in our everyday lives, from calculating a tip at a restaurant to estimating the probability of some future event. But many people find the subject intimidating, if not off-putting. John Allen Paulos has long been working to make mathematics more approachable and encourage people to become more numerate. We talk about how people think about math, what kinds of math they should know, and the role of stories and narrative to make ...
Oct 31, 2022•1 hr 11 min•Ep 216•Transcript available on Metacast The founders of statistical mechanics in the 19th century faced an uphill battle to convince their fellow physicists that the laws of thermodynamics could be derived from the random motions of microscopic atoms. This insight turns out to be even more important than they realized: the emergence of patterns characterizing our macroscopic world relies crucially on the increase of entropy over time. Barry Loewer has (in collaboration with David Albert) been developing a theory of the Mentaculu...
Oct 24, 2022•2 hr 34 min•Ep 215•Transcript available on Metacast It’s a big universe we live in, so it comes as no surprise that big numbers are needed to describe it. There are roughly 10^22 stars in the observable universe, and about 10^88 particles altogether. But these numbers are nothing compared to some of the truly ginormous quantities that mathematicians have found to talk about, with inscrutable names like Graham’s Number and TREE(3). Could such immense numbers have any meaningful relationship with the physical world? In hi...
