The internet has made it so much easier for people to talk to each other, in a literal sense. But it hasn’t necessarily made it easier to have rewarding, productive, good-faith conversations. Here I talk with sociologist Rod Graham about what kinds of conversations the internet does enable, and should enable, and how we can work to make them better. We discuss both how social media are used for nefarious purposes, from cyberbullying to driving extremism, but also how they can be mobilized for more lofty goals. We also get into some of the lost nuances in conventional discussions of race, including how many minorities are more culturally conservative than an oversimplified narrative would lead us to believe, and the tricky relationship between online discourse and social cohesion.Support Mindscape on Patreon.Roderick Graham received his Ph.D. in sociology from the City University of New York. He is currently an Associate Professor of Sociology and Criminal Justice at Old Dominion University, and serves as the coordinator of the university’s Cybercriminology Bachelor’s program.

In July 2018, 12 youth soccer players and their coach found themselves trapped 6 miles deep in a cave with no food or water and depleting oxygen. The rock formed maze became almost completely submerged as the water rose to levels nearly impossible for survival. There was no light and no way to communicate with the outside world. The first season of Wondery’s new original series Against the Odds takes you into the incredible events of when an adventurous group of teens found themselves fighting to save their lives, and the brave heroes that gave them their only chance at survival. With step by step recounts, experience for yourself what it was like to be in their shoes, and how they survived against the odds. Listen to Against the Odds at wondery.fm/ATO.
In our postmodern world, studying the classics of ancient Greece and Rome can seem quaint at best, downright repressive at worst. (We are talking about works by dead white men, after all.) Do we still have things to learn from classical philosophy, drama, and poetry? Shadi Bartsch offers a vigorous affirmative to this question in two new books coming from different directions. First, she has newly translated the Aeneid, Vergil’s epic poem about the founding myth of Rome, bringing its themes into conversation with the modern era. Second, in the upcoming Plato Goes to China, she explores how a non-Western society interprets classic works of Western philosophy, and what that tells us about each culture.Support Mindscape on Patreon.Shadi Bartsch-Zimmer received her Ph.D. in Classics from the University of California, Berkeley.

Welcome to the February 2021 Ask Me Anything episode of Mindscape! These are funded by Patreon supporters (who are also the ones asking the questions). This month is in what has been the conventional format, where I just try my best to answer every question. But it’s growing a bit unwieldy, so going forward I might just try to pick my favorite questions and answer them in greater detail. We shall see.Support Mindscape on Patreon.
A common argument against free will is that human behavior is not freely chosen, but rather determined by a number of factors. So what are those factors, anyway? There’s no one better equipped to answer this question than Robert Sapolsky, a leading psychoneurobiologist who has studied human behavior from a variety of angles. In this conversation we follow the path Sapolsky sets out in his bestselling book Behave, where he examines the influences on our behavior from a variety of timescales, from the very short (signals from the amygdala) to the quite ancient (genetic factors tracing back tens of thousands of years and more). It’s a dizzying tour that helps us understand the complexity of human action.Support Mindscape on Patreon.Robert Sapolsky received his Ph.D. in neuroendocrinology from Rockefeller University. He is currently the John and Cynthia Fry Gunn Professor of Biology, Neurology, and Neurosurgery at Stanford University.

It’s a truism that what we see about the world is a small fraction of all that exists. At the simplest level of physics and biology, our senses are drastically limited; we only see a narrow spectrum of electromagnetic waves, and we only hear a narrow band of sound. We don’t feel neutrinos or dark matter at all, even as they pass through our bodies, and we can’t perceive microscopic objects. While science can help us overcome some of these limitations, they do shape how we think about the world. Ziya Tong takes this idea and expands it to include the parts of our social and moral worlds that are effectively invisible to us — from where our food comes from to how we decide how wealth is allocated in society.Support Mindscape on Patreon.Ziya Tong received a B.A. in psychology and sociology from the University of British Columbia, and an M.A. in communications from McGill University. She has served as host, writer, director, producer, and reporter from a number of science programs, most notably Daily Planet on Discovery Canada.

Here is a special bonus punishment treat for Mindscape listeners: an interview of me, by David Zierler of the American Institute of Physics’s Oral History project. This is a fantastic project that collects interviews with influential physicists of all ages, and apparently sometimes less-influential physicists. So if you’d like to hear my (academic) life story boiled down to a mere four hours, here you go!Support Mindscape on Patreon.It’s well worth checking out the AIP Oral History Project website, which has over 1000 fascinating interviews with physicists from different decades. The transcript of this particular interview can be found there. Thanks to David and the AIP for letting us include this as a bonus podcast episode.
As a semi-outsider, it’s fun for me to watch as a new era dawns in biology: one that adds ideas from physics, big data, computer science, and information theory to the usual biological toolkit. One of the big areas of study in this burgeoning field is the relationship between the basic bioinformatic building blocks (genes and proteins) to the macroscopic organism that eventually results. That relationship is not a simple one, as we’re discovering. Standard metaphors notwithstanding, an organism is not a machine based on genetic blueprints. I talk with biologist and information scientist Michael Levin about how information and physical constraints come together to make organisms and selves.Support Mindscape on Patreon.Michael Levin received his Ph.D. in genetics from Harvard University. He is currently Distinguished Professor and Vannevar Bush Chair in the Biology department at Tufts University, and serves as director of the Tufts Center for Regenerative and Developmental Biology.

The possible existence of technologically advanced extraterrestrial civilizations — not just alien microbes, but cultures as advanced (or much more) than our own — is one of the most provocative questions in modern science. So provocative that it’s difficult to talk about the idea in a rational, dispassionate way; there are those who loudly insist that the probability of advanced alien cultures existing is essentially one, even without direct evidence, and others are so exhausted by overblown claims in popular media that they want to squelch any such talk. Astronomer Avi Loeb thinks we should be taking this possibility seriously, so much so that he suggested that the recent interstellar interloper `Oumuamua might be a spaceship built by aliens. That got him in a lot of trouble. We talk about the trouble, about `Oumuamua, and the attitude scientists should take toward provocative ideas.Support Mindscape on Patreon.Abraham (Avi) Loeb received his Ph.D. in plasma physics from the Hebrew University of Jerusalem.

What is the world made of? How does it behave? These questions, aimed at the most basic level of reality, are the subject of fundamental physics. What counts as fundamental is somewhat contestable, but it includes our best understanding of matter and energy, space and time, and dynamical laws, as well as complex emergent structures and the sweep of the cosmos. Few people are better positioned to talk about fundamental physics than Frank Wilczek, a Nobel Laureate who has made significant contributions to our understanding of the strong interactions, dark matter, black holes, and condensed matter, as well as proposing the existence of time crystals. We talk about what we currently know about fundamental physics, but also the directions in which it is heading, for better and for worse.Support Mindscape on Patreon.Frank Wilczek received his Ph.D. in physics from Princeton University.

The first full week of 2021 has been action-packed for those of us in the United States of America, for reasons you’re probably aware of, including a riotous mob storming the US Capitol. The situation has spurred me to take the unusual step of doing a solo podcast in response to current events. But never fear, I’m not actually trying to analyze current events for their own sakes. Rather, I’m using them as a jumping-off point for a more general discussion of how democracy is supposed to work and how we can make it better. We’ve talked about related topics recently with Cornel West and David Stasavage, but there are things I wanted to say in my own voice that fit well here. Politics is important everywhere, and it’s a crucial responsibility for those of us who live in societies that aspire to be participatory and democratic. We have to think these things through, and that’s what this podcast is all about.Support Mindscape on Patreon.Apologies to Alexis de Toqueville, who wrote an important book whose name I stole, and who is mentioned nowhere in this episode.
We all know stereotypes about people from different countries; but we also recognize that there really are broad cultural differences between people who grow up in different societies. This raises a challenge when most psychological research is performed on a narrow and unrepresentative slice of the world’s population — a subset that has accurately been labeled as WEIRD (Western, Educated, Industrialized, Rich, and Democratic). Joseph Henrich has argued that focusing on this group has led to systematic biases in how we think about human psychology. In his new book, he proposes a surprising theory for how WEIRD people got that way, based on the Church insisting on the elimination of marriage to relatives. It’s an audacious idea that nudges us to rethink how the WEIRD world came to be.Support Mindscape on Patreon.Joseph Henrich received his Ph.D. in anthropology from UCLA.

Welcome to the third annual Mindscape Holiday Message! Just a chance for me to be a little more chatty and informal than usual, although as it turned out this isn’t all that different from a conventional solo episode. With the difference that what I’m talking about — a phenomenon called “cosmic birefringence” — has played a big part in my personal scientific career, so I get to be a bit autobiographical.Every photon has a direction of polarization, which generally remains fixed as the photon travels through space. Birefringence is an effect by which the polarization rotates rather than staying fixed. It can happen in materials, but generally not in outer space. But there are exotic physics ideas that could cause such a rotation, including the dynamical dark energy candidate known as quintessence. People have put limits on such cosmic birefringence for a while now, but recently there was a claim that there might be a nonzero amount of birefringence visible in the polarization of the cosmic microwave background! Still very tentative, but if this hint turns into real evidence, it would big extremely big news for our understanding of physics and cosmology, possibly helping us pinpoint the nature of dark energy.Show notes, links, transcript: https://www.preposterousuniverse.com/podcast/2020/12/21/holiday-message-2020-the-screwy-universe/
Many characteristics go into making human beings special — brain size, opposable thumbs, etc. Surely one of the most important is language, and in particular the ability to learn new sounds and use them for communication. Many other species communicate through sound, but only a very few — humans, elephants, bats, cetaceans, and a handful of bird species — learn new sounds in order to do so. Erich Jarvis has been shedding enormous light on the process of vocal learning, by studying birds and comparing them to humans. He argues that there is a particular mental circuit in the brains of parrots (for example) responsible for vocal learning, and that it corresponds to similar circuits in the human brain. This has implications for the development of intelligence and other important human characteristics.Support Mindscape on Patreon.Erich Jarvis received his Ph.D. in Animal Behavior and Molecular Neurobehavior from Rockefeller University. He is currently a professor in the Laboratory of Neurogenetics of Language at Rockefeller and an investigator at the Howard Hughes Medical Institute. Among his many awards are the Alan T.

Getting into the swing of things here with monthly Ask Me Anything episodes. If you missed the explanation last month, there is a Patreon page for people who wish to support Mindscape with a small donation per episode. Benefits include a warm feeling, social status, access to ad-free versions of the podcast, and the ability to ask questions once per month, which I answer over the course of a hilariously long podcast. Thanks to the generosity of Patreon supporters, we are now making the fruits of these monthly adventures available on the regular podcast feed.Here is the December 2020 edition. Note that there won’t be a January 2021 edition, as I take a break from podcasting for the holidays. Have a good one everybody!Support Mindscape on Patreon.
Those of us living in democracies tend to take the idea for granted. We forget what an audacious, radical idea it is to put government power into the hands of literally all of the citizens of a country. Where did such an idea come from, and where is it going? Political scientist David Stasavage has written an ambitious history of democracy worldwide, in which he makes a number of unconventional points. The roots of democracy go much further back than we often think; the idea wasn’t invented in Athens, but can be found in a large number of ancient societies. And the resurgence of democracy in Europe wasn’t because that continent was especially advanced, but precisely the opposite. These insights have implications for what the future of democracy has in store.Support Mindscape on Patreon.David Stasavage received his Ph.D. in Government from Harvard University. He is currently Dean for the Social Sciences and the Julius Silver Professor in the Department of Politics at New York University and an Affiliated Professor in NYU’s School of Law.

Aristotle conceived of the world in terms of teleological “final causes”; Darwin, or so the story goes, erased purpose and meaning from the world, replacing them with a bloodless scientific algorithm. But should we abandon all talk of meanings and purposes, or instead conceptualize them as emergent rather than fundamental? Philosophers (and former Mindscape guests) Alex Rosenberg and Daniel Dennett recently had an exchange on just this subject, and today we’re going to hear from a working scientist. David Haig is a geneticist and evolutionary biologist who argues that it’s perfectly sensible to perceive meaning as arising through the course of evolution, even if evolution itself is purposeless.Support Mindscape on Patreon.David Haig received his Ph.D. in biology from Macquarie University. He is currently the George Putnam Professor of Organismic and Evolutionary Biology at Harvard University.

Time! It doesn’t stop, psychological effects of being under lockdown notwithstanding. How we experience time depends on our situation, but time itself just marches forward. Unless, of course, it’s possible to travel to the past, as countless science-fiction scenarios have depicted. But does that really make sense? Couldn’t we then change the past, even so dramatically that our own existence would never have happened? In this solo podcast I talk about both the physics and fiction of time travel. I point out that it might be allowed by the laws of physics, and explain how that would work, but that we really don’t know. And I try to make sense of some of the less-sensible depictions of cinematic time travel. Coming up with a logical theory that could account for Back to the Future isn’t easy, but podcasting isn’t for the squeamish.Support Mindscape on Patreon.But wait, there’s more! I was contacted by Janna Levin, who we fondly remember from Episode 27. Janna moonlights as Chair and Director of Sciences at Pioneer Works, an institution dedicated to bringing together creative people in art and science. Like the rest of us, they’ve been looking for ways to offer more online content in these pandemic times, so we thought about ways to collaborate. Here’s what they came up with: artist Azikiwe Mohammed has created an animated video backdrop to this podcast episode. The visuals are trippy, colorful, and inspired by (without trying to directly illustrate) what I talk about in the episode.

As you have likely heard me mention before, I have an account on Patreon, where people can sign up to donate a dollar or two per episode of Mindscape. In return they get two tangible (if minor) benefits. First, they get to listen to the podcast without any ads. Second, once per month I do an Ask Me Anything episode, where patrons are allowed to ask any question they like, and I do my best to answer as many as I can.Patreon supporters have kindly agreed to let these monthly AMA episodes be released to the general public (though they maintain the right actually ask the questions). I announced that I’d be doing this a while back, but with the cost structure I had with my podcast host it turned out to be prohibitively expensive for me. But now we’ve got that all figured out! So now, and hopefully going forward, these AMAs will be part of the regular podcast feed. They will be released sometime in the middle of each month, not as part of the usual Monday weekly series, so they won’t get numbers of their own.
Emotions are at the same time utterly central to who we are — where would we be without them? — and also seemingly peripheral to the “real” work our brains do, understanding the world and acting within it. Why do we have emotions, anyway? Are they hardwired into the brain? Lisa Feldman Barrett is one of the world’s leading experts in the psychology of emotions, and she emphasizes that they are more constructed and less hard-wired than you might think. How we feel and express emotions can vary from culture to culture or even person to person. It’s better to think of emotions of a link between affective response and our behaviors.Support Mindscape on Patreon.Lisa Feldman Barrett received her Ph.D. in psychology from the University of Waterloo.

The bit that never makes sense to me about "hard incompatibility" – and nobody ever seems to bring up – is: if we don't have control over our decisions and 90+% is subconscious, HOW COME WE MAKE UP EXPLANATIONS AND JUSTIFICATIONS? This about it and it's profoundly nonsensical. If our decisions aren't decisions, then our justifications for them are also automagic. In fact all research into the subject is the result of random endocrine reactions to ambient temperature fluctuations. Nobody has invented the internet, or the dishwasher, or written War and Peace. All of these "had" to happen because of biology? that's just dumb. I get it that biology will tip the scales and make one more likely to go A instead of B, and another the reverse. But it's an impossible jump to believe that these processes do not combine at a higher level to create a "supergroup", i.e a mind with its own agency.

Why don't you venture out of your niche and address the plethora of historical evidence of Ancient Aliens. Have a second look at the pryamids. Do you know that they contain measurements of the earth? Do you know what star system it connects to? How many other monoliths and pyramids around Earth have you looked into? Do you know what the Nahave you What about the star maps of the Dogon Tribe? What do you know about Dobekli Tepi? Or the Nazca Lines. Or military pilots describing impossible maneuvers they see. Or the many UFOs caught on camera---or the Phoenix Lights? You both said that scientist must look at all angles, not just radio waves. I know you have specialties, and we are talking about Omuamua(sp) from those backgrounds. However, I think your opinions on the likelihood of ETs existing should be kept to yourself, or else it should come with a disclaimer, that your ideas and data have not been interpreted in light of historical records. . lol. I would love to hear your ideas in response to those things it just seems like you would naturally be interested in these things and at least acknowledge them.

I loved this episode and now want to read Teresa's books. It's a timely topic and I'm glad Sean is having more guests like this (non-physics... it's just not an area of huge interest for me) because he's a great interviewer. I'd like Teresa's attitude and ideas to spread as quickly and as far as some of the more narrow-minded ones have done in the recent past...and I'm doing my best to help by listening more and questioning my own automatic reactions.
