285 | Nate Silver on Prediction, Risk, and Rationality Aug 12, 2024

Show notes

Being rational necessarily involves engagement with probability. Given two possible courses of action, it can be rational to prefer the one that could possibly result in a worse outcome, if there's also a substantial probability for an even better outcome. But one's attitude toward risk -- averse, tolerant, or even seeking -- also matters. Do we work to avoid the worse possible outcome, even if there is potential for enormous reward? Nate Silver has long thought about probability and prediction, from sports to politics to professional poker. In his his new book On The Edge: The Art of Risking Everything, Silver examines a set of traits characterizing people who welcome risks.

AMA | August 2024 Aug 05, 2024

Show notes

Welcome to the August 2024 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!

284 | Doris Tsao on How the Brain Turns Vision Into the World Jul 29, 2024

Show notes

The human brain does a pretty amazing job of taking in a huge amount of data from multiple sensory modalities -- vision, hearing, smell, etc. -- and constructing a coherent picture of the world, constantly being updated in real time. (Although perhaps in discrete moments, rather than continuously, as we learn in this podcast...) We're a long way from completely understanding how that works, but amazing progress has been made in identifying specific parts of the brain with specific functions in this process. Today we talk to leading neuroscientist Doris Tsao about the specific workings of vision, from how we recognize faces to how we construct a model of the world around us.

283 | Daron Acemoglu on Technology, Inequality, and Power Jul 22, 2024

Show notes

Change is scary. But sometimes it can all work out for the best. There's no guarantee of that, however, even when the change in question involves the introduction of a powerful new technology. Today's guest, Daron Acemoglu, is a political economist who has long thought about the relationship between economics and political institutions. In his most recent book (with Simon Johnson), Power and Progress: Our Thousand-Year Struggle Over Technology and Prosperity, he looks at how technological innovations affect the economic lives of ordinary people. We talk about how such effects are often for the worse, at least to start out, until better institutions are able to eventually spread the benefits more broadly.

282 | Joel David Hamkins on Puzzles of Reality and Infinity Jul 15, 2024

Show notes

The philosophy of mathematics would be so much easier if it weren't for infinity. The concept seems natural, but taking it seriously opens the door to counterintuitive results. As mathematician and philosopher Joel David Hamkins says in this conversation, when we say that the natural numbers are "0, 1, 2, 3, and so on," that "and so on" is hopelessly vague. We talk about different ways to think about the puzzles of infinity, how they might be resolved, and implications for mathematical realism.

281 | Samir Okasha on the Philosophy of Agency and Evolution Jul 01, 2024

Show notes

Just like with physics, in biology it is perfectly possible to do most respectable work without thinking much about philosophy, but there are unmistakably foundational questions where philosophy becomes crucial. When do we say that a collection of matter (or bits) is alive? When does it become an agent, capable of making decisions? What are the origins of morality and altruistic behavior? We talk with one of the world's leading experts, Samir Okasha, about the biggest issues in modern philosophy of biology.

280 | François Chollet on Deep Learning and the Meaning of Intelligence Jun 24, 2024

Show notes

Which is more intelligent, ChatGPT or a 3-year old? Of course this depends on what we mean by "intelligence." A modern LLM is certainly able to answer all sorts of questions that require knowledge far past the capacity of a 3-year old, and even to perform synthetic tasks that seem remarkable to many human grown-ups. But is that really intelligence? François Chollet argues that it is not, and that LLMs are not ever going to be truly "intelligent" in the usual sense -- although other approaches to AI might get there.

279 | Ellen Langer on Mindfulness and the Body Jun 17, 2024

Show notes

For those of us who are not dualists, the mind arises from our physical bodies -- mostly the brain, but the rest of the body has a role to play. And yet it remains tempting to treat the mind as a thing in itself, disconnected from how the body is doing. Ellen Langer is a psychologist who is one of the foremost researchers on the idea of mindfulness -- the cognitive skill of paying to one's thoughts, as well as to one's external environment. Her most recent book is The Mindful Body: Thinking Our Way to Chronic Health. We talk about how our state of mind can effect the functions of our body, sometimes in surprising ways.

278 | Kieran Healy on the Technology of Ranking People Jun 10, 2024

Show notes

We claim to love all of our children, friends, and students equally. But perhaps deep down you assign a ranking to them, from favorite to not-so-favorite. Ranking and quantifying people is an irresistible human tendency, and modern technology has made it ubiquitous. In this episode I talk with sociologist Kieran Healy, who has co-authored (with Marion Fourcade) the new book The Ordinal Society, about how our lives are measured and processed by the technological ecosystem around us. We discuss how this has changed how relate to ourselves and the wider world.
