Is a hotdog a sandwich? Well, that depends on your definition of a sandwich (and a hotdog), and according to the most recent research in cognitive science, the odds that your concept of a sandwich is the same as another person’s concept are shockingly low.

In this episode we explore how understanding why that question became a world-spanning argument in the mid 2010s helps us understand some of the world-spanning arguments vexing us today. 

Our guest is psychologist Celeste Kidd who studies how we acquire and conceptualize information, form beliefs around those concepts, and, in general, make sense of the torrent of information blasting our brains each and every second. Her most recent paper examines how conceptual misalignment can lead to semantic disagreements, which can lead us to talk past each other (and get into arguments about things like whether hotdogs are sandwiches).

This is the third episode in a three-part series about how to have difficult conversations with people who see the world differently, how to have better debates about contentious issues, and how to ethically and scientifically persuade one another about things that matter – in short, this is a three-part series about How Minds Change (which is also the title of my new book).

There seems to be a movement afoot, a new wave of nonfiction about how to reduce all this argumentative madness and epistemic chaos. I want to boost everyone’s signal on this issue, so I thought it would be nice to collaborate instead of compete, since that’s part of what we are all proselytizing with these books.

So this episode’s guest is Anand Giridharadas, the author of The Persuaders – a book about activists, politicians, educators, and everyday citizens who are on the ground working to change minds, bridge divisions, and fight for democracy.

So this episode’s guest is Bo Seo, the author of Good Arguments – a book about how he became a world debate champion in which he not only teaches us how to apply what he has learned to everyday life, but imagines communities built around, not despite, constant arguing and disagreement.

Seo says that a political life without constant disagreement would be impoverished. As he puts it, quote, “Nations are, at their best, evolving arguments. As he writes, “In a liberal democracy, good arguments are not what societies should do but also what they should be.” See believes that on well curated, well moderated platforms, ones that value good faith interactions, arguing and disagreement would flip from being catalysts for polarization to the very engine of depolarization and change. In the interview, he not only tells us how to defend ourselves against bad arguments, but explains how in his mind a great democracy isn’t a place where everyone agrees and sees eye-to-eye, but one where we work to have better quality disagreements.

So this episode’s guest is Mónica Guzmán, the author of I Never Thought of It That Way – a book with very practical advice on how to have productive conversations in a polarized political environment via authentic curiosity about where people’s opinions, attitudes, and values come from. In short, it’s about how to reduce polarization and learn from those with whom we disagree by establishing the sort of dynamic in which they will eagerly learn from us as well.

In this episode, we sit down with famed stage magician, infamous instructor of the school of scams, Brian Brushwood, whose new podcast explores the world’s greatest con artists and con jobs from World War II to modern game shows. 

It’s February. It’s that time of year when we start to wonder if we might not follow through with our New Year’s resolutions. It’s that time of the year when procrastination becomes a centerpiece of our psychological concerns.

If you only just now started working and answering emails and eating properly, that this just means you are a normal human living in really weird times, and everyone else is also slowly, and begrudgingly, starting to accept the fact that it is 2023 as well

Our guest in this episode is professor, author, therapist, and speaker Britt Frank, a trauma specialist who treats people with a unique and powerful set of techniques and approaches which, taken together, help clients to get out of the feeling of being STUCK. Author of The Science of Stuck, she says, “Procrastination is not a character flaw. Nor is it a sign of weakness. Nor is it a sign of laziness.⁣ Procrastination is an indicator that internal consent has not been given. When our inner parts are distressed, afraid, sad, angry, grief-stricken or anxious, it is important to listen to their concerns, not to shame them or coerce them into action.⁣”

In the show you’ll learn about the physiological origins of procrastination – the inner brake pedal and gas pedal – and what to do to escape the two different versions of this universal challenge to getting unstuck and getting things done.
