Ep44 "Why can't you tickle yourself?" (Time Traveling Part 2) Jan 29, 2024

Show notes

Why are people who can't remember their past also unable to picture their future? Why do we get so anxious about the world changing around us? What should you advise the president if we find ourselves at war with extraterrestrials? And what does this have to do with Wayne Gretzky, or the Greek goddess of memory, or hitting a bottle to get ketchup onto your French fries? Join this week's episode to find out about one of the most important things brains do: simulations of possible futures.

Ep43 "How do we remember?" (Time Traveling Part 1) Jan 22, 2024

Show notes

How do billions of neurons store your home address, your ability to ride a bike, and the history of your life? How does memory work in the brain, and how is it different from the way a computer stores information? And what does any of this have to do with the Happy Birthday song, squirrels hiding acorns, bards memorizing epics, or people who cannot forget any of the events of their life? Join Eagleman to learn how and why your brain continually time travels to previous moments.

Ep42 "Is there any such thing as true news?" (Truth Part 3: Artificial Intelligence) Jan 15, 2024

Show notes

What role will AI play in the future of fake news and misinformation? What does this have to do with our brains’ internal models, with voice passwords, and with what Eagleman calls "the tall intelligence problem"? And why does he believe that these earliest days of AI are its golden age, and we are quickly heading for a balkanization? Join for today's episode about truth, misinformation, and artificial intelligence.

Ep41 "Is there any such thing as true news?" (Truth Part 2: the Internet) Jan 08, 2024

Show notes

What is the future of misinformation on the internet? Is it possible that the invention of the internet has improved access to truth? What does any of this have to do with the Oxford English Dictionary, Soviet agriculture, liberation technology, Kenyan elections, Barbra Streisand's house, and Twitter revolutions? Join Eagleman for a surprising foray into the thorny forest of truth in the age of the internet.

Ep40 "Is there any such thing as true news?" (Truth Part1) Jan 01, 2024

Show notes

We all worry about fake news. But is misinformation and disinformation really new? Join Eagleman for a deep dive into the past, present, and future of truth. Why do cameras not tell us what we think they do? What should we not forget about pamphleteering? And what does this have to do with agriculture in the USSR, or book banning in America, or dog whistles, or apps that only tell facts? And why is it so hard to understand the viewpoints of millions of brains at once? This week's episode is the first of a three-parter -- and today we tackle truth in the media.

Ep39 "What is the future of AI relationships?" Dec 18, 2023

Show notes

Why are our brains so wired for love? Could you fall head over heels for a bot? Might your romantic partner be more satisfied with a 5% better version of you? How does an AI bot plug right into your deep neural circuitry, and what are the pros and cons? And what will it mean when humans you love don’t have to die, but can live on in your phone forever? Join Eagleman for a deep dive into relationships, their AI future, and what it all means for our species.

Ep38 "Why is it hard to teach an old brain new tricks?" Dec 11, 2023

Show notes

Is it always harder to teach an old dog new tricks? Why is an older person slower to learn a new language but able to learn new faces easily? Why does Arnold Schwartzenegger have an accent but Mila Kunis doesn’t, even though neither spoke English as a child? Why is there a correlation between how tall a person is and how much salary they're likely to earn? What would it mean to say that you are born as many people but die as a single one? This week's episode dives into surprises about brain plasticity and why your flexibility changes throughout your lifetime.

Ep37 "What is Insanity?" Part 2 Dec 04, 2023

Show notes

What does the insanity defense mean in a court of law? And is there such a thing as temporary insanity? Is the twinkie defense a real thing? Can someone use premenstrual syndrome as a defense? And what does the legal wrestling around insanity tell us about the differences between brains: yours and other people’s, or even yours one day and yours the next day? How does law comport with science, and how are they sometimes like two people with quite different ways of looking at the world? Join to find out what happened to Andrea Yates, how the legal system deals with mental illness, and so much more.

Inner Cosmos Inbox 2 Nov 30, 2023

Show notes

Eagleman answers listeners questions.

Ep36 "What is Insanity?" Part 1 Nov 27, 2023

Show notes

What is the insanity defense? Are some people’s brains so different that it makes sense to use a different legal category? How does a legal system decide where the dividing line is? How are science and law strange bedfellows? Join us for the first of two episodes about the insanity defense: where it comes from, where it's going, and why it is so difficult to decide where to draw our societal lines.
