Episodes
Ep74 "Why do we laugh?"
9/2/2024
From the brain’s point of view, what is humor? When something is funny, why do we breathe in and out rapidly? Do other animals laugh? Why do most jokes come in threes? What do mystery novelists, magicians, and comedians have in common? Could AI be truly funny? Join Eagleman this week to appreciate the tens of reasons and millions of years behind the tickling of your neural pathways.

Ep73 "How do we fool ourselves in the stock market?"
8/26/2024
What does neuroscience have to do with investment, and what does that have to do with Isaac Newton, the Dutch East India company, Kodak, the way zebras herd, our emotions, and almost 200 cognitive biases? Join Eagleman with guest Mark Matson, whose new book The American Dream dives into the cognitive illusions we face when trying to make investments.

Ep72 "How do you put yourself in other people's shoes (and can AI do it)?"
8/19/2024
You know that moment in the horror movie where the monster is coming closer, but the movie star doesn't see it? Why does that drive you crazy, and what does that teach us about brains? What is theory of mind, and why is it so important for everyone from poker players to conmen to stage magicians to novelists? Join us this week to dive into a fundamental skill of human brains -- and the question of whether current AI has any ability to simulate other people's minds.

Ep71 "Why do our memories drift? Part 2: Misremembering yourself"
8/12/2024
Is your notion of yourself built on narrative that may or may not be accurate? If someone told you an entirely false story about yourself, could you come to believe it? What does that have to do with six people who spent over a decade in prison together for a crime they didn't commit? Join Eagleman for part 2 of some mind-blowing conclusions about your account of your own life.
Duration:00:34:13
Ep70 "Why do our memories drift? Part 1: The War of the Ghosts"
8/5/2024
Why did lions look so strange in medieval European art? What does this have to do with Native American folklore, eyewitness memory of a car accident, or what a person remembers 3 years after witnessing the 9/11 attack on the World Trade Center? And what does any of this have to do with flashbulb memories, misinformation, and the telephone game that you played as a child? Join Eagleman for part 1 of an astonishing journey into what we believe about our memories.
Duration:00:33:52
Ep69 "Why do you see something everywhere after you've seen it once?"
7/29/2024
What does the Baader-Meinhof Group, a West German terrorist group from the 1970s, have to do with the front of your brain, attention, salience, and synchronicity? And why might you soon hear about the Baader-Meinhof Group again, not for political reasons, but for reasons to do with your own neural networks? Join Eagleman for a dive into how we take in the world around us -- and how we get fooled about the frequencies of events.
Duration:00:37:06
Ep68 "What if our brains worked a trillion times faster?"
7/22/2024
Why are the majority of stock trades decided by algorithms at timescales we can scarcely conceive of? What is it like to have the speed and power of a computer, and to be dealing with slow humans? Why are movies compelling, given that they are just a series of photographs flashed rapidly? And what happens if we someday discover planets with creatures who operate on totally different time scales? Join Eagleman this week for a deep dive into speed: the speed at which we operate, the speed at which our machines operate, and what this all means for the future as the divergence grows larger.
Duration:00:43:05
Ep67 "How did human brains get runaway intelligence? "
7/15/2024
We're the single species who composes symphonies, erects skyscrapers, builds computers, and regularly gets off the planet. But how did human intelligence evolve from our ancestors in the animal kingdom? And now that our species is scintillatingly shrewd, what does a knowledge of our road mean as we work to build intelligence artificially? Join Eagleman this week with Max Bennett, an especially smart human who illuminates a path through the 600 million year story of brain power in his book "A Brief History of Intelligence".
Duration:01:09:23
Ep66 "Why do brains love conspiracy theories?"
7/8/2024
Why are conspiracy theories a natural output of the brain? What do they have to do with puzzle-solving, cognitive dissonance, ingroups/outgroups, and storytelling? If you hear an unlikely explanation for something, what are effective and ineffective ways to assess it? Join Eagleman to understand from the point of view of the brain why conspiracy theories have always been so pervasive in human societies.
Duration:00:53:03
Ep65 "Why do brains so easily fall for magic tricks?"
7/1/2024
Did magicians discover tricks of the mind centuries before neuroscientists? Why can’t you see what they’re doing right in front of you? How do magicians steer your attention or appear to read your mind? Dive into the trapdoors of the human brain which allow the mind to get fooled. Join Eagleman with several guests: magician Robert Strong and cognitive neuroscientists Stephen Macknik and Susana Martinez-Conde.
Duration:01:07:34
Ep64 "Why do familiar things lose their shine (& what can we do about it)? "
6/24/2024
If you could get a kiss from your favorite celebrity, how long would you want to wait before receiving it? And why do things seem less meaningful or joyful over time than they were at the beginning? What does any of this have to do with Netflix releasing all the episodes of a new show at once, or why companies come out with new and improved products every year, or why French revolutionaries wanted to make a week five days long instead of seven? Join Eagleman and cognitive neuroscientist Tali Sharot to find out why everything dulls with time and what we can do to recover the shine.
Duration:00:51:14
Ep63 "Why do brains love faces?"
6/17/2024
Why do we have so much circuitry in the brain devoted to faces? Why does your electrical plug seem to look like a little face? Did aliens plant a signal for us on Mars, or are we looking at a quirk of our own brains? What is face blindness and what is a super recognizer? What does any of this have to do with looking at a magazine upside down, or why computer algorithms sometimes think a jack-o'-lantern is a person? Join Eagleman for a deep dive into something so fundamental as to be typically invisible.
Duration:00:36:18
Ep62 "Is it possible to rehumanize the enemy?"
6/10/2024
The brain easily forms ingroups and outgroups – and shows different responses when viewing one or the other. At the extreme, the brain stops seeing outgroup members as people, but more like objects. But are there ways to rehumanize? And in this context, what do heroes look like? In this episode, Eagleman talks with two men -- Maoz Inon and Aziz Abu Sarah -- one Israeli and one Palestinian. The two men, full of pain and sorrow, are fighting. But they are fighting side by side. They are fighting to repair the future. Learn what peacebuilders are, how they function, and what this has to do with the neuroscience of dehumanization, ingroups, outgroups, and the possibilities -- both political and neural -- for rehumanization.
Duration:00:59:59
Ep61 "When should you (not) trust your intuition?"
6/3/2024
Why do you sometimes feel that you trust this person but not that one -- for reasons you can't quite put your finger on? What signals does the brain vacuum up in your daily life, and what fraction of those does your conscious mind have access to? When does intuition steer us wrong? And what is the future of intuition, as we build new technologies to take the myriad signals racing around in the dark of our brains and bodies and bring them to light? Join Eagleman and his guest, cognitive neuroscientist Joel Pearson, to unpack when to trust and when to ignore the signals of intuition.
Duration:00:39:32
Ep60 "Can we think better by wrestling with conflicting ideas?"
5/27/2024
Why do we believe our own truths so strongly? What is steel-manning, and why is it so important? What does any of this have to do with F. Scott Fitzgerald, John Keats, or the future of our society? This week's episode deals with polarization and what we might do about it. Join Eagleman and his guest Isaac Saul, who works to represent different points of view in his newsletter Tangle -- all in the name of the intellectual humility that can blossom from grappling with conflicting ideas.
Duration:00:55:55
Ep59 "Do you visualize like I do?"
5/20/2024
How do brains picture things internally, and how might you and I imagine differently? How have recent discoveries completely changed the debate and the way we understand internal experience? What does this have to do with Disney's Fantasia, or Pixar's aphantasia? Strap in for some very wild surprises today about our internal experiences, with guest Ed Catmull, founder of Pixar Studios.
Duration:00:55:11
Ep58 "What do brains teach us about whether AI is creative?"
5/13/2024
From a neuroscience point of view, what is creativity? How does it shine light on the current lawsuits over large language models and whether they produce anything fundamentally new... or are simply remixing the old? How do the arts expose something important about what's happening in the human brain? What do we know about the cultural evolution of ideas? And what does any of this have to do with how cell phones got their names, and why koala bears don’t write novels? Join Eagleman and his guest, composer Anthony Brandt, as they uncover the surprises about creativity.
Duration:00:42:44
Ep57 "When should new technologies enter the courtroom?"
5/6/2024
Can we measure a lie from a blood pressure test, or pedophilia from a brain scan? And how should a judge decide whether the technology is good enough? What does this have to do with Ronald Reagan, or antisocial personality disorder, or how the television show CSI has impacted courtrooms? Today’s episode lives at the intersection of brains and the legal system. When are new neuroscience techniques allowed in courts, and when should they be?
Duration:00:40:34
Rebroadcast of Ep7 "Is AI truly intelligent? How would we know if it got there?"
4/29/2024
David is taking his birthday week off and wanted to re-share this episode due to it's ongoing relevance.
Modern AI is blowing everyone’s mind. But is it intelligent like humans, or is it just playing impressive statistical games? Could AI reach or exceed our level of intelligence, and how would we know when it gets there? Traditional tests for intelligence (Turing test, Lovelace test, etc) have long been surpassed, so Eagleman proposes a new kind of test.
Duration:00:46:19
Ep56 "Why do we care so much about touch?"
4/22/2024
Why does a cold pool feel warmer the second time you dip your toes in? Why does a safecracker run his fingers over sandpaper? Why do Mediterranean cultures touch each other more than Scandinavian cultures? Would it be great -- or not so great -- if you were unable to feel physical pain? Why does stubbing your toe have different sensations through time? And what does any of this have to do with cuddle puddles, NBA players bumping chests, or puppies sleeping in dog piles? Today’s episode is a love story about our sense of touch: what it is, how it works, and why it plays such a critical role in our lives.
