The Big Think Interview

For decades, atheists have used one move to dismantle the case for God: swap in an evil one and show that the arguments work just as well. Philosopher Jack Symes was convinced by it, and was 50,000 words into a book defending atheism when he noticed that the exercise kept tipping toward goodness. He threw out the manuscript and started over.

From von Neumann's blueprint, which predated the discovery of DNA, to viral genes that now help form our memories and placentas, Blaise Agüera y Arcas argues that function defines life more than material does, and that AI belongs in the same story. He explains why he thinks AGI is already here, and gives a blueprint for using AI without sacrificing your own mind.

Jonathan Rauch, author and senior fellow at the Brookings Institution, dives into the philosophy of liberalism, how it has created and transformed our institutions, and the state of truth in a world rife with misinformation.

Most of us can recite the benefits of exercise, gratitude, and patience while doing none of it. Tal Ben-Shahar calls this the Knowing-Doing gap, and our typical interventions, like retreats and month-long overhauls keep it open.

Two-time debate champion Bo Seo breaks down why arguments fail: the 4 bad-faith personas that hijack conversations, a four-question framework for picking fights worth having, and the surprising Cold War standoff between Nixon and Khrushchev that shows what staying composed under pressure actually looks like.

OBGYN Jen Gunter unpacks the science, history, and mythology of menstruation and menopause, and offers a guidebook to navigate the modern healthcare landscape.

Talent isn’t a gift we're born with – it’s a signal we’ve been reading completely wrong. Author Daniel Coyle breaks down the common traits shared by successful people, and why environment, not innate ability, is the variable that ties them all together.

Terence Tao has spent decades solving problems most people can't even state, and he says he's never had a single eureka moment. In this conversation, the UCLA mathematician and Fields Medalist breaks math down to six essential ideas: numbers, algebra, geometry, probability, analysis, and dynamics.

Every marriage’s disintegration is marked by the same four warning signs that researchers John and Julie Gottman can spot before a couple even finishes their first sentence. The founders of the Gottman Institute break down decades of lab research on why relationships collapse, and what to look for in a partner so they can make it 50 years by your side.

Stress has a branding problem. Clinical psychologist Dr. Lisa Damour argues that most of us have the wrong relationship with discomfort entirely, treating stress like a malfunction instead of what it actually is: a signal that we're growing.

Arthur Brooks studies happiness for a living, and he says the epidemic of depression and anxiety among young adults comes down to one culprit: a meaning crisis. Brooks walks through the biology of falling in love, the real formula behind human suffering, and why a Harvard study spanning 85 years found deep relationships to be the single strongest predictor of a happy old age.

Physician Giulia Enders spent years studying the gut before realizing no organ works alone. Here, she walks through 5 body parts — the lung, the immune system, the skin, the muscles, and the brain — and what each one reveals about how we work, heal, and recover.

Philosopher Jonny Thomson walks through Dietrich Bonhoeffer's 3 conditions for the kind of stupidity that destroys societies: outsourcing your thinking to an authority, willful ignorance, and conformity. He shows how each one shows up today, from AI answering our moral questions to political parties enforcing loyalty over conviction.

Psychologist Paul Bloom has spent his career studying the parts of human nature we often feel uncomfortable examining: why loneliness feels like starvation, why people are drawn to behaving poorly, why revenge feels righteous until it destroys everything. Bloom argues that the US doesn't actually have a loneliness epidemic, it has a solitude epidemic, one being accelerated by AI companionship.

A philosopher who walked away from an elite academic career to spend 3 years washing dishes in a monastery says that intellectual life has nothing to do with degrees. Zena Hitz argues that the real philosophers are taxi drivers, office clerks, prisoners: Everyday people who exist outside the cult of academia.

Steve Brusatte, the paleontologist behind Jurassic World's science and author of The Rise and Fall of the Dinosaurs and The Story of Birds, walks through what fossils actually prove versus what Hollywood invented. Brusatte traces dinosaurs back to footprints smaller than a house cat, found in Poland just after the worst mass extinction in Earth's history, and explains why those early survivors spent millions of years as background characters next to car-sized salamanders and armored crocodiles.

A retired Japanese engineer once memorized pi to over 111,000 digits using nothing but storytelling and visualization. He also forgot his wife's birthday that same year. Neuroscientist Lisa Genova uses this contradiction to dispel a persistent collective fear: that ordinary forgetting is an early warning sign of Alzheimer's.

Could depression, dementia, and poor oral health all have one uniting link? The gut microbiome contains 200 more genes than human cells, and research shows its strong impact on mental illness, brain health, and chronic inflammation. Professor of epidemiology at King's College London Tim Spector breaks down the science of how gut microbes produce the chemicals that shape your mood, your immune system, and your cognitive health, and why the standard Western diet has been systematically destroying them for 50 years.

About 40% of everything you do today is a habit your brain automated, and the neural loop driving it doesn't distinguish between good and bad habits. Charles Duhigg, author of The Power of Habit and Supercommunicators , explains why trying to eliminate a bad habit is neurologically futile and why the habit that scares you most irrationally is probably the one change that rewires everything else.

You only have a few seconds to make a first impression, and the non-verbal cues you’re sending may be silently working against any kindness your words communicate. Charisma is learned, not innate, and even if you consider yourself an “awkward” person, you can still hack positive reception. Body language expert Vanessa van Edwards shares a genius formula to create a lasting first impression while debunking body-language myths and these mistakes you’re probably making in social situations.
