Thousands of years ago, humans crossed a land bridge from Siberia into Alaska. They tried to move south, but a two-mile-high, coast-spanning ice wall stood between them and the rest of the continent.
How did they get past it?
Scholars have fought over that question for decades. But in her book, “Origin,” Jennifer Raff says breakthroughs in genetics have given scientists an entirely new understanding of how the Americas were peopled and what happened in the millennia that followed.

Self-Improvement

Raise your hand if you've ever belittled a stranger online, made a decision based on astrology, or, heaven forbid, fallen for a conspiracy theory. No? Well, then, consider yourself lucky. And if your hand is raised, don't feel bad, because it turns out in our Information Age the cognitive biases that kept us alive a few millennia ago now make us susceptible to bouts of extreme irrationality. How this happened, and what we can do about it, is the subject of a brand new book by linguist Amanda Montell called "The Age of Magical Overthinking: Notes on Modern Irrationality."

MAGICAL OVERTHINKING: Why Modern Life Is Making Us More Irrational

In “Psych: The Story of the Human Mind,” Paul Bloom, a professor of psychology at the University of Toronto, lays out, in his words, “basically everything I know about the mind.” And when he says “everything,” he means it. Where does consciousness come from? Does IQ matter? What makes us happy? Was Sigmund Freud a madman? The answers to these questions (and more) are all in Paul’s book — and in this episode.
An edited version of Rufus’s interview with Paul first aired in April 2023. Today, we’re bringing you their entire conversation.

Everything Paul Bloom Knows About Psychology

For a long time, Bianca Bosker was not on speaking terms with art. “Going to galleries and museums,” she says on today’s show, “reliably made me feel like I was at least two tattoos and a master’s degree away from figuring out what was going on.” What did art snobs know that she didn’t? Determined to find out, Bianca disowned her normal life and ventured into the underbelly of the art world. She worked at a gallery, as an artist’s assistant, and even as a museum guard. She read the latest research to understand why scientists believe art is as “necessary as food or sex.” And in the end, she learned how to look, really look, at art — a skill she’s now going to share with you.

GET THE PICTURE: Why Bother With Art?

Do you ever feel like your life has become a film loop of the familiar? Maybe you sympathize with the elegiac poet Logan Roy, who said, "Nothing tastes like it used to, does it? Nothing's the same as it was." What lit you up on Monday barely sparks your interest by the weekend. But don't worry, there's nothing wrong with you. You're just experiencing what scientists call habituation, a fancy word for a phenomenon we all face. And the good news is that there's something you can do about it, methods and tools you can use to disrupt familiar patterns, jostle your needle out of its well-worn groove, and refresh the way you see and connect with the people, places, and things in your life. This process is called dishabituation — or, if you prefer, re-sparkling — and neuroscientist Tali Sharot is on the show today to teach you how to do it.

LOOK AGAIN: How to See Your Life With Fresh Eyes

Lots of things go viral on the internet: dumb memes, cat videos, one-pan meals, and celebrity gossip. Why not kindness? That’s the delightful question Chris Anderson, the head of TED, asks in his new book, “Infectious Generosity: The Ultimate Idea Worth Spreading.” He joins Rufus to talk about what he’s learned running the world’s most famous conference, why we’re hardwired to give back, and the small actions we can all take to be a little more generous.
