Over the past five years TikTok has radically changed the online world. But trust us when we say, it’s not how you’d expect.
Today we continue our yearslong exploration of what you can and can’t post online. We look at how Facebook’s approach to free speech has evolved since Trump’s victory. How TikTok upended everything we see. And what all this means for the future of our political and digital lives.
Special thanks to Kate Klonick

Creation Story
October 10, 2025
•34m
Ella al-Shamahi is one part Charles Darwin, one part Indiana Jones. She braves war zones and pirate-infested waters to collect fossils from prehistoric caves, fossils that help us understand the origin of our species. Her recent hit BBC / PBS series Human follows her around the globe trying to piece together the unlikely story of how early humans conquered the world. But Ella’s own origins as an evolutionary biologist are equally unlikely. She sits down with us and tells us a story she has rarely shared publicly, about how she came to believe in evolution, and how much that belief cost her.
Special thanks to Misha Euceph, Khalil Andani, and Hamza Syed.

What Up Holmes?
October 24, 2025
•35m
Love it or hate it, the freedom to say obnoxious and subversive things is the quintessence of what makes America America. But our say-almost-anything approach to free speech is actually relatively recent, and you can trace it back to one guy: a Supreme Court justice named Oliver Wendell Holmes. Even weirder, you can trace it back to one seemingly ordinary eight-month period in Holmes’s life when he seems to have done a logical U-turn on what should be say-able. Why he changed his mind during those eight months is one of the greatest mysteries in the history of the Supreme Court. (Spoiler: the answer involves anarchists, a house of truth, and a cry for help from a dear friend.) Join us in an episode we originally released in 2021, as we investigate why he changed his mind, how that made the country change its mind, and whether it’s now time to change our minds again.
Special thanks to Jenny Lawton, Soren Shade, Kelsey Padgett, Mahyad Tousi and Soroush Vosughi.
