Hank Green is one of the most beloved science creators on the interwebs. He’s been making videos for almost 20 years, spanning LOTS of eras of the Internet, from YouTube prank videos to TikTok dance challenges to AI slop. In this episode, Wendy sits down with Hank to talk about this wild ride. They reminisce about his path to YouTube stardom, and they’ll pull back the curtain on social media algorithms — how they’ve changed, and the sneaky ways they draw us in. And while Hank has been publicly fighting off internet trolls, he’s also been dealing with his own personal battle with cancer. He takes us through what’s changed for him since he got diagnosed, and the science he learned about pee and chemotherapy along the way.

Lots of people are using science to say that free will is a trick of the mind, that whether or not you listen to this episode, or eat a taco, or do a silly dance right now — it’s all predestined. But do we really have science receipts for that? We find out by talking to neuroscientist Prof. John-Dylan Haynes and theoretical physicist Prof. Sean Carroll.

It’s like narcissism is oozing out of our celebrities, politicians, partners, parents, maybe even ourselves??
