0:00 A delegation of scientists from Yale University traveled to New York in August of 1835 to get a look at the proof.0:08 The proof of life on the Moon.0:10 This wasn't some fringe belief; it was the story everyone was talking about, and it reminds me of what we saw with the Dancing Plague in Strasbourg.0:22 Remember that?0:23 A contagious physical frenzy.0:25 Well, it turns out a contagious idea can spread just as fast, and you don't even have to leave your house.0:33 So.0:33 Here's the setup.0:34 The New York Sun was a new kind of paper — a penny press.0:39 Cheap, sold on the street, and desperate for readers.0:43 They needed a hit.0:44 On August twenty-fifth, 1835, they published the first of six articles that supposedly reprinted a discovery from the Edinburgh Journal of Science.0:55 The source?0:56 The world-famous astronomer Sir John Herschel, who had allegedly built a telescope of IMMENSE power in South Africa.1:05 A telescope so powerful it could see objects on the lunar surface as if they were a hundred yards away.1:13 The first articles were just a tease.1:15 New species of plants.1:17 A beach of pristine white sand.1:19 Then they saw animals.1:21 First, something like a bison, but with a fleshy veil over its face to protect it from the light.1:28 Okay.1:29 Then, blue unicorns.1:30 Seriously.1:31 The article describes them as looking like goats, but with a single horn.1:37 The city ate it up.1:38 The Sun's circulation exploded.1:40 Everyone wanted to know what Herschel saw next.1:44 And then came the big one.1:46 The final installment.1:47 Through the lens of this fantastical telescope, they saw them.1:52 Humanoids.1:53 Beings that walked upright, with copper-colored hair and...1:57 wings.1:58 They were described in incredible detail, these "Vespertilio-homo," or bat-men.2:04 The paper reported they were innocent and happy, gathering in groups, gesturing to each other.2:11 The public went absolutely wild.2:13 People weren't just reading it; they were BELIEVING it.2:18 This is when the Yale scientists packed their bags.2:21 Religious groups started taking up collections to send missionaries to the moon.2:27 For five weeks, the Great Moon Hoax was the biggest story in the world.2:33 So, where have we seen this before?2:35 It’s almost too easy, right?2:38 You hear "viral misinformation" and you immediately think of Facebook memes or deepfakes on Twitter.2:45 And yes, the pattern is there.2:47 A story that’s too good to check, feeding a deep-seated desire for wonder, or for confirming a bias.2:55 The New York Sun needed circulation numbers; today's algorithms need engagement.3:01 The economic incentive is EXACTLY the same.3:04 But here’s where the analogy gets tricky, and where it really tells you something.3:10 The Great Moon Hoax eventually collapsed under its own weight.3:15 The author, Richard Adams Locke, a reporter for the Sun, later admitted it was a satire meant to mock speculative science.3:24 But the Sun itself?3:26 It never issued a retraction.3:28 Not once.3:29 It just...3:29 let the story fade.3:31 And its circulation, which had skyrocketed, never went back down.3:36 They got what they wanted.3:38 Today, the speed is different.3:40 A hoax like that would be debunked on social media in hours, if not minutes.3:46 The real Sir John Herschel, who was totally unaware of any of this in South Africa, would have his agent issue a statement.3:55 The debunking would itself go viral.3:58 But here’s the problem.4:00 The debunking never reaches everyone who saw the original lie.4:04 The correction is always playing catch-up to a story that was more fun to believe.4:10 We think we're more sophisticated now, with our fact-checkers and our digital literacy.4:17 But the Moon Hoax shows that the vulnerability isn't in our technology.4:22 It’s in our appetite.4:24 We want to believe in the unbelievable.4:27 We want to think someone has a telescope powerful enough to show us a universe more magical than our own.4:35 The Sun didn't sell people a lie.4:37 It sold them a sense of wonder for a penny.4:41 And that business model has never gone out of style.
