0:00 On August twenty-fifth, 1835, the world learned about man-bats living on the moon.0:05 Not as a joke, but as a scientific fact reported in New York’s most popular newspaper.0:12 Last time, in episode fifty-nine, we saw how an entire army could destroy itself at Karánsebes through a tragic, almost comical, misunderstanding.0:22 Today, the chaos isn't accidental.0:25 It’s manufactured, sold for a penny on a street corner, and it reveals something fundamental about how we believe what we believe.0:34 The story starts with The New York Sun, a new paper trying to make a name for itself.0:40 And they came up with a brilliant plan.0:43 They published a six-part series claiming that the famous astronomer Sir John Herschel—a real, respected scientist—had built a revolutionary new telescope in South Africa.0:55 A telescope so powerful, it used what they called "hydro-oxygen" illumination to project an image of the lunar surface onto a wall, like a movie screen.1:06 They claimed he could see objects just eighteen inches across.1:11 From two hundred and forty thousand miles away.1:14 And what did he see?1:16 At first, it was just geography.1:18 Fields of poppies, vast forests, oceans of sapphire blue.1:22 Then, the animals appeared.1:24 First, herds of what looked like...1:27 brown unicorns.1:28 Then, bipedal beavers that lived in huts, carried their young, and had discovered the use of fire.1:35 I know.1:35 It sounds completely insane now.1:37 But the articles were written with such dry, scientific precision, filled with technical jargon and plausible-sounding details, that people were hooked.1:48 Rival newspapers, desperate not to be scooped, just reprinted the Sun’s articles verbatim.1:55 Then came the big reveal.1:57 Part four of the series.1:58 Herschel supposedly focuses his lens on a new region and sees them.2:03 Winged humanoids.2:05 Vespertilio-homo, the articles called them.2:08 Man-bats.2:08 They were described as being about four feet tall, covered in short, glossy, copper-colored hair, with wings like a bat’s stretching from their shoulders to their legs.2:20 The articles reported, with serene confidence, that these creatures were "innocent and happy," spending their days collecting fruit and bathing in rivers.2:32 And New York… and then America… and then the world, lost its mind.2:36 The Sun’s circulation exploded, making it the most-read paper on the planet.2:42 A group of women in Springfield, Massachusetts, reportedly started a collection to raise money to send missionaries to the moon to convert the man-bats.2:53 Scientists at Yale University were so convinced they sent a delegation to New York to try and see the original source material from Herschel.3:03 The problem was, you couldn't just call up South Africa in 1835.3:08 Disproving the story would take weeks, even months.3:11 And in that information vacuum, the lie flourished.3:15 So where have we seen this before?3:17 This is the part that gets me.3:20 The Great Moon Hoax is the perfect nineteenth-century blueprint for modern viral misinformation.3:26 The New York Sun was a penny press paper—it was cheap, it was for the masses, and its business model depended entirely on capturing attention.3:37 It was the social media feed of its day.3:40 The incentive structure is identical: create the most outrageous, engaging content possible, and watch the clicks—or in their case, the pennies—roll in.3:51 The analogy holds up.3:52 They used a trusted authority, Sir John Herschel, as a shield for their fiction, the same way a modern deepfake might put false words in a real person’s mouth.4:04 They relied on the slow speed of fact-checking.4:07 By the time anyone could definitively prove it was a lie, the paper had already won.4:13 Its circulation was permanently higher.4:16 But here’s where the analogy breaks.4:18 The hoax was eventually exposed, not with a bang, but a whimper.4:23 The author, a reporter named Richard Adams Locke, eventually admitted it to a friend, and the story trickled out.4:31 The Sun never printed a retraction.4:34 They didn't have to.4:35 They just let the story fade and enjoyed their new status as the world’s biggest newspaper.4:42 There was no accountability.4:44 Not really.4:45 The most incredible discovery of 1835 wasn't unicorns or winged humanoids on the moon.4:51 It was the discovery of a new, powerful, and terrifying force on Earth: a mass media that could, for a price, convince the public of anything, and a public that was, perhaps, more willing to be fooled than anyone had ever imagined.
