10 jokes, hoaxes and lies that became movements

Every one of these began with a single source: a post, a sign, a letter, a book, a paper or a broadcast. Here is how each one spread, and what it teaches about tracing a claim to where it started.

Jokes that took on a life of their own

1. Birds Aren't Real (2017)

Where it started: Peter McIndoe carried a "Birds Aren't Real" sign at a 2017 protest in Memphis and improvised a backstory about government drones.

How it spread: Rallies, billboards, merchandise and four years in character. In 2022, 60 Minutes reported more than a million followers, and local news had repeated the movement's made-up founding date.

The lesson: Most followers were in on the joke. The claim spread through repetition, not belief. Read the full case, or the origin story with an animated timeline.

2. "Bielefeld doesn't exist" (1994)

Where it started: In May 1994, Achim Held, then a student in Kiel, posted a satirical claim on Usenet that the German city of Bielefeld does not exist. He meant it to mock real conspiracy theories and expected it to last a week or two among friends.

How it spread: It became a fixture of German humor for three decades, picking up add-ons along the way: Bielefeld as a gateway to Atlantis, its university as a disguised spaceship. In 2019 the city offered €1 million to anyone who could prove it doesn't exist. Around 2,000 people entered.

The lesson: A claim built so that no evidence can disprove it survives any evidence. The city's best answer was to make the joke its own. Read the full story, with an animated timeline.

3. The Flying Spaghetti Monster (2005)

Where it started: Physics graduate Bobby Henderson wrote an open letter to the Kansas State Board of Education, which was debating intelligent design in science classes. He demanded equal time for a deity made of pasta.

How it spread: Once he posted the letter online, it drew millions of visits within weeks, and a book followed in 2006. In 2016 New Zealand celebrated its first legally recognized Pastafarian wedding.

The lesson: Satire that copies the form of an argument can win some of the standing of the thing it mocks. Labels matter, and so does what a reader can tell from the source alone. Read the full story, with an animated timeline.

4. Storm Area 51 (2019)

Where it started: In June 2019, Matty Roberts created a joke Facebook event inviting people to storm the military base in Nevada.

How it spread: More than 2 million people clicked "going" and another 1.5 million "interested." Nearby towns and emergency managers prepared for crowds, and Roberts pulled out of a spin-off festival, warning of a possible humanitarian disaster. On the day, about 75 people were at the gate that morning. Estimates for the whole weekend, festivals included, run to about 1,500.

The lesson: An engagement count is not a headcount. Two million clicks turned into a crowd in the hundreds. Read the full story, with an animated timeline.

Pranks that came true

5. The "OK" hand sign (2017)

Where it started: According to the Anti-Defamation League, users of the message board 4chan ran a 2017 prank falsely claiming the gesture stood for "white power." The aim was to bait the media into overreacting to an innocent sign.

How it spread: Some white supremacists then adopted the gesture sincerely. In 2019 the ADL added it to its hate-symbol database, saying the hoax had largely succeeded. It also stresses that most people who make the sign just mean "OK."

The lesson: A false claim can make itself true once people act on it. What the gesture means depends on who is using it and where, so judge each use in its context rather than giving the gesture one meaning. Read the full story, with an animated timeline.

6. QAnon (2017)

Where it started: In October 2017, an anonymous poster on 4chan predicted an arrest that never happened. Researchers note that many users first read it as a LARP: a role-play in which a poster pretends to be a leaking insider, common on the board.

How it spread: Within weeks, two board moderators and a YouTube creator were promoting the posts to wider audiences. Researchers describe the shift from suspected trolling to a movement with near-scriptural texts. Its predictions kept failing, and the movement kept adapting.

The lesson: A missed prediction doesn't end a claim whose followers reinterpret every miss. Log predictions as predictions: each one can be checked once its date passes. Read the full story, with an animated timeline.

Fabrications that became movements

7. The Protocols of the Elders of Zion (1903)

Where it started: An antisemitic forgery, first printed in Russia in 1903, that claimed to be the minutes of a secret Jewish plan for world domination. Much of it was plagiarized from Maurice Joly's 1864 satire of Napoleon III, which had nothing to do with Jews.

How it spread: It was translated across Europe, and in the United States Henry Ford's newspaper repeatedly cited it. In 1921 The Times of London exposed the plagiarism by printing passages side by side with Joly's original. The text still circulates today.

The lesson: The most damaging case on this list began as satire, stripped of its context and given a false author. Comparing a text side by side with its true first source is still the strongest proof, and exposure alone does not stop circulation. Read the full story, with an animated timeline.

8. The MMR–autism paper (1998)

Where it started: A 1998 case series of 12 children in The Lancet, led by Andrew Wakefield, which was publicized as linking the measles, mumps and rubella vaccine to autism.

How it spread: Heavy press coverage followed, and UK vaccination rates fell, a drop blamed for a later resurgence of measles. In 2010 a UK medical tribunal found the research had been carried out dishonestly and irresponsibly, and The Lancet retracted the paper. Multiple large studies have found no link between MMR and autism.

The lesson: A retraction rarely travels as far as the original claim. Trace a scientific claim to the paper, then check what has happened to the paper since. Read the full story, with an animated timeline.

9. The Satanic Panic (1980s)

Where it started: The 1980 book Michelle Remembers, co-written by a psychiatrist and his patient, presented memories of ritual abuse recovered in therapy, a practice that has since been discredited.

How it spread: A publicity campaign, talk shows, and use in training material for police and social workers. Then came the McMartin preschool case, which began in 1983 and ran for seven years in one of the most expensive trials in US history. It ended with no convictions.

The lesson: A claim delivered through an expert carries borrowed authority. Ask what the evidence is, not who is vouching for it. Read the full story, with an animated timeline.

When the story about the reaction is the myth

10. The War of the Worlds "panic" (1938)

Where it started: Orson Welles's radio drama of a Martian invasion aired on October 30, 1938. The false claim that lasted wasn't in the broadcast. It was in the next day's newspapers, which reported nationwide panic.

How it spread: Those reports rested largely on anecdotes and quick wire-service roundups, and newspapers had an interest in painting radio, a rival for news and advertising, as dangerous. Media historians have since found the panic was greatly exaggerated.

The lesson: Sometimes the false claim is the story about how people reacted. Coverage of a reaction is a claim of its own, with its own first source. Read the full story, with an animated timeline.

What the ten cases have in common

• One origin. Every case traces back to a single post, sign, letter, book, paper or broadcast. That is why tracing pays off: correct or label the origin, and the copies lose what they were citing.
• Volume stood in for evidence. Followers, RSVPs and front pages made claims look established. None of them is evidence about the claim. See republication vs. corroboration.
• Context got stripped. Satire turned sincere once it traveled away from its source. That is why TruthRanking attributes each claim to whoever actually published it.
• Authority got borrowed. A medical journal, a psychiatrist, a front-page headline. A verdict rests on the evidence, not the messenger. See our methodology.
• Debunks traveled less far. The Protocols were exposed in 1921 and still circulate. Corrections have to be aimed at the places where the claim actually lives. See correction routes.
• Rebuttals got absorbed. Bielefeld, Birds Aren't Real and QAnon each folded the debunk into the story. A claim built to resist evidence needs its origin documented, not just argued with.
