Famous hoaxes have fooled millions for centuries. In 1184, a “letter of doom” spread panic, convincing Europeans the world would end in 1186. This warning was adapted for centuries, showing how fear is often exploited.
By the 1800s, spirit photographers like William H. Mumler sold fake portraits of dead loved ones. They earned trust through emotional appeal.
Convincing frauds have shaped history. Medieval churches displayed Jesus’ foreskin relics, claiming over 20 had this sacred item. This attracted pilgrims and wealth.
Even Michelangelo was linked to the Laocoön statue, a Renaissance forgery passed off as ancient art. These tricks show how greed and belief can turn lies into legends.
Today, the Bruce Museum’s Monsters and Mermaids exhibit tells these stories until February 11, 2024. From the Cardiff Giant’s gypsum “giant” to Piltdown Man’s fake bones, these tales show hoaxes thrive where doubt fades. Explore how greed, faith, and curiosity let these deceptions endure.
Introduction to Famous Hoaxes
Hoaxes have always fascinated people, mixing creativity with trickery. The 1938 War of the Worlds radio show and the 1869 Cardiff Giant statue are great examples. They fooled many by playing on hoax psychology, using our curiosity and trust in those in power.
“To draw attention to your fraudulent skills. To gain financial benefits through deceit. Sociopathological hoaxers target others to discredit them. It’s fun to fool people.”
Hoaxes have many reasons behind them. The 2009 Balloon Boy incident, for example, cost taxpayers $47,000. The Piltdown Man fraud misled scientists for years, seeking profit. Even online, like the 2017 Hurricane Harvey shark photo, which was shared 84,000 times, shows how fast lies spread.
Our tendency to believe what we want to believe and trust authority makes us easy targets. From fake moon landings in 1835 to the 2015 Area 51 autopsy hoax, these tricks show our timeless weaknesses. Each hoax teaches us why they continue to happen, setting the stage for the famous cases to come.
The Great Moon Hoax of 1835
In 1835, the New York Sun amazed readers with a six-part series called “Discoveries in the Moon.” The moon hoax 1835 said astronomer Sir John Herschel found forests, oceans, and strange creatures on the moon. It talked about vespertilio-homo—bat-winged humans—and unicorns.
These newspaper hoaxes pretended to be from the Edinburgh Courant. They used a fake “Dr. Andrew Grant” and a 24-foot telescope. Richard Adams Locke, the real writer, mixed real science with fantasy.

People loved the stories. Religious groups wanted to go to the moon. But skeptics had a hard time proving it was false.
The New York Sun sold more papers than ever. Even when it was revealed as a lie months later, the paper didn’t say sorry. Edgar Allan Poe thought Locke stole from his story, “Hans Pfaall,” but they never went to court.
Why did the moon hoax 1835 work? People back then loved to dream about science. Figures like Reverend Thomas Dick said billions lived on the moon. This scientific deception showed how media can choose excitement over truth.
Today, we see this pattern in viral lies. The hoax is a key moment in media history. It shows how our desire for wonder and excitement can make us forget what’s real.
The Cardiff Giant: A Giant Misunderstanding
In 1869, a 10-foot stone figure called the “petrified man” sparked a huge fuss. George Hull, a tobacconist, planned the Cardiff Giant hoax. He wanted to prove the existence of giants from the Bible. He buried a gypsum statue on his cousin’s farm, waiting for people to find it.
When workers found the 2,990-pound statue near Cardiff, New York, many came to see it. People paid 50 cents to see the petrified man. The American hoaxes legend grew as it was shown across the country, making Hull over $20,000.
There’s a sucker born every minute.
Showman P.T. Barnum tried to buy the Cardiff Giant but failed. He made a fake one and said it was real. But scientists soon found out it was a hoax. The Chicago Tribune exposed it in 1870, but the joke had already spread far.
Even though it was found out, the Cardiff Giant became famous. It teaches us about the dangers of greed and believing too easily. Today, it’s in a New York museum, reminding us of the Cardiff Giant hoax’s impact.
Piltdown Man: The Greatest Scientific Hoax
In 1912, the Piltdown Man hoax rocked the scientific world. It claimed a 500,000-year-old human ancestor was found. Charles Dawson, an amateur collector, was behind it. He mixed a modern human skull with an orangutan’s jaw.
He stained the fake fossils and buried them in gravel. This trick fooled experts for 41 years. Dawson even filed teeth with a metal tool to look old, a detail found decades later.

Charles Dawson’s archaeological hoaxes went beyond Piltdown. By 1916, he had 38 other fake finds, like the “Bexhill Hippo,” a fake elephant tooth. Scientists were eager to find a “missing link” in Britain, like those in Africa.
When the hoax was exposed in 1953, tests showed the jaw was from a modern ape. The skull was from medieval times. Fluorine tests showed the bones were not the same age.
“The Piltdown fragments may not be as old as claimed,” warned paleontologist William King Gregory in 1914. His doubts were ignored until 1953, when tests confirmed his suspicion.
This fraud wasted decades of research. It delayed the acceptance of Africa’s role in human evolution. Dawson’s story teaches us that scientific frauds can happen when ambition meets complacency.
Today, the Piltdown saga teaches researchers to always question evidence. A 1953 headline summed it up: “Fossil Hoax Makes Monkeys Out of Scientists!”—a lesson for today’s science.
The Left-Handed Whopper: A Marketing Trick
In 1998, Burger King pulled off a clever Left-Handed Whopper campaign. They said the burger was made for left-handed folks by flipping its ingredients 180 degrees. Ads in USA Today explained this “scientific” twist, even mentioning mirrored ketchup bottles. It was all a joke for April Fools’ Day.
But, it worked. People really wanted the Left-Handed Whopper. Others joked about needing a “right-handed” version. This prank showed how corporate hoaxes can turn silly ideas into big hits.
Burger King’s marketing pranks weren’t the first to mix truth and humor. Taco Bell’s fake “purchase of the Liberty Bell” in 1996 fooled many too. Both campaigns proved that playful lies can make a brand buzz.
The Left-Handed Whopper’s success came from its detailed, satirical approach. Critics said it was a waste, but the free publicity was huge. It showed that even wild ideas can grab attention.
Today, brands use hoaxes to get noticed. The 1998 stunt was cheap but got lots of press. It proved that serious-looking jokes can fool people. Burger King’s goal wasn’t to trick forever—it was to start a conversation. The Left-Handed Whopper ads made the brand more visible. A clever lesson: sometimes, the best marketing is fake.
The War of the Worlds Radio Broadcast
On October 30, 1938, a War of the Worlds broadcast by Orson Welles turned a story into chaos. The Mercury Theatre’s 60-minute drama, seen as live news, fooled many. Over 32 million Americans listened, but few knew it was a play until it was too late.
Panic spread as actors talked about “-Martian tripods” attacking New Jersey. Radio panic went from coast to coast.
Those who missed the disclaimer thought Martians had invaded. Emergency calls poured in, and churches were filled with scared people. The Orson Welles hoax became famous, but studies showed much of the fear was overblown.
Only 2% of listeners started from the beginning. Many thought the drama was real.
The FCC looked into the Mercury Theatre but found no fault. Though no one was hurt, it changed media rules. The War of the Worlds broadcast is a key moment in media history. It shows how radio’s live feel can blur truth and fiction.
The Balloon Boy Incident
In October 2009, a Balloon Boy hoax shocked the nation. Richard and Mayumi Heene said their son Falcon was in a homemade helium balloon. The balloon, 20 feet wide, flew 7,000 feet high in Colorado.
Media and emergency teams rushed to the scene. They watched the balloon on TV for 90 minutes. But when it landed, Falcon was found safe in his attic, revealing the hoax.
The family had a history of reality TV stunts. They wanted fame. The rescue cost over $40,000. Richard Heene faced felony charges, and Mayumi pleaded guilty to a misdemeanor.
They both got jail time and fines. They were also banned from making money from the hoax for years.
Experts said the media’s quick coverage was media manipulation. It turned the story into a spectacle. The balloon could lift 65 pounds, enough for Falcon.
But the real goal was to get attention. After the scandal, the family moved to Florida. The incident changed how news outlets handle unverified claims.
D.B. Cooper: The Mystery that Remains
On November 24, 1971, a man named Dan Cooper hijacked Northwest Orient Flight 305. He demanded $200,000 and parachutes. After getting the money, he jumped from the plane at 10,000 feet and disappeared into the Pacific Northwest.
The FBI worked on this case for 45 years. But they never found out who Cooper was or if he survived. This makes it one of America’s most famous unsolved crimes.
“Every clue we uncover just creates more questions.”

In 2016, the FBI closed the case after looking at over 1,000 leads. But people online keep coming up with new theories. They found 66 fingerprints and 19 pounds of cash, but they didn’t lead anywhere.
Even a parachute found near the Columbia River in 2008 didn’t prove Cooper survived. His calm behavior during the flight made the D.B. Cooper mystery even more intriguing. It’s a mix of a daring crime and a modern-day legend.
Today, fans of “Cooperology” search the forests and online forums. YouTube channels like Dan Gryder’s (100k+ subscribers) also dive into the clues. The FBI’s 2016 decision to close the case hasn’t stopped people from wondering.
Was Cooper acting alone, or was it a staged event? With no body found and $20 bills turning up decades later, the case remains a mystery. The $200,000, parachutes, and the man who vanished midair keep the mystery alive for new generations.
The Loch Ness Monster: Truth or Myth?
In 1934, the Surgeon’s Photograph became famous. Colonel Robert Wilson said he took it, sparking worldwide interest. But in 1994, Christian Spurling revealed it was a toy submarine with a plastic head. This hoax is one of history’s most lasting mysteries.
Many believe in the Loch Ness Monster, despite doubts from scientists. Over 1,155 sightings have happened, but no proof has been found. Studies show Loch Ness doesn’t have enough fish for big creatures, and its cold water doesn’t support plesiosaurs.
No bones or DNA evidence has been found, even after years of searching. The myth lives on because of our curiosity and the money it brings to Scotland. Even when experts say there’s no truth, the legend continues. The Loch Ness Monster shows how stories can last long after they’re debunked.
Momo: The Scare of a Modern Generation
In late 2018, the Momo challenge hoax spread like wildfire online, causing a global online moral panic. It started with a scary sculpture by Japanese artist Keisuke Aiso, wrongly linked to a “challenge” that could harm kids. Despite no real harm, the internet urban legends quickly spread on WhatsApp and social media. A warning tweet got 22,000+ retweets, and celebrities like Kim Kardashian helped spread the fear with her 129 million Instagram followers.

Later, fact-checkers found no real cases of suicides linked to the challenge. Yet, schools and police warned about it, just like with the Blue Whale challenge. YouTube stopped making money from Momo-related videos, showing the platform’s struggle to keep disturbing content away from kids. A Wired report showed pedophiles sneaking into kids’ content, leading advertisers to leave YouTube.
YouTube’s ecosystem is rife with disturbing content aimed at kids, often using popular characters to lure viewers.
Experts say this panic shows deep worries about screen time and internet safety. A 2016 study found 60% of teens create accounts without their parents’ knowledge, while only 13% think parents get their online lives. This gap leads to myths becoming real fears. The Momo case shows how online moral panics mix real fears with exaggerated rumors.
YouTube Kids is getting more criticism for not doing enough to keep content safe. This is different from networks like Nickelodeon, which are more regulated. The Momo story warns us about how fear can spread faster than facts in today’s digital world.
Conclusion: The Lasting Impact of Hoaxes
Hoaxes have been around for centuries, showing us that people often believe what they hope or fear. The Great Moon Hoax of 1835 and the Cardiff Giant are just a few examples. They show how misinformation psychology shapes what we believe, whether through old newspapers or social media today.
Every hoax teaches us about media literacy. The 1874 fake zoo attack story, for instance, caused panic but was later revealed as false. It shows how important context is. Today, with AI and viral trends, it’s harder to spot lies. But history teaches us to question sources and look for evidence.
Academic hoaxes, like the 1996 Sokal Affair, remind us that even experts can be fooled. Yet, research shows we naturally judge information based on its plausibility and trustworthiness. This means we need to stay alert, whether checking a viral post or a scientific study. The key is to be skeptical but also curious.
Hoaxes are more than just funny stories; they reflect our nature. By studying them, we learn to recognize our own biases and those of others. As misinformation changes, so must our ways to fight it. The past teaches us that finding truth takes effort, but it’s worth it for trust in science, news, and each other.
