We Fact-Checked 5 Myths You Were Taught in School. Here's What We Found.
Your teachers weren't lying to you. But they were passing on things that were never actually true.
Some of the most confidently repeated "facts" in the world originated in classrooms. They spread because teachers trusted their textbooks, textbooks trusted older textbooks, and nobody stopped to check the original source.
We did. Here's what we found.
───
1. Einstein Failed Math as a Child
The claim: Albert Einstein performed so badly in school — especially in math — that his teachers thought he'd never amount to anything.
Why people believe it: It's the ultimate underdog story. If Einstein failed math, then anyone can be a genius. Motivational posters, TED talks, and self-help books have repeated this for decades.
What the evidence says: Einstein's actual school records tell a completely different story. He consistently earned top marks in mathematics and physics. In the Swiss grading system, 6 is the highest score — the opposite of what most people expect. When his records circulated internationally, readers assumed low numbers meant poor performance. They didn't.
Einstein himself addressed the myth directly: "I never failed in mathematics. Before I was fifteen I had mastered differential and integral calculus."

2. Napoleon Bonaparte Was Unusually Short
The claim: Napoleon was a small man — somewhere around 5'2" — and his aggressive military campaigns were driven by a Napoleon complex to compensate for his height.
Why people believe it: The phrase "Napoleon complex" is now in the dictionary. Countless caricatures depicted him as tiny. It feels like established history.
What the evidence says: Napoleon stood at 5 pieds 2 pouces in French imperial units — which converts to approximately 5'7" in modern measurements. That was perfectly average for a French man in the late 18th century.
The myth has a clear origin: British wartime propaganda. Political cartoonists — particularly James Gillray — deliberately drew Napoleon as a tiny, angry figure to humiliate him during the Napoleonic Wars. The caricature outlived the war by two centuries.

3. Marie Antoinette Said "Let Them Eat Cake"
The claim: When told that French peasants had no bread, Queen Marie Antoinette callously responded: "Let them eat cake" — cementing her reputation as the symbol of royal indifference.
Why people believe it: It's a perfect villain line. Pithy, cruel, memorable. It appears in movies, history classes, and political speeches as shorthand for out-of-touch elites.
What the evidence says: There is no historical record of Marie Antoinette ever saying this. The phrase first appears in Jean-Jacques Rousseau's Confessions — written when Marie Antoinette was approximately 9 years old and still living in Austria. Rousseau attributed it to "a great princess," with no name attached.
By the time the quote was being pinned on Marie Antoinette, it had already been circulating for years with no credible source. She may have been many things, but there's zero evidence she said this.
Verdict: FALSE

4. The Bermuda Triangle Is Unusually Dangerous
The claim: Ships and planes that pass through the Bermuda Triangle disappear at a mysteriously high rate.
Why people believe it: Bestselling books, documentaries, and decades of sensational media coverage built the myth into something that felt like settled geography.
What the evidence says: Lloyd's of London — the world's oldest insurance market — charges standard rates for ships passing through the Bermuda Triangle. If the region were genuinely dangerous, actuaries would know. They don't.
Researcher Lawrence David Kusche went back through the original incident reports and found widespread fabrication, exaggeration, and selective reporting. Ships that disappeared in storms were reported as vanishing in calm waters. The mystery was largely manufactured.
Verdict: FALSE

5. Cleopatra Lived Close to the Time of the Pyramids
The claim: Cleopatra was an ancient Egyptian ruler — meaning she belongs to the same era as the pharaohs who built the Great Pyramids.
Why people believe it: "Ancient Egypt" gets grouped together in our mental timelines. Pyramids, pharaohs, Cleopatra — it all sounds like the same period.
What the evidence says: The numbers are startling. Cleopatra was born in 69 BC. The Great Pyramid was completed around 2560 BC — a gap of roughly 2,500 years. The moon landing was 1969 AD, only ~2,000 years after Cleopatra's death.
Cleopatra was chronologically closer to the moon landing than to the pyramids. She lived in a world that already considered the pyramids ancient history.
Verdict: TRUE (and genuinely surprising)

Why Does This Keep Happening?
These five myths share a common pattern: they spread through authority, not evidence. A teacher repeated what a textbook said. The textbook repeated what an earlier textbook said. And once a myth gets enough repetition, it stops sounding like a claim — it becomes background knowledge.
That's exactly the problem Lenz was built to solve.
