Popular beliefs that don't hold up, and what is actually true. Every myth is debunked in a 2-minute article.
Myth
Millions of people were executed as witches
Actually
Historians' estimates based on documents put the number executed at several tens of thousands over three centuries. The figures in the millions that are often repeated come from 19th-century polemics and are not supported by archival evidence.
Authorities lit the fires, but someone living nearby started the case. An accusation grew not from theology but from a refused request, a long-running feud, and the need to explain why disaster struck a household.
The Inquisition was a court not for acts, but for belief - and only over baptized people. The most common charge was not "witch," but "said too much": a joke about saints, a doubt voiced aloud, an argument over cards. The stake was the rare peak of a long ladder of punishments.
Witch hunts ended when people stopped believing in witchcraft
Actually
The trials ended not because people stopped believing in witchcraft, but because the rules of evidence changed. Once courts stopped accepting confessions extracted under torture and testimony about visions, there was no longer any way to substantiate the accusations.
The Malleus Maleficarum was the church's official witch-hunting manual
Actually
It was a guide to identifying and condemning witches, published in the late 15th century. The church never officially accepted it and condemned it in some places, but the printing press helped it spread more widely than any official document.
Most enslaved Africans ended up on US cotton plantations
Actually
The Atlantic slave trade lasted roughly three and a half centuries. Not because no one noticed it: it was built like a machine that kept renewing its own demand and spread the profits among too many people for any one person to shut it down. And it did not end because it stopped paying.
Banning the slave trade and abolishing slavery itself were different events, separated by decades. In between, the slave trade continued illegally, and after abolition, plantations adopted another system of coercion that was not formally called slavery.
The major famines of recent centuries usually happened when warehouses were not empty. Food was available somewhere in the country, in a neighboring region, or on ships in port. What was missing was not food, but access to it.
Droughts and crop failures happen often, but mass famine is rare. The difference is almost always who can buy or get food when there is less of it. So famine is more about prices, roads, and government decisions than weather.
The weight lost in the first days without food is fat
Actually
Without food, your body does not shut down - it switches fuels in turn: first sugar from the liver, then fat. All the while, it tries not to touch your muscles or brain. Weakness, feeling cold, and intrusive thoughts about food are not a lack of willpower, but precise saving.
The more witnesses there are, the more likely someone will help
Actually
Witnesses' silence is often blamed on cowardice, but research points to something else: the more people are around, the less likely it is that any one person will step in. Everyone sees that the others are calm and concludes that there is no need to intervene.
Innocent people never confess to crimes they didn't commit
Actually
A confession is considered the strongest evidence, so investigators pursue it. But innocent people confess more often than you might think: in cases where the real culprit was later found, a false confession appears in about a quarter of them.
Darwin's On the Origin of Species was banned by the Vatican
Actually
Lists of banned books read like a catalog of dangerous ideas. But really, they are a snapshot of a particular authority's fears in a particular year: the same book has been banned for being crude and for being offensive - for opposite reasons.
Borders that still cut across maps in straight lines were drawn by people who had never been there. Weapons decided who could hold land on the ground, but maps followed another rule: a territory was considered yours if neighboring powers recognized your claim. The consent of the people living on that land was not part of the process.
