Everyone has heard an urban legend, usually from someone who swears it happened to a friend of a friend. They’re modern folklore: short, scary, plausible stories that travel from person to person and change a little with each telling. Here’s where some of the most famous ones came from, and why they stick.

What makes a story an urban legend

Folklorists use the term for stories told as true, set in the recent past and in familiar places, usually attributed to a vague source: a cousin’s coworker, a friend of a friend. Folklorist Jan Harold Brunvand helped popularize the term with his 1981 book The Vanishing Hitchhiker.

Poisoned Halloween CandyStrangers hide poison or sharp objects in trick-or-treat candyHarm to children from outsiders

Where they came from

Many legends are older than they seem. Versions of the vanishing hitchhiker were being told long before cars, with ghostly travelers on horseback or in carriages. The alligator legend got a boost from real newspaper reports of stray alligators found in New York in the 1930s, though no sewer colony has ever been documented.

Poisoned candy is one of the most widely feared, and least supported. Sociologist Joel Best studied decades of reports and found no confirmed cases of strangers randomly poisoning children’s Halloween treats. The rare real cases usually involved someone the child knew.

Why urban legends spread

  • They feel true. Everyday settings and a named, if distant, source make them believable, the same techniques used in our creepy stories that feel true.
  • They carry warnings. Don’t pick up strangers, lock your car, look after the children.
  • They track our anxieties. New technology gets new legends, from chain emails to viral posts.
  • They’re fun to tell. A good legend has a twist ending made for campfires and sleepovers.

Panic stories can grow in the retelling, too. Famous Controversies explains how the story of mass hysteria over the 1938 War of the Worlds broadcast was greatly exaggerated.

Using legends in your own stories
