In history, people have committed heinous acts like witch trials and executions based on superstitions.

Additionally, practices like human sacrifice in ancient civilizations were often driven by superstitious beliefs.

Way back in early societies, people used superstitions to explain things that they couldn't understand.
Superstitions always try to explain things that people don't understand or know about. In the 1980's urban superstitions included flying saucers, and alligators living in sewers. Sometimes the new superstitions reflect the fears of people about the world they live in. Misinformation also contributes to superstitions.
