The salem witch trials were an example of mass hysteria because everyone was afraid of witchcraft so much that they were ready to indict anyone and pursue anyone. Similar to this was the communist hunt in the fifties and sixties where everyone was afraid that people were secretly working for the Soviets and they were prepared to indict anyone.
