Frequently Asked Questions
What was the Kitty Genovese case that led to the discovery of the bystander effect?
In 1964, Kitty Genovese was murdered outside her apartment building in Queens, New York. Initial reports claimed that 38 witnesses heard her cries for help but failed to intervene or call police. This case became the catalyst for psychologists to study why people are less likely to help in emergencies when others are present.
What psychological experiments were conducted to test the bystander effect?
Social psychologists John Darley and Bibb Latané conducted controlled experiments in the late 1960s to study bystander behavior. In one famous study, participants heard someone having what seemed like a seizure over an intercom. The researchers found that people were less likely to seek help when they believed other bystanders were also present.
How does the bystander effect explain why people don't help in emergencies?
The bystander effect occurs when individuals are less likely to offer help in an emergency when other people are present. This happens due to diffusion of responsibility, where people assume someone else will act, and pluralistic ignorance, where people look to others for cues and misinterpret inaction as a sign that help isn't needed.
