What is the Bystander Effect?

The Bystander Effect refers to the social psychological phenomenon where the presence of other people discourages an individual from intervening in an emergency situation. Specifically, as the number of bystanders increases, the likelihood that any one individual will help decreases. This decline in helping behavior can be attributed to a diffusion of responsibility; individuals in a group may feel less personal responsibility to act because they believe someone else will take action or because they look to others for cues on how to behave.

This concept is supported by research demonstrating that people are less likely to respond to emergencies when they are in a crowd compared to when they are alone. In situations with multiple witnesses, individuals may assume that someone else is more qualified to intervene or that someone else will take the initiative, leading to inaction.

For example, the idea that everyone rushes to help contradicts the basic premise of the phenomenon, while assuming bystanders feel more responsible misrepresents the dynamic of shared responsibility that actually contributes to the reduction in individual action.
