The Bystander Effect
Captions available
The idea
The bystander effect is the reduced likelihood that any individual will help when others are present.
In practice
A person collapsing in a crowded station waits longer for assistance than one on a quiet street.
Where people slip
Later field studies find help is often given in groups. The effect is real and smaller than its reputation.
