That someone is less likely to help another if other potential helpers are present than otherwise.
The bystander effect is a social psychological phenomenon that refers to cases in which individuals do not offer help to a victim. The probability of help is inversely related to the number of bystanders. In other words, the greater the number of bystanders, the less likely it is that any one of them will help. Several variables help to explain why the bystander effect occurs. These variables include: ambiguity, cohesiveness and diffusion of responsibility.
