Understanding the Bystander Effect: Factors, Explanations, and Strategies for Intervention.

bystander effect

the finding that a person is less likely to provide help when there are other bystanders

The bystander effect is a social phenomenon that occurs when individuals in a group fail to take action or intervene in a situation where help is needed, assuming that someone else will do so. This effect is particularly strong in situations where the responsibility for intervening is unclear. The bystander effect was first coined after the infamous murder of Kitty Genovese in 1964, where several witnesses did not intervene or alert authorities.

Research has established several factors that may influence the bystander effect, including the size of the group, the presence of other witnesses, the ambiguity of the situation, and the level of personal responsibility that individuals feel. Social psychologists propose several explanations for the phenomenon, including diffusion of responsibility, pluralistic ignorance, and social influence.

Diffusion of responsibility suggests that as the number of bystanders increases, the responsibility of any one individual to act decreases. Pluralistic ignorance refers to the phenomenon where ambiguity or uncertainty about a situation leads individuals to look to others for guidance on how to behave, and if no one else is acting, individuals may assume that there is no need to intervene. Finally, social influence refers to the power of groups to influence individual behavior.

While the bystander effect can have negative consequences, awareness of the phenomenon can help individuals take action in situations where it is needed. One way to overcome the effect is to directly address individuals and give clear instructions on what to do; for example, by asking a specific person to call the police in an emergency. It is also important to promote a sense of responsibility among individuals and to encourage them to take action when help is needed.
