Bystander Effect

The Bystander Effect is a social phenomenon in which a person (or persons) are less likely to offer help to another person (or persons) when there are more people around who can also provide assistance. Many people believe that, when there is an emergency and lots of people are present, the people in need are more likely to get assistance. However, this is not the case. Rather, the more people there are who can help, the less likely each person is to offer help. Thus, when in a group, people are less likely to offer help than when they are alone.
