DeﬁnitionThe phenomenon in which the greater the number of peoplepresent, the less likely people are to help a person indistress. People are more likely to help when there are fewto no other witnesses.
How does it work?First, a bystander will notice the event, andtake note of the events that are transpiring.Second, a bystander will realize that there isan emergency.Third, a bystander will either assumeresponsibility, or assume that other bystanders will assume responsibility for the situation.Fourth, a bystander will either recognize that they have the knowledge to help the situation, oracknowledge that they do not know enough to be helpful.Fifth, a bystander will either act to help the situation, or simply remain an observer.
