    1. 1. Bystander Effect by Evan Franz
    2. 2. Intro
    3. 3. 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.
    4. 4. 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.
    5. 5. ExamplesIn 1964, 28-year-old Catherine Genovese was attacked andstabbed on the way home from work. Even from repeatedcries for help, none of the 20 or so people in the apartmentbuilding called the police or went to help. 30 minutes passedbefore the police were contacted.
    6. 6. ExamplesIn China, 2-year-old girl Yueyue crushed by two vans andleft for dead by nearly 20 passer-by.
