Social psychology is the study of how people influence others' behavior, beliefs, and attitudes. This chapter explored different experiments, stories, and studies that tested how and why humans reacted to situations. A concept that struck me the most is the bystander effect: when one is a part of a group in a situation where someone needs assistance, one is less likely to help because of the presence of other people. An example of this is the violent murder of Kitty Genovese in 1964. She repeatedly screamed out for help for an hour in New York City while being raped, stabbed, and beaten to death, while her neighbors failed to come to her aid. Others assumed that someone else would try to intervene and call 911; this is called a diffusion of responsibility: the reduction in feelings of personal responsibility in the presence of others. The picture below shows how everyone assumes that the person in need doesn't need help or someone else will handle the situation.
