Study One: Obedience to Authority According to the Stanley Millgram experiment, individuals who do not mean what their personalities are, in the new and powerful situation, they will obey the circumstances or social contacts under the pressure. The experiment group is around 40 people age 20-50 who will ask questions one the survey and give punishment when the person answers wrong. Of course the punishment voice is output by video and the experiment group do not know about that. When the punishment the electronic shock which from small 15 Volvo to maximum 450 Volvo. Until the 150 Volvo, the voice inside start to scrimping and shouting, while the expert ask them continue to do the punishment. However, after around 350 Volvo, the other side become silence, we observe the reaction of the experiment group. In this study, around 90% people would follow the rules punishment from 15 Volvo to 450 Volvo, even some of them have doubt or suspicion, while some of them are not. The majority of people think that the experts must control the whole program, and believed them loyally. This evidence could explain the World War II, why people are controlled by Hitler in German. Study Two: Critical social psychology The participants are divided by two groups: prisoners and guards in the Phillip Zimbardo’s Stanford Prison Experiment shown on the video. This study want to learn how ordinary man behave when giving them the role of prisoners and guards. The guards whatever the person like it or not, will follow the roles they take, giving orders and prisoners follow them. Some prisoners show unbelieving, but finally they became submissive, dependent and powerless, who also performed stress, anxiety and depression. The role of guards began to displayed some abuse behavior, such as clean the toilet using bare hands. That is why the study had to terminated after 6 days. Professor Zimbardo want to find out not only who you are internally, it is about social contexts which you realize yourself. The experiment examine to see how powerful relations of people played and to see how knowledge situation in the cultural context; it could also be analyze by pursing the role of the individual and society of social groups and to see how people might choices or how social stricture determine the outcome of the events. Study Three: Bystander Revolution/The Bystander effect This study was introduced by the video is a young woman was being stalked and stabbed, many people heard her scrims, but no one came to her aid, not even called the police. Some researchers concluded that one may assume that someone will help, which called diffusion of responsibilities. The more people physically in the emergency situation, the less likely anyone will help. A single person in a emergency, the probability may goes up. The reason explained that when in a group, sometimes even with strangers, you look around and no one is helping, the social norm is do nothing, do not get involved. The video illustrate how do we change the social norms. The moment someone goes help within second is join in, because when you take action, you have bystander effect that someone will help. The summary is constructing a social activeness knowledge, not making us smart, but let us have the awareness of social responsibilities.
