Aggression
Some scholars believe that behaviors like aggression may be partially learned by watching and imitating people's behavior, while other researchers have concluded that the media may have some small effects on aggression. There is also research questioning this view. For instance, a long-term outcome study of youth found no long-term relationship between playing violent video games and youth violence or bullying. One study suggested there is a smaller effect of violent video games on aggression than has been found with television violence on aggression. This effect is positively associated with type of game violence and negatively associated to time spent playing the games. The author concluded that insufficient evidence exists to link video game violence with aggression. However, another study suggested links to aggressive behavior.
Obedience (human behavior)
The Milgram study found that most participants would obey orders even when obedience posed severe harm to others. With encouragement from a perceived authority figure, about two-thirds of the participants were willing to administer the highest level of shock to the learner. This result was surprising to Milgram because he thought that "subjects have learned from childhood that it is a fundamental breach of moral conduct to hurt another person against his will". Milgram attempted to explain how ordinary people were capable of performing potentially lethal acts against other human beings by suggesting that participants may have entered into an agentic state, where they allowed the authority figure to take responsibility for their own actions.
