The Lucifer Effect written by Philp Zimbardo was created to help people understand how good people become bad. The book begins by explaining what the Lucifer Effect actually is in biblical twists and turns, then goes on to explain what happened during Zimbardo's experiment in Stanford Prison. Lucifer "The Morning Star" was God's most trusted angel until he challenged God's authority. When Lucifer challenged God's authority, he was thrown into hell, becoming Satan. It was the ultimate transformation from good to evil. The Stanford Prison Experiment (SPE) was designed to test what makes good people do bad things. In order to begin the experiment, Philp and his research team had to resolve a few issues before they began. First, they needed a controlled space where they could monitor prisoners and guards without interruption. The solution was the basement of Stanford's psychology department. The research team spent several days creating a simulation. First, most people are moral creatures most of the time, but sometimes people do the wrong thing. According to Zimbardo, “evil is knowing better, but doing worse.” This means that ordinary people act in accordance with society by obeying the standards that have been imposed on them. However, sometimes people violate these standards. Second, people are moral creatures until they gain power. Power changes people, for example, the guards were normal, nice guys, but once they were given the power that being a guard gives them, they changed. They became violent people whose goal was to humiliate and embarrass the prisoner. Finally, situational factors can cause people to change. An example of this is the factors that led to the change of guards. The guards wanted to keep order in the prison and at first the prisoners didn't want to obey them, so the guards became meaner, thus leading the prisoners to eventually obey orders.
