Addresses crowd behavior, authority, resistance. The "we"concept and how crises lead to people coming together, shifting from the "me" to the "we" which makes the boundaries of the "we" very important. Also, considering influence within groups/crowds and authority "leadership should be seen as a group process, where the leader influences us by telling us who we are..."  "conditions where people are less likely to obey tend to be ones where the authority figure is less legitimate and you’re less likely to identify with [them]...so the point is this, people don’t commit harm because they’re unaware of it. They’re perfectly aware of it. Eichmann was perfectly aware of the fact he was deporting people to Auschwitz to die. No, it’s because you are persuaded that what you are doing serves the greater good."
