Human behaviors in groups is what you are talking about. The behavior of the collective is different than the behavior of the individual. Just about anything you look at is different when viewed from different perspectives. It is the old spotlight vs. floodlight scenario where you see different aspects of the same picture when viewed at the macro (collective) and micro (individual) level. You should google "group behavior of human beings" in general. I'm sure most people on the forum already know my loathing of humanity based upon its collective behaviors, so I'll spare you all.
