Essentially, individuals of Le Bon's crowd are enslaved to the group's mindset and are capable of conducting the most violent and heroic acts. Le Bon's group-level explanation of behavioral phenomena in crowds inspired further theories regarding collective psychology from Freud, McDougall, Blumer, and Allport. Festinger, Pepitone, and Newcomb revisited Le Bon's ideas in 1952, coining the term deindividuation to describe what happens when persons within a group are not treated as individuals. According to these theorists, whatever attracts each member to a particular group causes them to put more emphasis on the group than on individuals.
