How do Mobs form?

Answer 1

I recommend an older work on this topic; "The Crowd" by Gustave le Bon. He, like others since, postulate that a mob forms around a person or a singular event (in much the same way as a particle in a super-cold solution can make it harden instantly) which causes the formation of the mob. The mob follows it's own rules (like all chaotic 'systems') and they are almost never the rules of the individuals making up the group.

Answer 2

Mobs can form through a variety of mechanisms, such as social influence, emotional contagion, or a shared sense of identity or grievance. Factors like anonymity, conformity, and deindividuation can also play a role in mob formation, leading individuals to act in ways they might not typically behave when part of a larger group.
