" The first is that the individual forming part of
a group acquires, solely from numerical considerations,
a sentiment of invincible power which allows him to'
yield to instincts which, had he been alone, he would
perforce have kept under restraint. He will be the
less disposed to check himself from ±he consideration
that, a group being anonymous, and in consequence
irresponsible, the sentiment of responsibility which
always controls individuals disappears entirely. "

― Gustave Le Bon
