it would appear the personality types of the population split into 20/80 individualist/collectivist. the 80% of people are more or less herd animals. even if you explain what happened to them, and they are able to overcome cognitive dissonance and believe you, they would rather sit and die quietly then have to come up with their own solution or lead. the 20% are too individualist to cooperate with each other, even though they do have sufficient numbers to make a stand. get 100 of the 20% together and you'll get 101 different ideas on what to do.  it would seem that revolutions are triggered by individualists gathering enough herd collectivists to follow them. since the system is so good at censorship and herding, this won't be allowed to happen. god is the only one that will save humanity from itself.
