They followed theories of cognitive psychology and frustration-aggression theory and saw the cause of revolution in the state of mind of the masses, and while they varied in their approach as to what exactly caused the people to revolt (e.g., modernization, recession, or discrimination), they agreed that the primary cause for revolution was the widespread frustration with socio-political situation.
