“The public cannot comprehend this weapon, and therefore cannot believe that they are being attacked and subdued by a weapon.
The public might instinctively feel that something is wrong, but that is because of the technical nature of the silent weapon, they cannot express their feeling in a rational way, or handle the problem with intelligence. Therefore, they do not know how to cry for help, and do not know how to associate with others to defend themselves against it.
When a silent weapon is applied gradually, the public adjusts/adapts to its presence and learns to tolerate its encroachment on their lives until the pressure (psychological via economic) becomes too great and they crack up.”–Operations Research Technical Manual TM-SW7905.1, May 1979
