To take power and keep it, our new Big Brother applies the method of social engineering. Everyone can see the different ways in which this is done every day in the media, where the same stories and the same elements of language are repeated endlessly in a monotonous way, like mantras, with tiny variations on the same theme, and all to try to condition Pavlovian mental reflexes in the population, trained to choose a victim, an executioner, a savior. An impression of general robotization emanates from all of this, which is only contradictory in appearance, with the production of chaos. Indeed, to better automate human behavior, to better program it, plan it, control it, pilot it, mechanize it, there is nothing like plunging it into chaos, that is to say panic. The branch of behaviorism that studies the effects of extreme stress has shown that in situations of great anxiety, of vital urgency, of panic, the reptilian brain and its primary functions prevail over the dialectical neocortex. This sidelining of the complex functions of the brain allows the number of possible behaviors to be reduced to those of survival: instinctive, stereotyped, rigid behaviors, easy to model and predict, and above all short-term, short-sighted and unplanned, of the "reflex" type, therefore sometimes counter-productive and self-destructive, because they are thoughtless. The reduction of behavioral diversity and complexity is accompanied by a reduction in behavioral uncertainty, and therefore by a better predictability of behavior. To effectively take control of a group, it must never have time to think. The new Big Brother seeks, like the old one, to homogenize our behaviors and to bring their diversity back to unity. But the new Big Brother understands that to achieve this, it is more efficient to rely on disorder and anarchy than on a lucid social order whose stability can turn against Power itself. This book invites you to discover the principles of social engineering and governance by chaos.
