Orwellian “crimestop”

“Crimestop…includes the power of not grasping analogies; of failing to perceive logical errors, of misunderstanding the simplest arguments if they are inimical to Ingsoc [Socialist Principles of Oceania], and of being bored or rebelled by any train of thought which is capable of leading in a heretical direction. Crimestop in short means protective stupidity… The world view of the Party imposed its self most successfully on people incapable of understanding it. They could be made to accept the most flagrant violations of reality because they never fully grasped the enormity of what was demanded of them, and were not sufficiently interested in public events to notice what was happening. By lack of understanding they remained sane. They simply swallowed everything, and what they swallowed did them no harm because it left no residue behind; just as a grain of corn will pass undigested through the body of a bird… In the long run a hierarchical society was only possible on the basis of poverty and ignorance.” George Orwell — 1984
