The dumbing down of society started with the so called enlightenment era, called the age of reason. During the time of the French Revolution. Where anything can be subjectively justified by reason.
Where it ends up into relativism. Claiming there are no absolutes to truth, but relative to everybody subjectively.
Leaving people to make up their own truth. Where information is biasly selected and confirmed by reason of how someone individually thinks to formulate their own views and ideas, which is inconsistent to objective reality.
This has not only given rise to pseudo intellectualism, but pseudo intellectualism and insanity respectively.
Trying to intellectualise idiocy and insanity. To the point where language is inverted to call good evil and evil good.
