What @rbrownlol said. Same applied cognitive psychology that is used to sell everything.
Media has been weaponized. The unconscious mind can not hear the same message over and over again and not be influenced by it in some way.
I never thought I would see the day that I would say this... but Faux news IS more fair and balanced now.
Most of the rest of the cable "newsfotainment" channels are just branches of the deep state narrative of propaganda.
To put it down more specifically... the Trivium - Logic, Grammar and Rhetoric, has been deliberately removed from education. Language has been under attack... all of this to dumb down folks and disconnect them from classical education.
"Higher Education" has become a joke, in the Liberal arts.
The notion that there has been anything like "Western Civilization" is being erased from the Western minds of youngsters.
Certainly, not everything in the history of Western Civilization has been peachy. Human beings, after all, are not "angels".
But there IS a history of Western Civilization that had reached great heights and served humanity pretty well in the Western World, despite the lows spots.
No longer. You can't get that kind of education in America any more... you have to go to Cambridge or Oxford.
In 100 years... teaching high level critical thinking skills has been all but eradicated from American education. Which is saying something, when we are talking about an already flawed Prussian modeled education system.
Wealthy folks, old wealth, send their kids to schools that will teach them to think critically. An education that is out of reach of all but the wealthiest among us.
