Two thoughts for you.

(1) In the 60s, the KGB did some psychological experiments. They learned that if you bombard human subjects with fear messages non-stop, in two months or less, most of the subjects were completely brainwashed to believe the false message. To the point that no amount of clear information they are shown, to the contrary, can change their mind.

(2) ... My current work area... To make it short, After WWI demonstrated the power and wealth of science, after the 1925 Scopes trial, science decisively won the ancient war between science and religion. A casualty was philosophy. Science claimed all dominion over knowledge. Now STEM has crowded out PE, home economics, manual arts, civics... just about everything. We don't even teach critical thinking which we desperately need in this time of disinformation. It turns out that for much sanity, you need basic philosophy. It is the natural OS of the human brain. Teach it again and many many of the world's problems will go away. ... I'm writing a book that that is part of.
