Reminds me of this quote:
"Exposure to true information does not matter any more. A person who is demoralized is unable to assess true information. The facts tell nothing to him. Even if I shower him with information with authentic proof, with documents, with pictures. Even if I take him by force to the Soviet Union and show him concentration camps, he will refuse to believe it until he is going to receive a kick in his fat bottom."--Yuri Bezmenov 1984, regarding communist propaganda in the United States and how to brainwash a nation
The quote you posted reminded me of another quote.
"If a man is offered a fact which goes against his instincts, he will scrutinize it closely, and unless the evidence is overwhelming, he will refuse to believe it. If, on the other hand, he is offered something which affords a reason for acting in accordance to his instincts, he will accept it even on the slightest evidence." -- Bertrand Russell, in "Roads to Freedom"
