That is a pretty good rule of thumb. Propaganda appeals to emotion and not reason. My own father called me up and was all hyped up about the current situation in Ukraine. I was surprised by the nonsense that he was repeating. But even the majority here seem to be going along with this lemming like march to the sea. Of course, even the lemmings don’t actually do this... this is basically myth started by a Disney film, White Widerness, from 1958.
It’s human nature.
There will always be a significant portion of the people who will be manipulated by biased information. It’s not always the same people who are succeptible to manipulation either.
It’s the responsibilty of the less emotional people to calm those who fell into the propaganda trap to remain calm and present the other side of the story; to get people to slow down and think.
