Mass delusion is the result of the effort. Propaganda is one of the techniques. But it mentioned things like you create a consensus of something that's totally absurd. You get people believing something totally absurd, however that's done, and then the people with common sense come along and say, "No, no, no. That's totally wrong," and they end up being the new kooks and weirdos. They are the ones society thinks are cockeyed and weird.
