Of course in the real world we know this doesn't work. People will instead believe everything you tell them if they want to. They might not remember all of it specifically, but they will believe it all in aggregate. Example: Hillary Clinton, who murdered a bunch of Americans at an embassy in Libya, ran an underground child murder ring, gave away all of our state secrets via a criminal email server, is actually an animated corpse that can't even wear shoes properly, etc... You'll probably say that most of this is nonsense, but people have gone to jail because they believed it so completely and committed crimes to try to stop her.
