What if the solution to misinformation is _more_ information? If 99 % of all information that you come across is wrong (and you know it), you’re forced to start thinking critically or just believe in random things.
That is, if someone believes that we’ve never been to the Moon, feed them with information of the same logical structure that we’ve never been to the North pole. If someone believe that a politician is guilty of something just because he’s been accused of it, make the same accusations towards one hundered other random politicians. If someone is seeing ghosts, tell them that you’ve been seeing dinosaur ghosts in ballerina costumes.
In order to not die in such an environment because you haphazardly eat led for breakfast, you’re forced to develop critical thinking skills.
