There are a few types of brain washing. One of them is isolation. Where someone is locked in a room with pictures of the beleif they want to get to them are hung on walls. However, that takes time, and the law would notice. As for another kind, it's immediate hypnosis, but that only works if they WANT to be hypnotyzed. in other words, you could try to hypnotyse me to play fortnite, but that would not work cuz i hate it. Then they have pursuasive. That is bribary. That is the only one that is logical. HOWEVER, Some people would not change their beleifs in public while others would. And also, Why would NASA want people to beleive there is a round earth?
Is this enough?
