Quarantine Hall Monitors

In a high-information society or a society where the foundational lies are exposed as lies, hall monitors cannot deal and go insane. Whenever someone strays too far from what they know, they feel alienated and disturbed and terrified, and predictably become violent.

They need to be put in a box with other hall monitors which shuts out all the extra information. You can't allow them to run around unsupervised. I expect it's the high agreeableness that does it. Don't think of agreeableness as capacity to conform, but as obligation to conform. If the society lacks conformity, they cannot even.

Either quarantine or you have to kill them all. Let's go with the box option.
