In earlier societies, community kept people sane.  I mean this in a real sense. Interaction with others is how we stay sane.  Fidelity to reality means more than recognising and responding appropriately to inanimate matter.  Interaction in the experiential realm gives us constant dynamic feedback to our words and actions, our behaviour; helping us to be rational.

That stabilising factor is, for many, now absent.

In the digital realm, it’s too easy to interact almost exclusively with like-minded people who reflect back at you not correction, but amplification, of your psychosis.
