I’ve been working inpatient psychiatry for almost a decade now and here’s how we talk people out of delusions…

…you don’t. Confronting the delusion directly helps their brain practice protecting the false belief system and strengthens the neural links / pathways. It’s like the ruts made by a wagon wheel, the more the wagon travels the path the deeper they get. All you can do is send the wagon somewhere else and wait for the ruts to erode on their own.

So if you really do love this person and want to bring them out of it, do your best to send the wagon somewhere else. Just glaze over for a second while they rant, then change the subject. Try to connect over knitting or gardening or woodworking or music or old movies or sports or whatever other hobby or social activity / discussion you can use to connect with them over that’s reality based.

That’s how COVID sucked them into all this. It broke up the knitting groups and gardening clubs and cooking classes and all anybody had left to socialize with was Facebook conspiracies. If we want out, we need to focus on rebuilding those communities.
