I think “retreat” is used pretty colloquially and doesn’t imply pseudo-therapy.

I was referring specifically to these sorts of things. Retreat doesn't always include this, but sometimes it does, and when it does it's a stupid idea.
Unless maybe done by professionals?
I never have been to one such retreat, but I know human conflicts and I know what difference it can make, if skilled people can mediate.
