i also haven't heard that name before, but this seems to be along the same lines that we were taught in dialectical behavior therapy within interpersonal relationship skills. one great use for this skill for people with difficulities in emotional self-regulation (usual in trauma-based disorders i believe, i was stamped with bpd myself) is to learn to detach emotions from whatever it is that you need to talk about, as to minimize the possibility of an overwhelming emotional state. i personally used to go completely delusional very easily in enough emotional stress, so much so that reality that everyone else could see didn't really matter to me because i saw a different reality that i knew completely and utterly to be true. this tendency has lead to many moments of distress to myself personally and many more around the world, and this skill is one of the reasons i don't suffer as much anymore.

which is why it's so sad to see such rampant ableism in the comments. people completely misunderstanding the entire concept (because of it's sucky name) and then just completely shitting on apparently everyone, someone there decided to bring up their general bigotry towards sexual minorities there or something.

anyway, nothing to do with the question really, just some personal musings
