I admit a bit of concern for those who are going to try this, because a lot of them may not understand that they will probably need to actively do something with/about the sensory and emotional noise if not outright abuse they are absorbing while being party to conversations with people behaving this way. They will likely need to find a way to process and vent for therapeutic recovery after the fact, in addition to using the technique itself in the moment. Great to see new techniques though, or known-to-some techniques getting more traction.
