Maybe there is a way to use this concept of reducing stress with a gesture without invoking supernatural gibberish. I mean to me it seems totally plausible that having a person there that is trying to help you in and of itself can reduce stress. Also if they touch you, that seems like it could definitely reduce stress also. Or just the psychological effect of knowing that there are people who care, that seems like it…
I used to think like that too, but I'm more open that sometimes a story, any story, allegory can be helpful in many contexts, by creating an identity, an aesthetic quality of the thing; help us conceptualize it. Since this in particular is about psychological phenomenon, I think it perhaps shouldn't be discarded. The question would be (if the story is an important part of a working practice) how to keep the story from being confused with fact. I think that's achievable (treat it as a mythology, or something). I don't think anyone would defend the banning of telling stories to children or fiction movies.
