G'day white knight, thx for ur reply.
I am aware of the story, it is an old tale, and I first became aware of it in Star Trek Voyager, episode Scorpion parts 1 and 2. It's a cool story which I like, but it is actually one of those stories that can be useful or might not be.
The story as you say is about not trusting an entity that says "trust me".
The interesting analysis for me is that a scorpion truly never lies! So using a entity that never lies, as a means of talking about humans who do lie, creates an incongruence for me. That does not exclude others benefits from the story, nor even my own benefit for I like the story!
Fundamentally animals, insects, tree, birds, none of them lie at all, and thus using a "beast" to tell that story is itself hindering the acceptance that the real issue is that humans do lie and often they won't even admit they lie at all, neither to others, nor even themselves.
I just think the stories point is better said thusly.
"Humans may lie about their own trustworthiness."
No need to bring in fallacious positions about scorpions to express the actual concept about humans in just 7 words.
So, I'm not having a go at anyone, neither yourself, nor the story, nor the author, because such considerations are indeed fun! And revealing under analysis hey mate!
