Isn't that the point of the story though? To say "we need to have a conversation about facts, rather than something like always saying "we need to be more careful next time" when there's a problem? As far as I can tell, the author doesn't really give any generalized advice on how careful you should be, he's just pointing at the "carefulness dial" and telling people to make an informed decision.
