Are rhetorical devices, like metaphors, part of the encoding of a message?
I am 100% in favor of reopening this.
I understand in its original form it was perhaps "Unclear" what was being asked, but to close it as outside the realm of graphic design is really bad in my opinion.
Whether psychologists would or would not also have an opinion a graphic designer should have purpose behind their design decisions which is precisely what this question is about.
Now that its been edited to be a bit clearer I'd like to nominate it for reopening without using mod powers to just override everyone else.
