Ok, this in me + Alcohol...
But I'll stand by what I put up there... There are probably more than one or two folks who've studied linguistics here.
Pragmatics is the study of language and context (including subjectivity and intra-subjectivity). The psychology of a producer or receiver of any given message is, by definition, part of the context of that message. Any message's meaning is heavily dependant upon that context.
What you're talking about is an ENORMOUS field of research and knowledge. I think people who know about this will be put off of replying by the amount of avenues that it's possible to go down from your speculations above and people who don't know anything about it will be put off because it seems wild.
I know you may think you've been specific, but I really think you might have hit a completely unsweet spot between two groups.
I could, of course, just be drunk.

There's an issue of reflexivity that you raise as well, which is CONTROVERSIALLY covered by ethnolinguistics and linguististi relativity.
