In this case I don't quite understand what are you asking.
LW is unlikely to know whether your adviser / committee will consider the absence of a control group acceptable enough for this project.
You're right, I wasn't very clear on my objectives. Also, my previous comment was needlessly snarky, for which I apologize.
To be honest, I'm not very sure of what I want, myself. I have reason to believe that they'll consider it acceptable regardless of whether there's a control group or not (this being the CS department and not the psych one), so that's not actually an issue. And I've got some desire to do things "properly", for its own sake, and also because it might be fun to do this well enough to turn it into a real publication. But I'm also swamped with a bunch of other stuff and don't have a chance to spend too much effort on this.
So, I guess I dunno what I'm asking, myself.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
