It's not entirely random though. A lot of your actions (like closing cabinets after you're done or looking at specific things for longer periods of time) are generally small reflections of the type of person you are. IF you try to game the system by altering your normal behavior, it's pointless. But if you were to play the game as you would do if YOU were doing it, and don't intentionally change your behaviors, it is somewhat accurate, even if it takes the horoscope/fortune cookie route.
Well, like I said it may not be technically random, but in a real sense it is. Minor actions like closing cabinets and staring at certain things hardly reflect the type of person you are. People are too complicated to be easily categorized like that. For example... if you stare at a picture of a naked woman, is it for scatalogical reasons, or because something about the artwork catches your eye, or because you are offended, or because you dropped the controller? Could be any of those reasons. Thus, to draw any "accurate" conclusions from it is meaningless.
And remember that the horoscope/fortune cookie route works in spite of those predictions being meaningless. The point is that it works because it is vague but specific sounding. It could very well be random, and it would still work.
I'm not necessarily criticizing it, I think it's a cool gimmick. But it is just a gimmick. A game can't actually psychologically profile you, that's just silly. It's not even easy for psychologists to do that.
I don't think anyone was arguing that the game gives you a genuine psychiatric evaluation; that would be completely ridiculous. Of /course/ it's limited. They assign different actions different characteristics, just as psychology does; I would assume that the game is programmed to think that if you close all the cabinets after you've looked in them, you're more neat and tidy than someone who leaves everything open. It makes sense and isn't random. The thread title likely means "was your ending evaluation similar to your personality?".
