In both cases, the conscious mind determines the signal and the unconscious mind determines the action.

Look more closely. All preferences are equal, in the sense of being within the same system -- and this includes signaling preferences. The drunk prefers to drink and prefers to not be thought of as preferring that. But these are not concepts of a different nature; they can both be expressed within the same behavioral preference system.

IOW, both the Cynical and Naive theories are wrong; we only have one set of preferences, it just sometimes works out that the "best" compromise (in the sense of being an approach that your brain can discover through trial and error) is to say one thing and do another. But both the saying and doing are behaviors of the same type; "conscious" vs. "unconscious" is a red herring here.

Now, if you want to say that you don't consciously identify with some subset of your choices or preferences, that's fine, but it's not useful to claim that this is the result of some schism in your being. It's all you, you just aren't being conscious of that part of "you" at the moment.

The "unconscious mind" isn't a real entity; it's not a "mind", in the anthropomorphic sense. It's just whatever you're not paying attention to right now, that keeps on going. If you pay attention to your breathing or your heart rate you can learn to control them. If you pay attention to your feet you'll know where they are right now. And if you pay attention to what you actually get from your "akrasic" behavior, you'll realize it's something you genuinely want.

What you haven't been doing, is negotiating fairly among all your "interests" (to use Ainslie's jargon), or cleanly prioritizing your "controlled variables" (to use Powers's).
