So you attribute anything you can't explain with the mind to the unconscious? It isn't me that doesn't like horseradish, it's my unconscious? I bet if you think about it you can figure out why you don't like them, and even if you can't, that doesn't mean it is the unconscious.
That is unless you were using that example as a way to define the unconscious. In which case, I'm an idiot.
I was using food preference as one example of the vast amount of personal characteristics that make up a person, that we have no control over.
Here is another example:
Suppose you are hungry. You are conscious of your hunger, but you are not conscious of the decision to become hungry. The conscious mind can theorize about why you are hungry - maybe you have not eaten in awhile, maybe you just smelled something cooking, or maybe it is 7 a.m. and you always eat at 7 a.m., but those are just guesses. The part of the mind that decided to send you looking for food has it's own reasons, and it does not bother to clue you in to them most of the time. Now, it is possible that hunger is a mechanical reaction to certain stimuli, no thought required, but evidence suggests otherwise. As anyone who has ever ordered their favorite pizza would agree, you can be hungry even while completely stuffed.
The classical analogy used is that of the 'tip of the iceberg'. A mind is composed of three elements, the id, ego, and superego. Only a small fraction of the ego is conscious. The conscious mind is the part that decides how to act. It rounds up the desires supplied by the id, the rules supplied by the superego, and whatever memories or hopes the rest of the ego contains and makes a decision on how to behave.
An example:
Id "I am hungry, and sleepy, and thirsty"
Superego: "If you eat in bed you will get crumbs, that is bad. If you eat before you go to sleep you will get fat, that is bad." (not first person because superego is supposedly an internalized parent)
Ego (unconscious): "I remember drinking while lying down and it did not work very well, I choked."
Ego (you): "Okay, I will eat and drink first, then I will go to bed. I don't care about getting fat because I am really hungry. Okay, I do care about getting fat, I will remember to eat earlier next time.".
My dog, on the other hand, does not seem to have much of a conscious. She will regularly go lie down, jump up to drink, go lie down again, lick her butt, jump up to get one piece of food, bring it into bed, forget about it and go back to sleep, etc.
