I get it in this context. But again, it is misleading. There is no subconscious part of the brain that makes conscious decisions - and that's what it sounds like when you say, "Phobias and irational fears are a good example of the subconscious making decisions for a person."
I wouldn't say that its misleading, I was just using it as an example of something that is not controlled by the "conscious mind". You can know that whatever you fear (a spider for example) can in no way hurt you but you will still go out of your way to avoid it.
Do you have any irrational fears (spiders, planes, snakes, heights)? I'm sure you do, we all do, and if you do how do you explain what causes them?
A more accurate way IMO to say it would be that phobia's and irrational fears are chemical reactions due to stimuli, that act in a specific way because of the way the person's brain developed.
Any action taken is a chemical reaction due to stimuli, that act in a specific way because of the way a person's brain developed. That doesn't mean you are consciously aware that you are doing it, my younger brother used to pick his nose all of the time and didn't even realize he was doing it.
