@Briancrc,
Yup. Occam's razor is a useful heuristic, and I try to use it when in doubt.
I've been working on the infinite regress aspect of conscious decision-making. I'm still not at a conclusion, but maybe writing it out here will help. Upon introspection, it seems that I don't consciously make a decision to make a decision, then make the decision. My subjective perception is of a thought appearing unbidden in the stream of consciousness, for example, "Out of coffee. Get more."
Then I think about what preceeded that. My glance at my coffee cup wasn't consciously premeditated; it has long ago become a reflex action. The perception of the emptiness of the cup certainly wasn't volitional. Sometimes instead of "Get more," the thought will arise, "Wait a while. You've had too much this morning."
Beneath that, it seems, come various visceral, pre-verbal impulses or feelings, like "want," "strongly want," "weakly want," "don't want," etc. I suspect, but am not sure, that my body has an unconscious awareness of my caffeine level at any given moment, and the conscious thoughts are the product of that momentary dipstick measurement. I can see conditioning and biochemistry covering all of those phenomena and even more complex ones.
I don't see the need, so far, for any sort of disembodied executive decider that works independently of physiology. This explanation would work to get rid of the infinite regress that such a disembodied executive leads to, so at the moment, at least, it seems to be the better explanation.
