And I feel you are unaware of the division of labor between the subcortical structures and the cortex.
The thalamic nuclei and amygdala (subcortical structures that are the bulk of the subconscious) have no idea what a piece of cake or cheese looks like. They have no idea what your mother-in-law looks like; they have no idea what your social obligations are. They have no idea what is work or play to you. Mental projections, social interactions, mental experience - all are perceived and digested and spoon fed to the subcortical structures by the cortex.
What the cortex does learn is how to break these things down to the point where they can be matched up with an ignorant tyrant that can only make the most simple of decisions. These primitive decisions are elaborated into the complex actions that we learn as we transition from a helpless baby to the wonderfully nuanced humans that we are.
To get some idea what the subconscious really is all about - look at any newborn baby. At this point the primitive brain is in the drivers seat.
These old subcortical structures know hunger and thirst and cold and hot and salty and sweet and bitter and pain. They have very simple visual primitives like general faces and expressions. They know happy and sad and anger and curiosity. A few built in instincts and reflexes. Stuff what babies know. And not much else.
The cortex learns to layer behaviors on top of these primitive actions but never forget that the old part of the brain is firmly in the loop - all perceptions are simplified and presented to this old part of the brain and it makes it’s animal decisions. No action ever originates in the cortex - it is a strictly a passive processor. We take these orders from the thalamic nuclei and and make it happen.
This is you - with a fancy veneer of leaned human perceptions and behaviors on top. This partnership is the you that you are asking about. A dumb boss with a really smart advisor. It is a wonderfully close and finely tuned relationship. It took your whole life to learn it. From both the inside and outside the division of labor is hard to discern. Researcher have teased apart some of the dividing line and it is clearly there if you know how to look.
