Look at memories.
They spring up on triggers.
Either intentional (trying to remember an event) or unintentional
(a familiar smell)

Retreiving long term memory is not a conscious action. But
asking your memory to "look for it" is a conscious action.

You give the memory system a trigger (like a face or name or situation), and await a response.
If it does not fit, you alter the trigger and await for a different response.

At least this is how I see how the memory works.

Not the memory can be a "decision", But the decision to use this decision can
be evaluated, and changed.
Or split up into smaller decisions which are evaluated in more detail.
Or in the long run retrained / intentionally learned.

I dont see this as unconcious decision making.
More of a decision how much effort one wants to spend on doing so.
How much you want to reflect on your "reflexive" thoughts.
