I see what you mean but I am not sure we are exactly on the same page. Let me try to break it down and you can correct me if I misunderstood.
It seems to me that you are thinking of computation as a process for "coming up with an answer" but I am talking about having no answers at all but acting out patterns of actions transmitted culturally. Even before verbal elaboration. This transmission of action patterns was first performed by rituals and rites as can be observed in primitive cultures. They were then elaborated as stories, myths, religion, drama, literature etc. and of course at some point became an element for manipulation by abstract thought.
So the difference with what you are saying is that you are assuming an 'elaboration of information' by the brain when on the level of ideas the elaboration happens culturally through the evolutionary process. The consequence is that the values have to be accepted (believed in) and then can be (maybe) experientially confirmed. This also explains the 'ought from an is' issue.
Maybe it's because I'm coming from a computer science background, but I'm thinking of computation as much more basic than that. Whether you're elaborating myths or reacting to the sight of a snake, your brain is performing calculations.
I think we agree that our values are deeply ingrained, although it's much more difficult to say exactly to what level(s). I do not agree that our values are selected through memetic adaptation, or at least that's only part of the story.
If it's worth saying, but not worth its own post, then it goes here.
