On a very basic level, I am an algorithm receiving a stream of sensory data.

So, do you trust that sensory data? You mention reality, presumably you allow that objective reality which generates the stream of your sensory data exists. If you test your models by sensory data, then that sensory data is your "facts" -- something that is your criterion for whether a model is good or not.

I am also not sure how do you deal with surprises. Does sensory data always wins over models? Or sometimes you'd be willing to say that you don't believe your own eyes?

I don't understand what you mean by trust. Trust has very little to do with it. I work within the model that the sensory data is meaningful, that life as I experience it is meaningful. It isn't obvious to me that either of those things are true any more than the parallel postulate is obvious to me. They are axioms.

If my eyes right now are saying something different than my eyes normally tell me, then I will tend to distrust my eyes right now in favor of believing what I remember my eyes telling me. I don't think that's the same as saying I don't believe my eyes.

group selection

When you said "more closely linked to genetic self-interest than to personal self-interest" did you mean the genetic self-interest of the entire species or did you mean something along the lines of Dawkins' Selfish Gene? I read you as arguing for interests of the population gene pool. If you are talking about selfish genes then I don't see any difference between "genetic self-interest" and "personal self-interest".

The idea of the genetic self-interest of an entire species is more or less incoherent. Genetic self-interest involves genes making more copies of themselves. Personal self-interest involves persons making decisions that they think will bring them happiness, utility, what have you. To reiterate my earlier statement "the ability of individual members of that species to plan in such a way as to maximize their own well-being."

is a series of appeals of to authority

Kinda, but the important thing is that you can go and check. In your worldview, how do you go and check yourself? Or are "streams of sensory data" sufficiently syncronised between everyone?

And I go look for review articles that support the quote that people care about social status. But if you don't consider expert opinion to be evidence, then you have to go back and reinvent human knowledge from the ground up every time you try and learn anything.

I can always go look for more related data if I have questions about a model. I can read more literature. I can make observations.
