Both genes and culture are subject to evolutionary pressures, and they're often tightly coupled, reinforcing or inhibiting each other via feedback loops. It's rarely accurate to say of a high-level human trait "it is purely innate" or "it is purely acquired".

so each individual is a perceptron and the culture is the network around em?

all these things are true, but how different is it to acquire something via instinct vs acquiring it through culture, where the variable is universal? most people would think if something is not purely acquired it is a product of something that could be different somewhere else

eg, boys are more violent than girls everywhere. part of that delta is instinct, part of it is because culture everywhere expects boys to be more violent, but i would say all of it is innate

I think people underestimate how much cultural evolution drives natural evolution, now that we're no longer struggling for survival. We are surprisingly social and idiosyncratic creatures, compared to what you'd expect from "survival of the fittest"

Another way of saying that is that much, if not most of our natural environment is interaction with other humans
