The cultural sub jectivity is a social theory of the reflexive actor that is historically situated in a material and cultural context. It is important for computational social science to begin developing to...

We present a theory of cultural evolution based upon a renormalization group scheme. We consider rational but cognitively limited agents who optimize their decision making process by iteratively updating and refining the mental representation of their natural and social environment. These representations are built around the most important degrees of freedom of their world. Cultural coherence a...
