Query: A renormalization group theory of cultural evolution   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 among agents is defined as the overlap of mental representations and
is characterized using an adequate order parameter. As the importance of social
interactions increases or agents become more intelligent, we observe and
quantify a series of dynamic phase transitions by which cultural coherence
advances in the society. A similar phase transition may explain the so-called
"cultural explosion" in human evolution some 50,000 years ago.
