They note that cultural evolution is different than genetic evolution. The latter is based more on special purpose “innate human psychological mechanisms” (30). They even equate these mechanisms with the “frame problem” (34). They also said:

“All normal human minds reliably develop a standard collection of reasoning and regulatory circuits that are functionally specialized and, frequently, domain-specific. These circuits organize the way we interpret our experiences, inject certain recurrent concepts and motivations into our mental life, and provide universal frames of meaning that allow us to understand the actions and intentions of others. Beneath the level of surface variability, all humans share certain views and assumptions about the nature of the world and human action by virtue of these human universal reasoning circuits.”
