Why Social Science Needs Evolutionary Theory

Here is an excerpt:
Human cognition and behavior is the product of the interaction of genetic and cultural evolution. Gene-culture co-evolution has allowed us to adapt to highly diverse ecologies and to produce cultural adaptations and innovations. It has also produced extraordinary cultural diversity. In fact, cultural variability is one of our species’ most distinctive features. Humans display a wider repertoire of behaviors that vary more within and across groups than any other animal. Social learning enables cultural transmission, so the psychological mechanisms supporting it should be universal. These psychological mechanisms must also be highly responsive to diverse developmental contexts and cultural ecologies.
Take the conformity bias. It is a universal proclivity of all human psychology—even very young children imitate the behavior of others and conform to group norms. Yet beliefs about conformity vary substantially between populations. Adults in some populations are more likely to associate conformity with children’s intelligence, whereas others view creative non-conformity as linked with intelligence. Psychological adaptations for social learning, such as conformity bias, develop in complex and diverse cultural ecologies that work in tandem to shape the human mind and generate cultural variation.
