Abstract:
The evolutionary processes that generate cultural group norms and individual behavior may differ. We found that stated gender preference is based on the social norm of son preference, whilst real-life biases in parental investment were in favor of daughters. The recent history of the region includes dramatic government policy changes that influenced the behavioral ecology of the system by changing access to resources and inheritance rules. We discuss how male preferences may differ from female preferences; and we discuss how social norms and maternal behavior may be generated by different evolutionary processes.
