Abstract:
Peer cultures can contribute adaptive innovations, but their capacity for contribution depends on the environmental risk landscape. High-risk environments promote conservative cultural transmission, suppressing contributions from peer-driven exploration, while low-risk conditions allow peer cultures to thrive, generating, and spreading novel solutions. Socioeconomic stratification also influences these dynamics, creating cultural divides in how peer cultures operate.
