Cultural Evolutionary Mismatches in Response to Collective Threat

Across the millennia, human groups have evolved specific cultural and psychological adaptations to cope with collective threats, from terrorism to natural disasters to pathogens. In particular, cultural tightness, characterized by strict social norms and punishments, has evolved as one key adaptation that helps groups coordinate to survive collective threats. However, interferences with threat signals that facilitate tightening can lead to cultural mismatches—either too much or not enough tightening. Gelfand will discuss two examples of cultural mismatches: the COVID-19 pandemic (a case in which collective threat is real, but there is a resistance to tightening) and the rise of populist movements (a case in which exaggerated threat leads to unnecessary tightening), and highlight theoretical and policy implications of cultural evolutionary mismatch theory.
