【题目】 Rice, Risk, Cooperation, and Gene x Culture Coevolution: A Gene for Social Efficiency

 

【摘要】

 

To investigate how culture induced by the irrigation-intensive rice cultivation influences people's risk

 

taking and cooperative behavior, we make use of several individual choice tasks and behavioral games together

 

with 1,104 university students recruited in Beijing. We find that cooperativeness proxied by the level of

 

contribution in the public goods game varies positively with the proportion of rice cultivation in

 

subjects' birth province. This finding is mutually replicated in an independent study by Zhou (2017).

 

It is further corroborated by examining survey data relating to cooperativeness from the 26,000 strong

 

China Family Panel Studies. At the same time, we find a positive relation between the proportion of rice

 

cultivation and risk taking. This latter finding renders a novel perspective to the reported East-West

 

differentiation in risk attitude and together with the link to cooperativenesspoints to an underlying

 

social efficiency orientation. We further identify a genetic basis for both cooperativeness and risk

 

taking. The dopamine receptor D4 (DRD4) exon III coding region polymorphisms 2R genotypes are associated

 

with increased cooperativeness as well as risk taking. Finally, we find evidence of a gene-culture

 

coevolution across 12,000 years in favor of the 2R genotypes of DRD4 using province-level history on the

 

introduction of rice farming.
