Data from: Sex differences in costly signalling in rural Western China

Numerous empirical studies suggest that individuals convey their
commitment to communities and impart the qualities of being a reliable
partner through costly behaviours. We collected religious practices data
ranging from daily trivial practices to infrequent grand distant
pilgrimages in an agricultural Tibetan village. We predict that
1) villagers who invest more in religious practices are more
likely to be nominated as having various prosocial qualities.
2) Investment in grand distant pilgrimages has more efficacy than
daily trivial religious acts on recognition of prosocial qualities.
3) The males are more likely to receive nominations than females
across all prosocial traits. Using Hurdle Models and Exponential Random
Graph Models, we found that religious practice is mediated by demographic
factors like wealth rank, age, and the gender. Daily religious investment
positively associates with nominations of devoutness, but not with other
prosocial traits. Distant pilgrimage positively associates with
nominations of devoutness, as well as other prosocial traits. Females are
inclined to prefer investing in daily religious acts, but males are
inclined to invest in distant pilgrimages. Generally, females receive
fewer nominations than males across all prosocial traits.
