  • Regression results are reported in SI Appendix, Table S6. Sample sizes for each of the group are presented in brackets. Mosuo majority (minority) equals one if a student is in the school–grade cohort in which more (less) than 50% of his/her cohort members are Mosuo. A positive coefficient indicates that one becomes less risk averse. In rows 4 and 5, P values from the test for equality are reported.
