Extended Data Fig. 1: Alternative definitions of kinship.
From: Cognitive representations of social networks in isolated villages
In addition to the binary definition of kinship (used in the primary analyses) and genetic relatedness (Fig. 3b), we consider the effects of (a) specific type of kinship tie as a categorical variable and (b) distance in the kinship network. We find that the categorical results are consistent with the binary definition, and distance in the kinship network broadly corresponds to that of genetic relationship. In both panels, gray bands (LHS) displays 95% confidence ellipses around the mean estimates. Error bars (RHS) display 95% confidence interval around the mean estimates. Results are from n = 9,998 survey respondents in both panels, corresponding to 177,928 individual responses for the TPR estimates, and 477,393 responses for the FPR estimates.
