Results of causal mediation analyses showing the influence of whether an official is corrupt on corruptibility-related trait inferences, as mediated by facial structures (Study 4a). A mediation model was constructed for each of the eight facial metrics separately and was tested with data from Study 1 and Study 2. Two of the eight facial metrics, (a) face width-to-height ratio and (b) face width/lower-face height, showed significant indirect effects. Unstandardized coefficients are shown, and standard errors are given in parentheses. Coefficients for path a were estimated in linear regression models. Coefficients for path b and path c′ were estimated in linear mixed models. The indirect effects of path ab were estimated with RMediation in R. Photo characteristics were included as covariates in all models; for simplicity, these variables and the corresponding paths are not depicted in the figure. No indirect effect was found for the other six facial metrics. Asterisks indicate significant paths (*p < .05, **p < .005, ***p < .0005). CI = confidence interval.
