Estimated gender differences in the five outcome variables for each country. Plotted are the point estimates and the 95% CIs of the gender difference (0 “male”, 1 “female”) in (a) left-right political preferences, (b) trusting behavior, (c) life satisfaction, (d) happiness, and (e) health status for each of the 39 countries surveyed in the ESS. All point estimates and confidence intervals are standardized based on the pooled standard deviations in the outcome variables and can be interpreted in terms of Cohen’s d units (see Methods for details). Comprehensive meta-analytic forest plots for each of the five outcome variables are presented in Supplementary Figs. 1–5.
