The MacArthur Ladder and the social comparison questions presented to participants.
Fig 2.
The relationship between Social Comparison Index score and responses to the MacArthur ladder across populations.
Lines are linear regression lines. Shaded regions represent 95% confidence intervals.
Fig 3.
Violin plots demonstrating the distributions of Social Comparison Index scores across regions.
The outlines illustrate kernel probability densities at each given score. The black diamonds indicate mean scores.

Effects and standard errors from linear models predicting ladder placement in the full sample (Model 1), the full sample with interactions (Model 2).
The baseline for region is the United States. Table also shows goodness of fit.
