Analysis using seemingly unrelated regressions yields similar results.
The total positive impact of rationality on happiness is generally greater among rich nations.
The direct positive impact of rationality on happiness is generally greater among rich nations.
The indirect positive impact (via income) of rationality on happiness is generally greater among rich nations.
The y-axis shows the relationship between rationality and happiness for each country, based on the regression coefficients.
The x-axis shows national income (GNP per capita).
