I want to preregister the following predictions before I dig into the data:
Of democratic (non-subsidiary) nations (as judged by having a EIU Democracy Index rating of at least “flawed democracy”; Hong Kong and similar are excluded due to not being sovereign), I expect for both the World Happiness Report and the Index of Economic Freedom, the median among nations that have at least one house of the national legislature elected via a form of proportional representation directly by the people, will be higher than the median for nations that do not, with 85% confidence
I further expect the median among PR democracies will be higher than the 75th percentile best rating for non-PR democracies with 60% confidence.
