> GDP per capita, scientific research output, social mobility, and life expectancy These are already incorporated as a part of multiple studies like Good Country index, or Human Freedom index. Having them again would increase their weight. I had many more studies/factors but then narrowed them down to those that have Pearson correlation less than 0.8. > I am kinda of skeptical about the value of Olympic medals per GDP. My goal was to have as many uncorrelated factors as possible, that make sense. Medals per GDP, means a country investing in sports or generally in good health.
