Abstract: Evaluating country performance using a single index is often insufficient because these indices typically specialize in specific areas. This study aims to provide a more comprehensive assessment of country performances by using various indices together, including the Human Development Index (HDI), Environmental Performance Index (EPI), Global Innovation Index (GII), World Happiness Report (WHR), and World Justice Project Rule of Law Index (WJP RLI). Additionally, the results of these indices are aggregated using the Borda, Copeland, Dodgson, and RAT techniques, and the outcomes are compared. The study shows that the RAT technique provides more precise and consistent results compared to the other techniques. The RAT technique was able to rank all countries fully without assigning the same rank to multiple alternatives. In contrast, the Borda, Copeland, and Dodgson techniques faced difficulties in fully ranking the countries, often assigning the same rank to multiple countries. Nevertheless, a high degree of consistency was found among the rankings obtained with the used techniques. Considering country performances, Denmark, Finland, and Sweden demonstrate high performance, while Romania, Hungary, Bulgaria, and Montenegro show lower performance. Turkey generally ranks lower and needs improvements in various areas. The study emphasizes the importance of policy reforms, investments in education and health, environmental sustainability, and innovation.
