This paper addresses the challenge of analyzing future trajectories, crucial for goal attainment. While some models like the State of the Future Index (SOFI) provide insights into potential trends, they necessitate complementarity with qualitative methods for comprehensive understanding. Despite its efficacy, SOFI’s condensation of diverse variables into a single index may obscure nuances and regional disparities, potentially oversimplifying systemic dynamics. Critique has been leveled against its construction, particularly regarding its weighting system. This study aims to mitigate these concerns by comparing synthesis methods and proposing a statistically rigorous framework for measuring SOFI at the European Union level. By employing those techniques, this paper endeavors to enhance the precision and reliability of SOFI as a tool for identifying future dynamics and evaluating present policies.
