Human Development in the Algorithmic Era: A Quantitative Analysis of the Impact of Adult Education and Training on Soft Skills

The accelerating diffusion of Artificial Intelligence (AI) and automation critically highlights the strategic importance of soft skills, interpersonal, cognitive, and self-management capacities that distinguish human agency and foster holistic individual development in digitalized workplaces. This paper examines whether adult education and training (AET) stimulates soft skill development in Italy, a context where policy and employer-driven programs have historically prioritized technical competences (hard skills). Using nationally representative data from the INDACO-Adults 2022 survey (N = 40,477), we construct a soft skills index via a Graded Response Model (GRM) and estimate OLS regressions to assess the association between AET participation and self-perceived skills. Results indicate a positive and significant relationship, robust to multiple controls. Heterogeneous effects emerge: surprisingly, retired adults and individuals unable to work show particularly strong associations, suggesting a profound impact on personal well-being and re-engagement, while employed and unemployed adults display more modest gains. Importantly, individuals who already value training report substantially higher soft skill levels, underscoring the relevant role of intrinsic motivation and a supportive learning culture. By linking pedagogical theory with large-scale quantitative evidence, the study highlights the need for policies that embed transversal skills into AET curricula and promote lifelong learning culture as a human and civic priority, as well as an economic one.
