Outcomes Override Identity: How Forward-Looking Responsibility and Outcome Valence Shape Legitimacy and Support in AI Welfare Systems
摘要
As artificial intelligence (AI) is increasingly integrated into welfare governance, concerns about its legitimacy and public support are emerging. Across four studies with Chinese participants (N = 1336), this research examines how decision-maker identity (AI vs. human) influences public evaluations of legitimacy and program support, and explores the mechanisms underlying these effects. Studies 1 and 2 indicated that when outcome information was absent, legitimacy judgments of AI and humans were similar, although support slightly favored human-administered programs. These differences were associated with perceptions of the decision-maker’s capacity to bear forward-looking moral and social responsibilities, rather than with perceived fairness or experience. However, these identity-based differences were not robust. They did not remain significant under conservative Holm–Bonferroni corrections and were attenuated when direct outcome (Study 3) or side-effect information (Study 4) was provided. Individual beliefs in machine heuristics and justice also moderated responses to AI and human decision-makers. These findings suggest that public responses to AI in welfare governance are conditional, rather than reflecting stable preferences or generalized resistance. They further highlight the role of perceived responsibility-bearing capacity in shaping acceptance and support in decision-making scenarios.
