Public Perceptions of Judges' Use of AI Tools in Courtroom Decision-Making: An Examination of Legitimacy, Fairness, Trust, and Procedural Justice.

This study examines the role of artificial intelligence (AI) in judicial decision-making, focusing on bail and sentencing contexts. We examined public perceptions of judges who use AI tools compared to those who rely solely on expertise. Using an experimental design, participants (N = 1800; stratified by race/ethnicity and gender) were presented with vignettes depicting judges using varying levels of AI assistance. Key outcomes included perceptions of judicial legitimacy, procedural justice, and trust in AI, with analyses stratified by racial groups (Black, Hispanic, White). The results revealed that judges relying on expertise were generally rated higher in legitimacy than those using AI; however, significant racial differences emerged. Black participants showed greater trust and perceived fairness in AI-augmented decisions compared to White and Hispanic participants. Open-ended responses further highlighted social psychological themes regarding the symbolic meaning of AI in judicial processes. These findings underscore the complexity of integrating AI in the judiciary, emphasizing the need for transparent and equitable implementation strategies to maintain public trust and fairness. Future research should explore underlying factors influencing these perceptions to inform policies that address racial disparities and enhance trust in AI-assisted legal decision-making.
