A recent study from the University of Chicago Law School highlights significant differences in decision-making between AI judges, specifically OpenAI's GPT-40, and human judges, suggesting potential implications for the future of the legal system.

The study found that GPT-40 adhered to legal precedent over 90% of the time, demonstrating a stark contrast to human judges who were influenced by emotional factors.

In fact, human federal judges were swayed by sympathetic portrayals of defendants 65% of the time, often deviating from established legal precedent.

Interestingly, law students in the study followed legal precedent about 85% of the time, indicating they were less influenced by emotional factors than human judges but still more so than the AI.

Statistical analysis confirmed that the differences in decision-making between AI and human judges were significant, with a p-value of less than 0.01 indicating that these patterns were unlikely due to chance.

Despite efforts to train GPT-40 to consider emotional and social contexts, researchers found it could not incorporate sympathy into its reasoning, underscoring the inherent differences between human and AI judicial approaches.

The study included scenarios where judges were made aware of potential flaws in convictions; however, human judges still allowed sympathy to influence their decisions, while GPT maintained a strict legal approach.

These findings fuel the ongoing debate between legal formalism, which emphasizes strict adherence to legal rules, and legal realism, which recognizes the impact of extralegal factors like emotions and social context.

The implications of this research raise philosophical questions about justice, highlighting a tension between the AI's consistent application of the law and the human judges' capacity for empathy and nuance.

Experts predict that AI will play a significant role in the legal field, with guidance already being released on integrating AI into courtrooms, despite ongoing concerns about AI fabricating case law.

Ultimately, the authors conclude that the debate over the superiority of AI versus human judging may hinge on broader jurisprudential questions rather than merely technological advancements.
