A book by Professor Jun Shimabukuro was recalled by publisher Kobunken in Japan after it was found to contain fabricated legal cases generated by AI. The author used AI to search for legal precedents, but included non-existent cases without verification, leading to misinformation and reputational harm.[AI generated]
Why's our monitor labelling this an incident or hazard?
An AI system was explicitly used to generate search results for legal precedents, which were then incorporated into a book without proper verification. The AI's involvement directly led to the dissemination of false information, which constitutes harm to the integrity of information and potentially to the academic community and public trust. This fits the definition of an AI Incident because the AI system's use directly led to a violation of intellectual property and academic standards, and harm to the community through misinformation. The publisher's recall and the university's response are reactions to this harm, but the core event is the AI-driven misinformation causing harm.[AI generated]
