Analysis suggests Pope Leo XIV may have used AI to write portions of his encyclical on AI's dangers, with detection tools indicating 40-100% of certain paragraphs were AI-generated. The finding raises questions about authenticity and irony, as the document warns against AI's impact while potentially being partially authored by AI systems.
The irony is striking: a papal encyclical warning about artificial intelligence's risks may itself be partially written by AI. Researchers analyzing Pope Leo XIV's recent encyclical *Magnifica Humanitas* found linguistic signatures consistent with AI-generated text, particularly the overuse of words like 'genuinely' that appear frequently in outputs from Anthropic's Claude model. Detection software Pangram flagged between 40-100% of specific passages as potentially AI-written, with some sections scoring as high as 62% AI-generated content. This development highlights a growing credibility challenge in the AI era: as AI writing tools become more sophisticated and accessible, distinguishing authentic human authorship from machine-assisted or machine-generated content becomes increasingly difficult, even for high-profile institutional documents. The Vatican has not commented on the analysis, leaving questions about whether AI was deliberately used as a drafting tool or if the analysis represents false positives from imperfect detection methods. The broader context involves ongoing institutional grappling with AI integration—many organizations now use AI for research, drafting, and analysis while maintaining official human authorship. For stakeholders in AI development and deployment, this incident demonstrates both the practical utility of large language models and the emerging authenticity concerns they create. The situation may accelerate discussions around transparency requirements for AI-assisted content, particularly for authoritative institutional voices. Moving forward, organizations may need to establish clear policies on AI tool usage and disclosure, as audiences increasingly scrutinize source material authenticity.
