Did the Pope Use AI to Write About the Dangers of AI?

Original: Did the Pope use AI to write about the dangers of AI?

A Pangram analysis claims parts of Pope Leo XIV’s AI encyclical may have been AI-written.

The Verge reports that Pope Leo XIV’s latest encyclical, Magnifica Humanitas, may contain passages written with AI assistance. Linch Zhang posted an analysis on LessWrong using the AI detector Pangram, which rated some paragraphs as 40 to 100 percent AI-written. The report frames this as a possibility based on detector output, not confirmed proof of AI use.

This report from The Verge focuses on a controversy with an ironic twist: whether some of the text in Pope Leo XIV's latest encyclical Magnifica Humanitas, which discusses AI's impact on humanity, might itself have been written with AI assistance. According to the report, Linch Zhang published an analysis on the LessWrong forum, using an AI detection tool called Pangram to examine the text, and the results indicated that certain passages were judged to have a 40% to 100% likelihood of being AI-generated. The reason this finding has drawn attention is that the encyclical's very theme is the impact of AI on humanity, society, and ethics; if the document was indeed written with AI assistance, it would prompt the public to reconsider the boundaries between religion, public discourse, and AI tools. However, based on the source information currently provided, this can still only be regarded as the result of an external analysis and a tool's interpretation, not a fact confirmed by the Vatican or the author's team. AI detection tools themselves often carry the risk of misjudgment, so Pangram's percentages should be understood as a model's assessment rather than direct evidence. For Taiwanese readers, the key point of this news is not merely "whether the Pope used AI," but rather how society will verify authorship, transparency, and accountability when AI enters high-trust texts, ethical declarations, and public communication.
