AI detectors flag Pope Leo XIV's encyclical
ai analysis suggests pope leo xiv used tools like anthropic's claude to draft portions of his first encyclical on ai.
linch zhang and other analysts used pangram to analyze 'magnifica humanitas', finding significant sections, including 62% of the first chapter, were likely ai-generated. the detection is based on specific linguistic markers associated with ai models like claude, and the verifcation independently confirmed a 46% probability rating on a 2,000-word sample. while previous papal speeches and encyclicals rated as 100% human-written, this document breaks that pattern, raising questions about the vatican's use of automation in high-level communication. despite pangram's low false positive rate, the vatican has not yet commented on whether ai tools were used to draft the document, which was presented alongside anthropropic co-founder christopher olah.
