Social Media Reacts To Pope Leo’s AI Encyclical With ‘Dune’ Memes
Researchers said 40% to 100% of some paragraphs looked AI-generated, raising questions about transparency in the Vatican’s first AI-focused encyclical.
- Following Pope Leo XIV's May 25, 2026, release of the encyclical Magnifica Humanitas on artificial intelligence, researchers flagged portions as potentially AI-generated using the Pangram detector. The Vatican has not publicly commented on the claims.
- Analysts shared findings on forums estimating an aggregate of 46 percent machine-generated content, with some opening chapters reaching 62 percent. Specific passages scored between roughly 40 percent and 100 percent likelihood of AI authorship according to the detector.
- Stylistic markers consistent with Anthropic's Claude appeared throughout, notably the word "genuinely" used 9 times versus zero in similar-length previous encyclicals. Comparisons to earlier papal writings, which registered as entirely human-authored, suggested potential machine assistance in drafting.
- Tech investor David Sacks and AI researcher Yoshua Bengio offered mixed reactions, with Sacks questioning governance safeguards and Bengio endorsing papal dialogue on AI risks. Critics argued unverified AI authorship could undermine the document's moral authority in institutional communications.
- The episode highlights the need for transparency norms in AI-assisted institutional writing, as detection tools and public analysis enable accountability without definitive proof. Observers urged the Vatican and similar institutions to establish disclosure standards for high-stakes communications.

It is a power that has even exceeded that which many governments in the world have.
Did Pope use AI to write his anti-AI encyclical? The internet is debating
Pope Leo XIV’s first major encyclical urges governments to slow down artificial intelligence development, warning of misinformation, conflict and job disruption. But the internet is now focused on a different question altogether: was the Vatican’s anti-AI document itself partially written using AI tools like Claude or ChatGPT?
