2017 Human Text Classified as AI-Generated
A persoenlich.com editorial by Christian Beck describes how a 2017 blog post he wrote was flagged as AI-generated by detectors. He reports an initial TextGuard result of 76% AI-generated and later notes TextGuard rated the same text 61% AI while Pangram judged it 100% human. The article summarizes many LinkedIn comments showing widespread mistrust of AI text detectors, with examples such as Martin Luther King Jr.'s speech being labeled highly AI-generated and genuine AI text sometimes labeled human. The piece criticizes detector reliability, highlights how detectors favor highly structured journalistic style, and warns about commercial practices that profit from humanizing content. Beck concludes that, for now, AI text detectors are unreliable.
Highlights unreliability of AI text detectors and the risk of false accusations and commercial 'humanizing' services; relevant to publishers, communications professionals, and education but not a platform policy change.

Pangram: Over 40% of LinkedIn Long Posts AI-Generated
Pangram Labs, maker of an AI-text detector, analysed social-media posts users actually encountered across platforms and found a high prevalence of AI-generated text. The study reports that more than 40% of LinkedIn posts longer than 250 words were classified as fully AI-generated. Pangram claims a 99.98% detection accuracy, supported by independent studies at the University of Maryland and the University of Chicago. Across the sampled platforms the average AI share was 13.8%, with longer posts more likely to be AI-generated; on X Pangram classified 25% of content as fully AI-generated and 23% as AI-assisted. LinkedIn has publicly commented on the rise of so-called "AI Slop" and said it will respond to the trend.
This Essay Is 10% AI-Generated
An a16z opinion essay (published 2026-08-13) examines cultural reactions to AI-generated writing, arguing that labelling text as “100% AI” functions as a social authorship marker. The piece discusses literary theory (Barthes, Foucault) to frame why authorship matters, highlights detection tools like Pangram and industry moves toward watermarking AI outputs, and describes stylistic tells of LLM-generated prose (token-prediction patterns, pushy qualifiers). The author says none of the words were directly generated by an LLM, but that they iterated ideas with “Sol 5.6” and estimates the piece is roughly 10% AI-influenced.
Study: AI-Generated Stories Rated More Engaging
A Villanova University study found that participants rated AI-generated short stories as more engaging and higher quality than comparable human-written stories. Participants read six short stories (three AI, three human) and were told whether each text was AI-generated, with researchers sometimes giving false information. The article also notes that LinkedIn faces a flood of AI-generated posts—an analysis tool, Pangram, labeled 41% of longer LinkedIn posts as fully AI-generated. Researchers including Deena Skolnick Weisberg say AI can already produce stories as good as or better than humans, while critics warn about training on large bodies of human-written text and ethical concerns.
