Three distinct phases emerge as synthetic content accumulates in our information systems over time. Tue, 17 Mar 2026 00:00:00 GMT https://fairgradient.web.app/blog/ln2 https://fairgradient.web.app/blog/ln2 If AI-generated content is epistemically different from human content, can't we just detect and filter it? A look at why detection tools face fundamental challenges as language models keep improving. Tue, 03 Mar 2026 00:00:00 GMT https://fairgradient.web.app/blog/ln3 https://fairgradient.web.app/blog/ln3 A counterintuitive proposition: one of the most valuable properties of training data is human error — not random error, but the structured, systematic, informative errors Gerd Gigerenzer called 'good errors.' Fri, 20 Feb 2026 00:00:00 GMT https://fairgradient.web.app/blog/ln4 https://fairgradient.web.app/blog/ln4 When people explain model collapse, they reach for the photocopy-of-a-photocopy analogy. It captures iterative degradation — but it frames the problem in a way that limits how we think about solutions. Tue, 17 Feb 2026 00:00:00 GMT https://fairgradient.web.app/blog/ln5 https://fairgradient.web.app/blog/ln5 There's been significant attention on model collapse — AI models trained on AI output that gradually degrade. But there's a more consequential question underneath it.
