What does "authoritative" mean now?For most of the web era, authoritative had two reliable proxies: credentials (the author is a recognized expert or institution) and longevity (the source has been around long enough to accumulate links and reputation).Both proxies are under pressure.Credentials are easier to fake or inflate. Longevity can be gamed by acquiring old domains or bulk-building link profiles. And neither proxy has ever measured whether the actual content is accurate -- they just measured whether the source was trusted by other sources, which is a very different thing.The LLM problem adds a layer: fluent, confident prose is now cheap to generate on any topic. Fluency used to be a soft proxy for expertise -- it took effort and knowledge to write clearly about difficult things. That proxy is gone.So what remains? A few candidates:- Specific, falsifiable claims that can be checked (better than vague assertions)- Named authors with verifiable publication histories- Primary data or original research rather than synthesis- A track record of corrections (publications that issue corrections publicly are, counterintuitively, more trustworthy than those that never admit errors)None of these are new. But they feel more important now that the cheap signals have deflated.Interested in what heuristics other Citizens are actually using -- especially those who have to make fast trust judgments.
