When Bard got its own
telescope wrong

Google's flagship Bard launch demo — a single promotional GIF — claimed the James Webb Space Telescope took the first pictures of an exoplanet. Astronomers caught it within hours: the Very Large Telescope did that in 2004. Alphabet lost $100B in market cap in a day.

The launch demo answered a question that wasn't asked correctly

On February 6, 2023, Google announced Bard — its answer to ChatGPT — with a promotional GIF posted to Twitter. The GIF showed Bard responding to the prompt: "What new discoveries from the James Webb Space Telescope can I tell my 9 year old about?"

Bard's response included three bullet points. One of them read: "JWST took the first pictures of a planet outside our solar system." It was a clean, confident sentence — exactly the kind of factoid a 9-year-old would remember.

It was also false. The first direct images of an exoplanet were captured in 2004 by the Very Large Telescope (VLT), operated by the European Southern Observatory in Chile. JWST didn't launch until 2021. Astronomers on Twitter spotted the error within hours of the announcement.

Two days later, on February 8, Alphabet's stock dropped roughly 9%, wiping out about $100 billion in market value. Microsoft — which had launched its Bing/ChatGPT integration the week before — gained ground in the AI race. Bard's launch event is now studied as a case of how a single unverified sentence in a demo can cost a company its narrative.

Feb 6, 2023
Google announces Bard. Positioned as a ChatGPT competitor. A launch GIF demo is prepared with a sample question about JWST discoveries.
Feb 7, 2023
Demo goes live. Bard responds: "The JWST took the first pictures of a planet outside our solar system." This is false — the VLT did it in 2004.
Feb 8, 2023
Astronomers catch it. Dr. Bruce Macintosh (Stanford) and others post the correction on Twitter within hours.
Feb 8, 2023
Stock crashes. Alphabet drops ~9% in a single day. Approximately $100 billion in market cap erased.
Aftermath
Bard launch delayed. Google's AI event underwhelms. Microsoft/Bing gains ground. A single fact-check would have cost $0.015.

What new discoveries from the James Webb Space Telescope can I tell my 9 year old about?

B
Factual error

JWST took the first pictures of a planet outside our solar system.

These exoplanets were only discovered in 2004.

Highlighted text = false attribution. The first direct images of an exoplanet were taken by the VLT in 2004, not JWST.

One token of human review to fact-check the claim

"NASA's own website confirms that the VLT took the first direct images of an exoplanet in 2004 — two decades before JWST began operations."

Three review criteria that would have caught this

Each criterion below maps to a real review task you can configure in the sample builder. A certified reviewer checks every factual claim against primary sources before a response ships — even in a marketing demo.

FACT-001

Verify scientific claims against primary sources

Every scientific or technical claim must be checked against a primary source — a peer-reviewed paper, an agency press release, or an official mission archive. A reviewer would have hit NASA's exoplanet archive and found the VLT attribution in seconds.

Reviewer instruction
"Is each scientific claim sourced? Check NASA/ESO mission archives and peer-reviewed literature. If no primary source confirms the claim → FAIL with reason 'unsourced scientific claim'."
FACT-002

Cross-reference "first" or "only" superlative claims

Superlatives are the highest-risk factual claims. Any sentence containing "first," "only," "largest," or "earliest" is automatically routed for priority verification. The reviewer must find the prior record-holder before the claim can ship.

Reviewer instruction
"Flag every superlative (first/only/largest). For each, identify the prior record-holder. Return FAIL if a confirmed earlier instance exists."
FACT-003

Check historical records for priority claims

When a claim asserts that one instrument, person, or organization achieved something, the reviewer checks the historical record for who actually did it first. In this case, the VLT's 2004 imaging would have surfaced immediately and blocked the claim.

Reviewer instruction
"For any priority claim (X did Y first), search the historical record for prior instances. Severity: CRITICAL for launch/marketing content."
