Outcome

Asked to fact-check a post claiming Bitcoin would 'surge 500%' based on a study, Claude for Chrome reported in about 2 minutes that the paper wasn't in any academic database, the 500% maths was wrong, a commenter said it was AI-generated, and the paper itself said it wasn't a prediction.

Poster says:About 2 minutes

Prompt Recreated prompt

The source didn't share its exact prompt, so we wrote this from what it describes.

Before you start, ask me 1–3 short questions about the details below and wait for my answers. Once I've answered, confirm the plan in one line and run the whole task start to finish.

Goal: Check whether a viral claim that cites a study is true.

Quick-check questions: Which post, and what exactly is being claimed?

What I'll give you:
- Link to the post ([URL])

Rules:
- Find the original paper in academic databases (e.g. Google Scholar) or on the publisher's site.
- Quote the exact sentence or figure the claim relies on, with a link.
- Recheck any numbers in the claim yourself.
- Check the date of the original post and the study.
- Give a verdict (supported, overstated or wrong) and explain it in two sentences.

Output: The verdict (supported / overstated / wrong), each finding with a link, and what the original source really says.

If my answers leave a gap, make a sensible choice, say what you assumed, and keep going.

You'll know it worked when: I can open every link and see the evidence for the verdict.

This prompt has blanks to fill in, like [URL]. We'll copy it instead of filling it in, so you can edit it before you send.

Our rewrite with extra checks. The poster didn't test it.

Before you start, ask me 1–3 short questions about the details below and wait for my answers. Once I've answered, confirm the plan in one line and run the whole task start to finish.

Goal: Check whether a viral claim that cites a study is actually supported by that study.

Questions to ask me first:
- Which post, and what exactly is the claim?
- Do you want a quick verdict or a full breakdown?

Inputs (fill in or confirm):
- Link to the post ([URL])
- My level of detail (quick verdict or full breakdown)

Rules:
- Quote the claim exactly as posted.
- Find the cited paper on the publisher's site or Google Scholar; confirm title, authors, year and journal.
- Find the specific sentence, table or figure the claim relies on and quote it with page or section.
- Recompute any numbers in the claim yourself.
- Check the study type (trial, observational, model) and sample size, and whether the claim overstates it.

If you get stuck: If the paper is paywalled, use the abstract and say what you couldn't check. If a login, CAPTCHA or two-step code appears, stop and ask me to handle it; never guess or store passwords.

Verify before you finish: Re-read your verdict against the quoted evidence.

Output: Verdict (supported, overstated, wrong, can't verify), the claim, the evidence quote, and a two-sentence explanation.

Done when: I can see exactly where the claim matches or departs from the paper.
