What you will be able to do
By the end of this learning path, you should be able to identify the claims in an AI answer that require checking, choose appropriate sources, trace quotations and statistics to their origin, recognize weak or conflicting evidence, and record a conclusion another person can review.
Module 1
Identify what needs verification
Do not try to verify an entire paragraph at once. Break the answer into individual claims. A claim is a statement that could be supported, contradicted, or updated by evidence.
Prioritize by consequence and decay
- High consequence: health, legal, financial, safety, employment, or compliance decisions.
- Fast-changing: prices, product features, software versions, officeholders, schedules, laws, and policies.
- Precise: names, dates, quotations, percentages, rankings, and calculations.
- Suspiciously complete: references, studies, or links that sound plausible but were not requested from a known source.
“The program launched in 2024, costs $29 per month, and reduced processing time by 37% in a Stanford study.”
Launch date; current price; existence of the study; Stanford’s involvement; the 37% result; and whether the study applies to this situation.
Quick exercise
Take one AI answer you recently received. Underline every number, date, named person, quotation, causal claim, recommendation, and current product statement. Mark each as low, medium, or high consequence.
Knowledge check: Which claim should you verify first?
“This supplement is safe with your prescription.” It could affect health and requires a qualified, current source. A harmless wording suggestion can wait.
Module 2
Choose evidence that fits the claim
The best source depends on the question. A company’s official documentation may be appropriate for its current product features, but independent evidence is stronger for claims about effectiveness. A summary article can help you understand a topic, but it should not replace the original rule, study, dataset, or announcement when the decision matters.
| Claim | Start with | Then check |
|---|---|---|
| Current product feature or price | Official product or pricing page | Update date, plan, region, and limitations |
| Law, regulation, or government deadline | Official agency or legislative source | Jurisdiction, effective date, and amendments |
| Scientific or medical claim | Original research and authoritative health guidance | Study quality, population, date, and professional advice |
| Statistic | Original dataset or report | Definition, sample, period, and denominator |
| Quotation | Transcript, recording, filing, or original publication | Exact wording and surrounding context |
Quick exercise
For three claims from Module 1, write the ideal primary source before searching. This prevents the first convenient search result from becoming your standard of proof.
Knowledge check: Is a search-result snippet enough evidence?
No. Open the source. The snippet may omit context, show old text, or combine words that do not support the claim.
Module 3
Trace sources, dates, and quotations
An AI-generated citation can be real, inaccurate, or entirely fabricated. Confirm that the source exists, that the author and title match, and that the source actually supports the nearby statement.
Use the SIFT check
- Stop: pause before accepting or sharing the claim.
- Investigate the source: identify who published it and why.
- Find better coverage: look for an authoritative or independent source.
- Trace to the original: locate the underlying study, filing, transcript, dataset, or announcement.
Check freshness and scope
Record the publication or update date. Confirm that the evidence covers the same product version, country, population, and time period as the AI answer. A true statement from two years ago may be misleading today.
“List each factual claim in this answer. For every claim, state what type of primary source would verify it. Do not invent links or citations. Label anything you cannot support as unverified.”
This prompt organizes the work, but it does not perform the verification for you. Open and evaluate the sources yourself.
Knowledge check: A cited article exists. Is the claim verified?
Not yet. Confirm that the article contains the stated information, represents it accurately, and is sufficiently current and authoritative for the decision.
Module 4
Compare evidence and resolve conflicts
Two sources may disagree because they use different definitions, dates, populations, methods, or incentives. Do not settle a conflict by counting links. Compare the evidence behind them.
Create a small evidence table
| Source | Supports what? | Date and scope | Limitations |
|---|---|---|---|
| Primary source | Exact claim or data point | Version, region, period | Missing context or self-interest |
| Independent source | Confirmation or criticism | Audience and method | Secondary reporting or small sample |
| Contradictory source | Alternative result | Different conditions | May not address the same question |
If reliable evidence remains mixed, say so. “Evidence is inconclusive” is a useful finding. Do not force certainty merely because the original AI answer sounded certain.
Red flags
- The exact statistic appears only in AI-generated summaries.
- Many websites repeat the same wording but cite no original source.
- The source title is real but the quoted passage is absent.
- The answer combines results from different populations or time periods.
- The source has been corrected, retracted, superseded, or archived.
Knowledge check: Five blogs repeat a statistic and one official dataset disagrees. Which carries more weight?
The original dataset generally carries more evidentiary weight. Check definitions and dates, then determine whether the blogs copied one another or interpreted the data differently.
Module 5
Document and communicate your conclusion
A fact-check should make the reasoning visible. Record the original claim, sources consulted, relevant dates, what each source establishes, remaining uncertainty, and your conclusion.
Use calibrated conclusions
- Verified: strong, current evidence directly supports the claim.
- Mostly accurate: the central point is supported, but wording or context needs correction.
- Unverified: you could not find adequate evidence.
- Outdated: the claim was once accurate but no longer reflects current information.
- Misleading: technically true elements create an incorrect overall impression.
- False: reliable evidence directly contradicts the claim.
Capstone exercise
Choose a low-risk AI answer containing at least five factual claims. Build a claim list, assign a consequence level, identify the ideal source for each, and verify at least three claims. Create an evidence table and write a five-sentence conclusion explaining what you would keep, correct, remove, and still treat as uncertain.
Keep a verification record
For work you may revisit or share, save a short record with six fields: the exact claim, why it matters, the source URL or document title, the source date, the evidence you found, and your conclusion. Copy the relevant sentence into your notes rather than saving only a link. Web pages can change, and a future reviewer needs to know what you saw and why it supported the decision.
For example, suppose an AI answer says that a software feature is included in every plan. Your record might show that the official pricing page lists the feature only for two paid plans, while a help article says access is still rolling out by region. The responsible conclusion is not simply “false.” A more accurate conclusion is: “The claim is misleading because availability depends on the plan and region; confirm the account’s current feature list before purchase.” This wording preserves what the evidence actually establishes.
Claim: [Copy the exact statement.]
Consequence: [What could happen if it is wrong?]
Best source: [What authority or original evidence should answer it?]
Evidence: [Record the relevant wording, date, scope, and link.]
Conflicts or limitations: [What remains uncertain?]
Conclusion: [Verified, mostly accurate, unverified, outdated, misleading, or false.]
Final checklist
- Did I separate the answer into individual claims?
- Did I prioritize consequential and fast-changing information?
- Did I open the source rather than rely on a snippet or AI summary?
- Did I trace important claims to primary evidence?
- Did I check dates, scope, definitions, and conflicts?
- Does my conclusion reflect uncertainty honestly?
- For high-impact decisions, did I consult an appropriate professional or authority?
Knowledge check: When should you reject an otherwise useful AI answer?
Reject or substantially revise it when central claims are fabricated, contradicted by strong evidence, dangerously outdated, or impossible to verify for a consequential decision.
Frequently asked questions
Can I ask the same AI to fact-check its own answer?
You can ask it to identify claims, assumptions, and possible sources, but that is not independent verification. The system may repeat the same mistake or invent supporting details.
Are AI citations trustworthy?
Treat them as leads. Confirm that each source exists, opens correctly, matches the stated author and title, and directly supports the claim.
How many sources do I need?
There is no universal number. One authoritative primary source may settle a straightforward fact; a disputed or consequential claim may require multiple independent sources and expert interpretation.
Should I trust official sources automatically?
Official sources are usually best for their own rules, data, prices, and product details. Still check dates, jurisdiction, definitions, and whether an independent source is needed to evaluate performance or impact.
What if I cannot verify a claim?
Label it unverified, remove it from consequential work, or rewrite the conclusion to state the uncertainty. Lack of contradictory evidence is not proof.
