Learn verify

Trust is engineered. Check the claim before it is taught as fact.

When to run

• Empirical, historical, bibliographic, or API/tool claims
• Named theorems, identities, or "standard facts" you cannot reconstruct
• Anything you were about to present with unearned certainty

Skip a full search only when you can derive the statement in-session and the learner does not need an external citation. Still say that it was derived, not sourced.

Method

1. Write the claim in one falsifiable sentence.
2. Fetch or search primary-ish sources (paper, textbook, official docs, standard reference). Do not cite a URL you did not open.
3. Quote or paraphrase the supporting line. Note edition / year if it matters.
4. Mark disagreements. Prefer the source the field actually uses.
5. Return a verdict.
