Domain-specific¶
- Benford's Law
- The forensic application exploits a systematic human failure: people inventing numbers cannot reproduce the Benford curve — in Hill's 1988 random-number guessing experiments the leading digits of made-up six-digit numbers were not uniform at all but leaned the Benford way, digit 1 appearing far more often and digits 8 and 9 far less often than an even spread would give, while the second digits came out much more uniformly distributed than the first — so fabricated records depart detectably from the expected digit frequencies in a way that flags them for deeper investigation
This sourceTurning that gap into an audit test is Nigrini's work, not Hill's.

Verification¶
Does it exist? Confirmed. This work's DOI resolves to a registered record, which fixes its identity. That is all it fixes.
Does it back the claim? Read against the text for 1 of 1 citation: 1 supported in part. Each verdict is shown under its citation below, with what in the work backs the sentence.
Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
