Methodology

Every article on npcrf.org follows the same verification method. It has three parts: identified primary sources, a mandatory sources section, and a public corrections policy.

Identified primary sources

Articles are built on primary sources wherever they exist: official records, legislation, court documents, original datasets, peer-reviewed research and contemporaneous documents. Each source is identified precisely, so that any reader can locate and check it.

Secondary sources (news reports, books, analyses) are used to provide context or to corroborate, not as the sole basis for a claim of fact. Anonymous or single-origin claims that cannot be independently verified are not presented as fact.

A sources section in every article

Every article ends with a Sources section listing each source used, with its URL and the date it was consulted. This section is mandatory: the claims in the text must be traceable to the sources in the list.

If a claim cannot be verified against an identified source, it is not published. When the available evidence is incomplete or disputed, the article states that openly instead of filling the gap.

Corrections

Errors are corrected as soon as they are identified, and changes made after publication are recorded visibly on the article itself:

• every article shows its original publication date; when it is revised, an updated date appears next to it;
• substantive corrections (anything that changes meaning, figures or conclusions) are itemized in a Corrections note on the article, with the date and a description of what changed;
• purely typographical fixes that do not alter meaning may be applied without a note.

To report an error, write to info@npcrf.org (see Contact). Reports are checked against sources, not against opinions, and are acted on regardless of who sends them.
