Source Evaluation Criteria
Source Evaluation Criteria
Parent: Sources & Bibliography · Methodology
This page defines the concrete rules used to admit, rank and label sources on the site. It is the operational companion to the high-level source policy stated in the Methodology.
1. Four-Tier Hierarchy
| Tier | Label used in text | Typical material | Treatment |
|---|---|---|---|
| 1 | Primary / near-primary | Official sanctions lists (OFAC, UK, EU, Canada, Australia); court judgments and filings available in open repositories; formal government reports; statistical releases from UNODC, World Bank, IMF and comparable bodies | Highest weight. Can support a claim almost alone if the document is clear. |
| 2 | Secondary – Investigative / Academic | Monographs with full source apparatus (e.g. Dawisha 2014, Galeotti 2018); OCCRP and comparable consortium investigations; GI-TOC reports; peer-reviewed articles and university-press books; long-form investigations by outlets with transparent editorial standards | High weight. Preferred basis for structural claims. |
| 3 | Secondary – Analytical | Think-tank reports and expert assessments (Atlantic Council, Brookings, Chatham House, Lowy Institute, RUSI, etc.); clearly labelled expert commentary | Medium weight. Always signalled as “assessment by…” or “secondary analysis”. Cannot be the sole support for a contested factual claim. |
| 4 | Excluded | Anonymous social-media posts, unverified Telegram or closed-channel material, single-source rumour, material that cannot be independently located and verified by a third party | Never used as the sole or primary basis for any claim on the site. |
2. Practical Tests Applied to Every Source
Before a source is admitted into the bibliography or used to support a knowledge unit, the following checks are performed:
- Locatability — Can a reader independently retrieve the source (or a stable archived version) without special access?
- Transparency of method — Does the source itself disclose how it obtained its information, or is the method opaque?
- Corroboration potential — Is the claim also present (even partially) in at least one other independent Tier-1 or Tier-2 source, or is it unique?
- Conflict signalling — If the source is known to conflict with other high-quality sources on the same point, is that conflict noted?
- Date and context — Is the temporal scope of the claim clear? Outdated material is not presented as current without explicit qualification.
3. Labelling Conventions in Text
- Direct documentary support → neutral factual phrasing + citation.
- Secondary consensus across multiple Tier-2 sources → “documented in the secondary literature” or equivalent + multiple citations.
- Single Tier-3 assessment → “according to [author/organisation]” or “assessment by…”.
- Contested quantitative estimates → range or “estimates vary; open sources cite figures from X to Y”.
- Absence of evidence → never treated as evidence of absence.
4. Preference for Structural Over Sensational
When two sources of comparable tier exist, preference is given to the one that:
- illuminates under-emphasised structural mechanisms, routes or historical continuities, or
- synthesises material that is otherwise scattered across paywalled or language-isolated publications.
High-visibility individual scandals already exhaustively covered in mainstream English- and Russian-language media receive lower priority for new synthesis unless they illuminate a structural pattern that is still under-documented on the site.
5. Language and Access Notes
Sources are accepted in any language provided a stable public location exists. English and Russian primary/secondary material is preferred for accessibility to the bilingual audience, but high-quality sources in other languages are not excluded. Access notes (paywall, archive, PDF availability) are recorded in the master bibliography where useful.
