Sources & Methodology
Every incident, casualty figure, and territorial assessment in GrayZone resolves to a named, dated source. All conflicting reports are documented side-by-side rather than silently averaged.
Source Concentration & Empirical Baseline
96.8% Baseline Share6,869 of 7,099 total citations (96.8%) originate from the Council on Foreign Relations’ Nigeria Security Tracker (NST), which serves as the foundational empirical baseline for pre-2023 historical conflict data.
NST provides uninterrupted multi-year consistency tracking Boko Haram and ISWAP campaigns from 2011 to 2023, systematically cataloguing regional press dispatches.
Recent and real-time coverage transitions away from single-aggregator dependence, triangulating across operational communiqués (DHQ, NAF, Navy, Police), frontline OSINT networks (Zagazola Makama), and independent investigative journalism (Daily Trust, HumAngle, Premium Times).
Provenance tagging system
Every incident and casualty record on this platform carries a visible tag indicating the methodology and institutional origin of the claim:
Inclusion criteria
A recorded incident requires: a specific date (or a disclosed date range), a specific location resolvable to at least state + LGA, at least one named source with a publication date, and an original-words summary without verbatim reproduction of paywalled or protected copy.
Admiralty Grading System
Conflict tracking in asymmetric environments requires distinguishing verified ground truth from operational communiqués, propaganda, and unverified frontline rumors. GrayZone evaluates every conflict incident, maritime interdiction, and casualty figure using the NATO STANAG 2022 / Admiralty Code — a two-dimensional intelligence assessment standard evaluating Source Reliability (A–F) independently against Information Credibility (1–6).
A1 · Confirmed Ground Truth
Source is completely reliable and information is confirmed by independent physical, geolocated video/photographic evidence, or verified satellite sensor detections (such as NASA FIRMS thermal anomaly matches) corroborated by on-ground witnesses.
B2 · Corroborated Reporting
Source is usually reliable (established investigative outlets such as HumAngle, Daily Trust, Premium Times, Reuters) and the event is corroborated by independent accounts without material discrepancies.
C3 · Official Communiqué
Official press release or operational statement from military/security spokespersons (DHQ, NAF, Navy, Police). Classified C3 because official releases are subject to operational censorship and lack external verification.
D4 · Preliminary / Eyewitness Dispatch
First-hand eyewitness reports, local community distress messages, or preliminary social media dispatches currently undergoing verification. Displayed with caution to track emerging security events.
The Two-Dimensional STANAG 2022 Matrix
- A — Completely reliable: Direct institutional observer, audited sensor, satellite track
- B — Usually reliable: Accredited conflict journalist, vetted NGO monitor (HumAngle, ACLED)
- C — Fairly reliable: Official spokesperson release subject to operational bias
- D — Not usually reliable: Unvetted local account, partisan claim
- E — Unreliable: Demonstrated history of disinformation
- F — Cannot be judged: Untested new source
- 1 — Confirmed: Independent visual evidence, ground verification, multiple sources
- 2 — Probably true: Consistent with operational context, corroborated without conflict
- 3 — Possibly true: Plausible claim from single party, lacks independent confirmation
- 4 — Doubtful: Disputed casualties, contradictory local reporting
- 5 — Improbable: Contradicted by confirmed geographic or radar/satellite data
- 6 — Cannot be judged: Inadequate details to assess
