Public Sources Only
No non-public sourcing.
The site uses public reporting, official statements, specialist analysis, public data, and open observation. It does not solicit or rely on non-public information.
Methodology
How Sourced Signal works.
Open-source analysis. Human judgment. Strategic relevance. Sourced Signal uses public sources, confidence labels, source notes, model-assisted synthesis, and human review to keep published products focused and traceable.
Fact vs Assessment
Reported facts and judgment are separated.
Cards are written to distinguish what was reported from why it may matter for U.S. strategy or geopolitical risk.
Human Review
Editorial review is the publication gate.
Reviewed products do not publish directly from candidate queues. Claims involving casualties, attack attribution, nuclear issues, escalation, or social-only sourcing require extra caution before they should be treated as settled.
Publication Threshold
Not everything belongs in the brief.
Daily Brief editions use selective high-signal items, usually 6–8, fewer when signal is weak. Items must show clear relevance to U.S. strategy, economic statecraft, defense capacity, AI infrastructure, crisis escalation, or geopolitical risk.
Source Types Used
| Source type | How it is used |
|---|---|
| Official statement | Government, military, international organization, court, regulator, or central bank. |
| Established media | Major news outlets with editorial standards, corrections processes, and named reporting. |
| Specialist analysis | Think tanks, defense analysts, regional experts, trade publications, and technical research. |
| OSINT observation | Public imagery, geolocation, flight tracking, maritime tracking, and other observable public data. |
| Adversary or state media | Useful for official narratives, propaganda signals, and stated positions; treated cautiously. |
| Unconfirmed claim | An early claim that may matter but is not treated as fact. |
| Social discussion signal | Discussion from public platforms. Useful for discovery, never confirmation by itself. |
| Strategic document | Defense strategies, white papers, budgets, regulations, legislation, court filings, and official plans. |
Confidence Labels
| Level | Meaning |
|---|---|
| High | Multiple reliable sources or official confirmation; limited contradiction. |
| Medium | Credible reporting or official claim with partial corroboration. |
| Low | Single-source, unclear, early, or contested reporting. |
| Unconfirmed | Not treated as fact; included only as a signal requiring verification. |
How AI Is Used
AI helps organize the work.
Automation helps collect public information, group related items, and draft summaries from selected inputs. AI is assistive, not decisive: deterministic validation and human judgment decide what belongs in a public product, how confident the site should be, and why the item matters.
Correction Policy
If an item is inaccurate, mislabeled, or missing important context, Sourced Signal will update the item and note the correction where appropriate.
