Methodology
Analytical frameworks, confidence standards, and essay structure guide
EXOPOLOSI applies established intelligence community analytical frameworks to exopolitical research. This page documents our methodology in full so that readers can evaluate our work and contributors can produce assessments that meet our standards.
Confidence Levels
Every key judgment carries a confidence level. These are not expressions of opinion — they reflect a structured evaluation of evidence quality and analytical agreement.
| Level | Meaning | Criteria |
|---|---|---|
| High | Strong basis for the judgment | Multiple independent, reliable sources corroborate; analytical logic is sound with few assumptions; alternative explanations have been thoroughly considered and are significantly less plausible |
| Moderate | Reasonable basis with some gaps | Credible sources support the judgment but may lack full independence or corroboration; some assumptions are required; alternative explanations exist but are assessed as less likely |
| Low | Tentative, evidence is limited | Sources are limited, uncorroborated, or of uncertain reliability; significant assumptions are required; alternative explanations remain plausible |
Admiralty (NATO) Source Grading System
We evaluate sources along two independent dimensions: source reliability and information credibility. These are combined into a two-character grade (e.g., B2).
Source Reliability
| Grade | Label | Description |
|---|---|---|
| A | Completely Reliable | Source has a history of complete accuracy; no doubt of authenticity, trustworthiness, or competency |
| B | Usually Reliable | Source has a history of providing valid information most of the time; minor doubt about authenticity, trustworthiness, or competency |
| C | Fairly Reliable | Source has occasionally provided valid information; some doubt about authenticity, trustworthiness, or competency |
| D | Not Usually Reliable | Source has provided valid information infrequently; significant doubt about authenticity, trustworthiness, or competency |
| E | Unreliable | Source has a history of invalid information; lacks authenticity, trustworthiness, and competency |
| F | Cannot Be Judged | No basis exists for evaluating the reliability of the source |
Information Credibility
| Grade | Label | Description |
|---|---|---|
| 1 | Confirmed | Confirmed by other independent sources; logical in itself; consistent with other information |
| 2 | Probably True | Not confirmed; logical in itself; consistent with other information on the subject |
| 3 | Possibly True | Not confirmed; reasonably logical in itself; agrees with some other information |
| 4 | Doubtfully True | Not confirmed; possible but not logical; no other information on the subject |
| 5 | Improbable | Not confirmed; not logical in itself; contradicted by other information |
| 6 | Cannot Be Judged | No basis exists for evaluating the validity of the information |
Example usage: A claim graded B2 comes from a usually reliable source and the information itself is probably true but not independently confirmed. A claim graded D5 comes from a source that is not usually reliable and the information is improbable.
Witness and Evidence Probability (WEP) Scale
For cases involving witness testimony and physical evidence, we use an expanded evaluation framework:
| Score | Assessment | Description |
|---|---|---|
| 9-10 | Virtually Certain | Multiple independent high-quality sources; physical evidence; official acknowledgment |
| 7-8 | Highly Probable | Multiple credible witnesses; some physical evidence or official documentation |
| 5-6 | Probable | Credible testimony with partial corroboration; circumstantial physical evidence |
| 3-4 | Possible | Single credible witness or multiple witnesses of uncertain reliability; no physical evidence |
| 1-2 | Unlikely | Uncorroborated claims from unvetted sources; inconsistencies present |
| 0 | Cannot Assess | Insufficient information to form any judgment |
Estimative Language
We follow IC conventions for expressing probability:
| Term | Approximate Probability |
|---|---|
| Almost certainly | >95% |
| Highly likely / Very probable | 80-95% |
| Likely / Probable | 60-80% |
| Roughly even chance | 40-60% |
| Unlikely / Improbable | 20-40% |
| Highly unlikely / Very improbable | 5-20% |
| Almost certainly not | <5% |
Rules for usage:
- Always use “we assess,” “we judge,” or “we estimate” — never “I think” or “I believe”
- Never express absolute certainty: even high-confidence judgments acknowledge the possibility of being wrong
- Always pair estimative language with a confidence level: “We assess with moderate confidence that…”
Essay Structure Guide
Every EXOPOLOSI assessment follows a standardized structure designed for clarity and analytical rigor. This section documents each required component.
1. BLUF (Bottom Line Up Front)
The opening section states the core conclusion immediately. A BLUF should:
- State the primary finding or assessment in 2-4 sentences
- Include the confidence level
- Reference the basis for the judgment (e.g., “based on analysis of three independent sources…”)
- Allow a reader to understand the key takeaway without reading further
Use the bluf shortcode:
{% bluf() %}
We assess with **moderate confidence** that [conclusion]. This judgment is based on [evidence basis]. [Key qualification or caveat].
{% end %}
2. Background
Provides the context a reader needs to understand the analysis. Should be factual and descriptive, not analytical. Cite sources with Admiralty grades.
3. Source Evaluation
Explicitly grade key sources using the Admiralty system. Use the source_grade shortcode for inline grades:
{% source_grade(grade="B2") %}
4. Analysis
The core analytical section. Use callout shortcodes to highlight important elements:
key_finding— for significant analytical conclusions (blue border)assessment— for formal assessments with confidence levels (green border)caution— for important caveats or limitations (amber border)unverified— for claims that cannot be verified (red border)methodology_note— for methodological explanations (gray border)
Use the confidence_badge shortcode for inline confidence markers:
{%/* confidence_badge(level="High") */%}
5. Alternative Hypotheses
Required for every assessment. Consider a minimum of three competing explanations:
- State each hypothesis clearly
- Evaluate the evidence for and against each
- Assess relative plausibility
- Explain why the primary assessment is favored
6. Forecast
When applicable, provide probabilistic outcomes in table format:
| Outcome | Probability | Timeframe |
|---|---|---|
| Description | Estimative term | Period |
7. Key Judgments
A numbered summary list of all key findings and assessments made in the document. Each item should include its confidence level. This section allows readers who have read the BLUF to quickly scan all subordinate judgments.
Sidenotes
Use sidenotes for supplementary information that would disrupt the main text flow:
{%/* sidenote(id="1") */%}
Supplementary context that enriches but is not essential to the main argument.
{% end %}
On wide screens, sidenotes appear in the margin. On mobile, they are expandable inline elements.
