Documentary Evidence

Documentary Evidence

A skill for building arguments through systematic citation of primary sources - letting documents speak louder than claims.

When to Use

• When making claims that will be contested
• When authority of the argument should rest on evidence, not the arguer
• When permanent record matters more than persuasive style
• When opponents can be refuted by their own documents

Inputs

Workflow

Step 1: Phase 1: Identify What Needs Proving

Break your claim into components:

• What specific facts must be established?
• What causal connections must be demonstrated?
• What objections must be preempted?
• What standards of proof does your audience expect?

Each component needs its own documentary support.

Step 2: Phase 2: Locate Primary Sources

Find original documents:

• Official records (government, corporate, organizational)
• Internal communications (memos, emails, meeting notes)
• Public statements (speeches, press releases, testimony)
• Legal documents (filings, contracts, court records)
• Academic sources (peer-reviewed studies, data)
• Contemporaneous accounts (journalism, reports)

Primary sources are harder to dismiss than secondary interpretation.

Step 3: Phase 3: Evaluate Source Quality

Assess each source:

• Is it authentic? (Could it be forged or misattributed?)
• Is it complete? (Has it been selectively quoted or redacted?)
• Is it contemporaneous? (Was it created at the time of events?)
• Is it authoritative? (Who created it and why?)
• Is it accessible? (Can others verify it?)

Weak sources undermine even strong arguments.

Step 4: Phase 4: Build the Chain

Connect sources to claims:

• Each factual claim should have explicit source citation
• Complex claims need multiple supporting sources
• Anticipate objections and address with additional sources
• Show your work - readers should be able to follow the chain

The argument should be traceable from claim to source.

Step 5: Phase 5: Present Systematically

Structure for maximum clarity:

• State claim, then provide supporting evidence
• Use consistent citation format
• Quote directly when possible rather than paraphrasing
• Acknowledge limitations and gaps
• Distinguish certain from probable from speculative

Step 6: Phase 6: Preserve the Record

Ensure sources remain available:

• Archive sources locally (documents disappear)
• Use persistent links where possible
• Note access dates for online sources
• Consider how adversaries might challenge sources

The argument is only as permanent as its sources.

Output Format

A documentary evidence compilation including:

1. Claims stated precisely
2. Sources for each claim with quality assessment
3. Citation chain showing claim-to-source connection
4. Acknowledgment of gaps and limitations
5. Preservation notes
6. Anticipated objections addressed through documentation

Constraints

• Documents can be misinterpreted - context matters
• Some claims can't be documented (classified, destroyed, never written)
• Over-documentation can obscure the argument
• Adversaries may challenge source authenticity
• Documentary style can be less engaging - balance with accessibility

Outputs

Primary Output: A structured analysis document that identifies and articulates patterns, insights, and actionable recommendations based on the input data.

Format:

## Analysis: [Topic]

### Key Findings
- [Finding 1]
- [Finding 2]
- [Finding 3]

### Recommendations
1. [Action 1]
2. [Action 2]
3. [Action 3]

Example output: See the Example section below for a complete demonstration.

Additional Notes

Best practices:

• Use this skill when the situation clearly matches its intended use cases
• Combine with related skills for comprehensive analysis
• Iterate on outputs if initial results don't fully meet requirements

Common variations:

• Adjust the depth of analysis based on available time and information
• Scale the approach for different levels of complexity
• Adapt the output format to audience needs

When to skip this skill:

• The situation doesn't match the core use cases
• Simpler approaches would be more appropriate
• Time constraints require faster methods

Example

Input: Document the claim that Company X knew about product danger before public disclosure

Output: "Claim: Company X had internal evidence of danger by [date], [years] before public acknowledgment. Source 1: Internal memo dated [date] (obtained through [litigation/FOIA]) showing test results indicating danger. Quality: Authenticated in court proceedings, complete document, contemporaneous. Source 2: Email thread from [date] showing executive awareness of memo. Quality: Produced in discovery, partial (some redactions), direct evidence of knowledge. Source 3: Public statement from [later date] claiming no evidence of danger. Quality: Publicly available, establishes contradiction. Source 4: Expert testimony that test results memo would have been understood as indicating danger. Quality: Qualified expert, but interpretation rather than fact. Chain: Memo proves knowledge of data → Email proves executive awareness → Statement proves public denial → Timeline proves gap. Limitations: Cannot document every executive's awareness, only those in email chain. Preserved: All documents archived locally, court filings available through [database]."

Integration

Works with:

• documentation-as-resistance: Documentary evidence is a form of documentation
• evidence-authentication: Assessing source credibility
• disclosure-calculus: Documents may come from whistleblowers
