A source can be honest, useful, and still too interested, too far from the record, or too narrow for the claim it is being asked to support. The reader's job is to identify what role each source is playing before accepting the story's frame.
This map works for news stories, research reports, dashboards, vendor claims, and advertising measurement readouts. It does not label sources as good or bad. It separates access, expertise, incentive, and evidence so a reader can keep confidence proportional to the source trail.
A practical example: a campaign vendor sends a report saying exposed households converted 18% more often. That sentence may be useful, but it does not tell you whether the vendor measured a randomized comparison, matched people who were already likely to buy, or counted platform-visible activity as a sale. Map the vendor's role, the advertiser's outcome record, the platform's exposure rule, and the missing comparison before the number changes a budget.
The source role map
Start by assigning each quoted or cited source a role. The role tells you what the source can help establish and what extra checks the claim still needs.
| Source role | Useful for | Ask before trusting | Weak use |
|---|---|---|---|
| Primary record owner | Showing what was filed, counted, published, logged, or formally decided. | Does the story show the record scope, date, definition, and denominator? | Using the record's existence as proof of the broadest interpretation. |
| Direct participant | Confirming firsthand experience, sequence, statements, and incentives. | Which parts are observed facts, memory, interpretation, or advocacy? | Treating one participant's account as the full population or final cause. |
| Affected party | Explaining lived impact, operational details, and missing practical context. | Is the experience representative, illustrative, or an outlier? | Letting the strongest anecdote stand in for the denominator. |
| Independent subject expert | Explaining mechanism, method, precedent, and uncertainty. | Is the expertise directly related to the claim, and is the evidence basis visible? | Using authority to replace the primary record or measurement method. |
| Research producer | Explaining sample, model, survey, or analysis choices. | Who funded the work, who owns the data, and what limitations are disclosed? | Treating a method-bearing report as broader proof than the method supports. |
| Sponsor or vendor | Clarifying product design, business logic, study objective, or reported metric definition. | Does the article separate sponsor interest from method evidence? | Letting the party with the strongest stake supply both claim and conclusion. |
| Trade group or advocacy organization | Finding stakeholder positions, policy arguments, member data, and issue framing. | Whose interests are represented, and what counter-source should be visible? | Presenting an organized position as neutral consensus. |
| Platform or data owner | Defining eligible inventory, users, impressions, outcomes, match rules, and reporting limits. | What cannot be independently observed, audited, or compared? | Converting platform-visible activity into causal impact language. |
| Anonymous or background source | Providing narrow factual leads, process context, or documents that can be checked another way. | Why is anonymity needed, and does the article corroborate the claim? | Letting unnamed interpretation carry motive, scale, or causal judgment. |
| Secondary analyst or commentator | Orienting readers, identifying patterns, and comparing public material. | Does the analysis link back to inspectable records and method notes? | Replacing the original record with a confident summary. |
The incentive pass
Incentive is not a dismissal. It is context a reader needs before deciding whether a source is carrying facts, interpretation, or a desired outcome.
Financial incentiveThe source benefits if a product, category, service, investment, or campaign is viewed favorably. Look for independent denominators, method notes, and outcome definitions.
Reputational incentiveThe source benefits if a prior decision, forecast, investigation, strategy, or public position appears correct. Look for disconfirming context and error boundaries.
Political or advocacy incentiveThe source benefits if readers accept a policy frame, moral frame, or urgency frame. Look for definitions, base rates, omitted groups, and response parity.
Access incentiveThe source has documents, logs, data, or insider context other sources lack. Look for corroboration, narrow wording, and whether access is being upgraded into conclusion.
Method incentiveThe source built the metric, model, survey, or dashboard being discussed. Look for validation, uncertainty, comparison rules, and where the method cannot observe the counterfactual.
What each role can support
| Claim type | Strong source mix | Missing-context risk |
|---|---|---|
| Something happened | Primary record plus direct participant or official statement. | The event is real, but scale, representativeness, or cause is still unsupported. |
| A pattern is increasing | Time series, denominator, method note, and comparison period chosen before interpretation. | A convenient start date makes ordinary variation feel exceptional. |
| A group believes something | Survey disclosure with sample source, wording, field dates, weighting, and uncertainty. | A stakeholder quote or small sample is treated as public consensus. |
| A product or campaign worked | Decision-relevant outcome, comparison rule, exposure quality, holdout or model diagnostics, and uncertainty. | Selection, prior intent, attribution, or matched activity is promoted into lift. |
| A policy or business decision caused a result | Timeline, mechanism, counterfactual, denominator, and alternative explanations. | Timing is treated as causality because the source role fits the desired frame. |
| A report proves a category trend | Report method, data universe, sponsor role, base period, exclusions, and external benchmark. | Vendor or sponsor evidence is broadened beyond its own measured universe. |
Standards that sharpen the map
This map is an editorial decision aid, not a legal test or a substitute for subject-matter review. The Society of Professional Journalists Code of Ethics is a useful journalism boundary because it connects source work to verification, source identification, access to source material, and disclosure of unavoidable conflicts. It does not certify a source or settle a disputed claim.
For public survey claims, the AAPOR disclosure standards are more specific: inspect the sponsor and researcher, population, recruitment, mode, field dates, sample size and precision, wording, weighting, quality procedures, and limitations. Missing disclosure narrows what the result can support; disclosure alone is not proof of representativeness.
For endorsements or sponsored promotional statements, the Federal Trade Commission’s endorsement guidance treats a relationship that could affect how people evaluate an endorsement as a material connection that should be disclosed. That is a disclosure boundary, not a general rule that an interested source is false.
| Map dimension | Reader inspection | Useful standard anchor |
|---|---|---|
| Proximity and accountability | Can the reader reach the original record, full report, transcript, or method note, and can the source be identified? | SPJ source access and verification |
| Survey completeness | Are the population, recruitment, dates, mode, sample size, instrument, weighting, quality checks, and limitations visible? | AAPOR disclosure standards |
| Incentive disclosure | Would a reasonable reader change the weight given to the claim if the sponsor, payment, employment, or other relationship were known? | FTC material-connection guidance |
Source role to decision handoff
Use the map to create a concrete next request. The role names what a source can contribute; the evidence request tests the gap; the claim ceiling prevents a useful source from silently becoming the whole conclusion.
| Source role | Request before the decision | Claim ceiling until it arrives |
|---|---|---|
| Primary record owner | Retrieve the original record, definition, date range, coverage note, revision history, and denominator used in the sentence. | What the record contains or reports; not the full universe, prevalence, or cause. |
| Research producer | Request the instrument, population, recruitment path, mode, field dates, sample bases, weighting, quality checks, and limitations. | What the disclosed respondents or analyzed units show; not representative opinion without a justified frame. |
| Sponsor or vendor | Separate the interested party's metric definition and source files from independent validation, comparison rules, and outcome records. | A sponsored or vendor-reported result can be described, but it does not become independent proof or lift. |
| Platform or data owner | Document eligibility, exposure or match rules, observable fields, exclusions, and what the platform cannot see or compare. | Platform-observed activity within its measured universe; not causal impact across unseen users or channels. |
| Affected party or advocate | Seek a specific response, counter-source, affected-group context, and the denominator that separates experience from scale. | A reported experience or position may add context; it does not establish prevalence, motive, or consensus alone. |
Simulated Worked Example: a sponsored survey claim
This is a simulated example, not a real survey or a claim about any named organization. Assume a fictional release says, “62% of agency buyers plan to increase video spend next quarter.” The release identifies its sponsor and research producer, names agency buyers as the target population, gives an online mode, reports field dates, and says n=320. A fictional recruitment log shows 1,000 invitations and 320 completed responses. The release does not show recruitment rules, question wording, weighting, quality controls, or limitations.
| Source role or check | What the simulated record shows | Decision effect |
|---|---|---|
| Sponsor or vendor | Named and financially interested in a favorable category interpretation. | Keep the interest visible; do not let the sponsor supply both evidence and conclusion. |
| Research producer | Named, but its instrument, recruitment, weighting, and quality procedures are not disclosed. | Method role is present; method audit remains incomplete. |
| Direct participants | 320 respondents answered the online instrument. | Supports what those respondents said, not automatically what all agency buyers believe. |
| Primary record | The release gives 198 “increase” responses out of 320. | The result is inspectable as a respondent count, but the population frame is still unresolved. |
| Independent check | No outside benchmark, probability frame, or non-sponsor replication is supplied. | Do not upgrade a sponsor-released respondent result into a market-wide trend. |
Reproducible arithmetic: the stated percentage is 198 / 320 = 61.875%, which rounds to 62%. The simulated response rate is 320 / 1,000 = 32.0%, but that rate describes the fictional invitation log, not representativeness. A six-check audit scores record scope 1/1, sponsor visibility 1/1, method visibility 1/1, respondent denominator 1/1, population generalizability 0/1, and independent confirmation 0/1: 4 / 6 = 66.7%. That score is a workflow diagnostic, not statistical confidence.
Decision: hold the market-wide claim. The defensible sentence is, “A sponsor-released online survey reported that 198 of 320 respondents planned to increase video spend, but the public release does not establish how that result represents all agency buyers.” Do not say that agency-buyer demand is rising until the population frame, recruitment, wording, weighting, quality controls, limitations, and an independent comparison are available.
Reproduction notes and limits: count a disclosure field only when the release or a directly linked method note states it; do not infer missing methods from the sponsor’s reputation. Re-score if those records are added. The simulated denominator is fixed at the respondent level, so it cannot establish prevalence, causation, future spending, or a market trend. A different recruitment frame, nonresponse pattern, weighting scheme, or question wording could materially change the conclusion.
Quote-balance checks
Balance is not just counting quotes. A story can quote several people and still give one role more evidentiary weight than the record supports.
- Check whether the central claim is supported by records while the response is only summarized, or the reverse.
- Separate fact witnesses from interpretation sources before comparing quote length.
- Look for verb differences: "said," "claimed," "admitted," "warned," and "conceded" can tilt the reader before evidence appears.
- Notice whether caveats appear near the claim or only after the strongest frame is already established.
- Ask whether the omitted source role is obvious: data owner, affected party, method expert, regulator, sponsor, vendor, or counterfactual comparison.
Advertising measurement readouts
The same role map applies when a campaign result is being used as evidence. A platform, vendor, agency, brand, publisher, and analyst can each be useful while still seeing only part of the evidence trail.
| Measurement source | Can usually show | Still needs |
|---|---|---|
| Publisher or inventory owner | Placement IDs, context, creative delivery, eligible impressions, ad sizes, and page-level package logic. | Advertiser-side outcomes, comparison design, and independent lift evidence. |
| Ad server or platform | Served impressions, clicks, viewability fields, frequency, segments, and platform-visible conversions. | Outcome quality, unmatched users, cross-channel exposure, and incrementality. |
| Measurement vendor | Method note, match rule, model output, survey result, or attribution window. | Validation, uncertainty, leakage checks, and decision limits. |
| Advertiser or CRM owner | Lead status, sales stage, revenue fields, follow-up coverage, and duplicate handling. | Media exposure quality, audience selection, and counterfactual comparison. |
| Agency or analyst | Campaign interpretation, budget context, reporting structure, and next-action recommendation. | Clear separation between observed results, attributed activity, and causal claims. |
Fast workflow
1. Name the claim.Write the article, report, or readout claim as one sentence. Identify whether it is factual, comparative, causal, predictive, or normative.
2. List every source role.For each quote, link, chart, report, dataset, and dashboard, assign one role from the map. Do not let the same source quietly play every role.
3. Mark the strongest incentive.Financial, reputational, advocacy, access, and method incentives should be visible beside the claim they help support.
4. Find the missing role.Ask which source role would most likely weaken, narrow, or clarify the frame. If that role is absent, confidence should drop.
5. Calibrate the language.Use "shows," "suggests," "is consistent with," or "does not establish" according to the source trail, not according to how persuasive the narrative feels.
