Governing standards
Use when a standard, rule, policy, or technical specification defines the claim.
What primary standards define WCAG conformance, and how do they distinguish requirements from supporting guidance?Use this evidence-first question
A practical source guide
Choose the evidence your question needs.
A source is useful when it fits the claim, date, place, and decision—not simply because a link exists. Choose a source type, carry the example into Search, then review or change it before you submit.
Guides and public Explore paths are free. Search shows the available balance before submission and uses a credit only when you choose to run the question. Review exactly when a search credit is used.
Five useful evidence choices
Match the source to the job.
Official records
Use when the answer depends on current public records, statistics, decisions, or agency definitions.
What do current official records show about U.S. heat risk, and which agency definitions or dates limit the comparison?Use this evidence-first question
Original research
Use when methods, samples, dates, limitations, and later review matter as much as the finding.
What primary studies compare remote and in-person collaboration, and what do their methods and limitations allow us to conclude?Use this evidence-first question
Health evidence
Use when health claims need current evidence, qualified review, clear limits, and an explicit boundary between general information and individual medical advice.
What does current evidence say about sleep duration and adult health? Separate population research from individual medical advice, identify who reviewed the guidance, and show when each source was updated.Use this evidence-first question
Context and analysis
Use when facts and sources need to be separated from interpretation, uncertainty, and a practical decision.
What are the tradeoffs of open-source software for small teams? Separate documented license and maintenance facts from practical judgment.Use this evidence-first question
A reusable source note
Record the evidence role before you cite it.
Reputation alone does not show what a source can support. Save these four fields so the source stays attached to the right claim and its limits remain visible.
- Source role
- Direct evidence, governing rule, dataset, synthesis, or commentary.
- Producer
- The person or organization and its relationship to the evidence.
- Method and date
- How the record or result was created and when it was produced or updated.
- Claim boundary
- The exact statement it supports—and what it cannot establish.
A direct source-fit answer
Can one source establish every kind of claim?
No. A source is useful only when its authority, method, date, place, population, and scope fit the exact claim. Standards, official records, original research, health evidence, and analysis do different jobs, so a responsible answer may need more than one source type and must keep limits visible.
Human review still matters
A citation is a starting point, not automatic proof.
NIST's AI Risk Management Framework treats validity, reliability, accountability, transparency, explainability, and human review as connected trustworthiness concerns. For health information, NIH also recommends checking the supporting evidence, author or reviewer credentials, and update date. Dystiny makes source paths explorable; you still decide whether each source fits the claim and context.

See how Dystiny keeps the clear answer, sources, and visual paths distinct.
- Authority: who created the source, under what role or method?
- Fit: does it address the exact claim, population, place, and timeframe?
- Limits: what is missing, uncertain, disputed, or outside scope?
- Currency: could a newer standard, record, or study change the answer?
