Source Credibility and Perspective
How can we judge whether a source is useful and understand its perspective?
Activate what you know
If two signs give different closing times for a museum, name one detail you would check before choosing which to follow
- credibilitythe degree to which a source deserves confidence for a particular claim
- perspectivea point of view shaped by a person’s position and experience
- purposethe reason a source was created
- expertiserelevant knowledge or skill
- claima statement presented as true
- corroborateto compare sources to see where evidence agrees or differs

Useful Sources Earn Confidence
Credibility is not a sticker that says a source is always trustworthy. An official transit schedule is strong evidence for today’s bus times, but it may be weak evidence for why riders like a route. A rider survey could help with experiences, while agency records could help with schedules and costs. Check who created the source, when, for what purpose, and with what evidence. Expertise should match the claim. A bridge engineer may know bridge design, but that expertise does not automatically make the engineer an expert on every part of community history

Perspective Is Not the Same as Falsehood
Every source has a perspective because every creator has a position, experience, and purpose. Perspective can shape which facts are noticed or left out. It does not automatically make a source dishonest. Researchers ask what the perspective helps reveal and what else is needed. Corroboration means comparing sources. Agreement can strengthen a detail, while disagreement becomes a question to investigate. Two sources may use different dates, boundaries, or definitions, so first check whether they are truly describing the same thing. For instance, a construction notice and a resident’s account can both be credible while answering different questions: the notice establishes the official plan, and the account documents one lived effect
Credible for This Claim
Always finish the judgment: ‘This source is more credible for ____ because ____.’ Avoid labeling an entire source simply good or bad
Replace ‘Can I Trust It?’
Ask two sharper questions: ‘Trust it for which claim?’ and ‘What evidence would let me check?’
Official Does Not Mean Complete
Official records can be authoritative for laws, dates, or agency data while still leaving out lived experiences or past errors
Compare Two Notices
Compare a current official park notice with an older visitor post. Judge each for opening hours, visitor experience, and recent construction. Explain which source fits each claim
Source credibility depends on the claim, creator, date, purpose, expertise, and evidence. Perspective shapes what a source reveals, and corroboration strengthens conclusions
Practice and answer guide
Work through all 10 questions. Open an answer only after you have written or explained your response.
- 1. Which source is strongest for today’s library hours? A. the library’s current official page B. an undated comment C. a ten-year-old flyer
Check answer
The library’s current official page
- 2. Name the five checks used in the first visual
Check answer
Creator, expertise, date, purpose, and evidence
- 3. Why does expertise need to match the claim?
Check answer
Knowledge in one field does not prove knowledge about an unrelated claim
- 4. Identify one perspective a wheelchair user may bring to a street plan
Check answer
The user may notice curb cuts, path width, surface condition, or obstacles that affect access
- 5. Does having a perspective automatically make a source false? Explain
Check answer
No. Perspective shapes attention and interpretation but does not by itself prove a claim false
- 6. What does corroborate mean?
Check answer
Compare sources to see where evidence agrees or differs
- 7. Two maps disagree. Name one feature to check before deciding why
Check answer
Accept date, scale, boundary, legend, source, projection, or whether both maps show the same place and purpose
- 8. Choose one source named in this lesson. Complete: This source is credible for ____ because ____
Check answer
The response must name the source and claim and support the judgment with creator or expertise, date, purpose, or evidence
- 9. Which purpose should make a reader check product claims especially carefully? A. selling B. recording a date C. labeling a public room
