No fake news checks should begin with two separate judgments: what kind of source is being used and whether that source deserves trust. A primary source provides direct evidence; a secondary source reports, interprets, or analyzes evidence. Neither label guarantees accuracy.
The most reliable assessment combines source type with four quality checks: authorship, evidence, context, and corroboration. This prevents the common mistake of accepting every primary source or dismissing every secondary source.
No fake news: Source type is not source quality
Source type describes a source’s relationship to an event or claim. Source quality describes how accurately, transparently, and fairly it handles that material. The two dimensions can overlap, but they are not interchangeable.
An official government statement is a primary source about what that government says, not automatic proof that its claims are true. A well-edited newspaper investigation may be a secondary source, yet it can provide stronger verification than an anonymous social-media post presented as firsthand evidence. Bias, missing information, incentives, errors, and deliberate manipulation can affect either type.
Primary vs. secondary sources: Definitions and examples
A primary source is original material created by a participant, witness, institution, or recording process close to the subject. Examples include:
- A full interview recording or eyewitness statement
- An original government record, court filing, speech, or company announcement
- Raw survey data, research results, photographs, or video captured at an event
A secondary source explains, evaluates, summarizes, or contextualizes primary material. Examples include a news article about a court filing, a fact-check examining a viral video, a research review, or an analysis of economic data.
Classification depends on the claim being examined. An official transcript is primary evidence of what a person said. A news report quoting that transcript is secondary evidence about the statement and may add useful context. A secondary source is not automatically weak, especially when it names its sources, links to original material, and distinguishes verified facts from interpretation.
How to evaluate non-credible sources: Authorship, evidence, context, and corroboration
Use the same quality questions for both source types:
- Authorship: Identify the author, publisher, relevant expertise, editorial standards, and possible financial or political interests. Anonymous material requires more verification, not automatic rejection.
- Evidence: Check whether the source supplies original documents, complete quotations, data, or an explainable method. Separate what the evidence shows from what the author infers.
- Context: Confirm the date, location, sequence of events, and full wording. Old photographs, cropped videos, and partial quotations can support a false claim while remaining genuine media.
- Corroboration: Look for independent reporting or records. Several websites repeating the same unsourced post do not count as independent confirmation.
Warning signs include sensational wording, certainty without evidence, attacks on critics instead of answers, hidden corrections, fabricated experts, and links that lead only to other copies of the claim. These signals indicate a need for further checking rather than proving a claim false by themselves.
A combined check for a suspect news story
- Isolate the claim. Write the precise statement being made, including the person, place, event, and date.
- Classify the source. Decide whether the item is firsthand evidence, a report about evidence, or a mixture of both.
- Trace the material. Follow links to the original document, recording, dataset, image, or statement. Confirm that it supports the published wording.
- Apply the four quality checks. Review authorship, evidence, context, and corroboration without treating source type as a credibility shortcut.
- Compare independent accounts. Check reputable outlets, official records, and specialist analysis for agreement, meaningful disagreement, or later corrections.
- Label the result carefully. Mark the claim as supported, contradicted, unverified, or misleading when the evidence does not justify a simple true-or-false judgment.
