S933:  Information Evaluation Matrix; Tool to get Right Information & Fight Disinfo.

To filter and rate information as a citizen, you can create a systematic approach using a spectrum or matrix to evaluate sources based on truthfulness (True to False) and verification (Verified to Unverified). Here’s a practical guide to help you:

1. Understand the Axes of Evaluation

  • Truthfulness (X-Axis): Ranges from True (supported by evidence, consistent with facts) to False (disproven, contradictory, or fabricated).
  • Verification (Y-Axis): Ranges from Verified (sourced from credible, authoritative entities) to Unverified (lacking attribution or from dubious sources).

2. Create a Matrix or Spectrum

Visualize the information on a 2D matrix:

  • Top-Left (Verified + True): High-quality information from reputable, fact-checked sources (e.g., peer-reviewed studies, official reports).
  • Top-Right (Verified + False): Misinformation from credible outlets (e.g., errors in reporting, retracted articles).
  • Bottom-Left (Unverified + True): Potentially accurate but lacks credible sourcing (e.g., anecdotal claims that align with facts).
  • Bottom-Right (Unverified + False): Likely disinformation or rumors (e.g., unsourced social media posts, conspiracy theories).

3. Steps to Filter and Rate Information

Follow these steps to evaluate any piece of information:

#### A. Assess the Source

  • Who is the author or publisher? Check for credentials, expertise, or institutional backing (e.g., universities, government agencies, established media).
  • Is the source primary or secondary? Primary sources (e.g., official documents, raw data) are more reliable than secondary interpretations.
  • Red flags: Anonymous authors, sensationalist websites, or sources with a history of bias or falsehoods. B. Check for Verification
  • Is there evidence? Look for citations, links to data, or references to reputable studies.
  • Cross-reference: Verify claims against multiple independent sources. Use fact-checking sites like Snopes, PolitiFact, or FactCheck.org.
  • Transparency: Credible sources disclose their methods and limitations. C. Evaluate Truthfulness
  • Consistency: Does the information align with known facts or other verified sources?
  • Logic and plausibility: Does the claim make sense, or does it rely on improbable assumptions?
  • Bias check: Look for loaded language, one-sided narratives, or omissions that skew the truth. D. Rate the Information
  • Assign a position on the matrix based on your findings. For example:
    • A peer-reviewed study cited by multiple outlets: Verified + True.
    • A viral post with no source but plausible claims: Unverified + Potentially True.
    • A debunked claim from a fringe blog: Unverified + False.

4. Tools and Resources

  • Fact-Checking Sites: Snopes, PolitiFact, BBC Reality Check.
  • Source Evaluation Tools: Media Bias/Fact Check, AllSides, or the CRAAP Test (Currency, Relevance, Authority, Accuracy, Purpose).
  • Search Engines: Use Google Scholar or PubMed for academic sources, or X for real-time public sentiment (cross-check claims).
  • Digital Literacy Guides: Resources from organizations like the News Literacy Project or Stanford’s Civic Online Reasoning.

5. Practical Tips

  • Slow down: Avoid sharing or believing information impulsively. Take time to verify.
  • Diversify sources: Consult outlets with different perspectives to avoid echo chambers.
  • Check dates: Outdated information can be misleading.
  • Be skeptical: If a claim seems too good, bad, or shocking to be true, it probably is.

6. Example Matrix Application

Suppose you read: “A new study proves coffee cures cancer.”

  • Source: A blog post with no author, linking to no study (Unverified).
  • Evidence: No study found; reputable sources like the NIH say coffee has no such effect (False).
  • Matrix Position: Bottom-Right (Unverified + False). Contrast with: “WHO reports rising global cancer rates.”
  • Source: WHO’s official website with data (Verified).
  • Evidence: Matches reports from CDC, other agencies (True).
  • Matrix Position: Top-Left (Verified + True).

7. Continuous Improvement

  • Reflect: Track your evaluations to see where you were misled or correct.
  • Learn: Stay updated on common misinformation tactics (e.g., deepfakes, cherry-picking data).
  • Engage critically: Discuss findings with others to refine your judgment.

By systematically applying this matrix and using reliable tools, you can better navigate conflicting information and make informed decisions as a citizen.

CRAAP Test

The CRAAP Test is a widely used framework for evaluating the credibility and reliability of information sources, particularly in academic and research contexts. It stands for Currency, Relevance, Authority, Accuracy, and Purpose. Below is an expanded explanation of each component, with practical guidance on how to apply it to assess information on your True/False and Verified/Unverified matrix.


1. Currency: The Timeliness of the Information

  • What to Assess:
    • When was the information published or last updated?
    • Is the publication date relevant to your topic?
    • Are there newer studies or developments that might supersede this information?
  • Why It Matters:
    • Outdated information can lead to incorrect conclusions, especially in fast-evolving fields like technology, medicine, or current events.
    • Timeliness contributes to the truthfulness axis—if the information is outdated, it may no longer be true.
  • How to Apply:
    • Check the publication date on articles, websites, or studies. For example, a 2010 study on climate change might not reflect the latest data.
    • Look for updates or revisions. On websites, check for a “last updated” timestamp.
    • If the topic requires current data (e.g., election results, scientific discoveries), prioritize recent sources.
  • Matrix Impact:
    • Outdated information might shift a source toward False on the truthfulness axis, even if it’s from a verified outlet.

2. Relevance: The Importance of the Information to Your Needs

  • What to Assess:
    • Does the information directly address your question or topic?
    • Is it at an appropriate level (e.g., not too basic or too advanced)?
    • Is the scope of the source relevant to your context (e.g., local vs. global)?
  • Why It Matters:
    • Irrelevant information, even if true, can mislead by distracting from the core issue or providing incomplete context.
    • Relevance ensures the information is useful for your specific purpose, which indirectly affects its truthfulness in context.
  • How to Apply:
    • Define your research question clearly. For example, if you’re investigating “vaccine efficacy in 2025,” a source discussing vaccines from 2015 may not be relevant.
    • Skim the introduction, abstract, or summary to see if the content aligns with your needs.
    • Consider the audience of the source. A blog post aimed at children might oversimplify a complex issue, making it less relevant for an in-depth analysis.
  • Matrix Impact:
    • Irrelevant information may not directly affect the Verified/Unverified axis but could skew the True/False axis if it misrepresents the issue due to poor fit.

3. Authority: The Credibility of the Source

  • What to Assess:
    • Who is the author, publisher, or organization behind the information?
    • What are their credentials, expertise, or qualifications?
    • Is the source affiliated with a reputable institution (e.g., university, government agency)?
  • Why It Matters:
    • The authority of the source directly impacts its verification status. A well-credentialed author or reputable outlet is more likely to be verified.
    • Lack of authority often correlates with unverified or unreliable information.
  • How to Apply:
    • Look for the author’s name and research their background. For example, a medical claim by a doctor with a history of peer-reviewed publications is more authoritative than one by an anonymous blogger.
    • Check the publisher or website. Peer-reviewed journals, government reports (e.g., CDC, WHO), or established news outlets (e.g., BBC, Reuters) are generally more authoritative.
    • Be cautious of sources with conflicts of interest, like a company promoting its own product without independent validation.
  • Matrix Impact:
    • A source with strong authority (e.g., a peer-reviewed journal) leans toward Verified on the Y-axis.
    • A source with no clear author or dubious credentials (e.g., a random blog) leans toward Unverified.

4. Accuracy: The Reliability and Correctness of the Content

  • What to Assess:
    • Is the information supported by evidence (e.g., data, citations, references)?
    • Does it align with other credible sources?
    • Are there obvious errors, exaggerations, or inconsistencies?
  • Why It Matters:
    • Accuracy directly determines where the information falls on the True/False axis.
    • Inaccurate information, even from a verified source, can still be false.
  • How to Apply:
    • Look for citations or links to primary sources. For example, a news article claiming “90% of people support X” should link to a survey or study.
    • Cross-check the information with other reputable sources. If a claim about climate change contradicts NASA or NOAA data, it’s likely inaccurate.
    • Watch for red flags like sensational language (“shocking truth!”), lack of evidence, or logical fallacies (e.g., correlation mistaken for causation).
  • Matrix Impact:
    • Accurate information supported by evidence leans toward True.
    • Inaccurate or unsupported claims lean toward False, regardless of the source’s authority.

5. Purpose: The Reason the Information Exists

  • What to Assess:
    • What is the intent of the source—to inform, persuade, entertain, or sell?
    • Is there bias, agenda, or propaganda influencing the content?
    • Does the source present multiple perspectives, or is it one-sided?
  • Why It Matters:
    • The purpose can affect both truthfulness and verification. A source with a clear agenda might distort facts (False) or lack credibility (Unverified).
    • Understanding intent helps you identify hidden biases that might skew the information.
  • How to Apply:
    • Identify the tone and language. Objective, neutral language (e.g., in a scientific paper) suggests a purpose to inform, while emotional or persuasive language (e.g., in an opinion piece) suggests bias.
    • Check for sponsorship or funding. For example, a study on a drug funded by the drug’s manufacturer may have a conflict of interest.
    • Look for balance. Does the source acknowledge opposing views, or does it cherry-pick data to support a narrative?
  • Matrix Impact:
    • A source with a clear agenda (e.g., a political ad) might lean toward False if it distorts facts and Unverified if the bias undermines its credibility.
    • A source aiming to inform with balanced perspectives (e.g., a peer-reviewed article) leans toward True and Verified.

Applying the CRAAP Test to the Matrix

Here’s how the CRAAP Test components map onto your True/False and Verified/Unverified matrix:

  • Currency: Affects Truthfulness. Outdated information may no longer be true, even if it was once accurate.
  • Relevance: Affects Truthfulness indirectly. Irrelevant information might mislead in context, making it effectively false for your needs.
  • Authority: Affects Verification. Credible, authoritative sources are more likely to be verified.
  • Accuracy: Affects Truthfulness. Evidence-based, consistent information is true; unsupported or contradictory information is false.
  • Purpose: Affects both axes. A biased purpose can make information false (distorted facts) and unverified (lacking credibility).

Example Using the CRAAP Test

Let’s evaluate a claim: “A new study shows that eating chocolate daily prevents heart disease.”

  1. Currency:
  • The article is from 2023. A quick search shows newer studies from 2025 that contradict this claim with more rigorous data.
  • Impact: Potentially False due to outdated information.
  1. Relevance:
  • The article focuses on chocolate’s effects on heart disease, which matches your topic.
  • Impact: Relevant, so no negative effect on truthfulness.
  1. Authority:
  • The article is on a health blog with no author listed. The “study” isn’t linked, and the blog has a history of promoting fad diets.
  • Impact: Unverified due to lack of authority.
  1. Accuracy:
  • The claim isn’t backed by a cited study. Cross-checking with the American Heart Association shows no conclusive evidence linking daily chocolate consumption to heart disease prevention.
  • Impact: False due to lack of evidence and contradiction with credible sources.
  1. Purpose:
  • The blog post ends with an ad for a chocolate subscription service, suggesting a commercial agenda.
  • Impact: Bias leans it further toward False and Unverified.

Matrix Position: Unverified + False (Bottom-Right quadrant).


Tips for Using the CRAAP Test

  • Combine with Other Tools: Use the CRAAP Test alongside fact-checking sites (e.g., Snopes) or source evaluation tools (e.g., Media Bias/Fact Check).
  • Be Systematic: Apply each criterion consistently to avoid cherry-picking.
  • Document Findings: Keep notes on how each source scores to refine your evaluation process over time.
  • Adapt to Context: Some criteria may weigh more heavily depending on your needs. For example, in a breaking news scenario, Currency might be more critical than Authority.

By applying the CRAAP Test, you can systematically evaluate information and place it accurately on your True/False and Verified/Unverified matrix, ensuring you rely on the most credible and accurate sources available.
