In research and media literacy, what is the key criterion for evaluating sources?

• A. Publication date only.
• B. Reliability, credibility, relevance, and accuracy.
• C. Length, popularity, frequency of citation, and page count.
• D. Number of authors.

Answer: (B)

Evaluating sources in research and media literacy hinges on reliability, credibility, relevance, and accuracy. Reliability means the information comes from a dependable process and can be trusted to be consistent. Credibility depends on the author’s expertise and the publisher’s reputation, signaling that the source is worth trusting. Relevance checks whether the source directly informs your topic or question, rather than being tangential. Accuracy involves factual correctness and support through evidence, data, or verifiable citations.

Relying on publication date alone isn’t enough because a source can be current but biased or poorly supported, and a source can be old but still valid if well-documented. Similarly, length, popularity, or the number of authors doesn’t guarantee quality. In practice, you weigh who wrote it and where it’s published, look for supporting evidence and citations, check for potential bias, and see how well the information aligns with other reputable sources.
