Which factor does not contribute to assessing a source's credibility?

• A. Author credentials
• B. Publication date
• C. Publication venue
• D. Popularity on social media

Answer: (D)

Evaluating credibility hinges on the reliability and authority of the content, which comes from who wrote it, where it was published, and whether the information is current and well supported. The author’s credentials reveal subject expertise. A publication date matters because some fields evolve quickly and require up-to-date information, while for others, older work can still be credible. The publication venue signals quality control—peer-reviewed journals or reputable publishers typically indicate more careful vetting.

Popularity on social media does not measure the soundness of the argument or the accuracy of the information. A source can be highly popular regardless of its credibility, so this factor doesn’t reliably indicate trustworthiness.
