Which approach helps determine credibility when evaluating sources?

• A. Rely on a single source
• B. Check author credentials
• C. Ignore publication date
• D. Avoid any bias

Answer: (B)

Evaluating credibility starts with who produced the information. Knowing the author's background helps you judge whether they have the expertise to speak on the topic. Checking author credentials means looking at their degrees, professional experience, and where they work. If they hold relevant credentials or are affiliated with a respected institution, their explanations and conclusions are more likely to be reliable. This signal directly addresses whether the information comes from someone qualified to discuss it, making it the strongest cue for trustworthiness among the options.

Of course, credentials aren’t the whole story. It’s also important to see whether the work cites credible sources, uses clear evidence and sound methodology, and has been corroborated by other reputable researchers. Timeliness matters too, so the publication date can affect relevance. Bias can influence any source, so it’s useful to recognize potential biases and weigh the evidence accordingly rather than trying to avoid bias entirely.

So, checking author credentials is the best approach for judging credibility.
