Which factor can help determine the reliability of a source?

The author's reputation and background play a critical role in assessing the reliability of a source. A reputable author, meaning someone with relevant qualifications, experience, and a history of credible work in a field, is more likely to provide accurate, well-supported, and trustworthy information. Factors such as academic credentials, prior publications, and professional affiliations can signal to the reader that the author possesses expertise and authority on the subject matter.

In contrast, popularity among peers might not indicate the accuracy or reliability of the information presented, as popularity can stem from various non-academic factors. Readability of the material, while important for audience comprehension, does not guarantee that the content is valid or credible. Similarly, the country of publication may affect certain contextual aspects but does not directly relate to the reliability of the information itself, as valuable research can emerge from any country, regardless of its reputation. Therefore, assessing the author's credentials and background is a fundamental approach to determining the credibility of a source.
