What role does evaluating an author's credentials play in determining credibility?

Evaluating an author's credentials is crucial in determining their credibility primarily because it helps assess trustworthiness. The credentials of an author—such as their educational background, professional experience, and expertise in the subject matter—offer insight into their qualifications to discuss a particular topic. When readers can verify that an author possesses relevant credentials, they are more likely to trust the information presented, forming a solid foundation for reliable interpretation. This process enhances the reader's ability to critically evaluate the information and decide whether to accept or question the author's claims based on established knowledge and experience.

The other options, while related in some way to understanding an author's work, do not directly address the primary reason for assessing credibility through credentials. For instance, establishing intent or examining writing style can provide context but do not inherently confirm an author's reliability as a source. Comparing authors might offer additional perspectives but is not the main factor in evaluating the credibility of a specific author's work.
