What does it mean to 'qualify the source' in an argument?

Qualifying the source in an argument involves outlining the credentials or reasons for its credibility. This practice is essential in advocacy and debate as it helps establish the reliability and authority of the information being presented. When a source is qualified, it demonstrates that the argument is backed by someone who possesses expertise, relevance, or a solid reputation in the subject matter.

For instance, citing a study conducted by a respected researcher at a well-known university adds weight to the argument, as it helps the audience evaluate the trustworthiness of the information. By clearly stating who the source is and why they are credible, one enhances the persuasiveness of the argument and encourages the audience to accept the claims being made.
