When evaluating a source, one criterion a writer should use is the credibility and reliability of the source. This includes assessing the author's expertise and reputation, as well as considering the publication or platform where the source is found. The writer should also examine whether the source provides evidence-based information, has a clear bias, or presents a balanced viewpoint. Overall, prioritizing credibility and reliability is essential to ensure the accuracy and validity of the information being used in a written piece.
