Deductive reasoning plays a large role in choosing sources that are credible.
Does the article reflect more than one side of the story? Does the article come from a .org or .edu website? How is the source (news, social media) used by the contributor of information? I Is it a journal article? What is the source, as in who owns or funds the journal or article? Are the writers or providers of the information sharing credentials within or at the end of the article. If an article has an emotionally charged headline and appears to incite fear or feed a sense of unease, why would a reader consider it worthy? I prefer to direct library patrons to databases of journal articles and point them toward educational sites that may offer resources that are data driven. Supporting evidence is definitely necessary in a rapidly changing world mired with disinformation. Imparting this knowledge of how to find such evidence is an ongoing challenge. Providing options to public library users seems to offer a wider selection of valuable sources.
