When verifying the credibility of a source, there are four things to look for:
1. Authorship: The credibility of a source can be enhanced if the author is a known expert in the field or has published other reliable works on the topic. Checking the author's credentials, qualifications, and affiliations can also help to determine the credibility of the source.
2. Publication: The credibility of a source can be enhanced if it is published in a reputable and peer-reviewed journal, book, or website. Peer-reviewed sources are evaluated by experts in the field before publication, which adds to their reliability.
3. Currency: The credibility of a source can be enhanced if it is current and up-to-date. Information that is outdated may no longer be accurate, relevant, or reliable.
4. Objectivity: The credibility of a source can be enhanced if it is objective and free from bias. Sources that are biased may present information in a way that is intended to sway the reader's opinion or promote a particular agenda.
