Use fact-checking sites
In many cases, it is not necessary to go through the process of reviewing the accuracy of a source, since there are reliable fact-checking sites that provide the legwork for us. Use Snopes, factcheck.org, PolitiFact.com or the Washington Post Fact Checker first. However, even if the information is found to be factual, citizens must also consider the rest of the CRAAP test (or whichever reliability testing system you use) to determine whether the information is suitable for one's needs. Is it current, or is there more current reliable information on the topic? Who is the author, and are their credentials commensurate with the information need? Is the information relevant to the particular question at hand? And examining the purpose of the source can be very useful in helping to determine any underlying bias in the source. Also, facts that may be accurate can still be misleading, and following the information back to its original source might give you enough information to determine whether the context is neutral or slanted according to a set of beliefs. Finally, if you receive information that evokes an emotional response, stop, think, and check sources before responding or forwarding information to others.
