Put everything you read, and especially everything you share, through the CRAAP test!
Currency - Can you find when the information was published and is it current?
Reliability - Is the article supported by evidence, with links, footnotes, or sources cited? Can it be confirmed by other sources? Check other sources to see what they are saying. The Associated Press is a good traditional news outlet to check.
Authority - Who wrote the information and what are their credentials, such as college degrees or work experience? Are they an expert in their field?
Accuracy - Is the information peer-reviewed or fact checked? Does it seem unbiased and free of emotion? Are there spelling, grammar, or typographical errors?
Purpose - Why does this information exist - is it to inform or teach, or is it to sell or persuade? Is it just entertaining? Do the authors make their intentions clear? Is the information fact, opinion, or propaganda? Does it appear objective and impartial, or is there a political, ideological, cultural, religious, institutional or personal bias?
