The CRAAP test is one quick way of checking to see if your sources are credible and good to use for your research.
When trying to spot bias, ask yourself these questions:
Is it news? Opinion? Ad? Does it appeal to your emotions, or does it make you think?
Are the sources given? Are the sources associated with a political party or special interest group?
What’s the evidence, and how was it vetted? Is the source a document? Witness? Or is it hearsay/speculation?
Did the sources provided justify the conclusion or main point of the story?
Was there an aspect or point that was not covered or unclear that you are left wondering about?
Based on questions from the American Press Institute.
