WRT 102 - Downtown (Katherine Davis): Evaluating Sources & their Claims

Credibility assessment

What is credibility evaluation?

Credibility evaluation of a source is a stand-in for a direct evaluation of the truth of a key statement. Credibility assessment is an indirect assessment of what matters: the truth of the statement that the authors are responsible for.


When a credible source makes a statement . . .

  • The author KNOWS the truth of the statement

  • The author TELLS the truth as they see it, without distortion.


In evaluating credibility, there are two ultimate questions to answer, and we look for objective indicators:

  • How does the author know the statement is true? Are they in a good position to do so?

  • Is the author motivated/incentivized to tell the truth without distortion?
